1. ASSEMBLY
7
You can install the pressure regulator above or below ground. We recommend installing the pressure
regulator below ground, and centrally in front of the valves in order to protect downstream components
from excessive operating pressure. Additionally, the integrated lter protects the irrigation system from
contamination.
1.1. To install the pressure regulator above ground
In case of an installation above ground, you need one GARDENA Connector 25 mm x 1“ female
thread (art. 2762) per side in order to connect the pressure regulator to the GARDENA Connecting
Pipes of 25 mm (Art. 2700 / 2701 / 2718).
Example of a sprinkler system containing a pressure regulator installed below ground:

1.2.1 To perform a test run
Before installing the irrigation system below ground, we recommend that you carry out a test run
above ground:
1. Lay out the irrigation system above ground.
2. Cut the connecting pipes to the required length.
3. Install the irrigation system above ground.
4. Open the water supply to check the irrigation system for leaks.
If the irrigation system is tight, you can install it below ground.
If the irrigation system is not tight, check that all connections are made correctly, e.g. that the con-
necting pipes are inserted into the connectors as far as they will go.
1.2.2 To install the system below ground
3. On each side, connect the connecting pipes
of the irrigation system to the connectors (art.
2762) 6.
Make sure to insert the connecting pipes
7
into the connectors 6 by 6 cm.
After a few centimetres you will feel a resistance (sealing ring). Push the connecting pipe in even
further until it is stopped. This ensures a tight connection.
1.2. To install the pressure regulator below ground
In case of an installation below ground, you need two dierent connectors per side in order to connect
the pressure regulator to the GARDENA connecting pipes of 25 mm (Art. 2700 / 2701 / 2718):
• the GARDENA 1‘‘x1‘‘ connectors (art. 2758)
• the GARDENA connectors 25 mm x 1‘‘ male thread (art. 2763)
In case of an installation below ground, we also recommend using the valve shaft (art. 1290) to have
better access to the pressure regulator.

1. Prepare the hole in the ground that will receive the valve shaft.
Make sure that the hole is approximately 31 cm deep (the height of the valve shaft plus the layer of
coarse gravel).
2. Fill coarse gravel
the valve shaft
on a surface of approx. 20 x 20 x 8 cm at the place where you want to install

2.1.
To ush the pressure regulator
We recommend ushing the pressure regulator once a month.
1. Close the water supply.
2. Remove the cap
.
3. Open the water supply for approx. 5 seconds.
4. Close the water supply
This cleans the lter
of coarse dirt.
If the lter is still dirty, repeat the last two steps.
5. Mount the cap

6. Open the water supply for further operation.
2.2. To clean the pressure regulator
We recommend cleaning the pressure regulator manually once a year.
1. Close the water supply.
2. Open the housing ring

3.1. To put into storage
The pressure regulator as well as the irrigation system must be cleared of water before the frost period.
We recommend the use of the Drain Valve Set art. no. 2770-20.
3.1.1 Drainage with the drain valve set (art. 2770-20)
1. Close the water supply.
2. Connect the drain valve set (art. no. 2770-20) according to its operator‘s manual.
3. Drain the irrigation system with a bicycle pump or an air compressor according to the operator‘s
manual of the drain valve set.
The water drains out of the system.
3.1.2 Drainage with drain valves installed (art. 2760-20)
Notice:
The drain valve art. no. 2760-20 must be installed at the lowest point of the irrigation system.
1. Close the water supply.
2. Open the irrigation valves in the valve shaft to depressurise the irrigation system.
Now the water drains from the system through the drain valves.
Also observe the instructions for draining irrigation valves, valve shafts and sprinkler systems.
