Refrigerant Recovery/Evacuation
Do not purge refrigerant to the atmosphere. Capture
refrigerant using recovery equipment. Follow the
manufacturer’s recommendations.
Manitowoc Ice assumes no responsibility for the use
of contaminated refrigerant. Damage resulting from
the use of contaminated refrigerant is the sole
responsibility of the servicing company.
Replace the liquid line drier before evacuating and
recharging. Use only a Manitowoc (OEM) liquid line
filter-drier to prevent voiding the warranty.
Recovery/evacuation of a QuietQube
®
remote
system requires connections at either three or five
points for complete system recovery/evacuation.
Check valves are located in the ice machine head
section on all models and in the CVD condensing
unit on models manufactured in 2010 and beyond.
Three point connections are - receiver service valve,
suction line and liquid line - Five point requires
another connection between the compressor and
suction filter access valves to recover and evacuate
the entire system.
The receiver access valve (located in the ice
machine head section) must be accessed during
refrigerant recovery to allow complete removal of the
refrigerant charge.
