efficiency. The frequency of cleaning will vary from one
house to another. On average, the cells should be
cleaned every 3 months.
1. Remove access door, collecting cells and
prefilters.
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.
3. Rinse cells well with hot water (maximum 120°
F/49°C). Repeat washing process 2-3 times.
4. If dirt remains, fill up laundry tub with water and
DAX Detergent (1/2 cup), and dunk cells up and
down until water is dirty. Let cells soak in the
solution for 30 minutes. Then rinse cells well with
hot water (maximum 120°F/49°C).
5. Tilt cells on 45° angle on their short side, with
arrows pointing sideways. Allow to dry completely,
approximately 10-24 hours.
6. To wash prefilters, spray with DAX Detergent, rinse
and let dry. Do not wash in the same water as
collecting cells.
7. Place cells and prefilters back into cabinet. Close
door and turn power switch
ON
. If the performance
light does not come on or arcing occurs, turn Air
Cleaner
OFF,
remove cells and allow more drying
time.

Activated Carbon Filter Replacement
Carbon filters help remove odors from the air. If the
Air Cleaner has been equipped with optional carbon
filters, they should be replaced every 3 - 6 months.
Filters are NOT washable. Replacements are available
through your installer or dealer. To replace filters,
perform the following functions:
1. Turn Air Cleaner power switch
OFF
.
2. Turn off system fan.
3. Open
access
door.
4. Remove collecting cells from Air Cleaner.
5. Pull out used carbon filters. If the carbon filters do
not slide out easily, tilt them on a 45° angle and
they will fall out.
6. Put new carbon filters into Air Cleaner. Space
filters evenly across the discharge opening of Air
Cleaner. Never put more than 3 carbon filters in
the Air Cleaner, as this may cause a problem with
airflow.

SERVICE
Testing Air Proving Switch (APS)
The APS sensor must protrude through the plastic
bushing to work effectively. The sensor is very
sensitive and operation may be affected by cold
basement temperatures, an air exchanger, or a fresh
air duct connected to the cold air return just upstream
of the Air Cleaner.
The APS uses a Triac in its output circuit, which
affects the voltage sine wave. Using a regular digital
voltmeter will give a false reading. To check the output
from the APS, use a true RMS (root mean square)
meter to measure the output at terminals 1 and 4 of the
APS. The output should be between 105 and 115 VAC,
depending on the airflow across the sensor.
A neon lamp may be used to test the output of the
APS. Place the leads of the lamp across terminals 1
and 4 of the APS, or across the 120 V input of the
single output power board. If the lamp lights, the
voltage is sufficient for operation.
When the Air Cleaner is turned on without airflow,
the APS sensor heats up and after 30 seconds, opens
the circuit to turn off the power board. When the fan
starts up (the sensor is cooled), the circuit will close,
the power board is turned on, and the performance
light will come on.
The light on the power switch will be lit even when
the APS is open. If the power board fails to come on
with the fan on, check that the sensor is properly set
down, through the plastic bushing, in front of the power
box. To check the APS for proper operation, turn the
unit on and activate. The power board should come on
immediately, and then turn off in 30 seconds as the
sensor heats up. To check sensor, blow directly on it
lightly. This should activate the power board within 10
seconds. Service the sensor carefully. The sensor
leads are 120 V.
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
Electronic Air Cleaners use high voltage (low
amperage). Only trained personnel should perform
service. Use caution. Electric shock can cause injury
or death.
