INSTALLATION English
NOTICE:
Observe the following prior to installing threaded pipes:
• The threaded pipes must be screwed into each other leak-tight and
firmly. To achieve this, wrap the threaded pin with hemp or Teflon tape.
• When screwing in the pipes, make sure that the pipes are aligned (not
tilted) to ensure that the thread is not damaged.
• Observe the submersible pump’s direction of rotation and use suitable
threaded pipes (right-hand or left-hand thread) so that they do not
come loose by themselves.
• Threaded pipes must be secured against inadvertently coming loose.
13. Extend the connection cable installed ex works according to the space available in the
borehole. For this purpose, use the enclosed sealing kit to extend by the required length.
14. Fit the first pipe to the pressure connection of the of the pump. Screw together all
necessary pipes if only few pipes are required and the lifting equipment has reached
a sufficient height.
15. Fit a mounting bracket to the pressure connection of the respective last pipe and fit
a supporting clamp below the flange.
Make sure that the cable is not damaged by the supporting clamp. The cable must
always be routed outside the supporting clamp!
16. Secure the lifting equipment to the mounting bracket and lift the complete unit.
17. Swivel the unit over the borehole and slowly lower it.
Make sure the cable and well walls are not damaged!
18. Route the connection cable along the piping. Always fasten the cable below and above
a pipe adaptor using a cable clip.
19. Place two square timbers over the well shaft. Lower the unit until the supporting clamp
is resting on the square timbers.
20. If necessary, connect an additional pipe and repeat the process until the pump has been
positioned at the required depth.
21. Disassemble the mounting bracket from the pressure pipe and fit the well closure
(e.g. well cover) on the discharge pipe.
WARNING: danger of crushing!
During installation the entire weight is resting on
the lifting equipment and the bearer cable may
be subject to tension. This can result in severe
crushing! Before disassembling the mounting bra-
cket, make sure that the bearer cable is NOT under
tension.
22. Fasten the lifting equipment to the well closure and hoist the entire unit (consisting of
the pump, piping and well closure).
