Remote Ice Machine Usage with Non-
Manitowoc Multi-Circuit Condensers
Warranty
The sixty (60) month compressor warranty, including thirty
six (36) month labor replacement warranty, shall not apply
when the remote ice machine is not installed within the
remote specifications. The foregoing warranty shall not
apply to any ice machine installed and/or maintained
inconsistent with the technical instructions provided
by Manitowoc Ice. Performance may vary from Sales
specifications. ARI certified standard ratings only apply
when used with a Manitowoc remote condenser.
If the design of the condenser meets the specifications,
Manitowoc’s only approval is for full warranty coverage
to be extended to the Manitowoc manufactured part of
the system. Since Manitowoc does not test the condenser
in conjunction with the ice machine, Manitowoc will not
endorse, recommend, or approve the condenser, and will
not be responsible for its performance or reliability.
Important
Manitowoc warrants only complete new and unused
remote packages. Guaranteeing the integrity of a new
ice machine under the terms of our warranty prohibits
the use of pre-existing (used) tubing or condensers.
