WIRING
The multivoltage ballast is self-adjusting and operates with voltages from 120 - 240 VAC. This unit must
cycle with the furnace blower. Install provided 120 VAC power cord and plug the unit into a 120 VAC outlet which
is interlocked with the furnace blower. If a 120 VAC EAC terminal is available, supply power to the outlet 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. After installing, verify voltage is operating between
120 - 240 VAC with the air handler operating. An optional 240 VAC power cord is available, Part #PC-240,
for 240 VAC installations.
SETTING THE ACTIVATED OXYGEN OUTPUT LEVEL
• The air purification 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 unit. Start with the setting in the normal range. Decrease the setting if an activated oxygen
odor is detectible. If 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 porcelain caps or use a soft cloth. If you accidentally touch a lamp, clean it using a
soft cloth dampened with rubbing alcohol.
CLEANING THE LAMPS -
Recommended interval: 12 months (Follow the procedure below)
Replacement lamps are available through your HVAC contractor.
REPLACING THE LAMPS -
Recommended interval: 24 months.
(Follow procedure below excluding #6.)
1. Unplug the power cord from the outlet, or disconnect power to the unit.
2. Remove the cover from the unit by removing the top and bottom retaining nuts using a 11/32
size nut driver. Do not remove the Oxidation Control knob.
(It helps to rotate the control knob to the center position before removing cover.)
3. Unplug the lamp from the lamp connector.
4. Remove lamp holder using a 11/32 size nut driver
(Figure A).
5. Remove the lamp by grasping the porcelain cap and extract carefully.
6. Using a soft cloth moistened with rubbing alcohol, wipe down each lamp. If there is a large build-up
of dust particles, you may wish to use a can of air first. Always handle lamps by end caps.
7. Slide one lamp back into lamp opening. Reinstall lamp holder.
8. Plug lamp into the lamp connector.
9. Replace cover and align the oxidation control knob with the adjustment linkage by gently turning
the knob until linkage clicks into place. Secure cover using the two retaining nuts.
10. Plug power cord back into outlet, or restore power to unit.
