Fit the plug (3) again.
Note
This assembly and operating instructions only describe action steps related to the motor. You should also
observe the pump unit manufacturer's instructions in all events.
Short motor cable fitted (see 5.3.1)
Shaft protector removed
Motor shaft rotated manually before assembly runs freely after overcoming static friction
Surfaces of parts to be connected are free from dust and dirt
Coupling attached to the pump shaft, slides on the motor shaft

Motor damage due to damaged motor cable!
Make sure that the motor cable is not in contact with any sharp edges.
Protect the cable against damage using the cable guard.
Encapsulated Submersible Motors
Top up or drain motor fluid.
Apply the filling syringe (5) to the filling valve.
Top up the motor filling fluid until the value of
the diaphragm position is lower than the target
value.
Apply water-resistant, FDA approved, approvacid-free
grease (e.g. Mobil FM 102, Texaco Cygnus) to the
inner part of the coupling to the pump unit.
Make sure that the splined section is encased by an O-
ring when the motor and the pump unit are assembled
together.
Align the pump unit and motor shaft to each other,
connect the pump unit and the motor.
Screw the motor to the pump unit, tighten the fixing
screws crosswise as instructed.
6": ½"-20 UNF-2B
8": Bore 17.5 mm
