Translation of original operating instructions
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. Intermittent or irregular
operation.
5. Water quantity discharged
by pump is inadequate.
6. The pump does not cut in
or out.
9. 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.
POSSIBLE CAUSE
1. The intake openings are clogged.
2. The pressure line is clogged.
3. Air penetrates into the pump body.
4. The min. suction level was fallen
short of; possibly incorrect setting of
the floating switch, motion of floating
switch restricted, floating switch
defective.
5. Check valve (non-return valve), if
present, is blocked or defective.
1. The electrical supply does not
correspond to the information given
on the type plate.
2. Pump or intake openings are blocked
by solids.
3. Liquid is too viscous.
4. Temperature of the liquid is too high.
5. Pump is running dry.
1. Pump wheel obstructed by solid
matters.
2. Refer to section 3.3.
3. Refer to section 3.4.
4. Mains voltage out of tolerance.
5. Motor or pump wheel defective.
1. Refer to section 2.1.
2. Refer to section 2.2.
3. Worn pump wheel.
1. Floating switch cannot move freely.
2. Incorrect setting of floating switch.
3. Floating switch defective.

ELIMINATION
1. Remove possible congestion.
2. Remove possible congestion.
3. Start pump several times so that the
entire air will be driven out.
4. Make sure that the minimum suction
level is not fallen short of; if
necessary, adjust floating switch
properly or make sure that it can
move freely; in the case of a defective
floating switch, please contact
customer service.
5. Eliminate blocking of the check valve
(non-return valve) or replace, if
damaged.
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 does not exceed
the max. admissible value.
5. Eliminate causes of dry-running.
1. Remove solids.
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.
1. Refer to section 2.1.
2. Refer to section 2.2.
3. Please contact the customer service
department.
1. See that floating switch can move
freely.
2. Correct floating switch settings.
3. Please contact the customer service
department.
