Power
The unit includes adapters to operate on 12V/500mA DC power or 115V/60Hz/300mA,
220V/50Hz/200mA, or 230V/60Hz/275mA AC power.
Installation
Use suction cups on bottom to anchor the unit to any smooth, flat surface. Write current

SYSTEM OPERATION
For optimal results, let the system run continuously, even when you are not in the room.
Connect the power cord to the back of the unit then plug it into the appropriate AC or DC
power source. Use the 3-position power switch to select High (11), Normal (I), or Off (0):
HIGH (II) - Fan operates at highest speed for maximum purification
The UV bulb activates (look for a blue glow) and air purification begins.
NORMAL (I) - Fan operates at moderate speed

Replacing the UV Bulb
Like all light bulbs, UV bulbs have a limited life span. Unlike regular light bulbs that work
until they burn out, UV bulbs lose their germicidal effectiveness over time (after about
9,000 hours) and must be replaced even though they may still produce light.
After approximately 1 year of continuous use, the UV bulb will lose power and have to be
replaced. NOTE: One hour of bulb life is lost each time it is turned on and off.
Follow these steps:
1. Unplug the unit from the electrical outlet.
2. Unscrew the 4 inset screws on the 4 corners of the bottom panel and remove the
cover.
3. Allow 5 minutes for the bulb to cool, then locate the white bulb socket and pull the
bulb straight out.

4. Replace with a new Dometic UV bulb (model 4210804). Use of any other bulb will
void the warranty. Insert the bulb prongs firmly into the socket. Cover old due-
date sticker with new one and write in the current month and year.
5. If any interior cleaning is required, do it now. (See "Cleaning" below.)

Replacing the Removable Nano-Mesh Divider
Figure 2: Removing the nano-mesh divider
Follow these steps:
1. While the cover is off (see "Replacing the UV Bulb" for instructions), lift the nano­
mesh divider out of the slots.
2. Insert the new nano-mesh divider lengthwise into the slots. It does not matter
which side of the nano-mesh faces the bulb.
Cleaning
Exterior - Use a soft, dry cloth to wipe away any dust or debris that may accumulate
around the vent holes.
Make sure the unit is unplugged before opening the case.
Interior -
the UV Bulb" for instructions.) Blow away general dustiness with canned air suitable for
use on computers.
Fan - When replacing the UV bulb or if you notice a reduction in air flow, dust the internal
fan using a soft brush.
Removable Nano-Mesh Divider - If you notice a reduction in air flow, clean the
removable 1" x 2" (25mm x 50mm) photocatalytic nano-mesh divider that separates the
fan compartment from the bulb compartment. Lift it out of the slots then brush off the
debris or clean it with dish soap and water. Let it dry, then slide it back into position. (A
replacement nano-mesh divider is included with each replacement UV
Non-Removable Nano-Mesh Strips - If necessary, dust the non-removable nano-mesh
strips gently with a soft brush to remove debris.
UV Bulb - If the unit is in a very smoky or dusty area we suggest you clean the UV bulb
periodically with a soft cloth and alcohol. Allow the bulb to cool before cleaning. Under
these dusty conditions, also clean the fan and nano-mesh divider as described above.
TROUBLESHOOTING
No power, unit does not turn on (no fan noise).
1. Make sure the unit is plugged in at the back of the unit and at the power source.
2. Make sure the power switch is not in the OFF (0) position.
3. Verify that the power source is working.
A replacement 1" x 2" (25mm x 50mm)
nano-mesh divider is included with each
replacement UV bulb.
Replace the photocatalytic nano-mesh
divider that separates the fan compartment
from the bulb compartment each time you
change the UV bulb.
