Replacing Filters
Filters can be removed and installed from either side of the
unit. Install new filters in units that have one fan as follows:
1. Remove the side access panel (retain screws).
2. Remove the filter retainer clip (see Fig. 26).
3. Remove old filters by lifting and tilting them out of the fil-
ter track. (See Fig. 14 and 27.)
4. Reverse the procedure to install new filters.
To install new filters in larger units that have 2 fans, follow
the preceding steps, but use the factory-supplied filter hook
to slide filters within reach for removal. The filter hook is
shipped inside the unit in the filter track.
CAUTION

DO NOT OPERATE THE UNIT WITHOUT THE RE-
TURN AIR FILTERS IN PLACE.

possibly resulting in a small fire. Dirt buildup on compo-
nents can cause excessive current used resulting in mo-
tor failure.
