Important

Manitowoc remote systems are only approved and 

warranted as a complete new package. Warranty on the 

refrigeration system will be void if a new ice machine 

head section is connected to pre-existing (used) tubing or 

condensing units or vice versa.

USAGE WITH NON-MANITOWOC CONDENSING UNITS

Manitowoc Remote Condensing Units are specifically 

designed for usage with a QuietQube® Ice Machine Head 

Section. Standard condensing units and Non-Manitowoc 

condensing units are not approved for use with a 

QuietQube® Ice Machine Head Section.

,

Caution

The 60-month compressor warranty (including the 

36-month labor replacement warranty) will not 

apply if the Manitowoc Ice Machine and Manitowoc 

Remote Condensing Unit are not installed according 

to specifications. This warranty also will not apply if 

the refrigeration system is modified with a condenser, 

heat reclaim device, or other parts or assemblies not 

manufactured by Manitowoc Ice.

Factory Equipment Refrigeration Amounts

ICE MACHINE HEAD SECTION
Each ice machine condensing unit ships from the factory 

with a R-404A refrigerant charge appropriate for the entire 

system operation. The serial tag on the ice machine indicates 

the refrigerant charge. The refrigerant charge is sufficient to 

operate the ice machine in ambient temperatures between 

-29°C and 4.9°C. With line set lengths of up to 30.5 m.
REFRIGERATION LINE SETS/TRAP KIT
Refrigeration Rated Tubing and Trap Kits are shipped capped 

with atmospheric pressure.
