RETURN AIR FILTERS

TYPICAL UPFLOW RETURN AIR FILTER INSTALLATIONS
Filters are factory supplied for these furnaces. These
furnaces require high velocity type air filters. The filters
may be located within the furnace blower compartment for
UPFLOW furnaces in either a BOTTOM or SIDE (left side
or right side) return air inlet. Some filters may need to be
trimmed for side or bottom filter use.
NOTE: For upflow 5 ton airflow models where the airflow
requirement exceeds 1800 CFM - Models will require re-
turn air openings and filters on: (1) both sides, or (2) one
side and the bottom, or (3) just the bottom.
The furnace and the bottom filter rack, BAYRACK960,
installation can be seen in Figures 13, 14 and 15.

ALTERNATE FILTER RACK INSTALLATION FOR BOTTOM
RETURN
The following checklist should be used when installing a
bottom return filter on an upflow furnace:
a. Remove the filter.
b. Remove the bottom panel.
c. With the filter removed, the filter rack is compressed
and then inserted into the bottom of the furnace.
The retaining screw/pin on each side inserts into en-
gagement holes at the bottom of the furnace cabinet
side.
d. Reinstall the furnace filter in the bottom position by
inserting the chamfer end first into the filter rack.
See Figures 13-16.
NOTE: There is no internal right side filter access with
the use of the filter rack on furnace models *UD060R9V3,
*UD2C080B9V4VA, and *UD2C100B9V5VA.
