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.
