25 mm (1")- and 19 mm (3/4") hoses connected with a connection
nipple
(2)
must be fastened, for example with a GARDENA Hose
Clamp Art. 7192 / 7191.
1. Only for Art. 1768 [ Fig. A4 ]: Put the float switch locking
(A)
on the
pump connector
(1)
.
2. Screw connection nipple
(2)
onto the pump connection
(1)
.
(With 25 mm (1") hoses, first disconnect the connection nipple
(2)
at
<
.)
3. Push the hose onto the connection nipple
(2)
and fix e. g. with
a GARDENA Hose Clamp Art. 7192 / 7191.
Connect hose via the GARDENA Connection System [ Fig. A5 ]:
19 mm (3/4")- / 16 mm (5/8") and 13 mm (1/2") hoses can be connected
via the GARDENA Connection System.

2. Connect the hose via the relevant GARDENA Connection System.
To connect the floating suction unit [ Fig. A6 / A7 ]:
v
Connect the vacuum-proof suction hose
(8)
with G1" connector
(e. g. Art. 1411) and fasten it to the other end.
The suction hose
(8)
must be cut to length so that it does not form loops
during operation and no air is sucked in.
For trouble-free operation (system ventilation), the non-return valve
(9)
must be removed from the floating suction unit.
v
Unscrew the filter basket
(10)
with pliers.
The non-return valve
(9)
is not necessary in this application as the pumps
have a non-return valve.
The suction hose should have a length of 50 cm.
The pump must be located in the cistern when the suction is floating.
A suction in vertical position when the pump is hanging is not possible.
In the horizontal position the float switch is not functional and the dry
run safety device is inactive.
v
Switch the pump on and off manually and monitor it.
If no flow can be detected, the pump must be switched off again.
3. OPERATION
DANGER! Risk of injury!
Injury when the product starts accidentally.
v
Disconnect the product from the mains before you connect,
adjust or transport the product.
To pump water [ Fig. O1 ]:
The pump must always be submerged in the well or water reservoir
with the rope provided. For the pump to be primed, the pump must be
submerged at least 100 mm. So that the filter does not become dirty,
the pump should be fixed at least 30 cm above the ground.
1. Attach the rope
(3)
securely to the lug
(4)
.
2. Submerge the pump in the well or water reservoir via the rope
(3)
.
3. Secure the rope
(3)
.
4. With deep wells or shafts (from approx. 5 m), route the connection
cable
(5)
along the rope
(3)
with clips.
5. Connect the pump to the mains.
The pump starts approx. 3 sec. after connecting the connection cable.
The pump is ready for operation.
Only for Art. 1768:
Automatic mode with float switch [ Fig. O2 ]:
So that the pump automatically switches off when there is no
liquid to pump, the Float Switch
(6)
must be able to freely move
on the surface of the water.
Due to the integrated non-return valve, the pressure is maintained in the
hose until water is drawn via the hose.
To adjust the Cut-in and Cut-out Height [ Fig. O3 ]:
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
(A)
.
• The shorter the length of cable between the float switch
(6)
and
the float switch lock
(A)
, the lower the cut-in height and the higher
the cut-out height.
v
Push the cable of the float switch
(6)
into the opening in the float 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. O4 ]:
The pump remains permanently in operation because the float
switch is bypassed. This deactivates the dry-running protection
of the pump.
1. Push the float switch
(6)
onto the float switch locking
(A)
with the cable
downwards.
2. 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.
Only for Art. 1771 / 1773:
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. Art. 1771: 2,2 bar / Art. 1773: 2,9 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
pressure 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.
Use of washing machines:
Upon completion of the low quantity water supply cycle in washing
machines, the 60-minute operating interval of the low quantity pro-
gramme is automatically reset to normal operation of the pump and
allows a trouble-free use of the washing machine for > 60 minutes.
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
(7)
should
be cleaned at regular intervals.
After pumping dirty water, the filter
(7)
must be cleaned immediately.
