Start up
DWS - Series | Version 1.03 11
Fig. 7: Setting up the pump
All connection lines must be absolutely leak-tight, as
leaking lines can impair the performance of the pump
and cause considerable damage. It is therefore essen-
tial to seal the threaded parts of the cables with each
other and the connection to the pump with Teflon tape.
Only the use of sealing material such as Teflon tape en-
sures that the assembly is airtight.
Avoid excessive force when tightening fittings, which
can cause damage.
When laying the connecting cables, make sure that no
weight, vibrations or tensions are applied to the pump.
In addition, the connecting cables must not be dam-
aged or have a counterfall to the pump.
8.2 Electrical connection
Power supply cables and power plugs may only be re-
placed by qualified personnel in order to avoid hazards.
Do not lift or carry the pump by the power cord, and do
not use it to disconnect the power plug from the socket.
Protect the power plug and power cord from heat, oil
and sharp edges.
9Startup
NOTE!
When operating the pump outdoors, the electrical
connections must be splash-proof. The connections
must not come into contact with water.
ATTENTION!
The electrical connection must be equipped with a
high sensitive fault-current circuit breaker (RCCB):
30 mA.
ATTENTION!
Only use an extension cable whose cross-section
and rubber sheathing correspond at least to the
connection cable of the device and are marked with
the corresponding abbreviation according to VDE.
Power plugs and couplings must be splash-proof.
WARNING!
Danger to life!
There is danger to your life if you do not follow these
rules.
- Never work with the water pump if you are under
the influence of alcohol, drugs or medications and /

Step 1: Joints of the inlet pipelines should be sealed
with the least elbows, no water can be sucked.
Step 2: Connect the inlet pipe (Pos. 7, Fig. 8) to the
pump. The inlet pipe should have an inside dia-
meter of at least 25 mm and must be bend-
proof, pressure-proof and vacuum-proof. Keep
the suction pipe as short as possible as the
pump capacity decreases with increasing
length.
Step 3: Install the inlet pipe (Pos. 7, Fig. 8) in ascending
order and with at most one bend to the pump to
avoid air inclusions.
Step 4: Place the valve (Pos. 8, Fig. 8) at the end of the
inlet pipe in the water (approx. 30 cm from the
bottom) and ensure that there is always an suffi-
cient water supply.
Step 5: Install a filter on the inlet pipe of the pump to pre-
vent entering of the solid particles in the pump.
9.2 Connection of the pressure pipe
The pressure pipe (Pos. 4, Fig. 8) transports the liquid
from the pump to the extraction point. To avoid flow los-
ses, it is recommended to use a pressure pipe with at
least the same diameter as the pressure connection of
the pump.
Install the pressure pipe correctly at the pump and at
the respective tapping point.
ATTENTION!
The suction pipe must be installed in such a way
that it cannot exert any mechanical forces or distor-
tions on the pump.
ATTENTION!
When pumping dirty liquids, install a intake filter to
protect the pump from sand and dirt.
NOTE!
It is recommended to install a non-return valve to
prevent water backflow when the pump is switched
off.
ATTENTION!
Make sure that there is a sufficient distance (30 cm)
between the inlet pipe and the ground and shores to
prevent damage from the sand or stones being suc-
ked in.
ATTENTION!
The pressure pipe must be installed in such a way
that it cannot exert any mechanical forces or distor-
tions on the pump. All fittings should be sealed with
thread sealing tape.
ATTENTION!
Incorrect installation and use of parts that are not
resistant to internal pressure may cause the pres-
sure line to burst during operation. This may cause
injury due to liquid escaping from the line!

Operation
DWS - Series | Version 1.03 13
10 Operation
10.1 Fill the pump with water
Step 1: Remove the plug (Pos. 5,Fig. 8) from the filler
neck and pour in clean water until the pump is
completely filled with water.
Step 2: Close the filler neck (Pos. 5,Fig. 8)again with the
screw plug.
Step 3: Start the pump and make sure that there is no
water leakage.
DANGER!
Danger to life due to electric shock!
There is danger to life when in contact with live com-
ponents. Switched on electrical components can
cause uncontrolled movements and lead to serious
injuries.
- Disconnect the mains plug before starting any adju-
stments to the water pump.
ATTENTION!
The device must be correctly installed before use. It
must also be checked that the filter elements are
correctly installed and powerful.
The device should only be operated, mounted,
repaired and transported on firm, level ground.
Make sure that the electrical data indicated on the
engine block match those of the mains to which the
water pump is to be connected, and that the water
pump power plug is plugged into the socket.
ATTENTION!
Always disconnect the power plug from the power
outlet before handling the disconnected water
pump.
Always check the supply cable for damage such as
cracks or signs of aging. If necessary, replace the
cable before further use.
The replacement of a defective power cord must be
carried out by the technical service or by qualified
personnel.
When using an extension cord, make sure that it has
the same cable dimension as the pump power cable
and avoid contact of the cables with liquids or co
ductive surfaces.
WARNING!
Before putting the device into operation, make sure
that the voltage stated on the rating plate corre-
sponds to the mains voltage.
WARNING!
Before starting the engine, the pump must be com-
pletely filled with water.
ATTENTION!
Make sure that the pump is properly placed and
ready for use. Check whether all hose connections
are firmly bolted and undamaged.
ATTENTION!
Before starting the motor, the pump must be com-
pletely filled with water.
Dry running can damage the pump.
NOTE!
When commissioning for the first time, it is essential
to make sure that the pump housing is completely
deaerated, even with self-priming pumps - that is,
filled with water. If this venting is omitted, the pump
does not suck in the pumped liquid. It is recom-
mended, but not necessary, in addition to deaerate
the suction line or to fill it with water.
ATTENTION!
Dry running the pump without pumping water must
be avoided as lack of water will cause the pump to
overheat. This can lead to considerable damage to
the device. In addition, there is very hot water in the
system, so there is a risk of scalding. With the pump
hot, unplug the power cord and allow the system to
cool.

Care, maintenance and repair
10.2 Starting the water pump
Step 1: Close all hoses by the water pump, fill the pump
with clean water.
Step 2: Switch on the pump at the ON / OFF switch.
Step 3: After filling, open existing shut-off devices in the
pressure line, e.g. a faucet so that the air can es-
cape during the intake process.
Step 4: Check the suction lines for possible water leaks.
11 Care, maintenance and repair
11.1 Care by cleaning
The house water system should always be kept in a
clean condition.
Clean the pre-filter at regular intervals, remove the
cover, put out the filter vertically and rinse it under clean
water.
Always keep the cooling fins clean and free.
ATTENTION!
Make sure that the pump is properly placed and
ready for use. Check if all hose connections are
tight.
ATTENTION!
For safety reasons, never use the pump for corrosive
liquids such as acid. To avoid corrosion, do not
pump chemicals or other aggressive substances.
ATTENTION!
Do not allow the pump to run for more than 10 min-
utes with the discharge line closed as this may
cause damage to the pump due to water overheat-
ing.
NOTE!
The house water system DWS 1105 is equipped with
an additional dry-running protection and pre-filter.
The dry-running protection switches the pump off as
soon as no water can be pumped.
The pre-filter filters efficiently sand and similar parti-
cles from the liquid, minimizing wear and extending
the service life of the pump.
ATTENTION!
Before maintenance work, the pump must be dis-
connected from the mains. If it is not disconnected
from the mains, u.a the risk of unintentional starting of
the pump can occur.
NOTE!
The warranty does not cover the parts of the water
pump that have been treated by the operator as
being abusive or negligent. For a full warranty, the
operator must operate the water pump as descri-
bed in the instructions.
For proper operation of the water pump, regular
adjustments must be made.
ATTENTION!
Never use solvents to clean plastic parts or painted
surfaces. A surface release and consequential da-
mage may occur.
Use protective gloves!
NOTE!
If the device is not used for a long time, the water in
the pump should be drained. The pump body, impel-
ler and bracket should be cleaned and coated with
anti-corrosion oil before storing in a well-ventilated
dry place.

carrying out any maintenance or repair work.
Regular maintenance and careful care reduce the risk
of possible malfunctions and help to extend the service
life of your device. To prevent possible malfunctions, it is
advisable to regularly check the pressure generated
and the energy consumption. The pre-pressure (air
pressure) in the pressure vessel should also be chec-
ked regularly. To do this, disconnect the pump from the
mains supply and open a consumer in the pressure
line - e.g. a water tap - so that the hydraulic system is no
longer under pressure.
If water flows out of the boiler valve, the membrane is
defective and must be replaced. A high-quality food-
safe diaphragm is available as a spare part. If the de-
vice is not used for a longer period of time, the pump
and pressure vessel should be emptied using the de-
vices provided for this purpose.
