6.7 Fitting the submersible drop cable
It is recommended to join the submersible drop cable
and the motor cable by means of a Grundfos cable
termination kit, type KM.
For larger cross-sections, please contact Grundfos.
6.8 Pipework connection
If a tool, e.g. a chain pipe wrench, is used when the
riser pipe is fitted to the pump, the pump must only
be gripped by the pump discharge chamber.
When connecting plastic pipes, a compression
coupling should be used between the pump and the
first pipe section.
Where flanged pipes are used, the flanges should
be slotted to take the submersible drop cable.

6.8.1 Cable clips
Cable clips must be fitted every 3 metres.
See fig. 11.
When connecting plastic pipes, some slackness
must be left between each cable clip as plastic pipes
expand when loaded.
Where flanged pipes are used, the cable clips
should be fitted above and below each joint.

Note
For pumps fitted with plastic pipes, the
expansion of the pipes when loaded
should be taken into consideration, when
deciding on the installation depth of the
pump.
