n The intake valve should be so far immersed in the
water that the pump cannot run dry even if the
water level falls.
n If the intake line is not air-tight, the intake of air
will hinder the intake of water.
8. Pressure line connection
n The pressure line (should be at least 19 mm
(3/4“)) must be connected to the pumpʼs pressure
line connection (33,3 mm (R1)) either directly or
via a threaded nipple.
n A 13 mm (1/2“) pressure hose can also be used
with the appropriate screw connections, of course,
but this will reduce the delivery rate.
n All shut-off devices (spray nozzles, valves etc.) in
the pressure line must be fully opened when
priming so that any air in the intake line can
escape.
9. Starting up
n Set up the pump on flat and firm ground.
n Attach the intake line ready for use.
n Unscrew the water filler screw (3) and remove the
coarse filter (6) together with the non-return valve
(7) as shown in Figure 2. Now you can fill the pump
housing with water. Filling the intake line
accelerates the priming process.
n Assemble in reverse order.
n Plug into the mains.
n All shut-off devices in the pressure line (spray
nozzles, valves etc.) must be fully opened when
priming so that any air in the intake line can
escape.
n Depending on the suction height and the amount
of air in the intake line, priming can take anywhere
between 30 seconds and 5 minutes. If it takes
longer than this, the pump should be refilled with
water.
n If the pump is removed again after use, it must
always be refilled with water whenever it is
connected up and used again.
9.1 Operating the flow switch:
You can select one of the four operating modes with
the MODE button.
POWER ON mode:
The equipment is in standby mode.
EVER ON mode:
The equipment will run continuously. Important: Never
let the equipment run against pressure over a longer
period (without drawing water). Danger of
overheating!
AUTOMATIC mode:
L = The equipment is drawing water (pump is running)
P = The equipment is building up pressure (e.g. the
water tap is closed) and then switches off
automatically.
TIME mode:
1. TIME NOW (current time): First press the SET
button, then you can enter the time with the SET
and MODE button. Confirm your entry by
pressing the CHECK button.
2. TIME ON (switch-on time): Proceed as described
under TIME NOW.
3. TIME OFF (switch-off time): Proceed as
described under TIME NOW.
4. Check TIME ON and OFF again, then confirm by
pressing the CHECK button.
The programming is now completed. Now check that
for example the water tap is always opened at the
programmed time.
10. Maintenance instructions
n The pump is basically maintenance free. To
ensure a long service life, however, we
recommend regular checks and care.
Warning!
Before every servicing, switch off the pump
and remove the plug from the socket.
n If the pump is not going to be used for a long time
or has to be removed for the winter months, rinse
it out with water, empty it completely and allow it
to dry.
n If there is a risk of frost, the pump must be
emptied completely.
n After long stoppages, make sure the rotor turns
correctly by briefly switching the pump on and off.
n If the pump becomes blocked, connect the
pressure line to the water line and remove the
intake hose. Open the water line. Switch on the
pump several times for approx. 2 seconds. Most
blockages can be removed in this way.
10.1 Cleaning the coarse filter insert
n Clean the coarse filter insert at regular intervals,
and replace it if necessary.
n Remove the coarse filter screw and coarse filter
together with the non-return valve .
n Do not use abrasive cleaning agents or petrol to
clean the coarse filter and the non-return valve.
