OPERATING YOUR ELECTRONIC AIR
CLEANER
Your new electronic air cleaner is designed to operate as part of
your heating/cooling system. After the cleaner's power switch
is turned ON, the cleaner will operate whenever the furnace or
air-handler blower is running.
Your electronic air cleaner will perform at maximum efficiency
if these recommendations are followed:
•
Consider running the heating/cooling system blower contin-
uously—day and night, winter and summer. Continuous
blower operation provides for constant air filtration. It may
also contribute to greater personal comfort since continuous
blower operation minimizes temperature differences through-
out the home.

Furthermore, systems equipped with humidifiers offer the added
benefit of having the air humidified during heating.
•
Supply-air and return-air grilles should not be blocked. Drapes,
furniture, and toys are some of the items commonly found ob-
structing grilles. Restricted airflow reduces the efficiency of the
air cleaner, as well as that of the whole comfort system.
•
The electronic air cleaner must be properly maintained.

START-UP PROCEDURES

1. Set the temperature control selector on your indoor thermo-
stat. Choose a setting above current room temperature if heating
is required. Set the temperature control selector below room
temperature if cooling is needed.
2. Set the FAN mode. When set to AUTO, the air cleaner and
system blower will run only while the thermostat operates the
heating or cooling section. When the FAN mode is set at the ON
position, the air cleaner and blower will run continuously—re-
gardless of whether the cooling or heating section is operating.
3. Select HEAT, COOL, or AUTO.
4. Turn the air cleaner's power switch ON. The power switch
for the DUCT-TYPE cleaner is located on the door panel. (See
Fig. 4.)

NOTE: The operation light indicates that power is available to
the cells. It does not indicate that power is available to the unit.
NOTE: An occasional arcing (snapping) noise is normal during
the operation of your air cleaner. Continuous arcing, however,
indicates that cleaning is required. Refer to page 4 for directions
on cleaning your electronic air cleaner.

PERFORMING ROUTINE MAINTENANCE

With the proper maintenance and care, your electronic air
cleaner will operate economically and dependably. Maintenance
can be accomplished easily by referring to the following direc-
tions. However, before performing any maintenance, consider
these important safety precautions:
•
DISCONNECT ALL ELECTRICAL POWER TO THE AIR
CLEANER BEFORE PERFORMING ANY SERVICE OR
MAINTENANCE.
NOTE: THERE MAY BE MORE THAN 1 ELECTRICAL
DISCONNECT SWITCH.
•
ALTHOUGH SPECIAL CARE HAS BEEN TAKEN TO
MINIMIZE SHARP EDGES IN THE CONSTRUCTION OF
YOUR UNIT, BE EXTREMELY CAREFUL WHEN HAN-
DLING PARTS OR REACHING INTO THE UNIT.
The prefilter and ionizer/collector cells should be checked reg-
ularly. Accumulated dirt will need to be removed from these
components to maintain efficient air filtration.
Regular inspection allows you to determine the cleaning
schedule best suited to your home's operating conditions. The
first electronic cleaning of your home may collect more par-
ticles over a shorter period than will be normal for future
operation.

ELECTRICAL POWER
DISCONNECT
PROCEDURE
To disconnect the electrical
power to your air cleaner, sim-
ply push its power switch to the
OFF position. You may con-
tinue to operate the rest of your
comfort system, or turn the
power off according to the
manufacturer's specifications.
