8. Slide the guide claw between the guide rails and
lower the pump into the pit by means of a chain
secured to the lifting bracket of the pump. When
the pump reaches the auto-coupling base unit,
the pump will automatically connect tightly.
9. Hang up the end of the chain on a suitable hook
at the top of the pit and in such a way that 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 cables are not sharply bent or
pinched.
11. Connect the power cable and the monitoring
cable, if any.

Proceed as follows:
1. Fit the crossbar in the pit.
2. Fit the stationary part of the auto coupling on top
of the crossbar.
3. Fit the adapted piece of pipe for the movable part
of the hookup auto coupling to the pump outlet.
4. Fasten a shackle and a chain to the movable part
of the hookup auto coupling.
5. Clean out debris from the pit before lowering the
pump.
6. Lower the pump into the pit by means of the
chain secured to the lifting bracket. When the
movable part of the auto coupling reaches the
stationary part, the two will automatically connect
tightly.
7. Hang up the end of the chain on a suitable hook
at the top of the pit and in such a way that the
chain cannot come into contact with the pump
housing.
8. 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 cables are not sharply bent or
pinched.
9. Connect the power cable and the monitoring
cable, if any.
7.2 Free-standing submerged installation
Pumps for free-standing submerged installation can
stand freely on the bottom of the pit or similar
location. See fig.
on page
and fig.

.
In order to facilitate service on the pump, fit a flexible
union or coupling to the elbow on the outlet line for
easy separation.
If a hose is used
, make sure that the hose does not
buckle and that the inside diameter of the hose
matches that of the outlet port.
If a rigid pipe is used
, fit the union or coupling, non-
return valve and isolating valve in the order
mentioned, when viewed from the pump.
If the pump is installed in muddy conditions or on
uneven ground, we recommend that you support the
pump on bricks or a similar support.
Proceed as follows:
1. Fit a 90 ° elbow to the pump outlet and connect
the outlet pipe or hose.
2. Lower the pump into the liquid by means of a
chain secured to the lifting bracket of the pump.
We recommend that you place the pump on a
plane, solid foundation. Make sure that the pump
is hanging from the chain and not the cable.
3. Hang up the end of the chain on a suitable hook
at the top of the pit and in such a way that the
chain cannot come into contact with the pump
housing.
4. 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. Make sure that the
cables are not sharply bent or pinched.
5. Connect the power cable and the monitoring
cable, if any.
The free end of the cable must not be
submerged as water may penetrate
through the cable into the motor.
The free end of the cable must not be
submerged as water may penetrate
through the cable into the motor.
The free end of the cable must not be
submerged as water may penetrate
through the cable into the motor.
If several pumps are installed in the same
pit, the pumps must be installed at the
same level in order to allow optimum pump
alternation.
