Specs At A Glance

Good To Know

Q: Does this compressor require specific oil before installation? A: It is necessary to verify the oil type and quantity required by the system, as compressors may ship with limited assembly lubricant only.

Q: What causes a compressor to fail prematurely? A: Contaminants in the refrigerant lines or a faulty expansion valve often lead to increased pressure and mechanical failure of the unit.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
