When charging is complete, close the valve on the refrigerant manifold set and close the service
valve on the refrigerant tank. Then go back into menu “H. Calibrate Sensors” and set either the
“Return Air Temp Sensor” or “Discharge Air Temp Sensor” menu oset values back to 0. If a cali-
bration oset value has been determined in the eld that is dierent from 0 bring the oset num-
ber back to this value.
5.5 Flooded System Charging
WARNING: The constant speed compressor must be charged before charg-
ing the variable speed compressor in a dual circuit system.
Flooded systems are supplied with optional liquid receiver and head pressure control valve. When
the ambient temperature falls during cold weather, the head pressure control valve will regulate the
ow of refrigerant to ensure minimum receiver pressure. The condenser is partially ooded with liquid
refrigerant in cold weather. In warm weather the extra refrigerant is stored in the receiver. Therefore,
ooded systems require more refrigerant than fan speed control systems.

See the tables for the appropriate charging
1. After the system has been properly evacuated. Calculate the proper charge by following
the steps of the tables below.
