How to set the floating switch
Please make sure that the pump will cut out as soon as the water level
decreases and the floating switch has reached the cut-out level.
Also, it must be made sure that the floating switch can move freely.
In manual operation mode the pump has to be under constant supervision to
avoid dry running.
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.
Shall the pump continue to suck beyond the automatic cut-out-level the float switch hast to
be operated manually, e.g. by holding it in upright position. To do this, you must remove the
cable of the floating switch from the cable guide (4). Then adjust the floating switch to the
intended holder (13) by sliding the switch vertically into the holder from above so that the
cable pointes downside. Just in this operation mode the min. suction level given in the
technical data chart can be achieved. However, the pump must be constantly monitored 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.

Setting the clear or dirty water operation by adjusting the pump foot
During the entire installation (settings), the device must not be connected to
the mains
The pump has an adjustable pump foot for use in clear or dirty water operation. The pump
foot is factory-set for use as a clear water pump and is in this operating condition for a max.
grain size of 1 mm suitable. In this setting, the minimum suction level in manual mode is 1
mm (wicks dry).
With the dirty water setting with the pump foot extended, the pump is suitable for a particle
size of max. 30 mm provided. The minimum suction level is then 40 mm.
The setting of the different operating modes is carried out as follows:
1. Remove the pump from the water after disconnecting the power.
2. Turn the pump upside down so that the pump foot is visible.
