IND-AHC-CR-12-UVC-R1-120V
Attach supply line wires to the appropriate light fixture wires as shown
in the diagram 
Secure each pair of wires according to the diagram. Utilize a junction box or
similar device and take precautionary steps for weatherproofing all
connections if installed in a location where water may come in contact with the
unit. Ensure the unit is properly grounded and that wiring is done according to
all local and national electrical/building codes.
Standard Cord Cap
This unit comes pre-wired from factory with the selected cord cap. Take
precautionary steps for weatherproofing all connections if installed in a
location where water may come in contact with the unit. All outdoor
installations and indoor installations near a wet location require the use of a
GFCI device for safety, according to the National Electrical Code®
(NEC). Ensure the unit is properly grounded.
OPERATION
Surrounding "dirty" air is drawn into the UV sanitation unit via a ventilation fan. The "dirty" air passes through the UV
sanitation chamber where it is treated with UVC light using powerful 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 the
bottom base, which is equipped with a vent and air filter, and is released into the environment. This low-maintenance air
disinfection process is continuous.
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.
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.
BULB REPLACEMENT
Warning: Do not touch bulb with bare hands. The oils in your skin will damage the lamp. Fingerprints will result in reduced performance
and significantly reduce the lifespan of the lamp unless removed with alcohol. Be sure fixture is disconnected from power source and
cooled off before servicing.
To replace a bulb in your fixture, you must first remove the light from power. Remove the cover from the fixture to reveal the bulbs. Remove
the bulb to be replaced by grabbing the ends and pressing either up or down against one of the spring loaded bulb receptacles. This will
free the other end and allow you to remove the bulb. Replace the bulb with one of the same type and rating. Install the new bulb by aligning
the 2-pin connector with the slots in the bulb receptacle at the bottom. Press the bulb down against the spring loaded receptacle to create
room at the top, and align the two top pins on the bulb with the top receptacle and release. Repeat this process for any remaining bulbs that
need to be replaced. Test the new bulbs before reinstalling the fixture's cover. After ensuring proper operation, replace the lens cover and
then connect the fixture to power, and continue use.

Ultraviolet Radiation Safety
WARNING: Do not attempt operation until you are familiar with all warnings, precautions, and procedures outlined within
this instruction 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.
