Recovery/Evacuation/Charging Procedures
QuietQube® Models
Do not purge refrigerant to the atmosphere. Capture
refrigerant using recovery equipment. Follow the
manufacturer’s recommendations.
Notice
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.
Notice
Replace the liquid line drier after recovering the
refrigerant and before evacuating and recharging.
Use only a Manitowoc (OEM) liquid line filter-drier to
prevent voiding the warranty.
Notice
Recovery/evacuation of a QuietQube® remote
system requires connections at either 4 or 5
recovery points for complete system recovery/
evacuation. Check valves are located in the ice
machine head section and the CVD condensing unit.
Five point requires connections between the
compressor and suction filter access valve, receiver
access valve and the high and low side access
valves on the front or rear of the ice machine.
Four point is required on units that do not have a
receiver service valve.
Notice
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.
