Original instructions.
For safety reasons, children and young
people under 16 as well as anyone who is
not familiar with these operating instructions
should not use the product. Persons with reduced
physical or mental abilities may use the product only
if they are supervised or instructed by a responsible
person. Children must be supervised to ensure that
they do not play with the product. Never operate the
product when you are tired, ill or under the influence
of alcohol, drugs or medicine.
Intended use:
The Irrigation Valves are intended solely for outdoor
use for fully automatic control of individual irrigation
systems. It is a benefit to arrange a watering system
into separate sections in case of varying watering
needs for different plant areas or if there is insuffi-
cient water available for simultaneous operation
of the entire watering system.
The Irrigation Valve is installed upstream in the
watering system (e.g. Pop-up Sprinklers;
Micro-Drip-System), for example, in the ground.
Please note:
Compliance with the enclosed operating
instructions provided by GARDENA is a pre-
requisite for proper use of the Irrigation Valve.
Fig. 9 V:
The Irrigation Valve 1251 forms part of an irrigation
system in conjunction with the Programming Unit
1242 and the Control Unit 1250.
Fig. 24 V:
The Irrigation Valve 1278 forms part of an irri-
gationsystem in conjunction with the Watering
Controller 1276.
The Irrigation Valve must only be used
in conjunction with the – 9 V Control
Units; Radio Receivers/24 V Watering Con-
troller – approved by GARDENA.

1. SAFETY
IMPORTANT!
Read the operator’s manual carefully before
use and keep for future reference.
vPlease observe the notes on safety in the
operating instructions.
9 V and 24 V products are not interchange-
able.
Blocking the Irrigation Valve:
vIn the case of dirty water, the GARDENA
Central Filter Art. 1510 must be installed
upstream in the watering system.
Water pressure:
The function of your watering system depends
on the available water pressure. Therefore, care
should be taken not to overlap watering cycles of
the various watering circuits and to ensure that the
watering circuits you have planned will be supplied
with sufficient water at an adequate pressure.
Please refer to the planning instructions in the
special brochure entitled “Watering Systems –
Sprinkler System Planning Guide” available from
GARDENA.
DANGER!
This product makes an electromagnetic field while
it operates. This field may under some conditions
interfere with active or passive medical implants.
To decrease the risk of conditions that can possibly
injure or kill, we recommend persons with medical
implants to speak with their physician and the
medical implant manufacturer before you operate
the product.
DANGER!
Small parts can be easily swallowed. There is
also a risk that the polybag can suffocate toddlers.
Keep toddlers away when you assemble the
product.

2. INITIAL OPERATION
If the Irrigation Valve is installed below ground
level, it must be installed in a sturdy and step-
proof valve mount 1(valve box) e.g. GARDENA
Art. 1254/1255/1290/1292.
Install the valve mount [Fig. I1/I2]:
1. Draw up a plan (see e.g. Fig. I3).
Additional information is provided in the
GARDENA Sprinkler System Planning Guide
which is available from your GARDENA dealer.
2. For underground installation, place a layer of
coarse gravel 2underneath the valve mount 1.
This ensures proper drainage of the box.
3. Install the valve box with the top edge of the box
at ground level.
This avoids damage when mowing the lawn.
Please refer to the relevant operating instructions
for information on how to install the Irrigation
Valves in GARDENA Valve Boxes V1 and V3.
Installing the Irrigation Valve without
a Valve Box [Fig. I4]:
The integrated solenoid valve works only correctly
with the Irrigation Valve connected in flow direction.
CAUTION!
Flow direction!
vPay attention to the flow direction (arrows)
when installing the Irrigation Valve 3.
vSeal the screw connections with PTFE sealing
tape, Art. 7219.
Connecting GARDENA Connecting pipes 8
(2700/2701/2704/2705/2718) or other com-
mercially available connecting pipes:
1. Screw a GARDENA Connector 72763
(1" = 25 mm)/2769 (5/4" = 32 mm) into the
Irrigation Valve 3.
2. Connect the GARDENA connecting pipes 8
or other commercially available connecting pipes
(25 mm/32 mm).
Connect Soil Moisture Sensor or Rain Sensor
electronic (optional) [Fig. I5]:
In conjunction with the programmed watering time,
the moisture level of the soil or the natural precipi-
tation can be taken into account for each Irrigation
Valve.
14
EN

When a sufficient moisture content of the soil is
reached, a programme may be interrupted or
activation of a programme may be suppressed.
1. Place the Soil Moisture Sensor 9in the area to
be irrigated
– or –
the Rain Sensor electronic (if necessary with
an extension cable) outside of the area to be
irrigated.
2. 9 V: Plug the connector 0into the sensor socket
of the Control Unit.
24 V: Insert plug 0in the sensor connection
of the Watering Control System Art. 1276
(see Operating Instructions Art. 1276).
Conventional installation [Fig. I6]:
If using Art. 2750/2751/2752/2753/2755 the
points marked with an arrow must be sealed with
sealing tape (e.g. Art. No. 7219).
3. OPERATION
Adjusting valve control [Fig. O1]:
Fully Automatic Control:
vSet selection lever qto “AUTO/OFF”.
Programme-controlled water flow to the watering
system according to the programming in the
Control Unit/Radio Receiver.
An automatically opened valve cannot be closed
manually.
Manual Control:
vSet selection lever qto “ON”.
Permanent water flow, independent of the
programming.

4. STORAGE
To put into storage/Winter storage:
GARDENA Irrigation Valves are intended for outdoor
use and are only frost-proof to a limited extent. The
only way to protect your Irrigation Valves completely
is to remove the valves before the frosty season
begins. Alternatively, you can drain the pipeline sys-
tem upstream and downstream of the Irrigation
Valve.
Emptying the pipeline system UPSTREAM of
the valve [Fig. O1]:
1. Turn off the tap and disconnect the hose
between the tap and the GARDENA Water
Connection Point Art. 2722/Art. 2795.
This allows the air to flow freely and the supply
line can be drained using the drain valve inte-
grated in the Connecting Point. This requires that
the Connecting Point be installed deeper in the
ground than the Irrigation Valve.
2. If the watering system is directly connected to the
water tap, turn off the water supply and open the
venting tap.
3. Set the selection lever qof all valves to the “ON”
position.
4. If you are using the GARDENA Valve Box V3,
make sure you open the integrated drain cap.
Emptying the pipeline system DOWNSTREAM
of the valve:
Requirement: The Drainage Valve must be
installed deeper than or at the same depth as
the Irrigation Valve.
vInstall a GARDENA Drainage Valve Art. 2760
immediately after the valve.
The system is drained automatically via the the
GARDENA Drainage Valve.
VIf neither of these requirements is fulfilled,
the valve must be removed and stored in
a place safe from frost.
Disposal:
(in accordance with RL2012/19/EC)
The product must not be disposed of to
normal household waste. It must be dis-
posed of in line with local environmental
regulations.
Important! Dispose of the product through or
via your municipal recycling collection centre.
