DUCT CONNECTIONS

To ensure proper operation, ensure the blower motor is oriented as shown in Figure 5 for horizontal airflow installations.

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 PLACEMENT

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.

WARNING

TO AVOID PERSONAL INJURY OR DEATH, DISCONNECT THE ELECTRICAL POWER BEFORE ELECTRICALLY CONNECTING THE UNIT.

THERMOSTAT WIRING

When an electric heater is installed, the thermostat wiring will be made at the heater accessory box.

If a unit is installed without electric heaters, the low voltage wiring to the blower section can be cut, either in the control box area or in the blower section, to allow splicing-in of field-installed wiring, or con- nect to terminal strip in unit control box.

See the unit wiring diagram for electrical connections.

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. 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 and the room thermostat. Refer to Figure 2 for proper thermostat wiring and Figures 3 and 4 shows the low voltage field connection.
