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.
Installation of a Remote Condensing Unit may require
the use of special equipment for placement. Trained
and qualified personnel are required for proper
rigging and lifting.
The 60-month compressor warranty (including the 24-
month labor replacement warranty) will not apply if
the Manitowoc Ice Machine and remote Manitowoc
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.
