Automatic mode with float switch [ Fig. O3 ]:
So that the pump automatically switches off when there is no
liquid to pump, the Float Switch
on the surface of the water.
To adjust the Cut-in and Cut-out Height [ Fig. O4 ]:
The maximum cut-in height and minimum cut-out height
(see 7. TECHNICAL DATA) can be adjusted by pushing the float
switch wire into the float switch lock.
• The shorter the length of cable between the float switch
float switch lock
(7)
, the lower the cut-in height and the higher the
cut-out height.
v Push the cable of the float switch
switch lock
(A)
.
CAUTION!
In order to ensure that the float switch is able to switch on and
off, the cable length between the float switch and the float switch
lock must be at least 10 cm.
Manual operation [ Fig. O5 ]:
The pump remains permanently in operation because the float
switch is bypassed. This deactivates the dry-running protection of
the pump.
(6)
1. Push the float switch
onto the float switch locking
downwards.
2. Stand the pump on a firm surface – or – immerse the pump in a well
or shaft using a rope attached to the pump.
3. Connect the pump to the mains.
Attention! The pump begins operating immediately.
The minimum residual water depth (see 7. TECHNICAL DATA) is only
achieved in manual mode because the float switch already switches off
the pump before this when in automatic mode.
Only for Art. 1766:
Automatic mode:
The pump automatically switches off as soon as no more water is
retrieved.
Due to the integrated non-return valve, the pressure is maintained in
the hose until water is drawn via the hose.
When water is drawn via the hose (the pressure in the hose falls below
approx. 1,5 bar), the pump switches on automatically.
Low quantity program and leakage warning:
Leakage warning:
The flow control switches off automatically as soon as no more water is
drawn. In the event of leakage on the pressure side (e.g. leaking pressure
hose or tap) switches the pump on and off at short intervals. If the pump
is switched on and off more frequently than 7 x in 2 min. (with a leakage
< 6 l/h), the pump switches off completely. When the leakage on the pres-
sure side is eliminated, the pump must be unplugged and plugged in
again in order to be operational again.
Low quantity program:
To prevent the pump from switching off earlier when used with low quan-
tity of water (e. g. drip irrigation), the leakage warning is only activated after
60 minutes.
Switching the pump on and off cyclically during the low quantity
program has no effect on the service life of the pump.
For continuous drip irrigation:
If the low quantity program is to be used for more than 60 minutes, the
irrigation must be disrupted for at least 5 minutes before the end of
the 60 minute period. The low quantity program can then be used for
a further 60 minutes.

4. MAINTENANCE
DANGER! Risk of injury!
Injury when the product starts accidentally.
v Disconnect the product from the mains before you maintain
the product.
To clean the filter [ Fig. M1 ]:
In order to ensure continuous trouble-free operation, the filter
be cleaned at regular intervals.
After pumping dirty water, the filter
(7)
1. Turn the filter
1/4 turn clockwise and remove it (bayonet lock).
(7)
2. Clean the filter
under running water.
(7)
3. Re-install the filter
in the opposite sequence.
The pump must not be operated without the filter.
To flush the pump:
After pumping chlorinated water, the pump must be flushed.
1. Pump lukewarm water (max. 35 °C), possibly adding a mild cleaning
agent (e. g. detergent) until the pumped water runs clear.
2. Remove residuals according to the waste disposal laws applicable in
your area.
5. STORAGE
To put into storage:
The pump is not frost-proof!
The product must be stored away from children.
1. Disconnect the pump from the mains.
2. Unscrew the telescopic tube / pressure hose.
3. Open the Shut-Off Valve of the telescopic tube completely.
4. Hold the pump in the upright position and let the water in the pump
run out.
Only for Art. 1766: Turn the pump upside down until no more water
runs out.
5. Clean the pump (see 4. MAINTENANCE).
6. Store the pump and the telescopic tube in a dry, enclosed and frost-
free place.
Disposal:
(in accordance with RL2012/19/EC)
The product must not be disposed of to normal household waste.
It must be disposed of in line with local environmental regulations.
IMPORTANT!
v Dispose of the product through or via your municipal recycling
collection centre.
6. TROUBLESHOOTING
DANGER! Risk of injury!
Injury when the product starts accidentally.
v Disconnect the product from the mains before you trouble-
shoot the product.
Problem
Possible Cause
Pump is running,
Air cannot escape, because
but doesn't deliver
the pressure line is closed.
(Possible kink in the pressure
hose.)
Shut-Off Valve is closed.
Air in suction foot.
Filter is clogged.
Water level below minimum
water level when put into
operation.
(7)
should
(7)
must be cleaned immediately.
Remedy
v Open the pressure line
(e. g. shut-off valve, delivery
units).
v Open the Shut-Off Valve
v Wait for about 60 seconds
until the pump has vented;
if necessary, turn off and
then on again.
v Clean the filter
(see 4. MAINTENANCE).
v Submerge the pump deeper.
