Final Installation Steps
a. Inspect fasteners and setscrews, particularly fan
mounting and bearing fasteners, and tighten according
to the recommended torque shown in the table below,
Recommended Torque for Setscrews/Bolts.
b. Inspect for correct voltage with voltmeter.
c. Ensure all accessories are installed.
d. Test the fan to be sure the rotation is the same as indi-
cated by the arrow marked Rotation.
Do not allow the fan to run in the wrong direction.
This will overheat the motor and cause serious dam-
age. For 3-phase motors, if the fan is running in the
wrong direction, check the control switch. It is possi-
ble to interchange two leads at this location so that the
fan is operating in the correct direction.
Operation
Pre-Start Checks
a. Lock out all the primary and secondary power sources.
b. Inspect fasteners and setscrews, particularly those
used for mounting the unit, and tighten if necessary.
c. Inspect belt tension and pulley alignment. (Remember,
if belt tension is correct, a loud squeal occurs as the
fan increases to full power.)
d. Inspect motor wiring.
e. Ensure the belt touches only the pulleys.
f. Rotate the propeller to ensure it does not rub against
the base.
g. Ensure fan and ductwork are clean and free of debris.
h. Test the fan to ensure the rotation of the propeller is
the same as indicated by the rotation label. (The SEP
has a reversible propeller and can be operated in either
direction)
i. Restore power to unit.
Wiring Diagrams
When ground is required, attach to ground A or B with no. 6 thread forming
screw. To reverse, interchange T-1 and T-4.
Single Speed, Single Phase Motor
To reverse, interchange any 2 line leads.
When ground required, attach to ground A or B with No. 6 thread forming
screw. To reverse, interchange T-1 and T-4 leads.
2 Speed, 2 Winding, Single Phase Motor 2 Speed, 1 Winding, 3 Phase Motor
To reverse, interchange any 2 line leads. Motors require magnetic control.
Single Speed, Single Phase, Dual Voltage 2 Speed, 2 Winding, 3 Phase
To reverse: High Speed-interchange leads T
11
and T
12
.
Low Speed-interchange leads T
1
and T
2
. Both Speeds-interchange any 2
line leads.
For 3 phase, damper motor
voltage should be the same
between L
1
and L
2
. For sin-
gle phase application, disre-
gard L
3
. *Damper motors
may be available in 115, 230
and 460 volt models. The
damper motor nameplate
voltage should be verified
prior to connection. ** A
transformer may be provided
in some installations to cor-
rect the damper motor volt-
age to the specified voltage.
