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

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.
