INSTALLATION:
• Do not locate the unit within 20” of plastic material that will be directly exposed to the UV light,
such as wiring, return-side humidifier or certain types of air filters. Check with the filter manufacturer
to see if their material is UV resistant. ver time, UV light may degrade plastic.
• Do not touch the glass portion of the lamps with bare hands because oils from the hands can cause
“hot spots” which reduce lamp life. Handle either by the porcelain caps or use a soft cloth. If you
accidentally touch a lamp, wipe it off, using a soft cloth dampened with rubbing alcohol.
INSTALLING THE GERMICIDAL UNIT
1. Using the lamp mount as a template, draw the hole pattern on the air duct in a suitable location.
2. Using a 1 1/4 inch Vari Bit, make two holes side by side. Clean off excess metal between the
two holes with tin snips.
3. Peel off the adhesive backing of the gasket on backside of mounting plate.
4. Center mounting plate on hole.
5. Use four self tapping screws provided to secure mounting plate on the air duct.
6. Find a suitable location to mount the ballast making sure supply cord to ballast will reach 120 to 240
volt power supply. Mount the ballast using four self-tapping sheet metal screws provided.
7.
Unplug mid cord connector by pressing the lock release (marked “PRESS” on the connector.)
Route the cord to the lamp mount area. (See Photo B)
8. Taking care not to touch the glass, hold the lamp by the plastic end and insert fully into the base plate.
9. Insert the water resistant lamp socket over the plastic lamp end fitting over the mountng studs,
secure using the two thumb nuts and reconnect the mid cord connector. (Photo A & B)
10. Adhere included UV Warning La el onto ductwork within six inches of each UV lamp..
WIRING/FUSE
The multivoltage ballast is self-adjusting and operates with voltages from 120 - 240 VAC. For 120V wiring
install a 5 amp inline fuse to L1. Connect the black wire to L1, white wire to neutral, green wire to ground. Be
sure power cord is secured with the included strain relief connector.
For hard wiring to 240V systems install
5 amp inline fuses to both legs of power. Then connect the black wire to L1, white wire to L2, green
wire to ground.
Be sure power cord is secured with the strain relief connector.
It is not necessary to cycle the germicidal air purifier with the furnace blower. You may allow unit to run
continuously or have it interlocked with the furnace blower. If a 120 VAC EAC terminal is available, supply
power to the unit from the EAC terminal. Connect in accordance with local wiring codes. If there is no EAC
terminal, interlock the UV unit with the furnace blower using an appropriate alternate. Wire the unit in
accordance with local wiring codes. After installing, verify voltage is operating between 120 - 240 VAC
with air handler operating.

MAINTENANCE
This maintenance schedule is only a guideline, determined by average conditions. Actual conditions
will dictate the frequency of cleaning and/or replacement of lamps. Do not touch the glass portion of the
lamp with bare hands because oils from the hands can cause “hot spots” which reduce lamp life.
Handle either by the socket end or use a soft cloth. If you accidentally touch a lamp, clean it using a
soft cloth dampened with rubbing alcohol.
CLEANING THE LAMP - Recommended interval: 12 months
1. Disconnect power to the unit. Unplug mid cord connector before removing lamp.
2.
Remove two thumb nuts from lamp mount then holding the lamp socket pull away from lamp mount.
3. Using a soft cloth moistened with rubbing alcohol, wipe down the lamp. If there is a large build-up
of dust particles, you may wish to use a can of air first. Always handle lamp by the end socket.
4.
Carefully slide lamp into duct through lamp mount reinstalling thumb nuts until is fits securely.
5. Reconnect mid cor connector and restore power to the unit.
REPLACING THE LAMP - Recommended interval: 24 months
Replacement lamps are available through your HVAC contractor.
Follow above procedure except #4 where you replace the lamp instead of cleaning it. (Note: standard
off-the-shelf lamps are not compatible with this unit. Use of improper lamps will void warranty.)
TROUBLESHOOTING
