Failure to properly ground the compressor package could result in controller
malfunction.

V-Belt System
- Refer to Section 8 for detailed instruction to unpack and check the alignment of the
belt system.
The motor jacking hardware must be re-configured, the main motor carrier
bracket removed, belts engaged, and the belt sheaves alignment checked prior to
compressor operation. Failure to do so will prevent compressor operation and/or
component damage.
9.
Rotation
- Check for correct motor rotation by, in quick succession, starting and stopping the
compressor system. Note that the controller can also detect reverse motor rotation by sensing a
vacuum pressure, but this may damage the compressor by prolonged operation under reverse
rotation. If motor reverse rotation is c
onfirmed, follow the appropriate “lockout/tagout” procedure to
isolate the package from the electrical grid, reverse any two motor leads connected to the package
or motor, restore electrical power to the package, and re-check rotation.
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 checked every time the
compressor package or its main motor is reconnected to the power supply.
Electrical shock can cause injury or death. Open main disconnect switch,
lockout and tagout before working on control box.
