REFRIGERATION SYSTEM
FUNCTIONALITY (Continued)
During defrost mode, the defrost solenoid
valve (HGSV) is energized and held open
allowing the gas to be redirected through the
evaporator inlet. The evaporator is split and
circuited for 2 refrigeration circuits.
Defrost cycle is temperature-terminated with
a failsafe that is 50 minutes. Normally only 3
defrost per day are required.
