Sąranka ir diegimas
The LF25AUB-Z3 valve is designed for straightforward installation. Follow these general guidelines:
- Paruoškite montavimo vietą: Ensure sufficient space for the valve and access for future maintenance.
- Išjunkite vandens tiekimą: Locate and close the main water shut-off valve to your property.
- Slėgio mažinimo sistema: Open a faucet at the lowest point in your plumbing system to drain water and relieve pressure.
- Identify Flow Direction: The valve body has an arrow indicating the direction of water flow. Install the valve so that the arrow points in the direction of water flow from the main supply into your property.
- Prijunkite vožtuvą: The valve features NPT female union inlet and NPT female outlet connections. Use appropriate fittings (PEX, CPVC, Quick-Connect, or NPT threaded) and sealing compounds (e.g., PTFE tape or pipe dope) to ensure watertight connections.
- Priveržkite jungtis: Securely tighten all connections, but avoid over-tightening, which can damage threads or fittings.
- Atkurti vandens tiekimą: Slowly open the main water shut-off valve.
- Patikrinkite, ar nėra nuotėkių: Inspect all connections for any signs of leaks. Tighten as necessary.
- Verify Pressure Setting: Use a pressure gauge to confirm the outlet pressure. The valve is factory set to 50 psi.

Naudojimo instrukcijos
The Watts LF25AUB-Z3 valve is designed for automatic operation once installed and adjusted. The primary operational aspect is pressure adjustment.
- Pradinis nustatymas: The valve is factory preset to 50 psi (345 kPa).
- Adjusting Outlet Pressure:
- Į padidinti the outlet pressure, turn the adjustment screw (located at the top of the bell housing) clockwise.
- Į mažėti the outlet pressure, turn the adjustment screw counter-clockwise.
- Slėgio diapazonas: The adjustable pressure range is 25 to 75 psi (172 to 517 kPa). Do not adjust outside this range.
- Stebėjimas: It is recommended to use a pressure gauge downstream of the valve to accurately monitor and set the desired outlet pressure.
- Šiluminis plėtimasis: The built-in bypass feature allows for reverse flow when outlet pressure exceeds inlet pressure by approximately 10 psi due to thermal expansion, protecting the system.
Priežiūra
Regular maintenance ensures the longevity and optimal performance of your Watts LF25AUB-Z3 valve. The design allows for easy in-line serviceability.
- Sieto valymas: The valve includes a removable integral stainless steel strainer. Periodically inspect and clean the strainer to prevent debris buildup, which can affect performance.
- Seat Module Replacement: The valve features a replaceable seat module. If the valve fails to hold pressure or exhibits consistent leaks, the seat module may need replacement. Consult the Watts website or a qualified plumber for replacement parts and procedures.
- Diafragmos apžiūra: The high-temperature diaphragm is a critical component. If pressure regulation becomes erratic, inspect the diaphragm for wear or damage.
- Bendra apžiūra: Annually inspect the valve for any external damage, corrosion, or leaks.

Trikčių šalinimas
This section provides general guidance for common issues. For complex problems, consult a qualified plumbing professional.
| Problema | Galima priežastis | Sprendimas |
|---|---|---|
| High water pressure downstream | Valve not regulating, debris in valve, incorrect adjustment. | Adjust pressure screw counter-clockwise. Inspect and clean strainer. Check for damaged seat module or diaphragm. |
| Žemas vandens slėgis pasroviui | Valve set too low, debris in valve, insufficient inlet pressure. | Adjust pressure screw clockwise. Inspect and clean strainer. Verify main water supply pressure. |
| Water dripping from relief port | Thermal expansion, debris in bypass, worn seat. | This can be normal due to thermal expansion. If excessive, check for debris in the bypass or a worn seat module. Consider installing an expansion tank if not already present. |
| Visible leaks from valve body | Atsilaisvinusios jungtys, pažeisti sandarikliai, įtrūkęs korpusas. | Tighten connections. Inspect and replace seals/gaskets. If housing is cracked, replace the valve. |
