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.
