When matching motor characteristics to compressor requirements, one should consider factors such as voltage, phase, and duty cycle. The motor’s rated horsepower should ideally be closely matched to the compressor’s demands to ensure optimal performance.
[pdf] Check for correct oil level at the ll plug location on the compressor. The oil level is full when oil is at the bottom of the threads in the ll plug hole. Check for oil purging from the air dryer. Refer to the image below as an example.
[pdf] The Positive Temperature Coefficient (PTC) thermistor causes the compressor “run” capacitor to be bypassed for a brief period of time at start up, creating extra starting torque in the compressor motor.
