Air Outlet Orientation
For vertical R -series units, the air discharge location is in a
fixed position, blowing upwards.
For horizontal RH -series units, as is typical for heat pumps
of this type, the air discharge can be field installed in either the
side (default position, opposite the air return) or the end (90° to
the air return). To switch it to the end position, before ductwork
is installed:
1. Ensure power to the unit is off.
2. Remove the screws that hold the access panel adjacent to
the blower panel in place and remove the access panel by
pulling up on the handle and then outward from the bot-
tom.
3. Repeat for the access panel with the blower mounted in it.
Ensure the wiring harnesses move freely while removing
the blower.
4. Disconnect the wiring harness plugs from the motor, and
the ground wire from the fan housing.
5. Place the blower in front of its new ‘end’ location, making
sure the motor is facing toward the adjacent access panel.
Flip the blower and panel over if required. Reconnect both
motor plugs and the housing ground wire.
6. Install the blower and secure panel with the screws.
7. Install the adjacent access panel and secure with the
remaining screws.
Note for both R and RH units, for blower motor servicing
the entire blower can be removed out the adjacent access panel
by removing two bolts:
Air Return Orientation
The heat pump can be ordered as left or right air return
from the factory. This must be specified at time of order as the
physical construction of the two configurations is different. Re-
fer to the Dimensions section toward the end of this manual for
physical dimensions of the units.
LEFT RETURN RIGHT RETURN
Plenum Heater Installation (Optional)
Be sure to order the ‘internally mounted’ type of ple-
num heater, since the plenum heater intended for external
installation in larger heat pumps has a cage which is too
wide for the smaller ductwork used with these smaller heat
pumps.
Plenum heater should be installed in the air discharge duct
outside the heat pump cabinet in a manner that allows all of the
airflow to pass through it to prevent any hot spots in the heater
elements. Ensure that the plenum heater is mounted in an ap-
proved position as per its instructions. (If there is an airflow
direction arrow on the plenum heater, it can be disregarded.)
