*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.

REFRIGERANT CHARGING CHART Heating Mode of Operation

PROCEDURE FOR CHARGING 10-TON HEAT PUMP IN HEATING MODE.

1.Evacuate the refrigerant system.

2.Charge the system by weighing in 30 lbs R-22 refrigerant. This is the recommended charge for 5/8 inch 15 foot line set.

For line sets other than 15 feet add 9.0 oz. R-22 per additional 5 feet of 5/8 inch liquid line over 15 feet and remove 9.0 oz per 5 feet less than 15 feet of liquid line.

3.Ensure that the unit is operating properly per the heating functional checkout in these installation instructions.
