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

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.
