Maintenance And Troubleshooting - SPIDO BF 100/50 Mode D'emploi D'origine

GB
9. PREFILTER (NOT INCLUDED)
Abrasive matters contained in the liquid being dis-
charged - such as sand - accelerate wear and tear
and reduce the performance of the pump. When
discharging liquids containing such matters, the in-
stallation of a prefilter is recommended. This useful
accessory it will efficiently filter sand and similar par-
ticles out of the liquids, thus minimise wear and tear
and extend the lifetime of the pump.
The proper functioning of the filter should be checked
on a regular basis. If necessary, please clean replace
the filter mesh.

10. 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.
Regular maintenance and thorough care will reduce
the danger of possible malfunction and contribute to
an extension of the lifetime of your unit.
If you notice that the pump runs
continuously without stopping, beyond one
minute after closing the valves: check that
the pressure reached on the pressure gauge is higher
than the switch stop setting.
YES > contactor problem> contact your dealer
NO > disconnect the pump from the mains and see
if the pressure drops by itself while the valves are
closed.
YES> the pump is not in question and there is a leak
on the suction column that is not watertight (return
to the well - leak on pipe or check valve missing or
defective) or backflow.
NO> the pump is worn or clogged> contact your
dealer.
If you suddenly notice that your booster has
ran continuously without interruption (more
than 30 minutes), to avoid any risk of burns
or breakage of an accessory:
1- Open the taps to relieve the pressure in the circuit
2- Turn off the pump and allow it to cool
3- Check the installation of the pump: suction line
sealing and other accessories, proper operation of
the pressure switch.
To prevent possible malfunction, it is recommended
to check the occurring pressure and the energy
consumption at regular intervals. Also, the pre-
pressure (atmospheric pressure) in the pressure
tank should be checked regularly. To do so, please
separate the pump from mains, then open any
consumer component in the pressure line - for
instance, a water tap - to release the pressure from
the hydraulic system. Subsequently, unscrew the
protection cap of the tank valve (17). On the tank
valve, please use a pressure gauge to check the
pre-pressure. It should read cut-in pressure -0.2b
(ex: 2-0,2=1,8bar), otherwise it has to be corrected.
If any water is leaking out of the tank valve, the
membrane is defective and should be replaced.
If the device is not in use over some extended period
of time, both the pump and the pressure tank should
be emptied using the devices provided for this
purpose. Water left in the pump may freeze in case of
frost and thus cause considerable damage. 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.
