IMPORTANT NOTES:
1.To find the charge adjustment and system charge for any evaporator and tubing length: Line Adjustment = (Line Charge/FT) x Line Length
System Total = Factory Charge + Line Adjustment
2.Round to the nearest ounce and allow for gauges and hoses.
FIELD CHARGING
The use of the superheat method is highly recommended for field charging or checking the existing refrigerant charge in a system. Because each installation is different in terms of indoor air flow, refrigerant line length, etc.., the factory charge may not be correct for every application. To assure the best perfor- mance from the
For proper superheat readings, a standard

The S2HA has manifold access points on each of the service valves for the high and low pressures in cooling mode. There is an additional “common suction” access point above each service valve set to provide low pressure access in the heating mode as both service valves are at high side pressure.
