OPTIONAL FILTER RACK INSTALLATION FOR SIDE
RETURN AIR ON UPFLOW FURNACES (Left or Right) -
BAYRACK960
The following checklist should be used when installing a
right or left side return filter on an upflow furnace:
a. Remove the filter.
b. Leave the bottom panel in place.
c. Make side cutout by following the directions in the
“Return Air Duct Connections” section on page 9.
d. Compress the filter rack and reinstall in the side
position on the furnace. Confirm that the upper
retaining pin/screw locks into the engagement hole in
the blower deck and the lower pin/screw rests against
the side of the bottom panel. See Figures 14, 18-20.
e. Reinstall the furnace filter in the side position by
inserting the chamfer end first into the filter rack.
