Grease the gasket of the guide claw
before lowering the pump into the tank.
When the pump has reached the base

stand, shake the pump by means of 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 tank and in such a way that the
chain cannot come into contact with the pump
housing.
10. 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.
11. Connect the motor cable and the monitoring
cable, if any.
The free end of the cable must not be

1. Fit a crossbar in the tank.
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
discharge port.
4. Fasten a shackle and a chain to the movable part
of the hookup auto coupling.
5. Clean out debris from the tank before lowering
the pump.
6. Lower the pump into the tank 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.

7.2 Free-standing submerged installation

Pumps for free-standing submerged installation can
stand freely on the bottom of the tank or the like.
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 pipe for easy
separation.
If a hose is used, make sure that the hose does not
buckle and that the inside diameter 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.
1. Fit a 90 ° elbow to the pump discharge port and
connect the discharge pipe/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.
