Table 3. Q4SA Cooling Charging Charts

Heat Pump in Cooling

* Note: All pressures are listed in

psig. and all temperatures in deg. F.

— Shaded Boxes indicate flooded conditions

— Rated Design Values. Suction Pressure will be lower than design value if indoor air

flow, entering dry bulb, or entering wet bulb temperatures are lower than design.

— Discharge temperatures greater than charted values indicates a refrigerant

undercharge.
