Lowering of the RCP along the guide tube
The safety hints
in the previous sections must be observed!
The RCP together with the guide piece is connected onto the guide tube and lowered along it until it
automatically sits in it‘s final position (see Figure 23). When doing this, carefully feed the power cable
downwards at the same time.
To ensure the RCP will tilt enough to lower correctly on the guide tube, the angle of the pump created by the
lifting hook when suspended by the hoist has to be checked prior to lowering. For this purpose, begin lifting the
pump from a horizontal surface and check that the rear end of the fixing support rises 2- to 4- cm from the floor
before the front end begins to lift clear (see Figure 22).

ATTENTION
The power cable should be connected to the wire rope or chain in such a manner
that it cannot become entangled in the propeller and that it is not subjected to any
tension.
After lowering of the RCP the tension of the wire rope or the chain should be released.
