1. ASSEMBLY

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 filter 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).

1. On each side, screw a connector (art. 2762)

2. Place the pressure regulator

between the connectors

Make sure to insert the connecting pipes

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 different 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.

1.2.1 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

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
