Installation instructions
▪ For horizontal installation, a device guiding the flow along the motor (cooling
jacket, shroud, etc.) is required.
▪ For horizontal installation, install the pump set with the venting pointing
upwards at an angle.
▪ Lay the pipe in such a way that no piping forces (weights, torsional forces,
vibrations, etc.) can act on the pump set. To compensate such forces, we
recommend fitting a tailored expansion joint between the pump set and the
pipe.
Positioning the pump set
✓ The tank or well have been prepared in accordance with the instructions.
✓ The concrete floor is of sufficient strength.
✓ An extension cable of the specified length has been connected to the power
cable.
1. Arrange the pedestals in accordance with the general arrangement drawing
and fasten them to the foundation with the foundation bolts, anchor bolts, etc.
provided by the operator.
2. Position and fasten the pump set (including cooling jacket) on the pedestals.
3. Fit the expansion joint, if any.
4. Install the piping in accordance with the piping layout. Observe the installation
instructions of the pipe supplier.
5. Fasten the electric cable as well as any measuring and control cables to the pipe
with suitable fasteners (e.g. cable clips). Attach them every three metres.

5.4 Notes on electrical connection

KSB's submersible borehole pumps < 1000 V are wired for DOL starting. During start-
up and run-up the voltage must not fall below the value specified in the order
documentation.
If this starting method is not permitted by the power supply utility, starting devices
to reduce starting currents must be provided (e.g. star-delta contactors,
autotransformers, starting resistors or soft starters ).
