Configuració i instal·lació
The LF25AUB-Z3 valve is designed for straightforward installation. Follow these general guidelines:
- Prepareu l'àrea d'instal·lació: Ensure sufficient space for the valve and access for future maintenance.
- Tancament del subministrament d'aigua: Locate and close the main water shut-off valve to your property.
- Sistema de despressurització: 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.
- Connect the Valve: 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.
- Estrènyer les connexions: Securely tighten all connections, but avoid over-tightening, which can damage threads or fittings.
- Restaurar el subministrament d'aigua: Slowly open the main water shut-off valve.
- Comproveu si hi ha fuites: 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.

Instruccions de funcionament
The Watts LF25AUB-Z3 valve is designed for automatic operation once installed and adjusted. The primary operational aspect is pressure adjustment.
- Configuració inicial: The valve is factory preset to 50 psi (345 kPa).
- Ajust de la pressió de sortida:
- A augmentar the outlet pressure, turn the adjustment screw (located at the top of the bell housing) clockwise.
- A disminuir the outlet pressure, turn the adjustment screw counter-clockwise.
- Interval de pressió: The adjustable pressure range is 25 to 75 psi (172 to 517 kPa). Do not adjust outside this range.
- Seguiment: It is recommended to use a pressure gauge downstream of the valve to accurately monitor and set the desired outlet pressure.
- Expansió tèrmica: 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.
Manteniment
Regular maintenance ensures the longevity and optimal performance of your Watts LF25AUB-Z3 valve. The design allows for easy in-line serviceability.
- Neteja del colador: 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.
- Inspecció del diafragma: The high-temperature diaphragm is a critical component. If pressure regulation becomes erratic, inspect the diaphragm for wear or damage.
- Inspecció general: Annually inspect the valve for any external damage, corrosion, or leaks.

Resolució de problemes
This section provides general guidance for common issues. For complex problems, consult a qualified plumbing professional.
| Problema | Causa possible | Solució |
|---|---|---|
| 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. |
| Low water pressure downstream | 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 | Connexions soltes, segells/juntes danyats, carcassa esquerdada. | Tighten connections. Inspect and replace seals/gaskets. If housing is cracked, replace the valve. |
