3. If the water carries a small amount of sand
you must fit a pre-filter between the suction
line and the pump inlet. Ask your expert dea-
ler about this.
4. Always lay the suction line with an upwards
gradient.
ADVICE
If the suction height is more than 4m, 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
Filling the garden pump
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. B -8).
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.
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.
ADVICE
If nothing is drawn up for longer than
180 seconds, the garden pump automa-
tically switches to "Fault" and turns off.
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
CAUTION!
The pump must be isolated from the
mains before any maintenance and ser-
vice work. Remove the mains plug from
the plug socket.
Flushing the pump
After conveying swimming pool water containing
chlorine or fluids that leave a residue the pump
must be flushed out with clear water.
Remove blockages
1. Isolate the unit from the mains and secure
against switching on again.
2. Remove the suction hose from pump inlet.
