The filter rack or drop chute will be located between the return air plenum and the return air opening of
the furnace. Slide dirty filter out of the filter rack. Clean the filter by vacuuming, rinsing with tap water,
hosing or dipping in an ordinary detergent solution. Replace the completely dry filter in the rack.
If an optional Thermo Pride filter rack is used with the furnace, it will serve as a template to scribe a mark
for the return air opening on the casing. Place the filter rack on the casing 1 inch up from the bottom of
the furnace on either the Left or Right side of the cabinet. Align the back of the filter rack with the back
of the cabinet, and place the securing flange against the casing for locating the return air opening.
Figure 12
NOTICE: While scribing the return air opening, the filter rack can be held into position by tape or similar
means.
Position the open end of the filter rack so that it is accessible for filter replacement. Once the filter rack is
positioned correctly, scribe a line along the inside of the securing flange of the filter rack on three of the
sides. To scribe a line on the fourth side, on the open end, use the open end support for a guide. Remove
the filter rack and cut the return air opening in the casing.
Now the filter rack can be permanently attached to the furnace with screws or pop-rivets along the
securing flange. Connect the return plenum to the filter rack and slide the filter into place.
Use of Non Thermo Pride Filter Retention Means
If a method other than the Thermo Pride filter rack is selected for retention of the filter and/or use of a
different filter type is desired, see Table 3 for minimum size guidelines for selecting a filter system for the
furnace.
