Operation

1. Before starting up or operating fan, check all

fasteners for tightness. In particular, check the

setscrews in wheel hub and pulleys.

2. While in the OFF position or before connecting the

fan to power, turn the fan wheel by hand to be sure it

is not striking the venturi or any obstacle.

3. Start the fan and shut it off immediately to check

rotation of the wheel with directional arrow in the

motor compartment. See Figure 9 on page 6.

4. When the fan is started, observe the operation and

check for any unusual noises.

5. With the system in full operation and all ductwork

attached, measure current input to the motor and

compare with the nameplate rating to determine if

the motor is operating under safe load conditions.

6. Keep inlets and approaches to fan clean and free

from obstruction.

IMPORTANT

Adjust (tighten) belt tension after the first 24-48 hours

of operation.
