Free-Standing Submerged Installation - Grundfos SEG AUTOADAPT Montage- Und Betriebsanleitung

8. Hang up the end of the chain on a suitable hook
at the top of the tank and in such a way that the
chain cannot come into contact with the pump
housing.
9. Adjust the length of the motor 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 tank.
Make sure that the cables are not sharply bent or
pinched.
10. Connect the motor cable and the monitoring
cable, if any.
Hookup auto-coupling system, see fig. B on
page 571.
Proceed as follows:
1. Fit the crossbar in the tank.
2. Fit the adapted piece of pipe for the movable part
of the hookup auto coupling to the pump
discharge port.
3. Fasten a shackle and a chain to the movable part
of the hookup auto coupling.
4. Clean out debris from the tank before lowering
the pump.
5. Lower the pump into the tank by means of the
chain secured to the pump lifting bracket.
6. Hang up the end of the chain on a suitable hook
at the top of the tank and in such a way that the
chain cannot come into contact with the pump
housing.
7. Adjust the length of the motor cable by coiling it

8.2 Free-standing submerged installation

Pumps for free-standing submerged installation can
stand freely on the bottom of the tank or similar
location. See fig. C on page 572.
The pump must be mounted on separate feet
(accessory).
In order to facilitate service on the pump, fit a flexible
union or coupling to the discharge 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 discharge port.
If a rigid pipe is used, the union or coupling, non-
return valve and isolating valve should be fitted in
the order mentioned, when viewed from the pump.
If the pump is installed in muddy conditions or on
uneven ground, it is recommended to support the
pump on bricks or a similar support.
Proceed as follows:
1. Fit a 90 ° elbow to the pump discharge port,
and connect the discharge pipe or hose.
2. Lower the pump into the liquid by means of a
chain secured to the lifting bracket of the pump.
It is recommended to 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 tank and in such a way that the
chain cannot come into contact with the pump
housing.
4. Adjust the length of the motor 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 motor cable and the monitoring
cable, if any.
If several pumps are installed in the
same tank, the pumps must be installed
Note
at the same level in order to allow
optimum pump alternation.
