4.1 Installation
4.1.1 Installation in wells
The pump may not be placed or installed on the ground of the
well. In order to avoid this, the pump should be fastened to a steel
cable during installation.
The pump may not, under any circumstances, be lifted on the
electrical connection cable and pressure line.
The pump must remain completely under water in order to ensure
sufficient cooling.

4.1.2 Water quantity
The water quantity in the well must be greater than that required
by the pump. This will prevent the pump running dry or starting up
too frequently and then turning off again.
4.1.3 Avoiding damage to cables
In order to avoid damage to the motor’s power cable whilst being
lowered into the well this should be fastened to the pressure line
using cable clamps. Fastening them together at two meter
intervals is recommended.
