4. Mechanical installation

The compact design makes the pumps suitable for
both temporary and permanent installation. The
pumps can be installed on an auto-coupling system
or on a ring stand to the bottom of the pit.

4.1 Installation requirements

Pump installation in pits must be carried
out by specially trained persons.

It must be possible to lock the main
switch in position 0. Type and

Death or serious personal injury
‐
Make sure there is at least 3 m free
cable above the maximum liquid level.
Maintenance and service work must be
carried out when the pump is outside the
pit. For safety reasons, all work inside pits
must be supervised by a person outside
the pit.
WARNING
Crushing hazard
Death or serious personal injury
‐
Make sure the lifting bracket is
tightened before lifting the pump.

4.2 Installation on auto-coupling

Pumps for permanent, vertical installation in a pit can
be installed on a stationary auto-coupling unit.
Make sure that the pipes are installed
without the use of undue force. No loads
from the weight of the pipes must be
carried by the pump. Use loose flanges to
ease the installation and to avoid pipe
tension at the flanges.
Do not use elastic elements or bellows to
connect the pipes.
In some installations, a plinth is required
beneath the auto coupling to ensure the
correct installation of the pump.
The free end of the cable must not be
submerged as water may penetrate into
the motor.
The guide rails must not have any axial play as this
can cause noise during operation.
Proceed as follows:
1. Drill mounting holes for the guide-rail bracket on
the inside of the pit and fasten the guide-rail
bracket with two screws.
