Safety Information - Compu-aire System 2100 Series Installation And Operation Manual

CORRECT PHASING OF SCROLL COMPRESSORS:
The scroll compressor is a unidirectional compressor and will only compress refrigerant in one
rotation direction. Therefore, the proper rotation of the scroll compressor must be checked. The
scroll compressor will run in the reverse direction but it will not pump refrigerant and will draw
substantially reduced current as compared to listed values, and will result in elevated sound levels.
Scroll compressor will trip on internal protection after running for some time in the reverse
direction.
Verification of the proper rotation of the scroll compressor is done by observing that suction
pressure drops and discharge pressure rises when the compressor is energized.
WARNING:
EXTENDED IMPROPER OPERATION MAY ALSO VOID COMPRESSOR WARRANTY.
