Noise reduction, as no vibrations are
transferred to pipes in the domestic wa-
ter system.
In case of small leaks, the pump does
not switch as often.
Note
To facilitate subsequent emptying and
pressure release of the system, we recom-
mend the installation of a stop-cock be-
tween pump and pressure line.
(not included in delivery)
By closing the shut-off valve when empty-
ing the pump you can prevent water from
escaping from the pressure line.
Install a pressure equalization container
(see special accessories) in case of in-
creased pressure reductions due to leakag-
es in the domestic system (pump switches
on regularly without water removal).
Insert the mains plug into the socket.
Switch on the appliance using the ON/
OFF switch.
Optimum convenience with operation in
the automatic mode.
Illustration
In order to reduce the suction time, lift
the delivery hose approx. 1m.
Wait till the pump sucks in and trans-
ports water uniformly
Note
The ON/OFF switch can also be conveni-
ently operated with your foot.
Note
In the automatic mode the pump switches
off at a flow rate of < 60 l/h.
ṇ Caution
Lacking water supply is recognised by the
appliance. If no water is drawn and deliv-
ered within 4 minutes during start-up in the
manual mode or within 3 minute in the au-
tomatic mode, the pump shuts off. The LED
"Error on the suction side" is illuminated on
the display.
Switch off the appliance using the On/
Off switch.
Disconnect the main plug from the
socket.
ƽ DANGER
Turn off the appliance and remove the
mains plug prior to any care and mainte-
nance works.
Open the connected shutoff valves to relief
pressure and reclose them. The system is
free of pressure.
Rinse the pump after every use if you
use to transport water with additives.
Check pre-filter regularly for dirt. If it is vis-
ibly dirty, proceed as follows:
Illustration
Unscrew the lid of the filling nozzle.
Remove the pre-filter and the built in
backflow valve and clean them under
flowing water.
Illustration
When inserting the pre-filter (with check
valve) in the filler neck, mind the cor-
rect installation position (notch). It
must be possible to insert the pre-filter
easily and without exertion of force.
ṇ Caution
Only use grease that is free from mineral oil
for seals.
The appliance is maintenance free.
