Also, it must be made sure that the floating switch can move freely.
The pump is equipped with a floating switch (2) causing the unit to cut in or out automatically as a
function of the water level as soon as the water level has reached, or dropped below, the cut-out level,
the pump will cut out. When the water level reaches or raises above the cut-in level, the pump will
resume operation. The cut-in and cut-out levels can be adjusted by shortening or lengthening the
freely movable cable (3) of the floating switch. The length of the cable can be set at the cable duct (4)
located at the carrying handle (5) of the pump. In this regard, the relevant part is the freely movable
part of the cable leading from the cable duct to the floating switch. If this length increases, the cut-out
level will decrease, and the cut-in level will augment. Vice versa, if its length decreases, the cut-in
level will increase whereas the cut-out level will be lowered.
If this length increases, the cut-out level will decrease, and the cut-in level will augment. Vice versa, if
its length decreases, the cut-in level will decrease whereas the cut-out level will be raised. Shall the
pump continue to suck beyond the automatic cut-out level, the flow switch has to be operated
manually, e.g. by holding it in upright position. Only in this operation mode, the minimum suction
height can be reached as listed in the tec. data box. In this condition the pump has to be under
constant supervision to avoid dry running.

How to position the pump
When positioning the pump, please make sure that the max. submersion depth indicated in the
technical data will not be exceeded. Likewise, please make sure that the minimum self-priming level is
not fallen short of. If everything is properly set, the water level may decrease down to the minimum
suction level once the pump is operating.
Please position the pump on solid ground. Avoid placing it on lose stones or sand. When positioning
the pump, please do make sure that the pump cannot tip over or sink into the ground with its intake
openings (6). The penetration of sand, mud or comparable matters is to be avoided.
To position, lift up or carry the pump, please use only the carrying handle. If required for lowering or
raising the pump, you may connect a suitable lowering rope to the carrying handle. In no case must
the pressure hose, the mains cable or the cable of the floating switch be used to position, to lift up or
to carry the pump.
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 splashwater-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.
