speed motor drops the air flow to a point the sensor will
not activate the power board.
Installation
Carefully remove the Air Cleaner from the carton.
Remove the cells and prefilters from the unit. Remove the
access door from the unit by removing the screw on the
end of the retaining link in the enclosure. Lower the
access door and remove the nuts securing the hinge to
the enclosure.
Remove the screws securing the electrical
compartment cover.
The hole in wall or ceiling should be made to fit the Air
Cleaner opening as closely as possible. The opening
should be framed to provide adequate support for the Air
Cleaner. Before mounting the Air Cleaner, cover the
framing and close the opening to within 1/4 in. (.63 cm) of
the dimension of the rear of the enclosure of the Air
Cleaner. Match the finish to the existing wall.
Mount the Air Cleaner into the framed hole and slide
into the duct until the front flange is flush with the wall.
Secure the Air Cleaner to the frame using sheet metal
screws. Do not overtighten screws as this may distort the
enclosure. Once the unit is secured to the wall, the access
door and retaining link can be replaced.
Wiring
Wiring should only be performed by qualified
personnel only. All wiring must comply with all applicable
codes and standards. The voltage of the power source
must match the voltage indicated on the Air Cleaner. The
Air Cleaner should operate ONLY when the system fan is
running. Make sure the Air Cleaner is properly grounded.
Wire the Air Cleaner directly to the power source. The
APS will power the Air Cleaner when there is sufficient
airflow to activate the sensor.
Connect the black lead of the Air Cleaner to the line
side of power source. Connect the white lead to the
neutral side of the power source. Connect the green lead
to ground. See Fig. 5.
SYSTEM CHECK
Perform the following system check before operation.
1. Replace the prefilters and collecting cells. Close
access door and replace thumb screw.
2. Turn Air Cleaner power switch ON. Ensure system fan
is operating. The performance indicator light should
be lit showing that the Air Cleaner is operating.
Note: There may be some arcing or snapping sounds
from the collecting cells. This is normal when the unit is
new. In about 2 weeks, as the sharp edges of the cells
become smoother, the arcing will disappear.
OPERATION
The Air Cleaner will run as long as there is airflow
through the ducts. The Air Cleaner will not run if the
system fan is off. For proper operation, follow these
simple steps:
1. Run heating/cooling system fan continuously, and on
low speed if available.
2. Remove any furniture which may block the return air
grille, so that air moves freely to the furnace/ air
conditioner.
3. Check for proper operation of the system fan.
WHITE DUST
After installation of the Air Cleaner, you may notice
some white dust on tabletops and shelves. Most large
particles such as lint, are too heavy to remain airborne
and tend to settle quickly, never reaching the Air Cleaner.
This white visible dust is normally referred to as “clean
dust.” As the Air Cleaner is removing the dark and
staining particles from the air, the lint will also be cleaner.
Lint dust is most noticeable on dark furnishings; in
homes containing new carpeting; and where there is a lot
of household traffic from occupants and pets. To reduce
lint dust, use continuous fan operation and keep return
vents unrestricted to create an efficient airflow.
Note: The Air Cleaner does NOT produce more lint or
dust.
MAINTENANCE
It is important to follow a scheduled maintenance for
maximum performance of the Air Cleaner.
Cell And Prefilter Cleaning
The collecting cells and prefilters must be cleaned on
a regular basis for the Air Cleaner to function at its peak
efficiency. The frequency of cleaning will vary from one
location to another. On average, the cells should be
cleaned every 3 months.
1. Turn OFF power switch and wait 15 seconds. Open
access door and remove collecting cells and prefilters.
In a ceiling application open the door carefully.
2. Place cells in a laundry tub. Rinse with hot water and
spray completely with DAX Detergent (or a non-
chlorine, non-corrosive, non-abrasive liquid household
detergent.) Allow detergent to run down both sides of
plates and ionizing wires. Let stand for 5 minutes and
rinse with hot water. Repeat process three times.
3. Rinse cells well with hot water (maximum 120°F/49°
C).
4. If dirt remains, let cells soak in a solution of DAX
Detergent and hot water for 30-60 minutes, then rinse.
5. Tilt cells on 45° angle on their short side, with arrows
pointing sideways. Allow to dry completely,
CAUTION
Damage to cells may occur if improperly handled or
washed. Do not wash cells in a dishwasher. Never use
any object to clean between the cell plates, as this may
cause damage to plates or ionizing wires. Never place
cell in oven to dry.The edges of the cell may be sharp -
handle with care.

WARNING
Electrical shock can cause injury or death. Be certain
main line disconnect switch is off before wiring.
