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.
4. Check the cause; eliminate the reason for the
jamming of the pump.
5. Please contact the customer service department.
6. Refer to section 2.2 and 2.3 and chapter 9.3.
"Cutting out in the case of dry running or absence of
water"
1. Fill the pump housing with liquid (please refer to
"Putting into operation" section).
2. 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.
3. Change the arrangement of the installation so that
the suction height and/or discharge height will not
exceed the max. value.
4. The switch-on pressure of the electronic pump
control is to be increased. This must only be done
by a qualified provider of plumber or electrician
services.
1. Please use a device complying with GS (German
technical supervisory authority) to check the voltage
of the lines of the connection cord (safety
information to be observed!).
2. Remove possible congestion.
3. Pump may not be suitable for this liquid. If feasible,
the liquid should be thinned.
4. Make sure that the temperature of the liquid being
pumped and the environment do not exceed the
max. admissible values.
1. Refer to section 2.2. + 2.3.
1. Eliminate leakages.
2. Please contact the customer service department.
