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. Non-Manitowoc condensing units will not
operate a QuietQube® Ice Machine Head Section.
SU1000C/Servend UC-300 Dispenser
Refrigeration system installation must meet the
requirements and follow the procedures listed in this
section.

SU1000C/Q1400C
Each ice machine head section 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 -20°F (-28.9°C) and
130°F (54.4°C)*. With line set lengths of up to 100 feet
(30.5 m).
*CVD1476: -50°F to 110°F (-46°C to 43°C)
QDUALC
Each QDUALC ice machine head section ships from the
factory with an R-404A refrigerant charge appropriate for
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).

! 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.
! 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.
!
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.
