INSTALLATION

Note:
Elastomer parts and coatings become brittle over time. If the product is to be stored
for longer than 6 months, we recommend checking these parts and replacing them as
necessary. Consult the manufacturer in this regard.
• If the storage period exceeds one year, we recommend removing rotating parts and
checking their correct condition and function. Also connect the pump to the power
supply without starting up the motor. For this purpose, the water level sensor must
have been removed completely from the fluid to prevent a motor start. Connect the
unit to the power supply to charge the electrolyte capacitors of the installed frequency
converter.
CAUTION: beware of moisture!
Moisture penetrating the cable will damage both
the pump and the cable. For this reason, never im-
merse the cable end in the fluid or any other liquid.

Return delivery

Pumps that are returned to the factory must be properly packaged. This means that
impurities have been removed from the pump and that it has been decontaminated if
used with fluids that are hazardous to health.
For shipping, the parts must be packed in tear-proof plastic bags of sufficient size in
such a manner that they are tightly sealed and leak proof. Furthermore, the packaging
must protect the pump from damage during transportation. If you have any questions,
please contact the manufacturer!
6. Installation
Observe the following to prevent damage to the product or serious injury during
installation:
• Installation work – assembly and installation of the submersible pump – may only be
carried out by qualified persons. The safety instructions must be followed at all times.
• The submersible pump must be inspected for transport damage before any installation
work is carried out.
6.1.

General

In the event of pumping through longer pressure pipes (particularly in the case of longer
ascending pipes), pressure surges can occur.
Pressure surges can result in destruction of the pump/system and noise pollution due
to valves opening and closing suddenly. Water hammers can be reduced or prevented
by applying suitable measures (e.g. non-return valves with an adjustable closing time,
electrically actuated shut-off devices, special routing of the pressure pipe).
