To inspect rotors rotation, pull out the “EMERGENCY STOP” button and press once,
quickly press the “START” and “STOP” button in sequence, allowing the motor to turn 2
or 3 revolutions. Observe the drive shaft for correct direction. If reverse rotation is observed,
disconnect the power supply, reverse power input leads at the motor starter. Recheck for
proper rotation.
4.7 FAN ROTATION INSPECTION
Fan motor rotation should be inspected. KRSD compressors use an axial fan for cooling.
Fan rotation is inspected through an arrow shaped observation hole above the fan motor.
The fan must rotate in the direction indicated by the arrow.
NOTICE!
Always inspect fan rotation through the observation hole. Never assume the fan
rotation is correct based on the induced air flow across the coolers. A centrifugal
fan can pull the airflow across the coolers when rotating in either direction;
however, incorrect rotation will cause high discharge temperature.
