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.
Kits are available for head pressure control
installation:
• R404A Refrigerant - K00479
• R410A Refrigerant - K00221
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.
