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 and intended for the treatment of air extracted from the exhaust ducts of new
or existing commercial kitchens and building ventilation systems that exhaust to the outdoors. The completed
installation must 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 per-
sonnel, 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.
If damage has occurred during shipping, notify the freight carrier at once so that a claim can be filed with the carrier.
This equipment is heavy! See product specifications for rated weight. Always exercise extreme caution
when mounting or dismounting The Generator to assure it cannot be dropped. Use only approved work
platforms to access The Generator. Never stand on cooking equipment as falls can result in serious inju-
ries. Wear industry-prescribed work clothing, gloves and eye protection while mounting, dismounting or
servicing The Generator.
Electrical Shock Hazard! Disconnect power before servicing. Replace all parts and panels before operating.
Failure to do so can result in electrical shock, burns or death.
This unit emits low levels of ozone into the exhaust duct. If improperly used by unqualified personnel
extended exposure to ozone can result in irritation to eyes, skin and lungs. Always observe industry guide-
lines and safety precautions when working with equipment that generates ozone.

2. PLANNING YOUR INSTALLATION
Selecting the Correct AirMaid
Choose the AirMaid model from the following table based upon the total duct airflow for the application. If the duct has
several branches, equip each branch with the correctly sized model for its airflow. In this way we maintain a consistent
concentration of ozone (typically from 0.5 to 1.0 ppm) throughout all sections of the duct system. For larger airflows,
simply install several units in parallel. For restaurants with a higher than average grease or odor discharge, please consult
with your nearest AirMaid sales representative for recommendations for your specific application.

Inlet Air Supply (Bleed Air): Adjust to the "Target Bleed Airflow" when able
Filtered Air. The air supplied and bled through the AirMaid generator is the“fuel“ to create its ozone and must be filtered.
To minimize equipment maintenance, use an air source with the least pollutants. Inlet air is preferred taken from a filtered
central ventilation or MUA supply. If this is not possible, then a filter box satisfying at least class MERV5/EU3 shall be in-
stalled. Filter box inlet air can be taken from above an inner ceiling, from an adjoining space, or from the outdoors with
precautions taken to prevent the entry of moisture. If taken from the outdoors, never position the inlet in the vicinity of the
discharge from any ventilation system which commonly contain moisture and pollutants. If air must be taken from inside a
kitchen space, please position the intake the farthest distance possible from preparation or cooking areas. The temperature
of the inlet air shall never exceed 104°F.
Bleed Airflow. With the extraction fan running the airflow through each inlet pipe must always fall within the specification:
45–85 cfm per inlet pipe (Models 10000V and 20000V), 30–50 cfm (Models 2000V and 5000V).
When used in conjunction with VAV/VSD systems, if the total Bleed Airflow through the AirMaid generator drops below
the minimum specification at the lowest extraction fan speed then power to AirMaid must then be cut off.
Static Pressure: -0.08 inH2O to -40 inH2O
With the extraction fan running the Static Pressure inside the generator, when measured at the Pressure Check Point
(locations marked in RED), must always fall within the specification: -0.08 inH2O to -40 inH2O. This is necessary for
correct and reliable operation of the internal Pressure Safety Switch.
When used in conjunction with VAV/VSD systems, the Static Pressure must fall within specifications even at the lowest
extraction fan speed or the power to AirMaid must then be cut off.

2-Second Minimum Dwell Time for Odor Reduction
Ozone is an effective oxidant for reducing cooking odor within grease ducts of commercial kitchens. Please note that
smoke and smoke odor resulting from the grilling or searing of foodstuffs at high temperatures cannot be reduced by
ozone oxidation.
To obtain good odor reduction results with AirMaid it is important that the ozone have enough time to react with the
odor particles in the duct airstream. We call this “reaction time” or “dwell time” and is measured from the point where
the ozone gas is mixed in with the exhaust airstream ahead of the hood connection. With multiple hoods in the duct-
work, this is instead measured from the hood closest to the point of exhaust.
With this in mind we recommend a minimum dwell time of 2 seconds to obtain “good” results for the reduction of
cooking odor. However, please keep in mind that a longer dwell time will often provide even better results.
Clean the Exhaust Ducts
When AirMaid is retrofit into existing exhaust systems, the exhaust ducts must be swept clean of grease and soot at the
time of installation. This is required to achieve the desired results from the ozone cleaning.
Educate the Chimney Sweep
AirMaid is an electrical device, and as such must be protected from exposure to water, chemicals and duct waste when
exhaust ducts are cleaned. Damage due to external influences such as these is not covered under the product warranty.
It is therefore highly recommended that the duct cleaning company be informed about the AirMaid installation so care
is taken not to expose the duct connection such materials.

Important note regarding code-compliant installation
Installation requirements can vary widely between jurisdictions, or change over time. The project engineer and
installing contractor are responsible to ensure an installation complies with all local, state and national building, electric
and fire safety codes. The diagrams shown below are sample documents available to assist an engineer or architect
in designing a code-compliant installation. Contact the manufacturer or your local AirMaid representative for sample
detail recommended for your area.
Note: As shown below, in grease exhaust applications it is common a stainless steel fire damper is installed in the
connection appendage between the generator and main exhaust duct. Due to the potential for corrosion in this small
section of duct, be sure to add regular inspections/replacement of any non-stainless components such as fusible links or
sensors accompanying it (twice/year recommended) to the regular maintenance schedule for the facility.

Instead, on models with multiple pipes you may manifold together the supply and discharge pipes to single connections
as long as the resulting installation complies with the product specification for bleed air through the generator. Use
large-radius bends to avoid pressure loss.
Multiple Connections Unnecessary
At times there are misconceptions regarding our sample installation detail available as shown on the previous page, as
it only shows a“general case” side view of an AirMaid generator. Since certain models of AirMaid have multiple pipes,
sometimes an engineer or contractor has unnecessarily drawn/constructed multiple inlet and outlet connections to
the supply air and main exhaust duct:

As long as you have sufficient static pressure to obtain the correct bleed airflow through the generator, then multiple
connections to the supply and exhaust ducts like shown above is unnecessary.
Access Requirements
Routine maintenance and service of all models is performed through the bottom service hatch. An internally-hinged
electronics assembly allows electronic component access from the bottom as well. The entire underside of the genera-
tor must therefore always have free access to the service technician. Nearby ceiling tiles shall be removable to facilitate
service access. Please design your installation with sufficient clearance on all sides (minimum 4") to allow for the easy
removal of the entire AirMaid assembly, if there is insufficient space for on-the-spot repair by the technician.
Always use a safe, approved work platform while servicing the generator.

Construction Materials
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 304. Note: In grease exhaust applications it is common a
stainless steel fire damper is installed in the connection appendage between the generator and main exhaust duct.
Due to the potential for corrosion in this small section of duct, be sure to add regular inspections/replacement of any
non-stainless components such as fusible links or sensors accompanying it (twice/year recommended) to the regular
maintenance schedule for the facility.
Hanging the Generator
The ozone outlet pipe 6 may have a maximum length of 15 ft. Its preferred diameter is 5 in. with a minimum diameter
of 3 in. 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. threaded rods and anchor these with nuts on each
side of the respective bracket.
2. Fasten the outlet pipe 6 between the ozone generator 7 and the eventual connecting point to the exhaust duct.
3. Connect the inlet pipe 8 and IRIS air damper 10 to the ozone generator 7 , or use a lter box 9 with a MERV5/
EU3 lter according to the pictures below.
Make sure that all connections are properly fastened and sealed.

Note that the direction of the airflow must correspond to the arrows on the generator and the pictures below.
Filtered air is required. On models with multiple pipes, you may manifold together supply and discharge pipes to single
connections as long as the resulting installation complies with the product specification for bleed air through the
generator. Remember to add filter inspection/replacement to the maintenance schedule. With central air installations,
IRIS dampers are usually necessary for balancing purposes.

External Relay Connection
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.
Important Note!
If the electrical cables are removed during
installation, ensure the mains feed is properly
reconnected to the “IN” L/N terminals.
First: Please read section 3,“Sample Installations”for information regarding code-compliant installation.
Alarm Panel Mounting
Remove the four screws that fasten the AirMaid alarm panel to its 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 visible to the staff 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.
Electrical Connection
The installation must be performed by an authorized electrician and follow national standards and regulations. The
fan interlock displayed on the diagram below is mandatory. The purpose of the fan interlock is to shut off the main
power to the generator when the exhaust fan is turned off. An all-pole safety disconnect switch with a break length
of at least 3 mm must be installed and labeled “OZONE GENERATOR MANUAL SHUTDOWN” next to the Alarm
Panel, which shall be positioned at eye level and visible to staff. The electrical requirements for the ozone
generator are 120V AC and 60 Hz. Every generator must be connected to its own main breaker/fuse.
