* Note: All pressures are listed in psig. and all temperatures in °F.
- 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 an undercharged system.
Pressures shown are for heat pump operating only without back-up heat.
