System Charge Adjustment
Table 24. Temperature Measurements (Systems can be rated with TXV, EEV or Piston. Ensure charging method is
correct).
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.
Note: For Superheat (In Cooling Mode), refer to the Superheat
Charging Table
120° F
55° F
For best results the indoor temperature should be kept between 70° F
to 80° F.
