DANGER !
follow these directions exactly to avoid injury
to self or damage to the pumping unit. Be care-
ful to keep inner and outer magnets at least (1)
foot apart until step 4. Do not engage magnets
in any other fashion.
1. Inspect the magnets for any steel objects, which may
be attached. Remove any foreign material. Locate the
outer magnet assembly per dimension (See Figure 22).
Apply Loctite and tighten the setscrews onto the motor
or bearing carrier key and shaft.
2. If the bracket is not fastened to a base, clamp it down.
Mount the motor or bearing carrier to the bracket. Reach
in and rotate the magnets by hand to make sure there is
no interference. If rubbing occurs check the dimension
in Figure 22 or contact the factory.
3. Check to make sure pump rotates freely by turning
inner magnet assembly. Inspect magnet to make sure
it has not picked up any foreign particles, which could
damage the pump. Make sure the canister O-ring is in
good condition and in place. Place canister onto pump
and press on until canister is in contact with pump
mounting flange.
4. Use a fully threaded M10X120mm capscrew to control
assembling the pump. Thread completely into bracket as
shown in Figure 23. Support pump with overhead hoist
if possible while guiding canister into bracket opening.
Back capscrew off while guiding the pump being careful
that end of capscrew is positioned in counterbore hole of
casing flange. Mount pump with (4) 12mm capscrews.
CAUTION !
Do not place fingers onto front of pump mount-
ing flange. Align canister into bore of bracket
and gently slide in. When magnets start to en-
gage, the unit will finish engagement on its own
very rapidly unless the M10x120mm capscrew
is properly used. Make sure fingers are not on
the front of the pump. See figure 23.
DANGER!
Be certain that the driving means (motor, tur-
bine, engine, etc.) has been “locked out” or
made non-operational so that it cannot be
started while work is being done on pump.
5. Be certain that the power supply to the pump is “Locked-
out”. Finish assembly by securing the pump to the
bracket. See Figure 23. Check that pump rotates freely
by spinning the motor fan blades or the bearing carrier
shaft.
