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, Inc. Performance may vary
from Sales specifications. S-Model 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.
HEAD PRESSURE CONTROL VALVE
Any remote condenser connected to a Manitowoc S-
Model Ice Machine must have a head pressure control
valve #836809-3 (available from Manitowoc Distributors)
installed on the condenser package. Manitowoc will not
accept substitute “off the shelf” head pressure control
valves.
FAN MOTOR
The condenser fan must be on during the complete ice
machine freeze cycle (do not cycle on fan cycle control).
The ice maker has a condenser fan motor circuit for use
with a Manitowoc condenser. It is recommended that this
circuit be used to control the condenser fan(s) on the
multi-circuit condenser to assure it is on at the proper
time. Do not exceed the rated amps for the fan motor
circuit listed on the ice machine’s serial tag.
INTERNAL CONDENSER VOLUME
The multi-circuit condenser internal volume must not be
less than or exceed that used by Manitowoc (see chart
on next page). Do not exceed internal volume and try
to add charge to compensate, as compressor failure
will result.
CONDENSER ∆T
∆T is the difference in temperature between the
condensing refrigerant and entering air. The ∆T should
be 15 to 20°F (-9.4 to -6.6°C) at the beginning of the
freeze cycle (peak load conditions) and drop down to 12
to 17°F (-11.1 to -8.3°C) during the last 75% of the
freeze cycle (average load conditions).
REFRIGERANT CHARGE
Remote ice machines have the serial plate refrigerant
charge (total system charge) located in the ice maker
section. (Remote condensers and line sets are supplied
with only a vapor charge.)
QUICK CONNECT FITTINGS
The ice machine and line sets come with quick connect
fittings. It is recommended that matching quick connects
(available through Manitowoc Distributors) be installed in
the multi-circuit condenser, and that a vapor “holding”
charge (5 oz.) of proper refrigerant be added to the
condenser prior to connection of the ice machine or line
set to the condenser.
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.
!
Caution
Do not use a fan cycling control to try to maintain
discharge pressure. Compressor failure will result.
!
Caution
Never add more than nameplate charge to ice
machine for any application.
