2-12 Part Number 000001530
Refrigeration System Installation
USAGE WITH NON-MANITOWOC
CONDENSING UNITS
Manitowoc CVD® Condensing Units are specifically
designed for usage with a QuietQube® Ice Machine
Head Section. Standard condensing units and Non-
Manitowoc condensing units will not operate a
QuietQube® Ice Machine Head Section.
Factory Equipment Refrigeration Amounts
ICE MACHINE HEAD SECTION
Each ice machine head section ships from the factory
with a R-404A refrigerant charge appropriate for the
installations with up to 50’ of refrigeration tubing. The
serial tag on the ice machine indicates the refrigerant
charge. For line set runs longer than 50’ 1 lb. of
additional refrigerant must be added for each 10’ of line
set run. The receiver is designed to hold a charge
sufficient to operate the ice machine in ambient
temperatures between -20°F (-28.9°C) and 120°F
(49°C), with line set lengths of up to 100 feet (30.5 m).
CVD® CONDENSING UNIT
Each condensing unit ships from the factory pressurized
with 50/50 nitrogen helium mixture that must be
removed during the installation process (approximately
20 psig).
REFRIGERATION LINE SETS/TRAP KIT
Refrigeration Rated Tubing and Trap Kits are shipped
capped with atmospheric pressure.

! Caution
The 60-month compressor warranty (including the
36-month labor replacement warranty) will not apply if
the Manitowoc Ice Machine and Manitowoc CVD
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, Inc.
! Warning
The ice machine head section contains the refrigerant
charge. Installation and brazing of the line sets must be
performed by a properly trained and EPA certified
refrigeration technician aware of the dangers of dealing
with refrigerant charged equipment.
! Caution
Never add more than nameplate charge to the
refrigeration system for any application.
! Warning
Installation of a QuietQube® Condensing Unit may require
the use of special equipment for placement. Trained and
qualified personnel are required for proper rigging and
lifting. Holes are provided on the corners of the condensing
unit to allow the use of lifting shackles.
