The pump must only be lowered into, and raised out of, the liquid using a suitable lowering rope. Please use a
rope made of stainless steel or synthetic materials such as nylon. Considering the risk of breaking involved, ropes
which tend to the formation of rust, weathering, mouldering etc. must not be used.
Please keep in mind that the rope does not only have to bear the weight of the pump plus that of the water-filled
pressure line and the connection cable, it also has to resist to the strain occurring in operation. Therefore, you
should always use a rope which is capable of carrying five times the weight of the pump plus filled pressure line.
The standard equipment of the most models includes a high-grade lowering rope (10).
To fasten the rope to the pump, please use the carrying handle (11) of the device. Make sure that the pump will
move into a vertical position when lifted up with the rope.
The lowering rope, the connection cable and the pressure line have to be tied together at intervals of about 2 m
using a suitable adhesive tape or cable ties to keep them from getting entangled while the pump is raised or
lowered. Carefully lower the pump with the lowering rope down into the well, shaft etc. Make sure that the device
will not bump or rub against the circumference of the cavity. During lowering, the pump has to be adjusted upright
since it must only be operated in a vertical position.
The pump must be fully immersed in the liquid. The inlet of the intake line should be at least 0.5 m below the
surface of the water. This will prevent air from being taken in. The minimum distance between the inlet of the
intake line and the bottom should be 0.5 m to prevent sludge, sand, stones etc. from being sucked in.
Moreover, when positioning the pump care should be taken that it will not touch this circumference of the well,
shaft etc. during operation. Therefore, it is recommended to apply a suitable device at the opening of the well
shaft where the lowering rope can be fastened after the proper positioning of the pump. When selecting this
device, please do make sure that it will hold the weight of the pump plus that of the filled pressure line and the
connection cable on the one side, and the load occurring during operation on the other.
6. Electrical connection
The unit is equipped with a mains connection cable and a mains plug. It must only be replaced by qualified staff to
avoid any danger. Please do not use the mains connection cable to carry the pump, and do not use this cable to
pull off the plug from the socket, either. Protect the mains connection cable and mains plug from heat, oil or sharp
edges.
The values stated in the technical details have to correspond to the mains voltage. The person
responsible for the installation has to make sure that the electrical connection is earthed in
compliance with the applicable standards.
The electrical connection has to be equipped with a highly sensitive residual current circuit-
breaker (FI switch): ∆ = 30 mA (DIN VDE 0100
-739).
If extension cables are used, their cross-section must not be smaller than that of rubber-
sheathed cables of the H07RN-F (3 x 1.0 mm²) short code. The mains socket and the plug-
and-socket elements have to be in splash water-proof design.
7. Putting into operation
Nobody must be in the water while the pump is running.
The pump must only be operated in the performance range indicated on the type plate.
Dry-running - i.e. operating the pump without discharging water - is to be avoided since the
absence of water may cause the pump to run hot. This may cause considerable damage on
the device.
Please make sure that the electrical plug connections are in the flood-proof area.
As long as the device is connected to the electrical mains, one must never reach with one’s
hands into the opening of the pump.
The pump must not run while the pressure port or the pressure line are closed.
