ELECTRICAL CONNECTIONS
NOTE: The units are designed for operation on 60 Hz current and at
the voltages shown on the rating plate. All internal wiring in the unit is
complete. For the PHB**CC and PHD**CC units, the power supply
connection for the heater and unit will be at the circuit breaker in the
heater control box. For all others, the power supply may be brought
into the contactor (refer to unit wiring diagram supplied with unit).
Ensure 24 volt wiring is connected between the unit control panel

HORIZONTAL AIRFLOW INSTALLATIONS
(24, 30, 36, 42 AND PHB48 MODELS)
Two three-inch collar connections and two square flanges are shipped
with the unit. The collar connections are located in the return air
opening of the unit. The square flanges are inside the unit blower
compartment. The square flanges can be used for either connect-
ing 16x16 ductwork to the unit or used with a Horizontal Duct Cover
kit (CHK001A).
To install the collar connections, remove the two collars, reverse and
snap them back into place in the outlet and inlet openings. Be sure
the flanges are to the outside of the unit. Secure with screws pro-
vided.
HORIZONTAL AIRFLOW INSTALLATIONS
(PHD48/60 and PHB60 models only)
These units are equipped with 14x14 square supply and return air
openings for horizontal air flow. The openings are flanged for ease
of duct connection. A 16x16 Horizontal Duct Cover kit (CHK001A)
can be used with the clips provided with the unit.

Thermostat should be mounted 5 feet above the floor, on a vibration
free inside wall in a room or a hallway that has good air circulation.
Movement of air should not be obstructed by furniture, door, draper-
ies, etc. The thermostat should not be mounted where it will be af-
fected by drafts, hot or cold water pipes or air ducts in walls, radiant
heat from fireplace, lamps, the sun, television, etc. Consult the In-
struction Sheet packaged with thermostat for mounting instructions.
