MAINTENANCE
AND INSTALL
A LOCKOUT
TAG.
2. When
removing
access
panels
or
performing
maintenance
functions
inside
your
unit,
be
aware
of
sharp sheet metal parts and screws. Although
special care
is taken
to reduce
sharp
edges
to
a minimum,
be
extremely
careful
when
handling
parts
or reaching
into
the unit.
Air Filters
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.
Table 1 indicates the correct indoor filter size for your unit. Refer
to Fig. 2 to access filters installed in the accessory filter rack. If
using an Accessory Filter Rack, refer to the Installation Instructions
provided with it for correct filter sizes and quantities.

To replace or inspect filters in accessory filter rack (See Fig. 2):
1. Remove the filter access panel using a 5/16-in. nut driver.
2. Remove the filter(s) by pulling it out of the unit. If the
filter(s) is dirty, clean or replace with a new one.
When installing the new filter(s), note the direction of the airflow
arrows on the filter frame.
If you have difficulty locating your air filter(s) or have questions
concerning
proper filter maintenance,
contact your dealer for
instructions. When replacing filters, always use the same size and
type of filter that was supplied originally by the installer.
