Installation & Maintenance Instructions
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 rubbing alcohol. The
lamp is fragile and proper care must be taken when removing from
packaging.

INSTALLATION: Living space, 1,200 square feet minimum.
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 lamp within 20” of plastic material that will be directly 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 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

CORRECT WIRING FOR SINGLE LAMP OPERATION. CORRECT WIRING FOR DUAL LAMP OPERATION.
WIRING/FUSE
With the oxidizing unit installed, the unit must cycle with the furnace blower. Wire unit to an EAC
terminal or current-sensing relay to cycle the unit with the system fan. If the oxidizing unit is not installed, you
may allow unit to run continuously. The multi-voltage 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 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.

SETTING THE ACTIVATED OXYGEN OUTPUT LEVEL
• The air purication process occurs only while air is circulating through the HVAC system.
• 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.
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. Unplug mid-cord connector by pressing the lock release (marked “PRESS” on the connector.) 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
