ASSEMBLY
Setting up the equipment
1. Prepare a flat and solid location.
2. Erect the unit horizontally and safe from the
risk of flooding.
➯
The unit must be protected from the rain
and direct water jets.
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 -15)
with
the round seal ring
(Fig. B -16)
into the pump
outlet
(Fig. A -3)
.
2. Screw the elbow nipple
(Fig. B -13)
with seal
ring
(Fig. B -14)
onto the connecting nipple
(Fig. B -15)
and turn the elbow nipple in the
desired direction.
3. Fix a pressure line
(Fig. B -12)
to the elbow
nipple
(Fig. B -13)
.
4. Open all closing off devices (valves, spray
nozzles, water cock) in the pressure line.
STARTUP
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.
ADVICE
In order to reduce the suction time, fill the
suction hose with water before screwing
in position.
Switch the pump on
1. Open all closing off devices (valve, spray
nozzle, water cock) in the pressure line.
2. Insert the mains plug on the connection cable
into the plug socket.
3. Switch the garden pump on at the on / off
switch.
CAUTION!
Do not allow the pump to run against a
closed off pressure line.
Switch pump off
1. Switch the garden pump off at the on / off
switch after use.
2. Close all the closing off devices in the pres-
sure line.
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.
