INSTALLATION
The motor must not sit on the bottom of the well as this can lead to tensions and slag-
ging of the motor. This would mean that heat dissipation is no longer guaranteed and
the motor could overheat.
In addition, the pump should not be installed at the same height as the filter pipe.
The intake current can draw up sand and solid material, which would mean that the
motor cooling is no longer guaranteed. This would also result in increased wear of the
hydraulics. To prevent this, it may be necessary to use a cooling shroud or install the
pump in the vicinity of unperforated well casings.

1 Unit
2 Ascending pipe
3 Supporting clamp
4 Lifting equipment
5 Connection cable
6 Minimum submersion
NOTICE:
Observe the following prior to installing threaded pipes:
• The threaded pipes must be screwed into each other leak-tight and firmly.
• When screwing in the pipes, make sure that the pipes are aligned (not tilted)
• Observe the submersible pump's direction of rotation and use suitable
• Threaded pipes must be secured against inadvertently coming loose.
1. 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.
2. 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.
