Unpacking

Check that the delivery is complete and undamaged. Any dam-
age that is detected should be confirmed on the original con-
signment note and reported to us immediately.
Risk of injury
• To avoid damage, remove the motor from the
packaging carefully.
• Pay attention to weight and centre of gravity.
• Only use suitable lifting tackle with sufficient carry-
ing capacity.
• Do not move under suspended loads.
• Protect the motor cable from mechanical damage.
3.4

Initial checks

After unpacking, check for any external damage, for example
• on the underside of the housing
• on the housing (stator)
• on the upper and lower housing cover (motor bearing)
• on the connecting or control cable
If you detect any damage, you may not install the
motor or put it into operation. Damaged motors rep-
resent a risk of injury or death.

4. Installing the motor

4.1

Required tools

You will need the following tools and instruments to carry out
the necessary checks and to install the motor properly:
• An insulation resistance meter with 500 volts test voltage or
5000 volts test voltage for high-voltage motors with more than
3000 volts of operating voltage. Display up to at least 200
MOhm.
• Suitable tools for filling and assembling the motor (container
for water, funnel, spanner, torque wrench, etc.).
4.2

Filling the motor

• Before installation, the motor must be filled with clean
drinking water (not distilled water)!
• If the motor was supplied with a motor filling or already
filled for storage, then the motor filling must be checked
before installation. If the check shows that there is no
motor fluid, then you can top it up with clean drinking
water (not distilled water).
• Please fill with water with a pH value between 7 and 7.5, and
from 7 to 8 hardness according to the German scale, 10-
20mg/l nitrates. There must be no particulates or sand. Suit-
able instruments are available on request.
• Before they can be used in drinking water, motors that have
been preserved and/or filled with antifreeze must be emptied,
rinsed, cleaned and then filled again with clean drinking wa-
ter.
4.2.1 Filling with motor fluid
Risk of injury!
Ensure that motor cannot fall over during this proce-
dure.
• Place the motor in the vertical position.
• The motor must always be filled in the vertical position!
• Remove screw plug from the filling and venting hole.
• Insert funnel (angled funnel) into the filling hole.
• Using the funnel, fill the motor with unpressured water until
water flows out of the filling opening.
• Wait 2 hours, then check the fill level again. Continue the fill-
ing process until the water in the filling and venting opening
remains constant and without bubbles.
• Re-tighten the screw plugs and seals.
4.3

Assembling the motor and pump assembly

Never use the motor with a damaged pump or
components. Otherwise, the high driving force
may lead to accidents. There is a risk of injury or
death!
4.3.1 Preparatory checks
• If necessary, remove the shaft protection.
• Before assembly, turn the motor shaft by hand or using an
auxiliary tool. To avoid mechanical damage to the shaft, only
suitable auxiliary tools may be used. The shaft must move
freely after overcoming the static friction. If it does not, the
cause must be determined.
• Please ensure that the surfaces of the parts to be connected
are free of dirt and dust.
4.3.2 Assembly
4.3.2.1 Motors with a NEMA coupling (SM8, SM9)
• Apply a waterproof, acid-free grease to the inside part of the
coupling (e.g. Mobil FM 102, Texaco Cygnus 2661, Gleitmo
746). This grease minimises friction and provides additional
protection against penetration by sand.
• When joining the motor and pump, make sure that the tooth-
ing is enveloped by an O-ring. This O-ring prevents sand and
dirt from penetrating into the shaft toothing.
• Align the pump shaft with the motor shaft and move the pump
and motor together.
• The pump shaft and motor shaft must not be connected rig-
idly (coupled) in the axial direction.
• The coupling should be fastened on the pump shaft and
should slide on the motor shaft.
• Use only fastening screws of the appropriate grade and di-
mensions, which have been specified and approved by the
pump manufacturer.
• Observe the tightening torques specified by the pump man-
ufacturer.
• Screw the motor to the assembly and tighten the fastening
screws in diagonally opposite sequence according to the
specifications.
4.3.2.2 Motors with shaft coupling
(SM10, SM12, SM14)
The installation of motors and pumps requires special knowl-
edge of pump adjustment, and should be carried out according
to the requirements of the specific pump.
During installation, it must be ensured that the connecting ele-
ments are adequately dimensioned and that the rotor can move
freely.
4.3.3 Final checks
If the coupling point is freely accessible during operation, then
it must be protected against contact!
4.4

Connecting the motor cable

• Never let the cable come in contact with sharp edges.
