9.1A 9.0A 9.1A
With compressor and condenser fan on, compressor is
operating at 100 percent capacity. Amp draw is
measured and compared to voltage. Compressor
amperes are recorded in PTI log.
Suction pressure sensor must read a decreasing signal
at min 0.15 bars (2.175 psi).
Discharge pressure sensor must read an increasing
signal of min 0.15 bars (2.175 psi).
