Motor Pulley
1.
The motor pulley should be installed on the motor shaft with the threaded side out.
2.
Align the motor pulley with the blower pulley.
3.
Tighten the set screw A (5/32 hex screw) opposite the threaded side to secure the pulley to
the shaft. Be sure to tighten the set screw onto the flat side of the shaft.
4.
Loosen set screw B (5/32 hex screw) on the threaded side of the pulley. This will enable the
outside jaw of the pulley to rotate.
5.
Turn the outside jaw clockwise until the pulley is fully closed, then turn the ‘outside jaw’
counter-clockwise until the set screw is positioned over the nearest flat spot.
6.
From the closed position, open the pulley (turn outside jaw counter-clockwise) 3 turns.
Tighten the set screw. It is important that the set screw is not tightened onto the threads.
This will damage the pulley.
7.
After the unit is fully installed, with the fan on HI speed, the pump off and all the louvers in
place, check the motor amperage using an ammeter. The amperage should read what the manufacturer recommends on the motor
name plate. If this is not the case, adjust the amperage by closing (increase amperage) or opening (decrease amperage) the pulley
½ turn. Recheck amperage after each adjustment.
To prevent motor damage, never exceed the amperage listed on the motor.
