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.

!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.

Replacing or inspecting filters in units with econom- izers

Small Chassis (See Fig. 4)

1.Remove return air duct cover at rear of unit using a 5/16-in. nut driver.

2.Remove the filter(s) by pulling it out and through the unit duct opening. If filter is dirty, replace both filters with new ones.

When installing the new filters, note the direction of the airflow arrows on the filter frame, which should be pointing at the indoor coil.

3.Reinstall duct cover ensuring opening is air and water tight.

Large Chassis (See Fig. 5)

1.Remove filter access door using a 5/16-in. nut driver.

2.Remove the filter(s) by pulling it out and through the unit filter access door. If filter is dirty, replace both filters with new ones.

Units with bent indoor coils, install 24 x 18 x 1 (610 x 457 x 25 mm) filter first and then install 24 x 16 x 1 (610 x 406 x 25) filter.

When installing the new filters, note the direction of the airflow arrows on the filter frame, which should be pointing at the indoor coil.

3.Reinstall filter access door ensuring opening is air and watertight.
