All units contain four filters. The filter racks on these units will
receive either 1" or 2" filters. Filters can also be installed in
the building at a suitable return air location if an economizer
or outside air accessory is not used. Filters must always be
used. They should be inspected once a month and thor-
oughly cleaned or replaced if it appears they are beginning to
accumulate excessive dirt.
To install the filters, remove the filter access panel as shown
in Figure 2.
NOTE: Filters must be installed with “Air Flow” arrows point-
ing inward -- toward the indoor coil. In the event the
spacers in the filter section are removed, they must
be reinstalled in their original position.
Slide filters all the way into the filter racks provided. When
more than one filter in a filter rack is required, they must butt
each other when sliding into position. Replace the filter
access panel.
