Maintenance And Troubleshooting - TIP EXTREMA 500/13 IX Mode D'emploi

troubleshooting" section. Please note that the pump can only be operated with liquids > 50°C for a short period of
time (see Technical data).

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. To remove tenacious dirt, the foot of the pump (8)
can be removed by loosening the screws located at the bottom of the pump. To avoid any hazard, any further
disassembly as well as the replacement of parts must only be done by the manufacturer or a by an authorised
service provider. 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.
