This guide describes a typical installation in a commercial kitchen exhaust duct. The product can also be used
in other applications as long as the specic requirements according to the guide are fullled.
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.

2 SYSTEM OVERVIEW
You should carefully study the example installations below. Select the type of installation that works best for you and
that complies with all national standards and regulations. If a central air supply cannot be used, a lter box EU3 class or
higher is required; the air can be supplied from the ceiling space or from the outdoors. In order to reduce the frequency
of lter changes, the supply air should originate from a place containing the least possible impurities. The tempera-
ture of supply air should not exceed 40°C. AirMaid® is very eective in reducing odors provided that the reaction time
between the ozone and the exhaust air in the kitchen duct is at least 2 seconds. This reaction time is important and must
be taken into account during the planning stage.

3 INSTALLATION GUIDELINES
1. Prepare two circular holes in the kitchen duct 6 7 or in the kitchen hood 8 . The diameter of the holes depends
on the diameter of the pipe you select. The diameter of the pipe should be between Ø 80 and 125 mm.
2. Install the ozone generator. 4
The ozone generator must be installed horizontally with the suspension brackets upward and service hatch down-
ward. Use M8 threaded rods and anchor these with nuts on each side of the respective bracket. Note that the mini-
mum installation dimension for the generator is 700x500x450 mm.
AirMaid® 20000 V Exhaust-airow max 10000 m3/h (2800 l/s)
The generator must be easily accessible after installation. Never screw or drill through the generator. Always use the
brackets for suspension.
The duct connection 5 should be no more than 5m long and with a diameter of at least Ø 80 mm. The duct con-
nection must be made of stainless steel (AISI 316). Make sure that the duct does not block any inspection holes.
Note that the direction of the airow must correspond to the arrows on the generator and the picture below.
3. Fasten the outlet tube 5 between the ozone generator and the kitchen duct 6 7 (or the hood 8 ). Make sure
that the connections are properly xed and air-tight.
4. Connect the inlet tube 3 and the IRIS air damper 2 to the ozone generator 4 , or use a lter box with a EU3 lter.
When used with a central air supply, the IRIS air damper is required to achieve the proper airow and pressure.
For more information, see section “5 SYSTEM TEST”.
The exhaust ducts must be swept clean of grease and soot at the time of installation. This is required to achieve the
desired result of the ozone cleaning.

The installation must be performed by an authorised electrician and follow national standards and regulations.The in-
terlock device displayed on the diagram below is mandatory. A Typical example of the safety interlock would be to shut
down the main power to the generator when the exhaust fan is shutting down. An all-pole safety switch with a break
length of at least 3 mm must be installed as well. The electrical requirements for the ozone generator are 230V AC and
50 Hz. Each and every generator must be connected to its own 6A fuse.
Remove the four screws that fasten the AirMaid® alarm panel to it’s base. Fasten the base to the wall using devices
suitable for the wall material. In commercial kitchens place the alarm panel where it will be visable to the sta but
not to customers.
NOTE: Upon delivery the generator and alarm panel within the shipping carton are calibrated together and have
matching serial numbers. Make sure that generators are always connected to their own alarm panel.
If you desire to connect AirMaid® to an external monitoring or alarm system, you can accomplish this by connecting it to
the external alarm terminal block within the AirMaid® alarm panel.
NOTE: The maximum load is rated to 250V and 4A.
The earth ground cable is connected to the chassis screw next to the circuit board.

Measure the airow through the ozone generator and note the value here __________
Measure the pressure inside the ozone generator and note the value here __________
The values above must be entered in the supplied product registration form.
The specied airow must be 30±10 l/s and the specied pressure must be less than -20 Pa (max -10 kPa). Usually the
airow is measured over the damper while the pressure can be measured from the pressure checkpoint on the long side
of the ozone generator.
1. Ensure that the correct airow and pressure is maintained according to the specication.
2. Ensure that the electrical wiring is correctly installed.
3. Ensure that the exhaust fan is running.
4. Ensure that the grease lters are properly installed in the hoods in the kitchen.
5. Ensure that the main power switches are ON (red light must glow) at the ozone generators.
6. Ensure that the interlock is working properly.
7. Ensure that there is no leak in the tubing after the ozone generator.
8. If the ozone generator is installed with a lter box, make sure that the lter is clean.
9. If the system still does not start call the distributor or the manufacturer.

The ozone cells inside the ozone generator must be checked and if necessary cleaned at least once a year according to
the instructions below. If a separate air lter is used for the inlet air, make sure that this lter is changed at least one time
per year. After a new installation it is anyhow recommended to make an inspection already after three months. Always use
protective gloves and protective goggles.
1. Switch OFF the main power to the ozone generator.
2. Open the service hatch on the bottom of the ozone generator.
3. 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.
4. Clean the glass electrodes carefully with a soft towel together with some cleaning spirit. Never use any sharp tools
or abrasive materials for cleaning the glass electrodes.
5. Close the service hatch and switch ON the main power on the ozone generator. Make sure that the generator starts
by checking the alarm panel. If everything works the green lamp will glow. If the red lamp ashes then see –
“TROUBLESHOOTING”.
6 SERVICE AND MAINTENANCE
If any work needs to be performed
in the kitchen extraction ducts, the
power to the ozone generator must
be disconnected.

The ozone generator is supplied with a pressure and thermal switch. The pressure switch ensures that the ozone genera-
tor only starts when the required negative pressure is established. The thermal switch prevents the ozone generator from
overheating. The main switch is supplied with a thermal overload protection of 2A.

Facts about Ozone
Ozone is a colorless gas with a pungent smell that can 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. 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 eect on respiratory organs and breathing problems
Basically one should always take precautions if ozone in some way can be detected in indoor environment.
