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 for the present device will reduce the danger of
possible operational malfunction and contribute to extend the life cycle of your device. Abrasive matters contained
in the liquid being discharged - such as sand, for instance - will speed up wear and tear and reduce the
performance of the unit.
As long as the pump is properly used, it will not require any maintenance. However, for reason of the particular
properties of the liquids permitted to be discharged, the suction and pressure lines should be inspected regularly
and replaced, if necessary. Please do not expose the hoses to any direct weather influence and avoid direct sun
exposure categorically. Also, check the hoses regularly for cracks and other damage. A damaged hose must not
be used any longer and is to be replaced.
To avoid any danger, any further disassembly or replacement of parts must only be done by the manufacturer or
by an authorised customer-service provider.
Frost may cause the liquid contained in the pump to freeze and thus entail considerable damage. Therefore, if
one has to reckon with temperatures likely to cause freezing, the pump has to removed from the liquid being
discharged and emptied completely. 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.
When operating the pump, please make sure that the intake of the suction line is always fully immersed in the
liquid being discharged so as to avoid air being sucked in. In this context, please bear in mind that the liquid level
will continuously drop during the process of emptying a container. The absence of liquid being discharged counts
among the most frequent causes of dry-running which can lead to considerable damage to the unit and injury by
burning.
It is recommended to avoid liquid containers being emptied right down to the bottom since this will cause the
pump to take in air and will require the entire venting process to be repeated prior to the next operation of the
pump.
The electrical pumps of the
63,'2WUDQVIHU
series 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.
MALFUNCTION
POSSIBLE CAUSE
ELIMINATION
1. The pump is not discharging
any liquid, the motor is not
running.
