1. Scavo: Dig a hole approximately 14 inches in diameter and 12 inches deep at the desired location for the sprinkler.
2. Preparazione della base: Place about 3 inches of pea gravel and fine sand at the bottom of the hole to provide a stable base and protect the pipe connection.
3. Collegamento del tubo: Connect the sprinkler to your irrigation lateral line. A 90-degree threaded/glued elbow is often used for direct PVC connections. Ensure a watertight seal. Note that a standard USA garden hose may require a specific adapter to connect to the 3/4-inch NPT thread.
4. Posizionamento: Seat the sprinkler into the prepared hole, ensuring it is flush with the ground level. The ribbed body helps secure the sprinkler in place.
5. Riempimento: Carefully backfill the remainder of the hole with soil, tightly packing it around the sprinkler body to prevent tilting.
6. Regolazione direzionale: Once installed, the sprinkler body cannot be rotated. However, the spray head can be easily positioned to face the correct direction by turning it clockwise. The pop-up mechanism is designed to allow this adjustment without overtightening.

4.2 Protezione dal gelo

For regions subject to freezing temperatures, it is recommended to install a drainage valve within the pipe network. This allows for proper draining of the system, making it frost-proof and preventing damage to the sprinkler and pipes.

5. Operativo

5.1 Adjusting Spray Area and Range

The Gardena OS 140 features 16 flexible precision nozzles for even water distribution. The spray pattern and range are adjustable to suit your specific lawn or garden area.

1. Accessing Adjustments: To adjust the spray settings, gently pull off the top cover of the sprinkler head. This will expose the adjustment levers.
2. Regolazione della larghezza: Use the two levers to independently adjust the left and right sides of the spray width. This allows for precise shaping of the rectangular area.
3. Length/Distance Adjustment: A flow rate valve is present to adjust the distance of the spray. This control allows you to set the forward and back limits of the oscillation, effectively controlling the casting range (2-15 meters).
4. Regolazione del volume: The sprinkler also features a volume regulation option for fine-tuning the overall water output, which can further influence the spray distance and intensity.

5.2 Water Pressure Requirements

The sprinkler requires a minimum operating pressure of approximately 28 PSI to ensure the pop-up mechanism functions correctly and to achieve optimal spray performance. The spring mechanism is robust, ensuring the sprinkler retracts fully when the water supply is off.

6. Manutenzione

6.1 Pulizia del filtro

The Gardena OS 140 is equipped with an integrated dirt filter to prevent clogging. Regular cleaning of this filter is essential for maintaining optimal performance.

1. Accesso al filtro: To access the filter, unscrew the sprinkler head counter-clockwise. This can be done without special tools.
2. Rimozione del filtro: Once the head is removed, the filter will be accessible. The spring mechanism remains secured in the bottom part of the unit.
3. Pulizia: Rinse the filter under running water to remove any accumulated dirt or debris. For stubborn clogs, a soft brush may be used.
4. Rimontaggio: Reinsert the clean filter and screw the sprinkler head back on clockwise until secure.

6.2 Rimessaggio invernale

Before the first frost, ensure your irrigation system, including the OS 140 sprinkler, is properly drained to prevent damage from freezing water. If a drainage valve is installed, activate it to clear water from the lines. Consult your irrigation system's overall winterization guidelines.

7. Risoluzione Dei Problemi

• Sprinkler not popping up: Check water pressure. Ensure it meets the minimum 28 PSI requirement. Inspect for clogs in the filter or nozzles.
• Uneven spray pattern: Clean the nozzles and filter. Verify that the spray width and distance adjustments are correctly set.
• Reduced spray distance: Check water pressure. Clean the filter. Ensure the flow rate valve is fully open if maximum distance is desired.
• Leaks around the head: Ensure the sprinkler head is securely screwed onto the body. Check for any damage to the O-rings or seals.
• Sprinkler not retracting: Inspect for debris obstructing the pop-up mechanism. The spring is strong, so obstructions are the most likely cause.
