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.
Possible cause
Elimination
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.
Separate the pump from the electrical
mains, allow the system to cool down,
eliminate cause.
Please contact the customer service
department.
Check the cause, eliminate the reason for
the jamming of the pump.
Please contact the customer service
department.
Fill the pump housing with liquid (please
refer to "Putting into operation" section).
Check to make sure that :
a.) the connection points of the intake
line are tight.
b.) the inlet opening of the intake line
including the check valve (non-return
valve) are immersed into the liquids
being discharged.
c.) the check valve (non-return valve)
with the filter is tight and not jammed.
d.) no siphons (i.e. permanently liquid-
filled loops), kinks, counter-slopes or
narrow spots are present along the
intake lines.
Change the arrangement of the
installation so that the suction height
and/or discharge height will not exceed
the max. value.
