MALFUNCTION
2. The motor is running, but the
pump is not discharging any
liquid.
3. The pump stops after a short
time of operation because the
thermal motor protection feature
has triggered.
4. The pump stops because the
anti dry-running feature is
activated (red "Error" indicator
lights up).
5. The pump cuts in and out too
frequently.
6. The pump does not cut out.
7. The pump does not reach the
desired pressure.
11. Warranty
The present device was manufactured and inspected according to the latest methods. The seller warrants for
faultless material and workmanship in accordance with the legal regulations of the country in which the device
was purchased. The warranty period begins with the day of the purchase and is subject to the provisions below:
Within the period of warranty, all defects which are to be attributable to defective materials or manufacturing will
be eliminated free of charge. Any complaints are to be reported immediately upon their detection.
The warranty claim becomes void in the case of interventions undertaken by the purchaser or by third parties.
Damage resulting from improper handling or operation, incorrect setting-up or storage, inappropriate connection
or installation or Acts of God or other external influences are excluded from warranty.
Parts being subject to wear and tear, such as the pump wheel (impeller) and mechanical shaft seals are excluded
from warranty.
All parts were manufactured using maximum care and high-quality materials and are designed for a long lifecycle.
It should be understood, however, that the wear and tear depends on the kind of use, the intensity of use and the
internals of maintenance. Complying with the installation and maintenance information contained in the present
operating instructions will therefore considerably contribute to a long lifecycle of these wearing parts.
In case of complaints, we reserve the option of repairing or replacing the defective parts or replace the entire
device. Replaced parts will pass into our property.
Claims for liquidated damages are excluded unless they are caused by wilful acts or negligence on the side of the
manufacturer.

POSSIBLE CAUSE
1. The pump housing is not filled with liquid.
2. Air penetrates into the intake line.
3. Suction height and/or discharge height too
great.
4. The difference in height between the
electronic pump control and the point of
withdrawal, limited to max. 15 m by the
preset value, has been exceeded.
1. The electrical supply does not correspond
to the information given on the type plate.
2. Pump or intake line are blocked by solids.
3. Liquid is too viscous.
4. Temperature of liquid or environment is
too high.
1. Refer to section 2.2.
1. Permanent loss of very small quantities of
liquid (e.g. dripping water tap, leaking hoses
or connecting elements).
2. Electronic pump control is defective.
1. Permanent loss of large quantities of
liquid.
2. Electronic pump control is defective.
1. Refer to section 2.2.
2. Worn pump wheel.

ELIMINATION
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.
