b. Insert the motor key and lightly tighten the setscrew using a 2.5mm hex key until it
cannot fall out.
For
three phase motors, use the motor key that came inside the box with the taper-
lock bushing. If there was a key taped to the motor, do not use it.
a. For One Phase motors, lift the impeller so that the bushing is flush with the top of the
motor shaft.
b. For Three Phase motors, lift the impeller so that the bushing sits ¼” below the top of the
motor shaft.
4. Tighten the taper-lock bolts:
a. Consecutively tighten each taper-lock bolt with a 4
mm hex key by a ¼ revolution, until they are all tight.
The tightening of each bolt will cause the
subsequent bolts to feel as if they have loosened.
b.
Repeat this process until each bolt is as tight as
possible, without over-torqueing the bolt.
Upon completion, there should be a minimum of ¼”
clearance between the back of the impeller and the
motor bolts intalled in the motor plate. There also may
be up to a
