Assembly

Damaged or brittle extension cables must not
be used.
Check the condition of your extension
cable each time you start to use the
equipment.
ASSEMBLY
CAUTION!
The unit will not function correctly if the
draw-off point is 15 m higher than the
unit.
Erect the unit
1. Prepare a flat solid area for erection.
2. Erect the unit horizontally and where it will not
be flooded.
The unit must be protected from the rain
and direct water jet impingement.
In day-to-day
mode) you must take measures to ex-
clude the possibility that flooding of the
room occurs as a result of malfunctions
on the unit.
Connect the suction line
1. Select the length of the suction line (Fig. B
-14) so that the house water system cannot
run dry. The suction line must always be at
least 30 cm under the surface of the water.
2. Connect the suction line. Make sure that the
connection does not leak, without damaging
the thread.
We recommend using flexible hoses at
the pump inlet (Fig. A -10). This prevents
mechanical tension or pressure from
being exerted on the house water sys-
tem.
3. Always lay the suction line with an uphill gra-
dient.
If the suction height is more than 4 m, you
must use a suction hose having a diame-
ter greater than 1". We recommend the
use of an AL-KO suction unit with suction
hose, suction filter and flow-back stop.
Ask your expert dealer.

Fitting the pressure line
1. Screw the connecting nipple (Fig. B -12) with
the round seal ring (Fig. B -13) into the pump
outlet (Fig. A -4).
2. Screw the elbow nipple (Fig. B -10) with seal
(Fig. B -11) onto the connecting nipple (Fig. B
-12) and turn the elbow nipple in the desired
direction.
3. Fix a pressure line (Fig. B -8) onto the elbow
nipple (Fig. B -10).

STARTUP

On initial commissioning the display (Fig.
E -24) shows all information in English.
Select the desired language with the
MODE button (-25) and confirm with the
SET button (-26).
Filling the unit
CAUTION!
Dry running will destroy the pump! The
pump must be filled with water up to the
overflow before each use so that it can
draw water immediately.
1. Open the filling screw (Fig. A -3) with the filter
key.
2. Fill with water via the filling screw until the
marl on the pump housing is reached.
3. Screw the filling screw back in position.
In order to reduce the suction time, fill the
suction hose with water before screwing
in position.
Initial start-up of the unit
1. Open a closing-off device (valve, spray
nozzle, water tap) in the pressure line.
2. Insert the mains plug on the connection cable
into the plug socket.
The pumps starts to pump.
3. When no more air comes out with the water,
close the closing off device in the pressure
line.
The pump switches off when the flow
stops, after building up pressure.
The domestic water pump is ready for
operation. The display shows AUTO O
and FLOW O.
