Charging Procedures
IMPORTANT
The charge is critical on all Manitowoc ice machines. Use a scale to ensure the proper charge is installed. A quick disconnect is required for the high side connection
1.Be sure the toggle switch is in the OFF position.
2.Close the vacuum pump valve and the low side manifold gauge valve.
3.Open the high side manifold gauge valve.
4.Using a digital scale add the proper refrigerant charge (shown on nameplate) through the high side.
5.Close/isolate the refrigerant cylinder.
6.Let the system “settle” for 2 to 3 minutes.
7.Place the toggle switch in the ICE position.
8.Close the high side on the manifold gauge set.
NOTE: Manifold gauges must be removed properly to ensure that no refrigerant contamination or loss occurs. A quick disconnect is required for the high side connection.
