MAINTENANCE
Caution: To avoid personal injury, disconnect power to the light and allow the unit to cool down before
performing maintenance.
Warning: No user serviceable parts inside of fixture. Risk of electric shock. Removal of the lens will void
the warranty.
1. Perform visual, mechanical and electrical inspections on a regular basis. We recommend routine
checks to be made on a yearly basis. Frequency of use and environment should determine this. It is
recommended to follow an Electrical Preventive Maintenance Program as described in NFPA 70B:
Recommended practice for Electrical Equipment.
2. The lens should be cleaned periodically as needed to ensure continued photometric performance.
Clean the lens with a damp, non-abrasive, lint-free cloth. If not sufficient, use mild soap or a liquid
cleaner.
3. Inspect the cooling fins on the luminaire to ensure that they are free of any obstructions or
contamination (i.e. excessive dust build-up). Clean with a non-abrasive cloth if needed.
4. Do not operate if the lens is cracked or damaged. All fasteners should be properly seated.

MOUNTING
The IND-AHC-TRF-2X2-UVC-R1-120V is compatible with 2x2 troffer mount installations on ceilings. We offer models with
surface mount features for installations on ceilings without tiles or grids.
OPERATION
Surrounding "dirty" air is drawn into the UV purifier via filters. The "dirty" air passes through the UV sanitation chamber
where it is treated with UVC light using the three T8 fluorescent lamps. The disinfection process kills up to 99.9% of
viruses, bacteria, mold, spores and other harmful microbes. Clean sanitized air exits the chamber through a louvered
exhaust panel and is released back into the environment. This low-maintenance air disinfection process is continuous and
quiet.

Ultraviolet Radiation Safety
WARNING: Do not attempt operation until you are familiar with all warnings,precautions,and procedures outlinedwithin
thisinstruction sheet.
OPERATION PRECAUTIONS
•UV LIGHT WARNING: UV-C light can cause temporary or permanent loss of vision, and temporary acute
redness or ulceration (mild to severe sunburn) to exposed skin. To prevent exposure, do not operate the device
in any application that allows UV-C light to be visible during operation.
•UV LIGHT CAUTION: UV light may degrade plastic and rubber components after longterm exposure.
•Currently, there are no work place related rules and regulations that are set by OSHA (Occupational Safety and
Health Association) in regard to UVC environmental health and safety.
•NEVER LOOK DIRECTLY AT THE BULB OR DISINFECTING TARGET ZONE
OPERATION SAFETY
•People and animals are forbidden from being exposed to the light output of this light for extended periods of
time. Long term exposure will case damage to the eyes and skin.
•This product produces UV radiation. Anything in front of the unit will be exposed to UV radiation. Operators
positioning the light while not illuminated will not be exposed. Radiation is only emitted while the light is turned
on. Radiation will not linger in the environment when the lamps have been powered off. Safety equipment is only
required when the device is in-use.
•Wear eye protective gear when operating the equipment. Polycarbonate safety glasses at minimum are required
during all operations. Full frontal polycarbonate or UV-preventative face masks are recommended.
•Wear long sleeves and gloves when operating the equipment. Personal protective gear is required for long term
exposure.
These safety precautions will help ensure service personnel are protected from accidental exposure while maintaining
the effectiveness of UV-C to eradicate biological contaminants.
In the event of UV exposure, the following actions are recommended.
OPERATION SAFETY STRATEGIES
•Instruct service personnel to never look directly at UV-C light without adequate eye protection.
•Make it a policy to never enter areas being disinfected with UV lighting systems without powering the system
down first. Methods of powering down depends on the options of the device purchased and may include
unplugging the light source, operating the power switch to power the lamps off, or turning the system off via a
wireless remote control or wireless application.
•Place warning labels near all openings/entrances to areas being disinfected with UV lighting systems. When
possible, lock access doors to prevent unexpected guests from entering the area.
•Close blinds/curtains of areas being disinfected with UV lighting systems if available. If not available, block off
direct access to windows/doorways to prevent access to the area. If you cannot fully block off all access
(hallways with visible windows, etc) place exterior warnings in areas prior to the exposed windows (hall
pedestals, banners, posters) explaining what areas are being disinfected and to not look into the room.
•Educate non service personnel about the intended operations for UV disinfecting and what signage will be
posted. Instruct non service personnel to never look directly at UV-C light.
•Instruct service personnel to always wear personal protective gear (as outlined above) when they must operate in
an area that has UV-C exposure, for short or long term work.
•See an ophthalmologist if eye damage is suspected.
•Treat skin lesions immediately.
•For severe skin lesions, seek local medical treatment and follow their recommendations for treatment.
•Follow your organization’s incident reporting procedure. These often require documentation of the date and
time of the incident, persons involved, equipment involved and type of injury.
