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. 27).
3. Remove old filters by lifting and tilting them out of the filter
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.
