9 4 3 Pipes with thread
If you use pipes with a thread instead of a flange the instal-
lation is basically the same.
The threads have to be sealed with hemp- or teflon tape.
Make sure that the threads cannot work loose over time.

9 4 4 Removal
If you have to remove the pump system it is the same
principle as the installation in the other direction. When
removing the pump the pipes will be full of water and will
be heavier.
Note: When you lift the pump system
out of the well the pipes are full of
water This causes additional weight
In the table below you can see the additional weight of the
water per meter pipe length.

9 4 5 Cable splicing
To connect the motor cable with a cable extension you
should connect the cable ends with a splicing kit.
It is very important that the cable joints are fully sealed
otherwise moisture could cause a short circuit and this will
damage the pump system.
For more information about connecting cable ends with a
splicing kit see the "submersible cable splicing" manual in
the package of the splicing kit.
