Part No. 80-1100-3 7-5
Figure 7-5. Remote Automatic Shut-Off (Models Q450/Q600/Q800/Q1000)
Automatic Shut-Off
The compressor and liquid line solenoid valve are de-
energized simultaneously when the contactor contacts
open.
During the off cycle, the check valve prevents refrigerant
from migrating back into the high side, and the liquid line
solenoid prevents refrigerant from migrating back into
the low side. This protects the compressor from
refrigerant migration during the off cycle, preventing
refrigerant slugging upon start-up.
