Rotation
- Check for correct motor rotation by jogging the motor. See “Unit Setup Adjustments” in
the Controller Operating and Service Manual. Compressor drive shaft rotation must be clockwise,
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
minimum rotation (less than one revolution if possible). Never allow motor to
reach full speed.
The compressor unit’s direction of rotation must be check every time the
compressor is reconnected to the power supply.

discharge pressure, set the controls to the desired load pressure. DO NOT EXCEED THE
MAXIMUM OPERATING PRESSURE ON THE COMPRESSOR NAMEPLATE. See “Operation
Adjustments” in the Controller Operating and Service Manual.
Operation at excessive discharge air pressure can cause personal injury or
damage to equipment. Do not adjust the full discharge air pressure above the
maximum stamped on the unit nameplate.
