Air Return Orientation
The heat pump can be ordered as left or right return from
the factory. This must be specified at time of order as the physi-
cal construction of the two configurations is different. Refer to
the DIMENSIONS section of this manual or the specification
documents for physical dimensions of the units.
Fan/Blower Outlet Orientation
TF-Series heat pumps have a field configurable blower. Its
default location from the factory is in the top of the unit, provid-
ing a 90 degree turn in the airflow. It can easily be placed in the
side of the unit for straight through airflow.
To switch the location of the fan outlet:
1. Turn the power off to the unit.
2. Remove the 4 screws that hold the upper front access
door in place and remove the panel by pulling up on
the handle and then outward from the bottom.
3. Disconnect the two wiring harnesses and ground wire
from the blower motor.
4. Remove the vertical blower access panel adjacent to
the blower by removing its 4 screws.
5. Remove the screws inside the air chamber that hold
the bottom of the blower to the brackets, and the 4
screws in a line on the top of the unit that hold the
blower panel in place. Slide the blower in its panel
away from the air coil, and lift the air coil end of the
panel. Pull the blower assembly out through the top of
the cabinet and set it on the floor.
6. Disconnect the plenum heater extension from the
blower housing and from the access panel by remov-
ing the screws.
7. Insert the shortened blower assembly through the side
opening of cabinet and secure with 4 screws. Use the
blower panel that was formerly in this location to cover
the opening in cabinet top, and secure with 4 screws.
8. Reconnect both wiring harnesses and ground wire.
9. Re-install the upper front cabinet door and secure with
4 screws.
Note that with the blower in the side discharge position, an
accessory plenum heater must be mounted in the ductwork out-
side the unit.
Also note that the blower assembly can be installed (in
either the top or side discharge positions) with the fan motor
facing either the back or front of the unit, and can be switched
depending on what is convenient for any particular installation
location.
