Start-up
Connecting the pipe or hose line
The device may be operated using either a hose line or a pipe.
Ex factory, the device is delivered with a 1½" internal thread.
Please observe the following information regarding the water
discharge:
• Please note that making use of the reducer(7) might
decrease the device performance. The reducer(7) should
be shortened to the used diameter so as not to decrease
the device performance unnecessarily.
• Please note that the device cannot be moved as flexibly
when using a solid pipe.
• Please note that the maximum particle size is to be
reduced in proportion to the hose or pipe diameter.
• Please note that the conveying capacity declines with an
increasing length of the water discharge line.

3. When using a hose without thread:
Slide an appropriate hose clamp onto the hose.
4. Push the hose (inner diameter 25mm or 32mm) onto the
reducer(7) all the way to the stop.
5. Affix the hose by means of the hose clamp.
6. When using a hose with internal thread (1''):
Screw the hose connection onto the reducer(7).
7. Alternatively, you can also screw a hose with internal
threading (1½") directly onto the elbow(8).
Pipe
1. If possible, screw the pipe directly into the connection with
1½"internal thread(6) or use a suitable adapter.

Adjusting the float switch
The device comes equipped with a float switch(4) which
switches the device on or off automatically according to the
water level. Check the float switch(4) for proper functioning at
regular intervals.
Switching point Water level
TWP4025E
Height for switch-on Approx. 450mm
Height for switch-off Approx. 210mm

Height for switch-on Approx. 500mm
Height for switch-off Approx. 250mm
TWP11025E
Height for switch-on Approx. 600mm
Height for switch-off Approx. 180mm
The pumping height can be regulated by means of the float
switch(4) and its position in the float switch locking device(3).
Please observe the following information regarding the float
switch(4):
• Make sure that the float switch(4) always has enough
clearance and is not permanently activated. This could
prevent the automatic switch-off causing the device to run
dry. This would damage the pump.
• Make sure that the float switch(4) is able to move freely
and does not suffer from a limited mobility caused by
obstacles.
• Observe a sufficient distance between float switch(4) and
float switch locking device(3), for this could prevent the
automatic switch-off causing the device to run dry.
• Make sure that the position of float switch(4) is adjusted in
a way, that it does not lie flat on the ground. This could
prevent the automatic switch-off causing the device to run
dry.
1. If required, lock the float switch(4) in the desired position
by pushing the cable into the float switch locking device(3)
at the side of the pump.

Positioning the device
Please observe the following information regarding the device
set-up and before switching the device on:
• The float switch(4) must be able to move freely. The shaft
into which the device is lowered must not restrict the
mobility of the float switch(4) in any way.
• Do not leave the device running unattended.
• Make sure that the device is firmly placed on the ground or
safely suspended.
• When using the device in bodies of water with natural,
muddy ground, set the device up at a slightly elevation
position, e.g. on bricks.
• Check whether the hose or pipe was attached properly.
• Make sure that the power cable(2) is not under tensile
load and has enough clearance.
• Make sure that the mains connection corresponds to the
specifications provided in the technical data.
• Check the mains socket for its proper condition and
sufficient fusing.
• Make it impossible for moisture to reach mains plug or
socket. There is a risk of electric shock!
Warning of electrical voltage
Electric shock from damaged power supply cable.
Make sure not to hold or suspend the device by the
power supply cable under any circumstances.

Note
At the bottom of ponds and other waterbodies deposits
may have accumulated over time. To prevent the
device from being damaged, do not lower it all the way
to the ground unless you are certain that the water is
clean, in other words that the size of the dirt particles
in the water does not exceed 25mm.
1. Fasten the supplied nylon cord to the transport handle(1)
at the top of the device.

2. Lower the device into the water at a slight angle to allow
any remaining air to escape.
3. If you want the device to be positioned on the ground,
ensure that the latter is even.
4. Attach the nylon cord to an easily accessible position, so
you can pull the device back out after pumping has been
completed.
Operation
Switching the device on
Once you have completely installed the device as described in
the Start-up chapter, you can switch it on.
Warning of electrical voltage
Do not touch the mains plug with wet or damp hands.
1. Plug the mains plug into a sufficiently fused mains socket.
ðThe device will be switched on when the float switch(4)
is situated above the set or the maximum switch-on
height.
