Intended use
The GARDENA Pressure Regulator is intended to reduce the output pressure in irrigation systems of private gardens and allotments to 3.1 bar maximum, as well as to protect the irrigation systems from contamination.
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.
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).
- On each side, screw a connector (art. 2762) ⑥ finger-tight onto the pressure regulator ⑤.
- Place the pressure regulator ⑤ between the connectors 6 , the filter ②, ③, ④ pointing upwards. Make sure to install the pressure regulator ⑤correctly in the direction of the water flow indicated by the arrow ⑬ on the pressure regulator ⑤.
- On each side, connect the connecting pipes ⑦ of the irrigation system to the connectors (art. 2762) ⑥.
Make sure to insert the connecting pipes ⑦into 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.
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.
Example of a sprinkler system containing a pressure regulator installed below ground:
To perform a test run
Before installing the irrigation system below ground, we recommend that you carry out a test run above ground:
- Lay out the irrigation system above ground.
- Cut the connecting pipes to the required length.
- Install the irrigation system above ground.
- 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 connecting pipes are inserted into the connectors as far as they will go.
To install the system below ground
-
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). -
Fill coarse gravel ⑪ on a surface of approx. 20 x 20 x 8 cm at the place where you want to install the valve shaft ⑪.
-
On each side, connect a connector (art. 2763) ⑧ to the connecting pipes ⑦ of the irrigation system) ⑧ .
Make sure to insert the connecting pipes ⑦ into the connectors ⑧ by 6 cm. ⑦.
→ 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.
-
Place the valve shaft ⑩ on the coarse gravel layer ⑪.
Make sure that the top edge of the closed lid ⑫ of the valve shaft ⑩ is even with the ground. -
Open the lid ⑫ of the valve shaft ⑩.
-
On each side, screw a connector (art. 2758) ⑨ finger-tight onto the connectors (art. 2763) ⑧.
-
Place the pressure regulator ⑤ with the filter ②, ③ and ④ pointing upwards in the valve shaft ⑩ at the level of the side inlets.
Make sure to install the pressure regulator ⑤correctly in the direction of the water flow indicated by the arrow ⑬ on the pressure regulator ⑤. -
On each side, screw a connector (art. 2758) ⑨ finger-tight onto the male threads of the pressure regulator ⑤.
-
Close the lid ⑫ of the valve shaft ⑩.
-
Fill the hole with soil, and compact it carefully.
MAINTENANCE
To flush the pressure regulator
We recommend flushing the pressure regulator once a month.
-
Close the water supply.
Remove the cap ④. -
Open the water supply for approx. 5 seconds.
-
Close the water supply
This cleans the filter ② of coarse dirt.
→ If the filter is still dirty, repeat the last two steps. -
Mount the cap ④.
-
Open the water supply for further operation.
To clean the pressure regulator
We recommend cleaning the pressure regulator manually once a year.
- Close the water supply.
- Open the housing ring ③.
- Remove the filter ② carefully.
- Rinse the filter ② thoroughly with clean water.
- Insert the filter ② into the pressure regulator.
- Mount the housing ring ③ and tighten it hand-tight.
- Open the water supply for further operation.
STORAGE
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.
Drainage with the drain valve set (art. 2770-20)
- Close the water supply.
- Connect the drain valve set (art. no. 2770-20) according to its operator‘s manual.
- 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.
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.
- Close the water supply.
- Open the irrigation valves in the valve shaft to depressurize 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.
