Introduction
Thank you very much for purchasing this quality product. To minimise the risk of injury, we ask you to
comply with basic safety precautions, when using this product. Please read this operating manual thor-
oughly and ensure you have understood them. Keep this operating manual for future reference.
Please note before 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 A.
Warning! If the pump is meant to be used near swimming pools or garden ponds and in their
protective area, it needs to be equipped with an earth fault circuit breaker with a normal tripping current
of max. 30 mA. The pump must not be operated if there are people within the pool or pond. Please
contact an electrician.
Safety notes for the pump
General safety notes
•Know the application of the pump and ensure to be 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. An 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, the pressure lines of which can be closed off or
clogged.
Personal safety
•Always 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 unexpect-
edly re-start.
•Danger of electric shock: This device is designed to only be operated with 230 V. To reduce the
risk of electric shock, ensure that the pump is connected to a safety plug properly installed.
•The entire wiring should be done by a qualified technician.
•Protect the power cable from sharp objects, hot surfaces, oil, and chemicals. Avoid 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.
•Do not touch a running motor. Modern motors can reach very high temperatures when running.

Additional safety precautions
Have the following checked by an expert before using the pump (important for your own safety,
too):
•Ground connection
•Neutral conductor
•Fault-current circuit breaker needs to comply with the safety regulations 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 might not be suited for other liquids, especially motor oils, cleaning detergents, and
other chemical products.
Assembly
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
starting. It is necessary to regularly check the pump (by performing tests before operation).
•The float switch is adjusted to allow the pump to start immediately.
Note! The pump shaft 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 A) 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 into a shaft, the pump provides protection
from flooding. Additionally, the pump can be used, where water needs to be transported from one area
to another, e.g., at home, in agriculture, in gardening, for sanitary work and so forth.
Work settings
After thoroughly reading the operating manual and understanding it, the pump can be put into operation.
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 if the electrical connection has 230 V and 50 Hz. All fibre particles possibly collected in
the pump casing should be removed with a water stream.
•Check if the socket is in a good condition.
•Make sure that water and humidity never reach the main components.
•Avoid any running dry of the pump.
Maintenance instructions
•This waste water pump is an approved, maintenance-free, high-quality product subject to a strict
final inspection.
•We recommend a regular inspection and maintenance to ensure a longer lifespan of the device
and an interruption-free operation.
Important notes!
•Before every maintenance work, pull out the 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
3months.
•All fibre particles possibly collected in the pump casing should be removed with a water stream.
•Every 3 months, the shaft bottom should be freed from mud.
•Remove the residues on the float switch with clear water.
Cleaning the drive wheel
If there are excessive residues collected 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 casing.
3. Clean the drive wheel with clear water.
Important! The pump must not be placed on the drive wheel.
4. Build the pump back together in the reversed order.

Adjusting the on/off position 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:
1. The float switch needs to be installed so that the filling level of the shut-off point and the filling
level of the switch-on point can be activated with little effort.
To check this, place the pump into a container filled with water. Carefully lift the float switch by
hand and lower 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. A
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 modify the pump and allow a lower suction point,
first remove the two screws of the back float switch
cover.
The cover can then be pushed away downward. We
recommend tilting the pump sideways to more easily
remove the cover.

There are two different mounting possibilities of both
float switches. Fig. 1 shows the factory setting of the
float switch and bracket mounting. Here the upper
float switch 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:

51541
To reassemble the pump to version 2, both screws
need to be loosened and the brackets to be turned.
This allows both float switches 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 adjust-
ment. See the following table.
