Rotation
- Check for correct motor rotation by jogging the motor. See
“Unit Setup Adjustments” in

standing facing the compressor sheave.
Operation with incorrect motor rotation can damage equipment and cause oil
eruption from the compressor inlet. When checking motor rotation, induce

reach full speed.
The compressor unit’s direction of rotation must be checked every time the
compressor is reconnected to the power supply.
