Filling the house water system
CAUTION!
Before commissioning, the house water
system must always be filled up to the
overflow with water, so that it can draw
water immediately. If the pump runs dry
it will be destroyed.
Fill the suction hose with water before
ADVICE
screwing in place to reduce the suction
time.
1. Open the filling screw (Fig. A -3) with the filter
key (Fig. C -19/A).
2. Fill with water via the filling screw until the
pump housing (Fig. A -2) is full.
3. Screw the filling screw in.
Switching the pump on
1. If necessary, in the pressure line (Fig. B -11)
open one of the existing closing off devices
(valve, spray nozzle, water cock).
2. Insert the mains plug on the connection cable
into the plug socket.
The pumps starts to feed.
3. When no more air comes out with the water,
close the closing off device in the pressure
line.
The pump switches off automatically af-
ter the switch-off pressure has been re-
ached.
The house water system is ready for ope-
ration.
When switching on via the pressure
switch the display shows NORMAL X
and PRESSURE together with the actual
pressure.
Initial commissioning
Only on initial commissioning, the display shows
NORMAL X and PRESSURE.
If no water is drawn up via the suction
ADVICE
line (Fig. B -17) in approx. 90 seconds,
the dry running protection switches off
the pump, and the display shows ALARM
and SUCTION SIDE. Check the suction
line, the clear sight cover (Fig. A -1) and
all the screwed fittings for leaks, press
the RESET button and carry out the in-

Switching the pump off
1. Remove the mains plug from the plug socket.
2. Close all the closing off devices (valves, spray
nozzles, water cock) in the pressure line.
The pump switches off automatically
ADVICE
when the set switch-off pressure is
achieved.
CAUTION!
Danger of injury from hot water
In extended use against the closed pres-
sure side (>10 min.), the water in the
pump can be severely heated up and can
be emitted in an uncontrolled manner!
Isolate the unit from the mains and allow
the pump and water to cool down. Start
the unit again only after all the faults have
been rectified!
The risk of injury from hot water can arise if:
the installation is not correct
the pressure side is closed off
there is a lack of water in the suction line, or if
the pressure switch is defective.
Procedure
1. Isolate the unit from the mains and allow the
pump and water to cool down.
2. Check the unit, the installation and water le-
vel.
3. Start the unit again only after all the faults
have been rectified!

MAINTENANCE AND CARE

Check the air pressure in the storage vessel
CAUTION!
Check the air pressure in the storage
vessel at regular intervals. It must not ex-
ceed 1.5 bar (see Section "Commissio-
ning: Checking the Air Pressure in the
Storage Vessel").
CAUTION!
If the display shows the information
ALARM and REFILL 1.5 BAR, you need
to top up the air in the diaphragm stor-
age vessel. When the correct pressure is
achieved, th display shows ALARM and
AIR PRESSURE OK.
