Air Filters

CAUTION
!
UNIT OPERATION HAZARD
Failure to follow this caution may result in property damage.
Never operate your unit without filters in place. An accumulation of
dust and lint on internal parts of your unit can cause loss of efficiency
and blower motor and/or compressor damage.
The air filter(s) should be checked every 3 or 4 weeks and changed or
cleaned whenever it becomes dirty. Dirty filters produce excessive stress
on the blower motor and can cause the motor to overheat and shut down.
This unit must have air filters in place before it can be operated. These
filters can be located in one of at least two places. In many applications,
the installer will provide return air filter grilles mounted on the wall or
ceiling of the conditioned structure. In the instance of filter grilles, the
filters can simply be removed from the grille and replaced.
The other typical application is an accessory filter rack installed inside
the unit itself. The following information is given to assist in changing
filters used in these internal filter racks.
Filter kits are available as a purchased accessory or a factory installed
option. The same filter kit is included with the accessory economizers
and factory installed economizers.
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.
