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.
ADVICE
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.
Connecting the suction line
1. Select the length of the suction line (Fig. B
-17) to make sure that the house water sys-
tem cannot run dry. The suction line must al-
ways be at least 30 cm under the surface of
the water.
2. Connect the suction line. Make sure that the
connection is tight, but do not damage the
thread.
We recommend using flexible lines at the
pump inlet (Fig. A -10). This ensures that
pressure or tension on the house water
system cannot be exerted.
3. If the water has a small amount of sand in it,
a pre-filter must be fitted between the suction
line and the pump inlet. Ask your expert dea-
ler about this.
4. Always lay the suction line with an upward
gradient.
ADVICE
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.
Mounting the pressure line
1. Screw the connecting nipple (Fig. B -13) with
the round seal ring (Fig. B -14) into the pump
outlet (Fig. A -3).
2. Screw the elbow nipple (Fig. B -11) with seal
ring (Fig. B -12) onto the connecting nipple
(Fig. B -13) and turn the elbow nipple in the
desired direction.
3. Fix a pressure line (Fig. B -10) to the elbow
nipple (Fig. B -11).
4. Open all closing off devices (valves, spray
nozzles, water cock) in the pressure line.

STARTUP

Check the air pressure in the storage vessel.
CAUTION!
The house water system must only be
commissioned with a diaphragm storage
vessel pressure of 1.5 - 1.7 bar. Before
commissioning, check the air pressure at
the valve on the back of the storage ves-
sel.
1. Open the cover on the back of the storage
vessel.
2. Check the air pressure at the valve with an air
pump or a tyre pump with pressure indicator.
3. If necessary, correct the air pressure to 1.5 -
1.7 bar.
4. Then close the cover again on the back of the
storage vessel.
5. The house water system can now be commis-
sioned.
Fill the house water system
CAUTION!
Before using the house water system
each time, you must fill it with water up
to the overflow so that it can draw water
immediately. The pump will be destroyed
if it runs dry.
1. Open the filling screw (Fig. A -2).
Not with INOX
2. Use the filling screw to fill up with water until
the pump housing is full.
3. Screw the filling screw back in place.
Switch the pump on.
1. Open one of the closing off devices (valve,
spray nozzle, water cock) in the pressure line
(Fig. B -10).
2. Insert the mains plug on the connection cable
into the plug socket.
The pump starts to convey.
3. When there is no more air in the water that
comes out , close the closing off device in the
pressure line.
The pump switches off automatically af-
ter the switch-off pressure has been
reached. The house water system is re-
ady for use.
