INSTALLATION:
• Do not locate the germicidal lamp 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. Over 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 end caps or use a soft cloth. If you accidentally touch a lamp, wipe it
off, using the included alcohol cleaning pad or a soft cloth dampened with rubbing alcohol.
INSTALLING THE GERMICIDAL UNIT
MOUNTING GERMICIDAL LAMP AND POWER SUPPLY (supply or return side plenum)
1. Unplug mid-cord connector by pressing the lock release (marked “PRESS” on the connector.) (see photo B)
Remove two thumb nuts holding moisture resistant lamp socket to mounting plate and remove from the plate.
2. Using the lamp mounting plate as a template, draw the hole pattern on the air duct in a suitable location.
3. 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. Alternately cut a 2” hole.
4. Peel off the gasket backing from lamp mounting plate and center over hole. Secure using four
self-tapping sheet metal screws provided. Repeat steps 1-4 for the second lamp.
5. Find a suitable location to mount the power supply making sure supply cord to ballast will reach 120 or
240 volt power supply. Mount the power supply using four self-tapping sheet metal screws provided.
6. Taking care not to touch the glass, hold the lamp by the end cap and insert fully into the base plate.
7. Insert the moisture resistant lamp socket over the plastic lamp end fitting over the mounting studs,
secure using the two thumb nuts. (Photo A)
8. Route cord back to the moisture resistant lamp socket and reconnect mid-cord connector. Be sure to line up
arrows on the connector. (Photo B)
9. Adhere included UV Warning Label onto ductwork within six inches of UV lamp.
WIRING/FUSE
The multivoltage ballast is self-adjusting and operates with voltages from 120 - 240 VAC. For 120V wiring
connect the black wire to L1, white wire to neutral, green wire to ground. For 240V wiring 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 included strain relief connector.
It is not necessary to cycle the germicidal air purifier with the furnace blower. You may allow the 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.
