1. Open the filling screw 

(Fig. A -3)

 with the filter

key 

(Fig. C -19/A)

.

2. Fill  with  water  via  the  filling  screw  until  the

pump housing 

(Fig. A -2)

 is full.

3. Screw the filling screw in.

Switching the pump on

1. Open one of the closing off devices (e.g. water

cock) in the pressure line.

2. Insert the mains plug on the connection cable

into the plug socket.

➯

The pumps starts to feed.

3. When no more air comes out with the water,

close  the  closing  off  device  in  the  pressure

line.

➯

The pump switches off automatically af-

ter the switch-off pressure has been re-

ached. The house water system is ready

for operation.

➯

The LED displays are off.

➯

If water is being fed, just the LED display

PUMP ON lights up.

Initial commissioning

In  the  initial  commissioning,  the  LED  displays

PUMP ON and the LED display FLOW CONTROL

flashes.

ADVICE

If no water is being drawn up via the suc-

tion line after approx. 90 seconds, the dry

running  protection  system  switches  the

pump  off  and  the  LED  display 

ALARM

lights up. Check for leaks in the suction

line,  the  filter  glass  and  all  screwed  fit-

tings,  push  the 

RESET  button

  and  re-

peat the initial commissioning process.

Switch the pump off

1. Remove the mains plug from the socket
2. Close  one  of  the  closing  off  devices  (valve,

spray nozzle, water cock) in the pressure line

(Fig. B -10)

.

ADVICE

If no suction takes place within a period

of  180  seconds,  the  garden  pump  au-

tomatically  goes  to  "fault"  condition  and

switches 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

Check the air pressure in the storage vessel

CAUTION!

Check  the  air  pressure  in  the  storage

vessel at regular intervals. It must not ex-

ceed  1.5  bar  (see  Section  "Commissio-

ning:  Checking  the  Air  Pressure  in  the

Storage Vessel").

Cleaning the pump

ADVICE

After  conveying  swimming  pool  water

containing chlorine or fluids that leave a

residue,  the  pump  must  be  flushed  out

with clear water.

1. Isolate  the  unit  from  the  mains  and  secure

against switching on again.

➯

The pump stops automatically.

2. Flush the pump out with clear water.
3. Insert the mains plug into the plug socket.
4. Switch  the  house  water  system  on  with  the

on /off switch 

(Fig. A -6)

.

➯

The pump starts automatically.
