Downflow Furnace Installation - Trane FD145CLFR000D Installation Operation & Maintenance

Installer's Guide
UPFLOW AIR HANDLER APPLICATIONS ONLY
9. Position the baffle onto the air cleaner as indi-
cated in Figure 17. The baffle should be posi-
tioned on the leaving air side of the air cleaner
cabinet opposite the power door. Ensure that the
bracket is located correctly inside the air cleaner
enclosure so that the baffle or screws do not
interfere with the filter cell installation. (See Figure
17 inset.)
NOTE: The upflow air handler baffle is required
to protect the air cleaner in the event of a drain
pan overflow. This baffle is required for all
upflow air handler installations.

10. Install unit in place and secure.
11. Reinstall the FIELD CHARGER and lock into place by
bending one locking tab on the cabinet. See Figure 18.
12. Reinstall the PRE-FILTER and COLLECTION CELLS.
13. Each cell must be oriented with handles toward the
front.
14. The door can be installed in either direction. Deter-
mine which direction will best allow access to the
latches and 24 Volt power cord. Insert the 2 tabs on the
door into the slots in the cabinet flange and rotate the
door into the closed position. Rotate the two quarter-
turn latches on the Power Door inward. See Door
Operation Section C.
15. Remove stickers (two stickers both are 5.5" x 7.5")
from packet and attach to furnace, air handler, or
ductwork in a location visible to the homeowner.
16. Demonstrate Maintenance (Section H) and Door
Operation (Section C) to the homeowner.

DOWNFLOW FURNACE INSTALLATION

NOTE: On 90% Downflow Furnaces, the intake and
exhaust (flue) are located on top. A field supplied
transition is needed between the furnace and the air
cleaner. The transition must be long enough to avoid
any interference between the intake and exhaust pipe
routing and the door of the air cleaner. The door and
internal components must be removable for servicing.
NOTE: Optional Side Vent Kit BAYVENT500A may be
used if a 90% downflow furnace is installed with a
whole house air cleaner. This optional side venting
kit allows access to the front door of the whole
house air cleaner for easy filter cleaning and
maintenance. This kit eliminates the need for the
transition between the furnace and air cleaner.
1. Rotate the two quarter turn latches on the Power Door
outward then rotate the Power Door to remove it from
the cabinet. Remove the PRE-FILTER, FIELD
CHARGER, and both COLLECTION CELLS. Set the
components aside until the cabinet is installed and the
indoor unit is in place.
NOTE: Cut the front duct flange 2" from each side and
fold flat to clear the Power Door latches. Some applica-
tions may require a transition for piping clearances.
See Figure 19.

NOTE: Remove filter rack from downflow Furnace and
discard.
2. Bend the 4 mounting tabs down on the two sides of the
air cleaner cabinet. These can be used to attach the air
cleaner cabinet to the furnace. See Figure 20.

3. Install the self-adhesive gasket material on the side of
the air cleaner cabinet flange that will mate with the
indoor unit. This flange has a double set of holes. See
Figure 16.
