5.4. HOW TO SET 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.
The pump is equipped with a floating switch (3)
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 (4) of the floating switch. The length
of the cable can be set at the cable duct (5) located
at the carrying handle (6) of the pump.
To prevent the float from stopping, it is necessary
to switch to manual mode by locking the float in a
vertical position.
In this case, you should stay close to the pump to
avoid dry running.

5.5. 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 circuitbreaker (FI
switch) : Δ = 30 mA.
• If extension cables are used, their cross-section
must not be smaller than that of rubbersheathed
cables of the H07RN-F (3 x 1,0 mm²) short code.
The mains socket and the plugand-socket ele-
ments 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 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.
Please inspect the pump visually prior to each use.
This applies in particular to the mains connection
line and the mains plug. Make sure that all screws
are firmly tightened, and verify the perfect condition
of all connections. A damaged pump must not be
used. In any case of damage, the pump has to be
inspected by qualified service staff. Each time the
pump is put into operation, please make sure that
the pump is set up securely and firmly standing.
To put the unit into operation, please plug the mains
plugs into a socket. If the water level has reached
or exceeded the cut-in level, the pump will start
to run immediately. To stop the operation of the
