1 Rated in accordance with ARI Standard 110, utilization range “A”.

2Below 0°F, the control system stops the compressor and allows the electric heat accessory to cycle at its standby capacity.

3Operation below this temperature is permissible for a short period of time when a unit is required to heat the conditioned space up to 50°F.

LOCATION

/

1.The outdoor units must be installed outside the building. The outdoor fans are the propeller type and are not suitable for use with duct work.

2.The outdoor and indoor units should be installed as close together as possible and with a minimum number of bends in the refrigerant piping. Refer to REFRIGERANT PIPING for additional information.

3.The outdoor unit should not be installed beneath windows or between structures where normal operating sounds may be objectionable.

WARNING: The outdoor unit should not be installed in an area where mud and/or ice could cause personal injury. Remember that condensate will drip from the underside of the unit coils during heat and defrost cycles and that this condensate will freeze when the

temperature of the outdoor air is below 32 F.

4.All units require certain clearances for proper operation and service. Refer to General Installation Form 55.70-N1 for additional guidelines.

CAUTION: Care should be taken to protect the unit from tampering and unauthorized persons from injury. Screws on access panels will prevent casual tampering. Additional safety precautions such as fences around the unit or locking devices on the panels may be advisable. Check local authorities for safety regulations.

1These compressors are fully hermetic.

2These PSC motors are directly connected to the outdoor fans and have inherent protection, ball bearings and a 48 frame. Rotation (when viewing the shaft end of the motor) - 090=CW, 120=CCW.

3Includes outdoor unit and matched indoor blower unit, but no piping. Refer to Table 6 for refrigerant line charge.

CAUTION: Do Not loosen compressor mounting bolts.

COMPRESSOR CRANKCASE HEATER

$

A ''B

CAUTION: Do not attempt to start the compressor without at least eight hours of crankcase heat or compressor damage will occur.

If a unit has just been installed or the unit disconnect switch has been open for a long period of time, move the system switch on the room thermostat to the “OFF” position before closing the unit disconnect switch. Eight hours of crankcase heat are required to drive the liquid refrigerant out of the compressor before the compressor can be started.

The field-supplied disconnect switch must be suitable for an outdoor location. Although it should be installed near the unit, do NOT secure it to the unit cabinet.

Refer to Figure 3 for typical field wiring.

CONTROL WIRING

Refer to Figure 4 for the location of the control wire access opening through the front of the unit.
