oughly and ensure you have understood them. Keep this operating manual for future reference.
Please note efore starting:
The pump can be attached to any protective contact socket, which has been installed properly. The
socket needs a supply voltage of 230>V and a fuse of at least 6> .
Warning! If the pump is meant to be used near swimming pools or garden ponds and in their protect-
ive area, it needs to be equipped with an earth fault circuit breaker with a normal tripping current of
max. 30>m . The pump must not be operate if there are people within the pool or pond. Please contact
an electrician.
Safety notes for the pump
Know the application of the pump and ensure you are familiar with the limitations and potential
dangers.
Make sure that the electricity source corresponds to the requirements of the device.
Disconnect the pump from the electricity supply before carrying out any maintenance work.
Release the pressure from the system before maintaining a part.
Release the liquid from the system before maintaining the pump.
Secure the pressure line before starting the pump. n unsecured pressure line can retaliate
and thus lead to injuries and/ or damages.
Check the hose for wear and damage before every use. Ensure that all connections are se-
cured.
Occasionally check the pump and the system components. Keep the pump and the system
free of residues and foreign bodies. If necessary, carry out a routine maintenance.
Keep a remedy for pressure relief near pumps, which pressure lines can be closed off or
clogged.
Personal safety
lways wear protective glasses when working with the pump.
Keep your working area clean, tidy and well illuminated. Store tools and equipment when the
pump is not in use.
Keep bystanders away from your working area.
Make sure to make the working area safe for children by using padlocks and main switches
and by removing ignition keys.
When connecting an electrically powered pump, all electrical and safety instructions need to
be regarded.
The pump motor is equipped with an automatic resetting thermal protection and can start un-
expectedly again.
Danger of electric shock: This device is designed to be only operated with 230>V. To reduce
the risk of electric shock, ensure that the pump is connected to a properly installed safety plug.
The entire wiring should be done by a qualified technician.
Protect the power cable from sharp objects, hot surfaces, oil, and chemicals. void bending
the cable. Damaged or worn cables need to be replaced immediately.
Use cables with a sufficient size to minimise a voltage drop to the motor.

Additional Safety Precautions
Please have the following things checked y an expert, efore using the pump (important for
your own safety, too):
Ground connection
Neutral conductor
Fault-current circuit breaker needs to comply with the safety regulations of the power plants
and needs to work faultless.
The electrical connections need to be protected from humidity.
When a danger of flooding occurs, the electrical connections need to be placed in a high area.
The circulation of aggressive liquids as well as the circulation of abrasive substances is to be
avoided.
The motorised waste water pump needs to be protected from frost.
The pump needs to be protected from dry-running. The pump should be kept away from chil -
dren.
Resistance
•The waste water pump is suited for a circulation of water with a maximal temperature of 35>℃.
•The pump possibly is not suited for other liquids, especially motor oils, cleaning detergents
and other chemical products.
Assem ly
The waste water pump is installed the following way:
•in stationary position with a fixed pipeline or
•in stationary position with a flexible pipe.
Please note!
The pump should never be installed hanging self-supporting of the pressure line or the electricity
cable. The waste water pump needs to be hung up by the designated handle or placed on the floor of
the shaft. To ensure the impeccable functioning of the pump, the shaft floor needs to be kept free of
mud and dirt of any kind.
When the water level has sunk too low, the mud in the shaft dries fast and stops the pump from start -
ing. It is necessary to regularly check the pump (by performing tests before operation). The float is ad-
justed to allow the pump to start immediately.
Note!
The pump should have a minimum size of 40 × 40 × 50>cm, so that the floater can move freely.
Power supply
The pump is equipped with a proper protective contact plug. The pump is meant to be connected to a
220/230>V~50>Hz safety socket. Ensure that the socket is sufficiently secured (at least 6 > ) and is in
an excellent condition. Place the electricity plug into the socket and the pump is ready for use.
Important Note!
If the main cable or the socket has been damaged due to external influences, repairs on the cable are
prohibited. Repair-work may only be carried out by a qualified technician.

Areas of application
This pump is mainly used as a cellar pump. When placing this it into a shaft, the pump provides pro-
tection from flooding. dditionally the pump can be used anywhere, where water needs to be transpor-
ted from one area to another, e.>g. at home, in agriculture, in gardening,for sanitary work and so forth.
Work settings
fter having read the operating manual thoroughly and understanding it, the pump can be put into op-
eration. Please note the following things in advance:
The pump is on the floor of the shaft.
Ensure that the pressure line is attached properly.
Check, whether the electrical connection of 230>V and 50>Hz is given. ll fibre particles, which
might have collected in the pump casing, should be removed with a water stream.
Check whether the socket is in a good condition.
Make sure that water and humidity never reach the main components.
void the pump from running dry.
Maintenance instructions
•This waste water pump is an approved, maintenance-free, high-quality product, which has
been subject to a strict final inspection.
•We recommend a regular inspection and maintenance, to ensure a longer lifespan of the
device and a interruption-free operation.
Important Notes!
•Before every maintenance work, pull the electricity plug.
•In case the pump should be transported frequently, it needs to be cleaned with clear water
after every use.
•When installing the pump stationary, the function of the floater should be checked every
3>months.
•ll fibre particles, which have been collecting in the pump casing, should be removed with a
water stream.
•Every 3>months, the serrated blade should be freed from mud.
•Remove the residues on the float with clear water.
Cleaning the drive wheel
If there is excessive residues collecting in the pump casing, the bottom part of the pump needs to be
demounted the following:
1. Loosen the 4 screws on the bottom of the inlet cage.
2. Remove the suction cage from the pump’s casing.
3. Clean the drive wheel with clear water. Important! The pump must not e placed on the

Adjusting the on/off of the operating point
The on/off switching point and the shut-off point of the floating switch can be adjusted via the floating
switch and its snap holder. Before putting the pump into operation, check the following points:
1. The float switch needs to be installed in a way that the filling level of the shut-off point and the
filling level of the switch-on point are activated easily, with little effort.
To check this, place the pump into a container filled with water. Lift the float carefully by hand
and sink it again. Then check if the pump switches on and off.
2. Ensure, that the distance between the float switch head and the snap holder is not too small.
proper operation cannot be guaranteed, if the gap is too small.
3. When adjusting the float switch, ensure that it does not touch the basis, before switching the
pump off. Attention! Danger of dry-running.
To alter the pump and allow a lower suction
point, please first of all remove the two screws
of the back float cover.
The cover can then be pushed away downward.
We recommend tilting the pump sideways, to re-
move the cover easier.

There are two different mounting possibilities of
both floats. Picture one shows the factory setting
of the float and bracket mounting. Here the up-
per float can only move.
With this way of mounting the switch-on point is
at 120>mm/140>mm water level depending on
the pump variation. See the following table:

51537
12051538
51539
51540 140
51541
To reassemble the pump to version 2, both
screws need to be loosened and the brackets to
be turned. This allows both floats to move and
the switch-on point to sink.
Tighten the screws up again carefully.
With this assembly, the switch-on point is at 40
mm water level/ 60 mm depending on the pump
variation. See the following table.
