System Charge Adjustment
Table 28. Temperature Measurements
Check the outdoor temperatures.
Subcooling using “Charging Mode-Cooling” is the only
recommended method of charging between 55 ° F and 120° F ambient
outdoor temperature.
For best results the indoor temperature should be kept between 70° F
to 80° F.
Table 29. Subcooling Charging Corrections
Determine the final subcooling value using total Line Length and Lift
measured in Table 8, p. 9— (Required Refrigerant Line Length) and
the Subcooling Charging Corrections Charts.
