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.

Plenum Heater Installation (Optional)
Be sure to specify the type of installation anticipated,
since the plenum heater models are different for internal or
external (duct) installation.
1. Vertical R-series, blower in top discharge position:
Plenum heater is mounted inside heat pump cabinet. See
diagram on following page. Remove the screws from the
cover plate, remove the cover plate, and place the plenum
heater in the cutout. Slide it up and secure the bottom
flange with three cover plate screws. Use the indicated
knockouts on the heat pump cabinet for electrical connec-
tions.
When installation is complete, check the appropriate
box of the label on the unit door to indicate which size
heater was installed.
2. Vertical R-series, blower in side discharge position OR
RH-series:
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 mount-
ed in an approved position as per its instructions.
