Oxidizing UVC System
Installation & Maintenance Instructions
UNPACKING THE UNIT
Each unit is shipped with the 5” lamp installed and the germicidal lamp
placed in a box with protective packaging. Carefully remove lamp from
the tube taking 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.
The following parts are included: • MUV-403H Unit
• Germicidal Twin H Lamp (packed in lamp box)
• Four Sheet Metal Screws
• Installation & maintenance instructions
• 120 VAC Power Cord (PC-120)
• Alcohol pad for cleaning lamps

INSTALLATION: Living space, 1,200 square feet minimum.
Best results are achieved when the unit is installed where the HVAC system air temperature is most constant.
Therefore, the preferred installation is on the return side of the furnace. If return side installation is not possible,
install the unit on the supply side. Mount the MUV-403H upstream when installing in combination with a polarized
media air cleaner.
If there is a device that creates ozone in the space such as an ionizing air cleaner, it is recommended the MUV-403H
not be used in the application. For example, an MUV-401H could be substituted. Homes with multiple air handlers:
install one MUV-403H on the main level air handler and an MUV-401H or MUV7-50PS on the other air handler(s).
Do not locate the unit within 20” of plastic materials 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 some plastics and petroleum based materials.
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.
1. Cut out the shaded area of the installation template. (Please see insert.)
2. Center the template on the longitudinal axis of the plenum and attach with tape.
Trace the hole pattern for the unit and mark centers for mounting screws. (Airow direction is marked on the unit.)
3. Cut openings for the unit using a 2” hole saw or tin snips.
4. Remove the cover from the unit by removing the top and bottom retaining nuts using an 11/32 size
nut driver and set aside. Do not remove the oxidation control knob.
(For easier installation rotate control knob to the center position before removing cover.)
5. Attach the unit to the air duct using the four self tapping sheet metal screws provided.
6. Remove the germicidal lamp holder using a 11/32 size nut driver (Figure A).
7. Slide the germicidal lamp into lamp opening.
8. Reinstall the lamp holder and plug lamp into connector.
10. Replace cover and align the oxidizing control knob with adjustment linkage by gently turning the knob until the
linkage clicks into place. Secure cover using the two retaining nuts.

WIRING OPTION 1
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 an 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 air handler operating. For 240VAC wiring install 5 amp inline fuses and use optional 240
VAC power cord, Part #PC-240.
WIRING OPTION 2
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. For 120V wiring install a 5 amp fuse to L1 connect the black wire to
L1, white wire to neutral, green wire to ground. Be sure power cord is secured with a 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. Optional power cord with pig tails is available along with a strain relief
connector for hard wiring. Part number PC-HW
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 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

TROUBLESHOOTING
• The LED should light when the furnace blower is running.
• Both lamps use the same multivoltage ballast.
If the LED does not light: 1. Check to be sure there is power to the unit.
2. Be sure lamp connectors are fastened securely.
3. If the LED still does not light, replace lamp(s).
4. If still not operating, replace ballast.
