Compressor HVAC: Service Precautions

Do not strike, drop, or turn the compressor upside down. If the compressor is knocked over or turned upside down, rotate the compressor's clutch at least 6 times by hand in order to circulate the oil which has settled in the cylinder. Sudden rotation with oil in the cylinder will cause damage and adversely affect durability.
