3. OPERATION
Automatic operation [ Fig. O1 ]:
If the water level reaches the ON sensor 3, the pump
automatically switches on. Depending on water volume
and environment, it can take 1 to 3 minutes until pump-
ing out commences.
Immediate delivery is possible given the following
switch-on level of the ON sensor:
• from 5 mm for Art. 1783 / 1785 without non-return
valve
• from 30 mm for Art. 1783 / 1785 with non-return valve
• from 95 mm for Art. 1797 / 1799
As soon as the water level falls below the OFF sensor
4
,
the pump is automatically switched off (the pump con-
tinues to run for approx. 10 seconds).
1. Stand the pump on a firm surface
– or –
use a rope attached through the bore hole in the carry-
ing handle 5 to immerse the pump in a well or shaft.
2. Plug the power cable 6 into a mains socket.
Adjust switch-on and switch-off height [ Fig. O2 ]:
The switch-on and switch-off height (see 7. TECHNICAL
DATA) can be adjusted for automatic mode. The relevant
sensor pin defines the height of the water level.
Set switch-on height ON:
v
Push ON sensor
3
to the required switch-on height.
Switch-on height of the pump in automatic mode.
Set switch-off height OFF:
v
Push OFF sensor
4
to the required switch-off height.

Manual operation [ Fig. O3 / O4 ]:
The pump remains in operation continuously. The ON
sensor
3
is locked in manual position and bridged via
the contact
7
.
1. Push OFF sensor
4
and ON sensor
3
right down so
that the ON sensor
3
touches the contact
7
.
2. Stand the pump on a firm surface
– or –
use a rope attached through the bore hole in the carry-
ing handle
5
to immerse the pump in a well or shaft.
3. Plug the power cable
6
into a mains socket.
Only for the submersible pumps:
Flat suction / Normal operation [ Fig. O5 ]:
Flat suction [ Fig. O6 ]:
v
Turn the 3 swivel feet
8
180° to 1 mm.
Normal operation [ Fig. O7 ]:
v
Turn the 3 swivel feet
8
180° to 5 mm.
The residual water level of approx. 1 mm is only reached
during flat suction in the manual operation mode.
The following connection kits are required for 13 mm
to 19 mm connections:
13 mm (¹⁄₂"): GARDENA Pump Connection Set
Art. 1750
16 mm (⁵⁄₈"): GARDENA Tap Connector
GARDENA Standard Hose Connector
Art. 18202
and
Art. 18216
19 mm (³⁄₄"): GARDENA Pump Connection Set
Art. 1752
Best results in delivery capacity are achieved when using
38 mm (1 ¹⁄₂") hoses.
Connecting the hose [ Fig. I5 ]:
The universal fitting
2
allows you to connect all the hoses
listed in the previous table.
1. Cut off nipples of the universal fitting
2
, which are not
needed, o match the hose connection.
2. Only for the submersible pumps Art. 1783 / 1785:
Insert the non-return valve
ß
V
supplied into the universal
connector 2 with the word UP pointing upwards.
3. Screw the universal fitting
2
onto the pump.
4. Connect the hose to the universal fitting
2
.
We recommend 38 mm (1 ¹⁄₂") 25 mm (1") hoses, in
addition to be fixed with a GARDENA Hose Clamps
Art. 7192 (for 25 mm) and Art. 7193 (for 38 mm).
Only for the submersible pumps Art. 1783 / 1785:
For flat suction we recommend using a 13 mm (¹⁄₂") or
16 mm (⁵⁄₈") hose. The non-return valve
ß
V
prevents the
water flowing back through the hose. The max. delivery
height will only be achieved without the non-return valve.
Only for 13 mm (¹⁄₂") hose:
The universal fitting
2
can also be equipped with
a GARDENA Regulator Valve Art. 977 so that the
contents of the outlet line do not flow back through
the pump after pumping. The Regulator Valve can be
ordered from your GARDENA dealer.
