‐ Do not touch the sharp edges of the
impeller, grinder head, and grinder ring
without wearing protective gloves.
CAUTION
Biological hazard
Minor or moderate personal injury
‐ Make sure to seal the pump outlet
properly when fitting the outlet pipe,
otherwise, water may spray out.

4.2 Installation types
SEG pumps are designed for two installation types:
• submerged installation on auto coupling
• free-standing submerged installation
4.2.1 Installation on auto coupling
Pumps for permanent installation can be mounted
on a stationary auto-coupling guide-rail system or a
hookup auto-coupling system.
Both auto-coupling systems facilitate maintenance
and service as the pump can easily be lifted out of
the pit.
Before installation, make sure that the
atmosphere in the pit is not potentially
explosive.
Use loose flanges to ease the installation and to
avoid pipe tension at the flanges and bolts.
Make sure that the pipes are installed
without undue force. No loads from the
weight of the pipes must be carried by the
pump.
Do not use elastic elements or bellows in
the pipes. Never use these elements to
align the pipes.
Auto-coupling guide-rail system
Proceed as follows:
1. Drill mounting holes for the guide-rail bracket on
the inside of the pit, and fasten the guide-rail
bracket provisionally with two anchor bolts.
2. Place the auto-coupling base unit on the bottom
of the pit. Use a plumb line to establish the
correct positioning. Fasten the auto coupling with
heavy-duty anchor bolts. If the bottom of the pit
is uneven, the auto-coupling base unit must be
supported.
3. Connect the outlet pipe in accordance with the
generally accepted procedures. Avoid exposing
the pipe to distortion or tension.
4. Place the guide rails in the auto-coupling base
unit, then adjust the length of the rails accurately
to the guide-rail bracket at the top of the pit.
5. Unscrew the guide-rail bracket, fit it on the top of
the guide rails and finally fasten it firmly to the pit
wall.
The guide rails must not have any axial
play as this may cause noise during
pump operation.
6. Clean out debris from the pit before lowering the
pump.
7. Fit the guide claw to the pump outlet. Grease the
gasket of the guide claw before lowering the pump
into the pit.
8. Slide the guide claw between the guide rails and
lower the pump into the pit by a chain secured
to the lifting bracket. When the pump reaches the
auto-coupling base unit, the pump automatically
connects. Shake the pump by the chain to make
sure that it is placed in the correct position.
9. Hang up the end of the chain on a suitable hook
at the top of the pit so the chain cannot come into
contact with the pump housing.
10. Adjust the length of the power cable by coiling it
up on a relief fitting to ensure that the cable is not
damaged during operation. Fasten the relief fitting
to a suitable hook at the top of the pit. Make sure
that the cable is not sharply bent or pinched.
11. Connect the power cable and the control cable, if
any.
The free end of the cable must not be
submerged as water may penetrate
through the cable into the motor.

Hookup auto-coupling system
Proceed as follows:
1. Fit a crossbar in the pit.
2. Fit the stationary part of the auto coupling on the
top of the crossbar.
