*Optimum performance point, 95_F(35_C) outdoor ambient and (80_F/27_C dry bulb), (67_F/19_C wet bulb) indoor conditions. (DOE A Test Conditions)
Where a dash (--- --- ) appears do not attempt to charge system under these conditions or refrigerant slugging may occur. Charge must be weighed in.
Note: Superheat _F is at low--- side service port, Allow a tolerance of ±3_F(±1.7_C)
Note: Indoor dry bulb between 70_Fand80_F(21_Cand27_C)
