MALFUNCTION
POSSIBLE CAUSE
ELIMINATION
1. The pump is not discharging
any liquid, the motor is not
running.
1. No current.
2. Thermal motor protection feature has
triggered.
3. The capacitor is defective.
4. The pump wheel is blocked.
5. Anti dry running protection is activated
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. Eliminate blocking of pump wheel.
5. Follow instructions as in section 8.
2. The motor is running, but the
pump is not discharging any
liquid.
1. The intake openings are clogged.
2. The pressure line is clogged.
3. Kinks or similar disturbances in the
connection lines.
4. Check valve (non-return valve) is blocked
or damaged.
5. Inlets are not immersed in the liquid to be
discharged.
6. The pump head of the pump referred to in
the technical data is exceeded.
1. Remove possible congestion.
2. Remove possible congestion.
3. Remove the kinks or other disturbances in
the connection lines.
4. Eliminate blocking of the check valve (non-
return valve) or replace, if damaged.
5. Immerse the intake inlets of the intake line
into the liquids to be discharged.
6. Modify the installation so that the suction
height will not exceed the maximum value.
3. The pump stops after a short
time of operation because the
thermal motor protection feature
has triggered.
1. The electrical supply does not correspond
to the information given on the type plate.
2. Please refer to items 2.1 to 2.5.
3. Liquid is too viscous.

5. Pump is running dry.
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. Please refer to items 2.1 to 2.5.
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 does not exceed the
max. admissible value.
5. Eliminate causes of dry-running.
4. Intermittent or irregular
operation.
1. Please refer to items 2.1 to 2.5.
2. Refer to section 3.3.
3. Refer to section 3.4.
4. Mains voltage out of tolerance.
5. Motor is defective.
1. Please refer to items 2.1 to 2.5.
2. Refer to section 3.3.
3. Refer to section 3.4.
4. Make sure that mains voltage matches that
indicated on the type plate.
5. Please contact the customer service
department.
5. Water quantity discharged by
pump is inadequate.

10. 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.
