Fig. 4 – Self-Contained Attic Installation
AFTER INSTALLING AIR CLEANER
WARNING
Eye and skin damage may result from direct exposure
to the light produced by the lamps used in this product.
Make sure the Air Cleaner is OFF and UNPLUGGED
before the lamp access panel is open.
CAUTION
Do not touch the lamp glass with bare hands. Always
use the gloves provided when installing the lamps. The
oil from your hands may reduce the effectiveness of
the lamp. The lamp may be cleaned with a soft cloth
dampened with water to remove finger prints.
1. Install the two UV lamps into the lamp holders.
Follow the instructions given in the maintenance
instructions. Use the cotton gloves provided
when handling the lamps. Replace the four
filters (see Fig. 5), close the filter access door
and replace the lamp access panel. Ensure all
the screws are in place and tight. Do not over
tighten.
2. After the installation, the unit must be checked
for sealing, both for air and light leakage. Any
leaks to the Air Cleaner must be sealed with
aluminum tape.
3. Turn the Air Cleaner ON and check for any
leaks of light. There must be no visible blue light
from the Air Cleaner. If you see any blue light
from the duct connections cover the holes with
aluminum tape.
CAUTION
When the unit is new or after the lamps have been
replaced there may be a temporary odor. An odor may
also occur with high concentrations of chemicals in the
home such as paint or strong cleaning solutions. Both
odors are temporary and should dissipate within a
short time.
Never use the Air Cleaner without all of the filters in
place and all cover panels and doors closed. Make
sure all the screws are in place.
OPERATING INSTRUCTIONS
The Air Cleaner is designed to run continuously to
provide clean, filtered air 24 hours a day. The fan
on the heating/cooling system, to which the Air
Cleaner is dependent on for circulated air, should
be on 'continuous' setting.
Running the Air Cleaner intermittently will
shorten the effective life of the lamps.
The Air Cleaner plugs into a regular 120 volt outlet
and is controlled by a switch located on the side of
the unit, near the cord.
Note: Do not allow the cord to be placed where it
may be walked on or allow anything to roll over it.

MAINTENANCE

Make sure to turn the Air Cleaner OFF before
performing any maintenance or removing any filters.
For efficient operation, the filters must be changed
on a regular basis. If you notice a reduction in air
flow from the system, check the filters.
