WARNINGS AND SAFETY CONSIDERATIONS
General
. This installation and service guide contains important instructions and safety information for the AirMaid®
Ozone Generator (hereafter referred to as ”The Generator”). Read this guide fully before attempting to install,
operate, or perform maintenance on The Generator.
. The Generator is for commercial use only for the treatment of air extracted from the exhaust ducts of commercial kitchens and office buildings. It is designed for installation into new or existing ventilation systems that
properly exhaust to the outdoors and meet all local, state and national building, electric and fire safety codes.
. A typical installation into a commercial kitchen exhaust duct is described. Other applications for treating
extraction air may also be possible, but only for air which is released into the outside environment and never
into working or living spaces. In all cases, the specific requirements according to this guide must be fulfilled.
. The device may not be used by children or by persons with diminished physical, sensory or mental capacity
or lack of experience and knowledge unless supervised or having received instruction. Supervise children to
ensure that they do not play with the device.
. Always disconnect the electric power source from The Generator before performing any service or maintenance.
. The Generator, alarm panel and connections to inlet air and extraction ducts must be installed by qualified
personnel, in compliance with all manufacturer instructions as well as local, state and national building,
electric and fire safety codes.
Troubleshooting & Requesting Service
In the event of operational difficulties with The Generator please contact your distributor or Interzon Technical Support.
Repairs must only be performed by Interzon-trained and authorized service personnel unless prior written
consent has been given. Only original repair parts provided by the manufacturer may be used when servicing
The Generator.

Study the examples for installation below. Choose the most appropriate for your specific case. If inlet air for the generator cannot be taken from the central ventilation, then a filter box satisfying at least class ASHRAE EU3 shall be installed
as shown. The inlet air can then either be taken from above the false ceiling or from the outdoors with precautions taken
to prevent the entry of moisture or mist. Please do not take air from directly inside
the12"

quency of filter changes, use an air source with the least pollutants. The temperature of the inlet air shall never exceed
NFPA 96
104°F (40 °C).

Regarding odor reduction, AirMaid® is very effective provided there is at least 2 seconds of dwell time (sometimes
referred to as “reaction time”) for the ozone to react with the exhaust gases within the duct. This is a very important
consideration and must be taken into account while planning the exhaust ventilation for your facility.

3 INSTALLATION GUIDELINES
All ventilation components between the outlet of the ozone generator to and including the connection to the main exhaust duct must meet stainless steel specification AISI 316. The length of the ozone outlet tube 6 may have a maximum
length of 15 ft. (5 m). Its preferred diameter is 5 in. (125 mm) with a minimum diameter of 3 in. (80 mm). Make sure that
your installation does not block any inspection hatches or other equipment in the facility.
1. Hang the ozone generator. 7
The ozone generator must always be suspended horizontally by its brackets with the service hatch facing downward. Never screw or drill through the generator. Hang using 5/16 in. (M8) threaded rods and anchor these with
nuts on each side of the respective bracket. Note that it is required to retain at least 4 in. (10 cm) of free airspace on
all sides of the generator, in addition to providing easy access to the lower service hatch for its routine maintenance.
Whenever possible, also allow sufficient airspace around and above the generator to ensure easy access to its top
electronics cover, or alternatively for the easy removal of the generator, should service be necessary.

6 SERVICE AND MAINTENANCE
The initial 3-month check-up is both required and important! The check-up procedure should include an inspection
and cleaning of the cells, as well as confirming that the pressure inside and airflow specifications are still correct.
After the first check-up you decide if maintenance is required once per year or more often. Always wear hand and eye
protection when servicing the generator.
If any work needs to be
performed in the kitchen
extraction ducts, the power
to the ozone generator
must be disconnected.
Switch OFF the main power to the ozone generator and remove the service hatch under the generator.
Note: AirMaid® Models 2000V and 5000V have
one set of ozone cells to clean; the 10000V has
two sets; and the 20000V has four sets.
Make sure that the glass electrodes of the ozone cells are not damaged or cracked.
A proper ozone cell should be clean and free from any mechanical damage according to the picture to the right above.
Wet a soft, durable cleaning cloth with your alcohol-based cleaning spirit.
Never spray directly onto the ozone cell!
Caution! The glass tubes are fragile. Use only your hands and never any
sort of tool to scrape or clean the ozone cell.
First clean the surfaces of the glass electrodes and then around the base
of the cell.
Using your fabric like dental floss, gently clean between the electrodes
with a gentle sliding movement.
Finally, wipe clean the inside of the chassis.
Replace the service hatch and switch ON the main power switch on the generator. Make sure the generator has started
by checking the alarm panel – the green lamp should now glow. If the red lamp flashes then see “TROUBLESHOOTING”.
If a filter box is used, clean or replace the filter as needed to assure proper airflow through the generator.

Facts about Ozone
Ozone is a colorless gas with a pungent smell that can often be detected by any person at a concentration of 0,02ppm
(0,4mg/m3). The smell of ozone is similar to chlorine like in a swimming baths.
Local protection legislations must be followed when using ozone. For example, in Sweden the Swedish Work Environment
Authority issues the following hygienic limits for ozone:
•
0,1ppm (during a working day, 8 hours)
•
0,3ppm (during 15 minutes)
At acute exposure ozone can cause following injuries:
•
On skin:
Irritation and burning feeling
•
In eyes:
Hard irritation, burn injuries and reduced vision
•
In lungs: Irritated effect on respiratory organs and breathing problems
Always take corrective action and safety precautions if ozone is detected in an indoor environment.
