3. 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!
4. Secure the lifting equipment to the mounting bracket and lift the complete unit.
5. Swivel the unit over the borehole and slowly lower it.
Make sure the cable and well walls are not damaged!
6. Route the connection cable along the piping. Always fasten the cable below and above
a pipe adaptor using a cable clip.
7. Place two square timbers over the well shaft. Lower the unit until the supporting clamp
is resting on the square timbers.
8. If necessary, connect an additional pipe and repeat the process until the pump has been
positioned at the required depth.
9. 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 crush-
ing! Before disassembling the mounting bracket,
make sure that the bearer cable is NOT under
tension.
10. Fasten the lifting equipment to the well closure and hoist the entire unit (consisting
of the pump, piping and well closure).
11. Remove the supporting clamp, square timbers and guide the connection cables to the
outside through the well closure.
12. Place the unit on the well and fasten the well closure.
13. Fit the pressure pipe to the tap on the well closure and route the connection cables to
the switchbox.
