NOTE:
7.0 SYSTEM OPERATION
7.1 COMPRESSOR CRANKCASE HEATER (CCH) (Heat pump only,
optional
)
Refrigerant migration during the off cycle can result in a noisy start up. Add a crankcase
heater to minimize refrigeration migration, and to help eliminate any start up noise or
bearing “wash out”.
All heaters must be located on the lower half of the compressor shell. Its purpose is to
drive refrigerant from the compressor shell during long off cycles, thus preventing
damage to the compressor during start-up.
The crankcase heating start condition:
1.The crankcase heating start must meet two conditions:
A. Outdoor temperature
＜
37.4° F.
B. Compressor stops working more than 3 hours.
2. Outdoor temperature
＜ 37.4° F and just connected to the power source.
The crankcase heating stop must meet condition:
Outdoor temperature ＞ 44.6° F or compressor start.
7.2 REVERSING VALVE INTRODUCTION (Heat pump only)
Reversing valve energizes at the heating conditions, and cut off at the cooling condition.
At initial start-up or after extended shutdown periods, make sure the heater is energized
for at least 12 hours before the compressor is started. (Disconnect switch on and wall
thermostat off.)
