Electrical – Single-Phase Motors
Clear Vue Cyclones highly recommends the use of a professional,
licensed electrician to complete the wiring and any electrical work
associated with this installation. Significant damage to your system and/or
bodily harm can result.
The Leeson 5HP motor is designed to rotate either clockwise or counter-clockwise. Motors
are prewired direct from Leeson and may be wired for either rotation. You will need to
check the wiring to ensure it is correct.
Please also refer to the assembly sheet provided with the Electrical Box.
1. Follow the directions on the Leeson motor for wiring the motor for a clockwise rotation:
a. Connect
L1
to
P1
.
b. Connect
L2
to both
T4
&
T8
.
c. Connect
P3
&
T1
&
T5
– wire together and cap off with a wire lug.
d. Connect the ground wire (bare wire) to the green screw inside the motor connection
box.
Leeson recommends the use of wire lugs in lieu of wire nuts to secure all connections.
Leeson defines motor rotation with the motor shaft facing away. For our installation
puposes, rotation is defined from the opposite end of the motor. In order to obtain a
counter-clockwise rotation when veiwed from below, please follow the clockwise
instructions on Leeson’s motor plate, which match step 1 above.
Once the motor is wired, it is important to verify the rotation of the impeller. Disconnect the
flex hose attached to the Blower Housing exhasut to check rotation. From this vantage point,
the impeller should be rotating from the back of the Blower Housing towards the front.
Note that our impellers are backward inclined, allowing our system to move high volumes of
air at a variety of static pressures. Each blade on the impeller has a slight “C” shape. When
rotating correctly, the convex side of the blade will be hitting the air first.
