Installation Section 2
Design & Burst Pressure
Design Pressure 600 psig - 4137 kPa
Burst Pressure 2500 psig - 17237 kPa
Head Pressure Control Valve
Do not use a fan cycling control to try to
maintain discharge pressure. Compressor
failure will result. Any remote condenser
connected to a Manitowoc Ice Machine
must have the OEM head pressure control
valve installed. 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. Do not exceed
internal volume and try to add charge to
compensate, as compressor failure will
result.

Refrigerant Charge
The ice machine model/serial tag lists the
refrigerant amount. Remote condensers
and line sets contain a vapor charge only.
Model Amount Type
IT0500N 6.0 lbs - 2.72 kg R410A
IF0600N *6.5 lbs - 2.95 kg R404A
IF0900N *7 lbs - 3.18 kg R404A
IT1200N 7.5 lbs - 3.40 kg R410A
IT1500N 8.0 lbs - 3.63 kg R410A
IT1900N 8.0 lbs - 3.63 kg R410A
*Data marked with an asterisk is preliminary and subject to change - Model/serial
plate information overrides all data listed in this chart.
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 K00129)
be installed in the multi-circuit condenser,
and that a vapor “holding” charge, 5 oz.
(150 ml), of proper refrigerant be added to
the condenser prior to connection of the
ice machine or line set to the condenser.
