3.2 Mechanical installation

DANGER
Electric shock
Death or serious personal injury
Switch off the power supply before
starting any work on the product.
Make sure that the power supply can-
not be accidentally switched on.
CAUTION
Sharp element
Minor or moderate personal injury
Wear personal protective equipment.
Make sure that persons cannot come
into contact with the pump impeller.
Do not install the pump hanging from the
electric cable or the outlet pipe.
3.2.1 Foundation
Place the pump on a plate or on bricks so that the
inlet strainer is free of sludge, mud or similar
materials. See fig. Place the pump on a plate.

Place the pump on a plate
3.2.2 Lifting the pump
Do not pull or lift the product by the power
cable.
Lift the pump using the pump handle. Do not lift the
pump by the power cable or by the outlet pipe or
hose.
If the pump is installed in a well or tank, lower and lift
it by means of a wire or chain fastened to the pump
handle.
3.2.3 Positioning the pump
The pump can be used in vertical or horizontal
position. See fig. Position of the pump.
During continuous operation, the motor and the pump
inlet must always be completely covered by the
pumped liquid.
During intermittent operation, the motor must always
be half submerged into the pumped liquid.

Position of the pump
When the pipe or hose has been connected, place
the pump in its operating position.
Position the pump so that the pump inlet will not be
blocked or partly blocked by sludge, mud or similar
materials.
In the case of permanent installation, the pit must be
cleared of sludge, pebbles, etc. before the pump is
installed.
3.2.4 Pipe connection
For permanent installation, we recommend that you fit
a union, a non-return valve and an isolating valve in
the outlet pipe.
3.2.5 Installation on auto coupling
See figs A and B in the Appendix.
Pumps for permanent installation can be installed on
a stationary auto coupling and operated completely or
partially submerged in the pumped liquid.
1. Drill mounting holes for guide rail bracket on the
inside of the pit and fasten the guide rail bracket
provisionally with two screws.
2. Place the auto coupling base unit on the bottom of
the pit. Use a plumb line to establish the correct
positioning. Fasten with heavy-duty expansion
bolts. If the bottom of the pit is uneven, the auto-
coupling base unit must be supported so that it is
level when being fastened.
3. Assemble the outlet line in accordance with the
generally accepted procedures and without
exposing the line to distortion or tension.
4. Knock the guide rails on to the spigots of the
bottom part of the auto coupling. Bevel the inside
of the guide rails to facilitate installation. The
guide rails must fit tightly on the spigots. We
recommend 3/4" medium size pipes as guide
rails.
5. Adapt the length of the guide rails to fit precisely
the bracket at the top.
