DANGER !
Follow these directions exactly to avoid injury
to self or damage to pumping unit. Be careful
to keep inner and outer magnets at least (1)
foot apart until step 4. Do not engage magnets
in any other fashion.
1. Inspect magnets for any metal objects that may be
attached. Remove any foreign material. Locate the outer
magnet assembly per drawing (See Figure 13 on page
8). Apply Loctite to the set screw threads and tighten
both setscrews on to the motor or bearing carrier shaft.
The bearing carrier housing features a machined step
on its mounting flange, which is the reference point for
setting the position of the outer magnet.
2. Mount the bracket to the motor (or bearing carrier to
footed bracket) and secure with 4 capscrews (See
Figure 12 on page 7). Reach in and rotate magnets
by hand to make sure there is no interference. If
rubbing occurs, check the dimension. (See Figure 13
on page 8).
3. Slide the inner magnet assembly onto the pump shaft
(with key and inner retaining ring in place) and secure
CAUTION !
Do not place fingers near mounting surface to
avoid pinching (See Figure 9 on page 7).
5. Finish assembly by securing the pump to the bracket.
With power disconnected, check to see if the pump turns
over freely. This may be done by spinning the motor fan
blades or bearing carrier shaft. Use specified torque
below:
