Fluid Level; Compressor Rotation; Fan Rotation - Quincy QSF Series Instruction Manual

Fluid Level

The compressor is filled at the factory with the correct amount of fluid. A fluid tag is provided with the
information concerning the initial fill of fluid. Fluid level is monitored by sight glass while in operation.
Fluid level should be between the maximum and minimum level while in operation. DO NOT OVER
FILL. The fluid level should be maintained in the run zone.

Compressor Rotation

The compressor rotation must be checked prior to start-up. Proper rotation is counter-clockwise as
viewed from the power-input end. The power-input end of the compressor is marked with an arrow
noting the proper rotation. Failure to operate the compressor in correct rotation will result in extreme
damage to the compressor and warranty coverage will be voided. Briefly jog the starter button allowing
the motor to turn 2 or 3 revolutions. Observe the drive element for correct direction. If incorrect
rotation is observed, lock out power supply, reverse electrical leads L
check for correct rotation.
NOTE:
Operating more than one second in reverse rotation may cause damage to the airend.
Fan Rotation (Air-cooled only)
After checking the compressor rotation, also check the fan rotation. Fan airflow should be outward, that
is, pushing the air through the coolers.
