Self-Contained Charging Procedures
Notice
The charge is critical on all Manitowoc ice machines. Use
a scale to ensure the proper charge is installed.
1. Be sure the ice machine is off.
2. Isolate the vacuum pump valve, low side and high
side access valves from the refrigeration system. The
refrigerant charging access valve remains open.
3. Open the refrigerant cylinder and add the proper
refrigerant charge (shown on nameplate) through the
liquid line drier.
,
Caution
Damage may occur when charging liquid into the front
discharge line access port.
Manitowoc replacement driers have a Schrader valve
built into the inlet of the drier. Filter driers without an
access port must be replaced with the current OEM part
before recharging the ice machine. All Liquid refrigerant
must be added through the liquid line drier access port.
4. Let the system “settle” for 2 to 3 minutes.
5. Isolate the refrigerant cylinder/charging hose from
the liquid line drier.
6. Press the On/Off button.
NOTE: Manifold gauge set must be removed properly to
ensure that no refrigerant contamination or loss occurs.
