SPLIT SYSTEM HEATING PERFORMANCE
High pressure is measured at the suction service valve ( the larger valve).
AMPS = Outdoor unit amps (comp.+fan)
Low pressure is measured at the gauge port connection.
KW = Total system power
Calculations are based on nominal CFM and 70 °F indoor dry bulb.
*Note: Shaded area is AHRI Rating Conditions at 47° outdoor ambient temberature
