Each ice machine condensing unit ships from the factory
Line Set*
with a R-404A refrigerant charge appropriate for the
entire system operation. The serial tag on the ice
RC-21
machine indicates the refrigerant charge. The refrigerant
RC-31
charge is sufficient to operate the ice machine in
RC-51
ambient temperatures between -20°F (-28.9°C) and
120°F (48.9°C). With line set lengths of up to 100 feet
(30.5 m).
Liquid Line
3/8 inch
(9.5 mm)
The QuietQube Condensing Unit 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.
Never add more than nameplate charge to the
refrigeration system for any application.
REFRIGERATION LINE SETS/TRAP KIT
Refrigeration Rated Tubing and Trap Kits are shipped
capped with atmospheric pressure.
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.
