Part Number 000002688 2-13
Refrigeration System Installation
(QF2300/RFC2385 ONLY)
USAGE WITH NON-MANITOWOC
CONDENSING UNITS
Manitowoc Condensing Units are specifically designed
for usage with a Manitowoc Flake/Chiplet Ice Machine
Head Sections. Manitowoc Flake/Chiplet Ice Machines
will not operate with non-Manitowoc condensing units.
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 line
sets up to 50’ in length (12.5 lbs.). The serial tag on the
ice machine indicates the refrigerant charge. Additional
refrigerant must be added for line set lengths between
50’ and 100’ (1.5 lbs.) see chart below.
REMOTE 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/TRAPS KIT
Refrigeration Rated Tubing and Trap Kits are shipped
capped with atmospheric pressure.
