Before performing service or maintenance operations on system, turn off main power to unit. Turn off accessory heater power switch if applicable. Electrical shock could cause severe injury or death. Step 1—General The 50JS and 50JX heat pumps are fully self-contained and designed for outdoor installation (See Fig.
INSPECT SHIPMENT — Inspect for shipping damage while unit is still on shipping pallet. If unit appears to be damaged or is torn loose from its anchorage, have it examined by transportation inspectors before removal. Forward claim papers directly to transportation company.
5. Tighten the tension buckle until it is taut. Lifting brackets must be secure in the handholds. 6. Attach field-supplied clevis or hook of sufficient strength to hole in the lifting bracket (See Fig. 8). 7. Attach the 2 safety straps directly to the clevis or hook at the 4 rigging brackets.

be in a conduit until they enter the duct panel; conduit termination at the duct panel must be watertight. Run the high-voltage leads through the power entry knockout on the power entry side panel (See Fig.
SPECIAL PROCEDURES FOR 208-V OPERATION 1. Disconnect the yellow primary lead (w110) from the trans- former. See unit wiring label (See Fig. 12 through 14). 2. Connect the yellow primary lead (w110) to the transformer terminal labeled 200v. Indoor blower-motor speeds may need to be changed for 208-v operation.
Fig. 22—Typical Heat Pump Operation, Cooling Mode 1. Hot gas from compressor flows through the 4-way valve and is directed to the outdoor coil. It is then condensed and subcooled through the coil circuits. Refrigerant leaves the outdoor coil by way of the OD Accurater in the bypass position to the liquid line.
2. Place SYSTEM switch in COOL position and FAN switch in AUTO position. Set control below room temperature. Observe that cooling cycle shuts down when control setting is satisfied. 3. Place system switch in HEAT position. Set control above room temperature.
The charging label and the tables shown refer to system tempera- tures and pressures in cooling mode only. A refrigerant charging label is attached to the outside of the service access door. If charge level is suspect in Heating mode, reclaim all refrigerant and charge to nameplate amount.
INDOOR AIRFLOW AND AIRFLOW ADJUSTMENTS For heating and cooling operation, the recommended airflow is 350 to 450 cfm for each 12,000 Btuh of rated cooling capacity. for units with optional electric heat, the airflow must not be reduced below the levels stated in Tables 2A and 2B.
To change the speed of the blower motor (BM), remove the fan motor speed leg lead from the blower relay (BR). This wire is attached to IGC terminal BM for single-phase and 3-phase units. To change the speed, remove and replace with lead for desired blower motor speed.

Failure to follow these warnings could result in serious injury or death: 1. Turn off electrical power to the unit before performing any maintenance or service on this unit. 2. Use extreme caution when removing panels and parts. As with any mechanical equipment, personal injury can result from sharp edges.
exists, be sure that all supply- and return-air grilles are open and free from obstructions, and that the air filter is clean. When necessary, refer to Indoor Airflow and Airflow Adjustments section to check the system airflow.
