UNPACKING THE UNIT
The optional oxidizing unit is shipped with the 5” lamp installed.
The germicidal lamp is placed in a box with protective packaging.
When handling lamps take care to not touch the glass portion of
the lamp with bare hands. Oils from the hands can cause “hot
spots” which reduce lamp life. Handle by the end caps or use
a soft cloth. If you accidentally touch a lamp, clean it using the
included alcohol cleaning pad or a soft cloth dampened with rub-
bing alcohol. The lamp is fragile and proper care must be taken
when removing from packaging.

INSTALLATION:
If there is a device that creates ozone in the space such as an ionizing air cleaner, it is recommended the oxidizing unit
not be used in this application. Use one of our germicidal only models instead. Homes with multiple air handlers:
install this unit on the main level air handler and a germicidal only model on the other air handler(s).
• Do not locate the germicidal lamps in direct sight of plastic material that will be exposed to the UV light, such as
wiring, return-side humidier or certain types of air lters. Check with the lter manufacturer to see if their
material is UV resistant. Over time, UV light may degrade plastic.
• Do not install the UVC lamps where there is a straight line of sight of the lamps through a vent.
When choosing a location to mount the lamps, make certain no UV light is visible to the consumer.
• 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 side only when installing with oxidation unit.)
1. Unplug mid-cord connector (s) 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.
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 tting 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. (see photo B)
9. Adhere included UV Warning Label onto ductwork within six inches of UV lamp.
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 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, clean it using a soft cloth dampened with rubbing alcohol.
CLEANING THE GERMICIDAL LAMP - Recommended interval: 12 months
1. Disconnect power to the unit.
2. Unplug mid-cord connector by pressing the lock release (marked “PRESS” on the connector.)
Remove two thumb nuts holding moisture resistant lamp socket to mounting plate and carefully remove the
lamp socket with lamp from the mounting plate.
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 rst. Do not touch the glass portion of the lamp with bare hands.
4. Carefully slide the moisture lamp socket with lamp through the mounting plate into duct tting over the
mounting studs and secure using the two thumb nuts and reconnect the mid-cord connector.
5. Supply power to the unit.
CLEANING THE OXIDATION UNIT LAMP - Recommended interval: 12 months
1. Disconnect power to the unit.
2. Remove the two 11/32” keps nuts and remove cover. Unplug the lamp connector from the end of the lamp
then remove the lamp holder using a 11/32 size nut driver. Remove the lamp by grasping the end cap and
extract carefully.
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 rst. Do not touch the glass portion of the lamp with bare hands.
4. Slide the lamp back into the lamp opening. Reinstall lamp holder and plug the lamp connector to the end
of the lamp.
5. Replace the cover and align the odor control knob with adjustment linkage by gently turning the knob
until linkage clicks into place. Secure cover using the two retaining nuts.
REPLACING THE LAMP - Recommended interval: 24 months
Replacement lamps are available through your HVAC contractor.
Follow above procedure except #3 where you replace the lamp instead of cleaning it.
Please see next page for a list of replacement lamps available.
(Note: standard off-the-shelf lamps are not compatible with this unit. Use of improper lamps will void warranty.)

• The oxidizing level can be easily adjusted as needed using the “Oxidation Odor Control” knob on the front of the
unit. Start with the setting in the normal range. Decrease the setting if an activated oxygen odor is detectable.
If household odors are noticeable after 24 hours, increase the setting.

CORRECT WIRING FOR SINGLE LAMP OPERATION. CORRECT WIRING FOR DUAL LAMP OPERATION.
WIRING/FUSE
It is recommended you interlock with the system blower or install a blower door safety switch so the
unit powers off when the system is serviced. With the oxidizing unit installed, the unit must cycle with the
furnace blower. Connect in accordance with local wiring codes. The multi-voltage ballast is self-adjusting and
operates with voltages from 120 - 240 VAC. For 120V wiring connect the black wire to L1, or EAC terminal,
white wire to neutral, green wire to ground.
For 240V wiring install 5 amp in-line fuses 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. Wire the unit in accordance with
local wiring codes. After installing, verify voltage is operating between 120 - 240 VAC with air handler operating.
