Assembly
Use only extension cables that are suitable
for use outdoors - minimum cross-section 1.5
mm . Cable drums should always be unrolled
2
completely.
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
Erecting the equipment
1. Prepare a flat and solid erection site.
2. Erect the machine horizontally and protected
against flooding.
3. Bolt the house water system securely at the
bolting points (Fig. A -7) if necessary.
4. The house water system must be protected
from rain and direct water jets.
ADVICE
In daily operation (automatic mode), you
must ensure, by suitable measures, that,
in the event of a fault in the equipment,
consequential damage caused by floo-
ding is excluded.
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.

Fitting the pressure line
1. Screw the connecting nipple (Fig. B -16) with
the round seal ring (Fig. B -17) into the pump
outlet (Fig. A -4).
2. Screw the elbow nipple (Fig. B -14) with seal
(Fig. B -15) onto the connecting nipple (Fig. B
-16) and turn the elbow nipple in the desired
direction.
3. Fix a pressure line (Fig. B -13) onto the elbow
nipple (Fig. B -14).
4. Open all the 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 storage diaphragm
pressure of 1.5 - 1.7 bar in the storage
vessel. Check the air pressure at the
valve on the back of the storage vessel
before commissioning.
1. If necessary, in the pressure line (Fig. B -13),
open one of the existing closing off devices
(valve, spray nozzle, water cock).
2. Slide the closing off cover valve (Fig. F -28)
on the back of the storage vessel (Fig. A -6)
upwards.
3. Check the air pressure at the valve (Fig. F -29)
with an air pump or a tyre filler, each having a
pressure indicator (pressure gauge).
4. If necessary, adjust the air pressure to 1.5 -
1.7 bar.
5. Then close the closing off cover valve on the
back of the storage vessel again.
6. The house water system can now be commis-
sioned.
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.
ADVICE
Fill the suction hose with water before
screwing in place to reduce the suction
time.
