Recommended Cooling Time (Minutes) Fig. 91 — Advanced Scroll Temperature Protection Label 120 110 100 90 80 70 60 50 40 30 20 10 0 0 10 20 30 40 50 60 70 80 90 Compressor Unloaded Run Time (Minutes) *Times are approximate. NOTE: Various factors, including high humidity, high ambient temperature, and the presence of a sound blanket will increase cooldown times. Fig. 92 — Recommended Minimum Cool-Down Time After Compressor is Stopped* Crankcase Heater — Each compressor has a crankcase heater to prevent absorption of liquid refrigerant by oil in the crankcase when the compressor is idle. Since 115-v power for the crankcase heaters is drawn from the unit control circuit, main unit power must be on for the heaters to be energized. IMPORTANT: After a prolonged shutdown or service job, energize the crankcase heaters for 24 hours before starting the compressor. EVAPORATOR-FAN MOTOR PROTECTION — A manual reset, calibrated trip, magnetic circuit breaker protects against overcurrent. Do not bypass connections or increase the size of the breaker to correct trouble. Determine the cause and correct it before resetting the breaker. CONDENSER-FAN MOTOR PROTECTION — Each condenser-fan motor is internally protected against overtemperature. They are also protected against a severe overcurrent condition by manual reset, calibrated trip, magnetic circuit breakers on a common circuit. As with the circuit breakers, do not bypass connections or increase breaker size to correct trouble. Determine the cause and correct it before resetting the breaker. HIGH-PRESSURE SWITCHES — Settings for these switches are shown in Tables 104A and 104B. If either switch trips, that refrigerant circuit will be automatically locked out by the controls. To reset, recycle control power to unit. Table 104A — Pressure Switch Settings (psig) SWITCH CUTOUT CUT-IN High 650 10 500 15 164 Table 104B — Pressure Switch Settings (kPa) SWITCH CUTOUT CUT-IN High 4482 69 3447 103 Relief Devices — All units have relief devices to protect against damage from excessive pressures (i.e., fire). These devices protect the high and low side. Control Circuit, 115 V — This control circuit is protected against overcurrent by a 10-amp circuit breaker. Breaker can be reset. If it trips, determine cause of trouble before resetting. Control Circuit, 24 V — This control circuit is protected against overcurrent by two 10-amp and four 3.2-amp circuit breakers. Breakers can be reset. If a breaker trips, determine cause of trouble before resetting. Gas Heat (48P Only) LIMIT SWITCHES — The maximum supply-air temperature is controlled by a limit switch located in the gas section. The limit is designed to trip at 100 F above the maximum temperature rise. When the limit trips, 2 flashes occur on the IGC board. The gas valve is deenergized. After cooling, the system will reset and fires gas again. If four trips occur, the system shuts down into Lockout and 4 flashes occur on the IGC board. The system must then be manually reset by power down and power up of the unit. LIMIT SWITCH THERMISTOR (Staged Gas Unit Only) — The limit switch thermistor is a factory-installed component. It is located next to the lower limit switch. The limit switch thermistor senses temperature at limit switch location and prevents the limit from tripping while the unit is operating at low airflow. ROLLOUT SWITCH — This switch senses any flame or excessive heat in the main burner compartment and deenergizes the gas valve. If this occurs, the gas heating system is locked out (7 flashes on IGC board) until the rollout switch is reset manually. Reset rollout switch manually by powering down and powering up of the unit. When the rollout switch trips, it usually indicates a flue blockage. Inspect the unit for any obstruction in the flue system, for holes in the flue box, a defective hall effect sensor, a defective inducer motor, or a loose combustion blower. Compressor Removal — All compressors can be removed from the compressor side of the unit. IMPORTANT: All compressor mounting hardware and support brackets removed during servicing must be reinstalled prior to start-up. 1. Disconnect power to unit; lockout power to compressor. 2. Close suction and discharge service valves. 3. Relieve refrigerant pressure into a refrigerant recovery system. 4. Disconnect power wires at terminal box and disconnect conduit. 5. Disconnect wires from crankcase heater. 6. Lift compressor off mounting bolts and remove. Compressor Replacement — Perform the following: 1. Reverse procedure in Compressor Removal section. 2. Leak-check and evacuate system, recover refrigerant. 3. Recharge system per pre-start-up and start-up sequences. Recheck oil levels. 4. Energize crankcase heater for 24 hours prior to restart of system.
