2 INTRODUCTION
This system administration manual covers the following Atherton sterilizers
Tangent Tiger
Tangent Gorilla
All Cyber Series Sterilizers
As such it is important when reading this manual to refer only to the sections
that relate to your unit. To aid the reader where appropriate we have used the
name Tangent to refer to the Tangent sterilizers and the name Cyber to refer
to the Cyber Series units. As a general note all functionality available in the
Tangent Gorilla is available in the Tangent Tiger. However due to the
extensive range of features in the Cyber Series it is important to refer only to
the items that relate to your model sterilizer, for example you may have a
double door unit but unless you have a barrier seal with door security the
section on door security is not relevant to your unit this section only refers to
the operation of the doors for units which have a barrier seal with back-up
compressed air. If you have any queries regarding the features of your
Atherton sterilizer please contact you Atherton representative.
2.1
GENERAL NOTE ABOUT TOUCHSCREEN DISPLAY
Your Atherton sterilizer is fitted with either one or two (double door units),
state of the art hi-resolution Beijer Electronics Exter T70 or T100
touchscreens. To aid with system navigation a uniformity of function has been
programmed into the design of the screen layout. For the most common
screens the touch screen area has been divided into three sections, a title bar,
the main body area and the bottom navigation bar.
2.2
TITLE BAR FUNCTIONALITY
The area at the top of the screen is referred to as the title bar for “most”
screens this area acts as a return to previous screen function. Unfortunately
not all screens can have this functionality as it is necessary for some system
functionality that the user complete a series of tasks which may require a set
navigational sequence. However for the vast majority of screens touching the
title bar will return the user to the previous screen. For example from the Main
Menu if the user selects the Help Menu button the Help Menu screen is
displayed, then to return to the Main Menu the user can either choose the
button at the bottom of the screen or use the title bar:
HELP MENU
10 of 73
UM 34 Rev 0
Atherton Sterilizer – System Administration Manual
04/02/2009
Selecting the title bar from the Help Menu returns the user to the Main Menu.
2.3
MAIN AREA FUNCTIONALITY
The middle area of the screen is referred to as the main area and contains the
functionality buttons and any display items. For example the main area of the
Analogue Readings screen contains the analogue input values displayed in
dial form:
2.4
BOTTOM NAVIGATION BAR
The bottom area of the screen is reserved for navigation and committing a
change to the memory. Using the above example of the Analogue Readings
screen the bottom navigation bar allows the user to return to the previous
screen or the Main Menu – referred to here as the Home Screen or the Help
Menu:
2.5
CYCLE START SCREENS
Once a cycle has been selected from the cycle family screens the system
displays the parameters for the chosen cycle. If the user is satisfied that the
parameters are appropriate the user then selects ‘START CYCLE’.
11 of 73
UM 34 Rev 0
Atherton Sterilizer – System Administration Manual
04/02/2009
The cycle start screens all follow the same format – the parameters are
displayed in the centre of the screen, a user with the required access level can
alter the parameters for all variable cycles. The user then has the option of
either starting a cycle or cancelling and returning the cycle family screen.
2.6
OPERATING SCREENS
The operating screens display the sterilizer state while running a sterilizing or
test cycle. The layout of all the operating screens is similar; with three
sections in the green background area of the screen and a lower navigation
bar. In the green background area the three sections are
The parameters section at the top which is unique for each cycle
The temperature and pressure section in the middle.
The cycle stage, elapsed time and warning text section in the lower third.
Using the navigation bar the user can view a cycle trend, the full set of
temperature and pressure readings, and a system schematic, as well as abort

the cycle, there is also a new feature to view the remaining time for the cycle,
this button is only visible for Pre Vacuum cycles and only after pulsing stage
has completed.
Complete view of Cycle operating screen:
2.7
TREND SCREEN
The cycle trend screen has the capability to display historical information. If
the user touches the middle of the trend graph the trend stops updating and a
navigation bar appears at the base of the trend graph. Use the arrows to
move back forward in time and then to zoom in or out.

3 SECOND (SLAVE) SCREEN FUNCTIONALITY – DOUBLE DOOR
MODELS ONLY
The slave screen is designated as the touchscreen which is located at the end
with the printer. For safety reasons and to preserve the integrity of the clean
end/dirty end designation the unit can only be configured from the master
touchscreen. While the user is accessing the administration screens from
the master touchscreen the following screen is displayed at the slave end:
Under all other circumstances the display at the slave screen is similar to the
display at the master screen.
Functionality available at the Slave Screen (also available at the Master):
Cycle initiation – start cycles.
Abort cycles.
Set PLC clock – which affects both screens and the print out.
Open/close either door – dependent on unloading end designation.
Re-print last cycle.
Access the analogue values – temperatures and pressure.
Functionality available only from the Master Screen:
Configure favourite cycles.
Access the administrator menu.
Set unloading end.
3.1
GENERAL NOTE ABOUT “THIS END” “OTHER END” DISPLAY
While the doors are driving or the user is initiating a door to open or close the
screen will display a message stating that either this or the other door is
15 of 73
UM 34 Rev 0
Atherton Sterilizer – System Administration Manual
04/02/2009
driving. The designation refers to the door at the end at which the user is
standing. For example if the user is standing at the slave screen and the door
at the master screen end is driving open then the screen message will display
Now Opening Other Door:
Alternatively if the user is standing at the slave screen end and the door at
that end is opening then the screen will display Now Opening This Door:
In a similar manner if the user is standing at the slave touchscreen and wants
to command the door at the other end to close then the following screen will
be displayed. You will notice that only one button is visible this is because in
this instance the user has setup the slave end as the clean end. In this
configuration the button for driving the clean end is not displayed. This way
the clean end cannot be opened without reversing the clean end/dirty end
designation.

4 DOUBLE DOOR OPERATION – UNITS WITH BARRIER SEAL
Because of the need to maintain the integrity of the separation of the clean
end from the dirty end of the sterilizer attention must be paid to the way in
which the user designates the end through which the sterilizer is to be
unloaded – this is referred to as the clean end. The loading end is the dirty
end, in keeping with the fact that items entering the sterilizer are deemed nonsterilized – dirty.
The system acts to maintain a complete barrier between the two ends to do
this whenever any door is shut its gasket is engaged, hence when both doors
are shut both gaskets are engaged. This means that for a door to drive, the
sterilizer must first retract the gasket to free the door to allow the door actuator
to freel drive the door. To do this the system starts the vacuum pump until
the pre-determined chamber vacuum level is achieved at this point the
gaskets are both retracted although the face of the gasket is still protruding
sufficiently to engaged against the surface of the door, thus preserving the
barrier. Now the system closes the compressed air and steam line to the door
which has been requested to open. The system then releases the chamber
back to atmospheric pressure with the gasket at the other end inflated to
engage against the sterilizer door. In this way the system can now drive open
the required door..
This process of engaging one end’s gasket and retracting the other end’s
gasket is also undertaken after a cycle is completed. For a passed cycle the
system can automatically open the unloading end door. For a failed cycle the
loading end is opened while the unloading end is sealed with the gasket
engaged. At the end of test cycle the only loading end is able to be opened.
4.1
SETTING THE UNLOADING END
To set the unloading end the user must be logged in at Administrator Level
and have switched to the Administrator Menu screen:
18 of 73

Using the menu items on the right hand side of the screen select the double
door button. If the doors are not shut the user will be advised that both doors
must be closed before accessing this area:
Using the doors button close the doors and then return to this area through
the Administrator Menu:
An arrow (not shown above) will indicate the direction of use for the sterilizer,
the arrow which appears on the screen is intended to indicate the loading and
unloading ends.

5 LOW LEVEL BAS INTERFACE
Please note this section is only relevant for systems which have been
configured with the building automation system interface.
The Sterilizer has the ability to interface with any building automation system
(BAS) via 12 designated low level outputs. The outputs are provided in
standard volt free contact form and are wired into the Sterilizer control panel
connected to the designated Omron PLC card.
For connection details and a wiring diagram please contact Atherton.
Each output is switched on for 30 seconds each time a corresponding fault
condition occurs. The following table indicates the switching sequence and
corresponding fault condition.

7 CONDENSATE RETENTION
Units that are fitted with condensate retention capabilities have an additional
button located on their home screen. This button is used to run a modified
Lab Vac cycle such that the condensate drain line will remain closed until a
passed cycle is achieved.
7.1
CONDENSATE RETENTION – SEQUENCE OF OPERATION
When a condensate retention cycle is selected from the home screen the unit
immediately shuts the condensate drain motorised ball valve, if the user
selects Cancel Cycle then the condensate drain opens, if however the user
Starts the cycle then once the doors have closed the steam supply to the
condensate drain heater is turned on. The unit will then begin the Lab Vac
cycle with the unit set in heated condensate retention mode.
7.1.1 Condensate Retention - PASS
If a condensate retention cycle passes then the unit will open the condensate
drain at the completion of the sterilizing stage, this will also disable the
solenoid to the condensate heating system
7.1.2 Condensate Retention – FAIL
If a condensate retention cycle fails to successfully complete the sterilizing
stage then the unit will maintain the condensate that was collected during the
cycle in the condensate drain and will keep the heating to the condensate
enabled until a cycle is successfully completed. This means that if a user
opens the door the condensate which has formed in the base of the chamber
may spill out. The remaining condensate will remain in the condensate
collection drain pipe until a new cycle is started and it successfully completes
the sterilizing stage.

Atherton Sterilizer – System Administration Manual
04/02/2009
7.2
CONDENSATE RETENTION – CYCLE SETTINGS
By selecting the special condensate button from the home screen the user is
setting the unit into condensate retention mode in preparation for a modified
Lab Vac cycle:
The Lab Vac cycle sequence is similar to a standard SP Lab Vac cycle with
the exception that the condensate drain line and condensate drain heater are
controlled in accordance with the previously described sequence.
7.2.1 Lab Vac Cycle Parameters
By selecting the “Thumbs Up/Down” button next to either Pre Vac or Post Vac
the screen will change to the Pre Vac & Post Vac Parameters screen as
shown on the next page. From this screen the user is able to modify the Pre
Vacuum and Post Vacuum settings for the Lab Vac cycle.
When you are satisfied with the parameters select the Return button at the
bottom of the screen then start the cycle.

Atherton Sterilizer – System Administration Manual
04/02/2009
7.2.2 Pre Vac Parameters
The Pre Vac parameters control the way in which the system achieves the pre
steam charge vacuum level.
Pre Vac Max Value: - This is the maximum vacuum level that the system will
incrementally draw down to.
Vacuum Increment: - This is the incremental vacuum level that the system
will draw each time the vacuum hold time has expired. During a vacuum
increment sequence the system opens the chamber dump motorised ball
valve and evacuates the chamber so as to achieve the next incremental
vacuum level. NOTE you must enter a positive value for the vacuum
increment.
Vacuum Hold Time: - This is the delay between vacuum increment steps.
7.2.3 Post Vac Parameters
The Post Vac parameters operate in the same way as the Pre Vac parameters
except they are applied to the exhaust stage which occurs after the Sterilizing
stage.
7.2.4 Enabling Or Disabling Pre Vac, Post Vac
Use the “YES NO” buttons to enable or disable either Pre Vac or Post Vac:

CUSTOMISED OPERATION
From the Operator Help Menu it is possible to customise many of the
operational features of your Sterilizer
There are two ways to navigate through the customisable options; the first is
to select the ‘CUSTOMISE STERILIZER OPERATION’ button on the
Administrator Menu Screen; the second is to simply select the item of
customisation from the buttons that appear on the left hand side of the screen:
OPTION 1
OPTION 2
Requires set navigation.
Allows direct access.
Option 1 navigates the user to through the complete customisation process,
however the user can elect to save settings at any stage and this will exit the
user from the customisation process. Option 2 allows the user to access
simply the setting of interest and SAVE the changes.
It is suggested that initially the user select Option 1; select the ‘CUSTOMISE
STERILIZER OPERATION’ button to familiarise themselves with all the
available customisation features. After the user is more comfortable with the
37 of 73
UM 34 Rev 0

available options it is more expeditious to use option 2. Described below are
all the customisation features.
8.9.1 Data Logging & Sterilizer Name
The intervals for data Logging can be selected for different family groups.
Set the Data Logging interval required for each family group
You can also decide if you require Data Logging or not during the steam
charge and sterilisation stages.
U” if you require Data Logging.
Select “
If no Data Logging is selected, Data Logging will be off.
To proceed with further customisation select either ‘ABORT PARAMETERS’
or ‘STANDBY & FLUID PROBE’.
8.9.1.1 Sterilizer Name
Also available on the Data Logging screen is the facility to name your
sterilizer, this function will see the system print the 10 digit text and the
corresponding bar code for the text in the text box at the start of each cycle. A
test of the function can be initiated to view a sample of the output. The bar
code is Code 39 format.

Automatic warm-up can be enabled for the required days. It will begin at the
time designated in the top right hand side of the screen.
Select save to commit the changes. This will drop you back to the main
screen to proceed with further customisation.
8.9.3.1 Auto Start Day Sequence
New to the Atherton sterilizer system is an Auto Start Day Sequence, this
feature will set the system into a mode where when the automatic warm-up is
completed the system will begin a Leak Rate test. If the Leak Rate test is
successful the unit will then proceed to the start Bowie & Dick cycle screen.
8.9.4 Abort Parameters
It is possible to set the Drying/Vapour Removal time when an emergency
abort has been activated. This will force the system to override the
programmed drying time for cycles that have been aborted. This feature is
useful for quickly gaining access to the aborted cycle’s sterilizer contents so
as to remove them, reload the unit and start another cycle without having to
wait for the long dry time that may have been programmed for the cycle.

UM 34 Rev 0
Atherton Sterilizer – System Administration Manual
04/02/2009
8.9.5 Theoretical Pressure
A new feature that has been added to Atherton sterilizers is the ability for the
sterilizer to calculate the theoretical hi and low pressure allowance for
sterilizing setpoints of 121°C and 134°C.
When enabled the system will calculate the hi and low pressure values for
each 0.1°C increment of temperature during sterilizing stage, it will then
compare this calculated value with the current operating chamber pressure. If
the chamber pressure is outside of this range the unit will fault the cycle and
report a “Pressure Out of Range” abort.
The criteria for the calculation of the upper and lower limits for the pressure
are programmed in accordance with AS1410-2003, Section 3.25.1 (k) with the
temperature used as the input value determined by the allowance stated in
AS1410-2003, Section 3.26.1 (j).
8.9.6 Auto Holding Time
The sterilizing holding time can be set to automatically increase to a minimum
level by turning on the Automatic Minimum Holding Time feature.
41 of 73
UM 34 Rev 0
Atherton Sterilizer – System Administration Manual
04/02/2009
This feature causes the system to look at the sterilizing holding time at the
start of a cycle. If the holding time is less than the designated minimum time
(set by Atherton Service Technician in consultation with an authorised
representative) the system will automatically increase the hold time to the new
minimum. If the value is greater than the designated minimum then the
system does not change the value.
The following screen is an example of the pre-programmed temperature
holding time mappings. These are the values that the CSSD, ward manager,
laboratory specialist or facility representative can set in conjunction with an
Atherton Service Technician. In no way does this constitute a removal of care
on behalf of the user to ensure that the correct cycle settings are set for the
intended sterilization process. These are merely minimum holding times
which apply for a designated sterilizing temperature it is the user’s
responsibility to ensure that these holding times are appropriate for the
intended use of the sterilizer. Atherton cannot be held responsible for
inappropriate matching of sterilizing temperature to holding time. We suggest
these values are validated by your medical staff, and approved by an
authorised sterilization services expert. Our service is provided only as a
facilitator. This screen cannot be accessed without our service password.
The values shown in the above screen are conservative holding times and
should be edited at the time of commissioning of the unit.
8.9.7 Daily Log Print Out
The Sterilizer Rat daily log function can be reset at any time. To change the
default reset time, alter the value at the bottom of the screen. Also the daily
log function can be disabled by pressing the tick or cross adjacent to the
“thumbs-up” signal.
42 of 73
UM 34 Rev 0
Atherton Sterilizer – System Administration Manual
04/02/2009
To print a daily log return to the main help menu and select the ‘PRINT DAILY
LOG’ button.
The print out contains a list of the number of cycles that have been run for the
period from the last reset time. Included on the log report is the cycle type,
run number and pass or fail status.
8.9.8 Generator Blowdown (Generator Units)
For sterilizer’s fitted with Steam Generators an additional button is available –
the GENERATOR BLOW DOWN button. When pressed the following screen
will appear. From this screen the blowdown of the generator is programmed.
Enable the days by selecting the tick this will cause the thumbs-up signal to
appear thus indicating that the day has been enabled for an automatic
blowdown. Set the time you require the Steam Generator to be automatically
blown down by touching the Set Time values, then select “SAVE”.
8.9.9 Blowdown with Deep Sleep
Another new feature that has been added to the Atherton sterilizer control
system is the option to enable the blowdown when the unit has been put into
Deep Sleep:
43 of 73
UM 34 Rev 0
Atherton Sterilizer – System Administration Manual
04/02/2009
If this feature is enabled the system will automatically blowdown the unit
whenever the Deep Sleep button is pressed.
CAUTION: with this feature enabled the delay to restart the unit after returning
from Deep Sleep is a minimum of 20 minutes plus heat up time. This is the
amount of time it takes to complete blowdown, then refill the unit, before the
generator elements can be enabled. Hence if you require prompt access to
your sterilizer we suggest you disable this feature.
8.9.10 Customise Operating Screen
To customise the operating screen select the ‘CUSTOMISE OPERATING
SCREEN’ button from the Administrator Menu screen.
Using the red push buttons enable or disable display of the various items on
the screen. By disabling the display of as many items as possible the refresh
rate of the remaining items will be improved. This is of particular importance
to users who require the display of the holding time counter to appear as real
time as possible.
It is important to understand that the display is affected by the amount of data
being transmitted between the PLC controlling the sterilizer and the
touchscreen.
In no way does it affect the actual holding time
programmed into the sterilizer. The PLC is accurate to 0.01 seconds.
Hence do not be alarmed if you see the holding time counter on the
touchscreen appear to skip a second you can be 100% assured the PLC
does not ever skip a second it is purely the touchscreen display.
To allow the holding time counter to refresh more accurately disable all items
that are likely to require constant update. The following items are suggested
as likely to require constant update:
The chamber pressure – the pressure in the chamber fluctuates more
frequently than any other item.
44 of 73
UM 34 Rev 0
Atherton Sterilizer – System Administration Manual
04/02/2009
The dates and time display – the seconds counter obviously requires constant
refresh.
The elapsed time counter – having a seconds counter obviously requires
constant refresh.
8.9.11 Auto Door Operation
At the end of cycle the sterilizer can be programmed to automatically open the
door:
When enabled the system will automatically open the door rather than
displaying a screen which requests that operator open the door by pressing a
button.
8.10
START BUTTON PASSWORDS
If your sterilizer has been ordered with Cycle Start Button security, then the
Cycle Start Passwords button will appear on the Administrator Menu Screen:
Touch the Cycle Start Passwords button and enter the level 1 and level 2
passwords – DO NOT ADJUST the level 3 password that is your Administrator
password. Only level 1 and 2 apply for the Cycle Start Security access.

9 BARRIER SEAL & DOOR SECURITY CONTROL – CYBER UNITS
9.1
GENERAL OPERATION
The barrier seal and door secuirty refer to the mode of operation of the two
motorised ball valves that control the flow of steam or compressed air to
energise the gasket. Intrinsic to this is the control of the two dump solenoids
to evacuate the gaskets so as to retract them.
The system will energise the gaskets whenever the door is closed regardless
of which door has been designated as the loading or unloading end. To
ensure that the system does not disengage the gaskets from the gasket
retainer the steam/air to gasket motorised ball valves have been electrically
interlocked with the micro switch which is “made” when the door is in the
closed position. It is this micro-switch that we suggest you monitor closely
should the system not energise the gaskets when the door is apparently in the
closed position. Remember unless the system is trying to drive the door open
meaning it is evacuating the chamber after a door operation or a passed cycle
then the gaskets should at all times be energised, if this is not the case then it
is most likely that the micro switch is not making.
In order for the system to drive a door open the required gasket must first be
retracted, to do this the system must seal the chamber, start the vacuum
pump, draw a vacuum to at least -20kPa, then open the designated door’s
gasket exhaust solenoid, close that door’s gasket energise ball valve, and
then open the air to chamber solenoid, during this the operator screen
displays the following:
Once the above mentioned sequence has been successfully completed
followed by a delay for the chamber pressure to be greater than -5kPa the
system will then drive the door open.

9.1.1 System Security Levels
The sequence of operation of a barrier seal sterilizer, by very nature of the
need to preserve the integrity of the seal between the ends of the sterilizer
places strict limitations on the mode of operation of the unit. To overcome
these limitations which can impact on the efficiency of work practices for the
modern research facility the system can be programmed to operate in one of
three security modes, in this way users wishing to load and unload from the
same end, without having to operate the other end door can efficiently process
their goods in the unit. Alternatively the system can be programmed to
operate in an extreme mode whereby the strictest limitations on the operation
of the door dictate that the unit will not operate any door after a failed cycle.
By default the unit is pre-configured to operate the door sequence and
maintain the barrier seal as described in the previous section, this mode of
operation is referred to as “Hi Security” mode. The other modes of security
are; Medium and Extreme.
9.1.1.1 Changing the System Security Level
To alter the security mode navigate to the Administration Menu. This is done
from the home screen by selecting the Help Menu button, then from the Help
Menu screen select the Operator Administrator Settings button. At this point
you will be requested to log in with the Administrator password. From the
Administrator Menu screen (shown below) select the Security Level Button:
At this point you will be requested to login at a new level of user access. Level
5 has been introduced into the system the default level 5 password is: 555
(your Atherton service technician can change this).
After you have successfully logged in you will have access to the System
Security Level screen (shown below). On this screen the system security
levels are explained and the buttons on the right hand side can be used to
select the desired level of security.
47 of 73
UM 34 Rev 0
Atherton Sterilizer – System Administration Manual
04/02/2009
The skull and cross bones icon and the On/Off (red/green) indicator are used
to indicate the current system level:
This icon indicates that the system is operating in the default High Security
level.
The security levels are detailed in the following sections.
9.1.2 MEDIUM SECURITY LEVEL
In Summary:
The user has control over both doors at all times except after a failed
cycle where control is restricted to the loading end only.
In Detail:
Medium security level allows the greatest flexibility for control over the doors, it
should be used where the processing of goods often requires that the
unloading end is also the loading end. To protect the users and the institution
from potential problems arising from the incorrect opening of the unit and
removal of the contents without the processing of the goods the system alerts
the user to the operation of the doors outside of a cycle, it then also requests
that the user enter one of the user identifications, this is printed out on the
hard copy printer and the subsequent operation and user id are permanently
written to the compact flash memory card. The sequence is shown below:
The user selects the Doors icon from the home screen:
48 of 73
UM 34 Rev 0
Atherton Sterilizer – System Administration Manual
04/02/2009
This will display the warning screen informing the user that a cycle has not
been run. To continue the user must select the Doors button or to return to the
home screen simply touch the Unsterile Contents Cancel Door Operation
button.
By selecting the Doors button the user will be forced to enter a valid Operator
User ID as setup in the Administrator Menu:
For details on Operator Name and ID’s refer to the section: SETTING NEW
OPERATOR NAME & I.D. CODES on page:29 in the Administrator Settings
sections of this Manual.
49 of 73
UM 34 Rev 0
Atherton Sterilizer – System Administration Manual
04/02/2009
Follow the on screen instructions. If the user identification is accepted the
system will advance to the door control screen:
At this stage the user is free to operate either door as required. Once the
required operation is initiated the system will printout the operation along with
the users id, the date and the time, a sample printout is shown below:
9.1.3 HIGH SECURITY LEVEL
In Summary:
The user is only able to access control of the loading end door. After
a passed cycle the user can only close the unloading end door and thereafter
50 of 73
UM 34 Rev 0
Atherton Sterilizer – System Administration Manual
04/02/2009
open or close the loading end door. If the cycle fails the user only has control
of the loading end door.
In Detail:
High security level restricts the control over the doors outside of a cycle to the
loading end only. In this way the unit maintains strict access to the unloading
end only after a passed cycle. The sequence for operating for the door when
a cycle has not been run is shown below:
The user selects the Doors icon from the home screen:
The door operation screen is displayed with only the loading end door icon
visible:
Note: We have shown here screen which confirms the the configuration for
this unit to confirm this unit was configured to unload from the Other end:
51 of 73
UM 34 Rev 0
Atherton Sterilizer – System Administration Manual
04/02/2009
In this example we can see that the system has been configured to unload at
the other end door, hence the visible door icon is “this” door’s. The user can
then initiate the required sequence by selecting the Operate This Door Button.
9.1.4 EXTREME SECURITY LEVEL
In Summary:
The user is only allowed access to control the loading end door. After a
passed cycle the user can only close the unloading end door and
thereafter open or close the loading end door. If the cycle fails the user must
enter either repeat the cycle or start a new cycle. There is no access to door
operation after a failed cycle.
In Detail:
Outside of a cycle Extreme Security level has the identical door sequence as
High, please refer to the previous section.
9.2
PASSED CYCLE DOOR SEQUENCE – MEDIUM SECURITY LEVEL
After a passed cycle if the system is operating in medium security mode the
user has access to open either door:
52 of 73
UM 34 Rev 0
Atherton Sterilizer – System Administration Manual
04/02/2009
Note: If the system has Auto-Door Operation enabled the unit will
automatically open the unloading end door.
9.3
PASSED CYCLE DOOR SEQUENCE – HIGH & EXTREME SECURITY LEVEL
After a passed cycle if the system is set to either High or Extreme security
level the user only has access to open the unloading end door:
For the above example the system had been set with the Other end door as
the unloading end.
Note: If the system has Auto-Door Operation enabled the unit will
automatically open the unloading end door.
9.4
FAILED CYCLE DOOR SEQUENCE – MEDIUM & HIGH SECURITY LEVEL
If the cycle fails and the unit is set in either Medium or High security mode
then the user is restricted to only accessing the loading end door control:
53 of 73
UM 34 Rev 0
Atherton Sterilizer – System Administration Manual
04/02/2009
For the above example the system had been set with the Other end door as
the unloading end.
Note: Auto-Door Operation is disabled in the event of a failed cycle.
9.5
FAILED CYCLE DOOR SEQUENCE – EXTREME SECURITY LEVEL
If the cycle fails and the unit is set in extreme security mode then the user is
required to initiate another cycle before the door operation will be accessible:
In the event that the contents of the sterilizer could become unstable or
damaged through exposure to another cycle it is possible to override the
Extreme Security mode – however Atherton suggest only proceeding with
extreme caution. Refer to the next section:
9.5.1 Changing the System Security Level After a Failed Cycle
CHANGING THE SYSTEM SECURITY LEVEL AFTER A FAILED CYCLE
SHOULD ONLY BE UNDERTAKEN BY AN ADMINISTRATOR AND ONLY IN
THE PRESENCE OF AT LEAST ONE WITNESS. THE ENTIRE PROCESS
SHOULD BE MANUALLY RECORDED WITH EACH PARTY WITNESSING
THE PROCESS AND SIGNING OFF ON THE PROCEDURE.
In the event that the contents of the sterilizer must be removed after a failed
cycle it is possible to change the system security level by selecting the
Security Level Button at the bottom of the displayed screen. After the user
has logged on at level 5 select the button again and the Change Security
Level Screen will be displayed. If the security level is changed from Extreme
to either of Medium or High the bottom Return To Cycles button will change to

11 USEFUL GUIDELINES
11.1
PREPARING THE LOAD
Use freshly laundered 140 thread count muslin (or material that can be shown
to be equivalent to 140 thread count muslin)
Limit the size and density of each pack. This ensures complete steam
permeation and provides a liberal safety margin. Pack sizes should be as
follows:
LINEN: Maximum Size:
Maximum Weight:
250 x 250 x 350mm
5.5 Kg.
No pack should have a density greater than 115 Kg/Cu.M
METAL WARE:
Maximum Weight:
Maximum Number of Instruments:
99
6.8 Kg
Do not stack or nest utensils unless, they are separated by an absorbent
material
Use two double thickness 140 thread count muslin sheets as wrapping
material for surgical supplies. This provides protection after sterilization for
the goods.
MUSLIN OF 140 THREAD COUNT IS THE PRESENT STANDARD FOR
STEAM STERILIZATION. THE MANUFACTURER OF OTHER MATERIAL
SHOULD SHOW DATA THAT INDICATES HIS PRODUCT IS EQUIVALENT
TO THE MUSLIN PROFILE IN STEAM STERILIZATION, DRYING, AND
STERILITY MAINTENANCE.
11.2
LOADING THE STERILIZER
Place all textile packs on edge and arrange the load in the chamber to allow
only minimal resistance of steam passage through the load.
Place jars, canisters and all other non-porous containers of dry material on
sides with covers removed or ajar. This permits rapid displacement of air and
quick contact of steam with all surfaces of containers and contents. Drying is
also facilitated.
Place utensils and treatment trays on edge so that they will be sterilized and
dried properly.
Place instrument sets in a tray that has a MESH BOTTOM. Place FLAT in the
chamber for sterilization.
In mixed loads, combining fabrics and hard goods, place the hard goods on
the lower shelf of the loading car. This prevents wetting of muslin packs from
condensate dripping from the hard goods.
DO NOT OVERLOAD THE STERILIZER.
Avoid contact of the load with the walls of the sterilizer.
STERILIZE LIQUIDS SEPARATELY FROM OTHER GOODS
62 of 73
UM 34 Rev 0
Atherton Sterilizer – System Administration Manual
04/02/2009
Every sterilizer should be checked at least weekly with a biological spore
indicator (spore strip) to confirm adequate performance. Contact your
ATHERTON office for details.
Care must be taken to avoid contact between bare skin and the sterilizer
chamber and door surfaces. Appropriate protective clothing should be worn.
Insulated gloves are recommended as a minimum. Failure to do so may result
in severe burns.
Ensure your hands and fingers are not near the top of the chamber when
closing the door. Failure to do so may result in injury.
11.3
UNLOADING THE STERILIZER
Care must be taken to avoid contact between bare skin and sterilizer
chamber, door, carriage, basket and load. Appropriate protective clothing
should be worn. Insulated gloves are recommended as a minimum. Failure to
do so may result in severe burns.
To remove the load, slide the tray forward until the stop is reached, or roll the
carriage onto the transfer trolley
The Sliding tray assembly, or carriage rails are removable for cleaning. Please
refer to the maintenance section for details
Personnel must not enter the chamber unless they are carrying of
maintenance to the sterilizer. Refer to the maintenance section for details.

12 ROUTINE MAINTENANCE
THE FOLLOWING PROCEDURES SHOULD BE PERFORMED AT
REGULAR INTERVALS, AS INDICATED, AND IS THE RECOMMENDED
MINIMUM. IF STERILIZER USAGE IS INCREASED, THE
MAINTENANCE PROGRAMME SHOULD INCREASE.
When entry to the chamber is required or prior to any maintenance the
following must be carried out:
Turn isolating valve on steam supply to off position.
Turn power switch off, located behind the hinged front cover.
Turn off the power at the supply power switch then remove the plug from the
switch. Confirm power to the control system has been isolated.
1. Allow the sterilizer and loading equipment to cool.

CLEANING
1. Chamber, Door, Screen and Loading Equipment (Weekly)
Never use a wire brush or steelwool on the chamber, door or loading
equipment. The chamber must be cold prior to cleaning. Failure to
clean the chamber regularly & properly, may void your warranty.
Remove the chamber drain strainer and flush under running water.
The Ha-Ra system is recommended for cleaning of the Sterilizer. Contact
your local Atherton Office for details.
Ultra Blue Glove
Scrubs and loosens any residue and build up. To use immerse the glove in
cold water and wring out the excess water.
White Short Glove
This is the follow on glove that will collect the excess water and the dirt that
has been loosened by the Ultra Blue glove.
This system can be used on almost any surface in the CSSD.
The door gasket should be removed and cleaned as required, depending on
the quality of the steam.
The screen can be cleaned by gently wiping with a damp cloth.
The loading equipment can also be cleaned with Ha-Ra products
12.2
DOOR (Weekly)
Check that the door leading edge operates correctly.
Using the door function on the touch screen, close the door and when the
door first starts to close, touch the leading edge with an object to ensure the
door stops travelling.
If the door does not stop travelling, immediately shut down the unit
and contact your local Atherton Office. The unit must not be used
until the leading edge operates correctly. Failure to follow these
instructions could result in serious injury.

12.3
GASKET REMOVAL
Care must be taken to ensure the gasket is not damaged. Screw
drivers etc. are not recommended for this procedure. Remove the
gasket and clean all surfaces of the gasket and gasket retainer. It is
important that all foreign matter is removed to ensure proper
performance of the gasket.
To replace the gasket, start by locating the 4 corners. Ensure the moulded
corner of the gasket is evenly positioned around the corner.
To ensure distortion free installation, insert the centre section between the
corners next, then insert the remaining gasket to complete the installation.
No tools are required to replace the gasket. The gasket is to be
replaced by hand only. If the sterilizer chamber is hot, protective gloves
should be worn.
After the entire gasket has been inserted, ensure none of the gasket
protrudes past the front of the gasket retainer. Failure to do so may
result in damage to the gasket.
12.4

66 of 73
UM 34 Rev 0
Atherton Sterilizer – System Administration Manual
04/02/2009
WARNING: The replacement of the filter cartridges is a procedure that only
should be performed by personnel with the appropriate training. Do not open the
filter housings without performing the following procedure. Failure to do so may
expose the persons to harmful bacteria.
NOTE: To replace the filter cartridge, the following is to be read in
conjunction with the piping diagram in section 11.1
Before replacing the filter cartridges, the lines must be sterilized to ensure safety.
Ensure that the following manual control valves are in the indicated positions:
(The valve handle across the pipe is the closed position and the valve handle along
the pipe is the open position)
Control Valve 1: Open
Control Valve 2: Closed
Control Valve 3: Closed
To manually sterilize the filters, close valve no. [1] then open valve no. [3]. This will
allow steam to enter the filter assembly which will be indicated by a rise in pressure
and temperature on the gauges attached to the filter. Allow the required
temperature to be maintained for the required time to ensure a sterilized
environment within the filter assembly. When the sterilizing period is over, close
valve no. [3] then open valve no. [2] this will relieve the steam pressure within the
filter assembly.
WARNING: Ensure the pressure gauge reaches ZERO before opening
the filter. Protective gloves should be worn, as the filter housings will be hot.
Failure to do so may cause injury
The filter housings can now be opened and the cartridges replaced.
After the filter housings have been resealed, close valve no. [2], then open valve
no. [1]. Check all joints for leaks.
The sterilizer is now ready for normal operation.
