Return Air Filters - Trane UHMB060ACV3VA Installer's Manual

Rotate the channel downward (or remove by lower-
ing the front edge of the channel and pulling for-
ward). Slide the bottom return air panel out of the
cabinet. Rotate the front channel to its original
position and reinstall the two 5/16" screws.
8. The horizontal installation of the upflow
furnace requires an external filter section. Do
NOT use the bottom return filter within the
furnace. Filter kits are available for horizon-
tal applications.
9. Connect duct work to furnace. See Outline Drawing
for supply and return duct size and location. Flex-
ible duct connectors are recommended to connect
both supply and return air ducts to the furnace. If
only the front of the furnace is accessible, it is
recommended that both supply and return air
plenums are removable.

Filters are factory supplied for these furnaces. These
furnaces require high velocity type air filters. The fil-
ters may be installed within the furnace blower com-
partment 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 return air openings and filters on: (1) both
sides, or (2) one side and the bottom, or (3) just the
bottom. The filter rack installation is not allowed for
right side return on the following models:
*UHMB060ACV3V, *UHMB080ACV3V & *UHMC100ACV4V.
The furnace and the bottom filter rack, BAYRACK960,
installation can be seen in Figure 11.
The furnace filter in the bottom or side configuration
can be removed by simply turning the two latches on
the blower door and tilting the door forward.
The Filter rails are spring loaded for automatic adjust-
ment to allow standard size, locally obtainable replace-
ment filters. The filter rack itself slides to adjust to the
required width needed for bottom or side return (See
Figure 12).
