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.
HEATING PERFORMANCE DATA
*Note: Shaded area is AHRI Rating Conditions at 47° outdoor ambient temperature
PERFORMANCE TEST
All data based upon listed indoor dry bulb temperature. .00 inches exter-
nal static pressure on coil of outdoor section. Indoor air cubic feet per
minute (CFM) as listed in the Performance Data Sheets:
If conditions vary from this, results will change as follows:
1. As indoor dry bulb temperatures increase, a slight increase will
occur in indoor air temperature drop (Delta T). Low and high side
pressures and power will not change.
2. As indoor CFM decreases, a slight increase will occur in indoor
temperature drop (Delta T). A slight decrease will occur in low and
high side pressures and power.
A properly operating unit should be within plus or minus 2 degrees of
the subcooling value shown in the Heat Pump Specifications.
A properly operating unit should be within plus or minus 3 degrees of
the typical (Delta T) value shown.
A properly operating unit should be within plus or minus 7 PSIG of the HI
PR shown.
A properly operating unit should be within plus or minus 3 PSIG of the LO
PR shown.
A properly operating unit should be within plus or minus 3 Amps of the
typical value shown.
