Step 1 Check the Voltage
Before starting the unit, compare the supplied voltage, hertz, and phase with the unit and motor’s nameplate
information.
Step 2 Check the Blower Rotation
Open the blower access door and run the blower momentarily to determine the rotation. Arrows are placed on
the blower scroll to indicate the proper direction.
IMPORTANT!
If the blower is rotating in the wrong direction, the unit will move some air, but will not perform as
designed. Be sure to perform a visual inspection to guarantee the correct blower rotation.

Pre Start-Up Check
Rotate the fan wheel by hand and make sure no parts
are rubbing. Check the V-belt drive for proper
alignment and tension (a guide for proper belt tension
and alignment is provided in the belt maintenance
section). Check fasteners, set screws and locking
collars on the fan, bearings, drive, motor base and
accessories for tightness. Remove any shipping
fasteners from the blower vibration isolators.
NOTE!
To reverse the rotation on three phase units, disconnect and lock-out the power, then interchange any
two power leads.
NOTE!
To reverse the rotation on single phase units, disconnect and lock-out the power, then rewire the
motor per the manufacturer’s instructions.
