Original Instructions
We hereby declare that these pumps/domestic
water works/domestic water automatic systems,
identified by type and serial number *1), meet all
relevant requirements of directives *2) and
standards *3). Technical documents for *4) - see
page 3.
This device is used for conveying clean water in
the house and garden area, for sprinkling and
watering, as a well pump, rain pump and domestic
water pump and for pumping out swimming pools,
garden ponds and water tanks.
The pump is not intended for:
- continuous operation
- industrial or commercial use
The pump is not suitable for transportation of:
- drinking water
- food
- salt water
- explosive, flammable, aggressive, or hazardous
materials (e.g. chemicals)
- liquids over 35°C
- water containing sand and liquids with an
abrasive effect
The pump is not suitable for increasing pressure: if
the pump is connected to a line that is already
pressurised then a suitable pressure regulator
should be installed upstream of this. The maximal
pressure of the system must not exceed the stated
maximum pressure of the pump under any
circumstances. It should also be borne in mind that
the inlet pressure is added to the cut-off pressure
of the pump!
This device is not designed for the use of persons
(including children) with limited physical, sensory
or mental aptitude or lack of experience and/or
knowledge.
Unauthorised modifications to the device and the
use of parts that are not tested and approved by
the manufacturer are prohibited.
All improper use of the device is regarded as non-
specified use; this can result in unpredictable
damage! The user bears sole responsibility for any
damage caused by inappropriate use.
Generally accepted accident prevention
regulations and the enclosed safety information
must be observed.
Pay attention to all parts of the text that
are marked with this symbol for your
own protection and for the protection of
your device!
WARNING – Reading the operating
instructions will reduce the risk of injury.
WARNING Read all safety warnings and
instructions. Failure to follow all safety
warnings and instructions may result in electric
shock, fire and/or serious injury.
Keep all safety instructions and information
for future reference.
Pass on your pump only together with these
documents.
Information in these operating instructions is
designated as shown below:
Danger! Risk of personal injury or
environmental damage.
Risk of electric shock! Risk of personal
injury from electric shock.
Caution! Risk of material damage.
Children, adolescents and
persons who are not familiar with
the operating instructions must not
use the device.
Children should be supervised to
ensure that they do not play with
the device.
The provisions of DIN VDE 0100-
702 and -738 must be observed
when the pump is being used in
swimming pools and garden
ponds and in the protected areas
around them.
The device must be supplied with
a rated residual current of max.
30 mA through a residual-current
device (RCD).
The device must not be used if
there are persons in the water.
The statutory water and waste
water specifications and the
provisions of DIN 1988 must be
observed when used for the
domestic water supply.
The following residual risks
essentially remain when operating
pumps and pressure vessels
(equipment-specific) – they
cannot be fully eliminated even if
safety measures have been
introduced.
4.1 Danger from the
environment!
Do not expose the device to rain.
Do not operate the device in a
damp or wet environment.
Do not use the pump in potentially
explosive locations or near
flammable liquids or gases!
4.2 Danger from hot water!
Danger! Install a check valve
at the suction connection (8) to
prevent water from flowing back
into the suction line. This can
reduce the following danger:
Hot water can cause damage and
leaks on the device and the
connection lines, allowing hot
water to escape. Danger of
scalding!
Devices with the designation
HWW...: if the shut-off pressure of
the pressure switch cannot be
reached due to poor pressure
conditions or a defective pressure
switch, the water can heat up
within the device as a result of
internal circulation.
Devices with the designation P...:
do not operate the device against
a closed discharge line for longer
than 5 minutes. Water that
circulates inside the device is
heated up.
In the event of a fault, unplug the
device from the power supply
system and allow it to cool. A
specialist must check the system
to make sure it is in perfect
working order before it can be
used again.
4.3 Risk of electric shock!
Never direct the water jet directly
at the device or other electrical
components! Risk of fatal electric
shock!
Always disconnect the device
from the power supply system
prior to installation and
maintenance tasks.
Do not touch the plug with wet
hands! Always pull on the plug and
not the power cable to disconnect
it.
Do not buckle, squeeze, drag or
drive over the power cable or
extension cables; protect them
from sharp edges, oil and heat.
4.4 Danger due to deficiencies
or faults on the device!
Check the device for possible
damage - especially the mains
cable, mains plug and electrical
components before each use.
Risk of fatal electric shock!
A damaged device must only be
reused after it has been correctly
repaired.
Do not attempt to repair the device
yourself! Only specialists are
permitted to repair pumps and
pressure vessels (equipment-
specific).
Caution! To prevent water
damage, such as flooded
rooms, caused by deficiencies or
faults on the device:
- Provide appropriate safety
measures, e.g. alarm device or
collection tank with monitoring
The manufacturer is not liable for
any damage caused by:
- Improper use of the pump.
- Overloading of the pump through
continuous operation.
- Failure to operate and store the
pump in a frost-free environment.
- Unauthorised modification of the
pump. Repairs to electrical
equipment may only be carried
out by qualified electricians!
