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 230V AC 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 pump, please pull the mains plug off the socket.
The electrical pumps are equipped with an integrated thermal motor protection feature. In the case of overload,
the motor will switch off independently and on again after cooling down. For possible causes and their elimination,
please refer to the “Maintenance and troubleshooting” section.
8. Maintenance and troubleshooting
Prior to carrying out any maintenance work, the pump must be separated from the electrical
mains. If you fail to separate the unit from mains, there is a risk of an inadvertent start of the
pump.
We decline any liability for damage caused by inappropriate repair attempts. Any damage
caused by inappropriate repair attempts will avoid all warranty claims.
Observing the conditions of use and the ranges of application of the present device will reduce the risk of possible
operational malfunction and contribute to extend the lifetime of your unit. Sand and other abrasive matters
contained in the liquid discharged will speed up the process of wearing and tearing and accelerate the drop in
performance.
If the unit is operated properly, it will not require any maintenance. Where applicable, you may clean the hydraulic
part from sediments and dirt. This can be done by counter-flushing the unit with clear water using a hose to be
connected through the pressure port of the pump. This pump is additionally equipped with a filter mat, which
prevents dirt from clogging the pump chamber and possibly damaging it. The filter insert should be cleaned
regularly
– depending on the degree of soiling.
Water left in the pump may freeze in case of frost and thus cause considerable damage. Therefore, the pump
must be removed from the liquid being discharged and fully drained when temperatures are below the freezing
point of the liquid. Please store the pump in a dry, frost-protected place.
In the case of malfunction, you should first of all check whether it was caused by an operating error or some other
reason which cannot be attributed to a defect of the device - for instance a power failure.
The list below shows some possible malfunctions of the device, possible causes and tips on their elimination. All
the measures referred to may only be carried out with the pump being separated from the electrical mains. If you
yourself feel unable to eliminate any of these malfunctions, please contact the customer service department or
your point of sales. Any repair beyond the scope specified below must only be performed by qualified staff.
Please bear in mind that all warranty claims will become void in the case of damage caused by inappropriate
repair attempts, and that we decline any liability for any ensuing damage.
MALFUNCTION
POSSIBLE CAUSE
ELIMINATION

1. Please use a device complying with GS (German
technical supervisory authority) to check for the
presence of voltage (safety information to be
observed!). Please verify the correct position of
the plug.
2. Separate the pump from the electrical mains,
allow the system to cool down, eliminate cause.
3. Please contact the customer service department.

possibly motion of floating switch
restricted, floating switch defective.
1. Remove possible congestion.
2. Remove possible congestion.
3. Start pump several times so that the entire air will
be driven out.
4. Make sure that the minimum suction level is not
fallen short of; if necessary, make sure that it can
move freely; in the case of a defective floating
switch, please contact customer service.
3. Water quantity
discharged by pump is
inadequate.
1. Refer to section 2.1.
2. Refer to section 2.2.
3. Worn pump wheel.
