REFRIGERANT CHARGING CHARTS FOR
COOLING MODE OF OPERATION
NOTE: The Refrigerant Charging Charts are applicable to
matched assemblies of our equipment and at listed airflows
for the indoor coil. Assemblies of indoor coils and outdoor
units not listed are not recommended and deviations from
rated airflows or non-listed equipment combinations may
require modifications to the expansion device(s) and
refrigerant charging procedures for proper and efficient
system operation.
Refrigerant Charging Chart — Refer to Refrigerant
Charging Charts for correct system charging and to Orifice
Usage Chart for correct restrictor sizes.
Optional Equipment — A functional checkout should be
performed in specific accordance with the checkout
procedures supplied with the equipment.

* Note: All pressures are listed in psig. and all temperatures in degrees 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 indicate a
refrigerant undercharge.
