In case the main motor or any of the axial fan/motor combinations are replaced or disconnected
from the package wiring system, their rotation must be verified. If the incorrect rotation is noted
on any one electric motor, take the following steps to make the necessary correction:
·
Disconnect, lockout and tagout power supply to the compressor package.
·
Locate, within the electrical enclosure, the three (3) wires feeding power to the motor in
question.
·
Loosen, reverse, and re-fasten the connections of any two (2) of the wires.
·
Re-energize compressor package and recheck 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 is reconnected to the power supply.
The radial fan/motor combinations are integrated, and the incoming electrical
power connections do not affect their rotation. If reverse rotation is noted for
either radial fan, please notify Gardner Denver for corrective action.
