Service Manual

Part Number: 000015430 Rev 02 5/20 35
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.
