5. ການຕິດຕັ້ງ

Proper installation is crucial for the optimal performance and longevity of your pressure regulator valve. It is recommended that installation be performed by a licensed plumber.

ຂັ້ນ​ຕອນ​ການ​ຕິດ​ຕັ້ງ​:

1. ປິດການສະຫນອງນ້ໍາ: Locate the main water shut-off valve for your property and turn it off.
2. ລະບົບ Depressurize: Open a faucet at the lowest point in your system to drain water and relieve pressure.
3. ເລືອກສະຖານທີ່: Install the regulator on the main water supply line after the main shut-off valve and before any branch lines. Ensure there is sufficient space for future maintenance.
4. Orient Valve: The valve has an arrow indicating the direction of water flow. Install the valve so the arrow points in the direction of water flow into your property.
5. ສ້າງການເຊື່ອມຕໍ່: Use appropriate plumbing practices to connect the 1-inch FNPT Union x FNPT ends of the regulator to your plumbing system. Apply thread sealant (e.g., PTFE tape or pipe dope) to all threaded connections. Tighten securely but do not overtighten.
6. Install Pressure Gauge (Optional but Recommended): Install a pressure gauge downstream of the regulator to monitor the regulated pressure.
7. ຟື້ນຟູການສະຫນອງນ້ໍາ: Slowly open the main water shut-off valve. Check for leaks at all connections.
8. ລ້າງອາກາດ: Open faucets throughout the property to purge air from the system until water flows smoothly.

6. Operation and Pressure Adjustment

The Watts 1 LFU5B-LP-Z3 valve comes factory-set to a nominal pressure, but it can be adjusted within its specified range (10 to 35 psi) to meet your specific needs.

Adjusting Outlet Pressure:

1. Ensure Water Flow: It is best to adjust the pressure while water is flowing at a low rate (e.g., a partially open faucet) to get an accurate reading.
2. ຊອກຫາ Screw ປັບ: The pressure adjustment screw is located at the top of the valve.
3. Decrease Pressure: ຫັນສະກູປັບ ກົງກັນຂ້າມກັບເຂັມໂມງ to decrease the outlet pressure.
4. ເພີ່ມຄວາມກົດດັນ: ຫັນສະກູປັບ ຕາມເຂັມໂມງ to increase the outlet pressure.
5. ຕິດຕາມຄວາມກົດດັນ: Use a pressure gauge installed downstream of the regulator to monitor the outlet pressure as you make adjustments.
6. ທົດສອບແລະກວດສອບ: After adjustment, close all faucets and observe the static pressure on the gauge. Open a faucet again to verify the dynamic pressure. Repeat adjustments as necessary until the desired pressure is achieved.

7. ບໍາລຸງຮັກສາ

Regular inspection and maintenance can extend the life of your pressure regulator valve and ensure consistent performance.

• ການກວດກາປະຈຳປີ: Annually check the valve for any signs of leaks, corrosion, or damage.
• ກວດ​ສອບ​ຄວາມ​ກົດ​ດັນ​: Periodically check the outlet pressure with a gauge to ensure it remains at the desired setting. Fluctuations may indicate internal wear.
• ທໍາຄວາມສະອາດ: If the water supply contains sediment, the internal screen (if applicable) may need cleaning. This typically requires shutting off the water, depressurizing the system, and disassembling the lower portion of the valve. Refer to a qualified plumber for this procedure.
• ຊິ້ນສ່ວນທົດແທນ: Use only genuine Watts replacement parts if internal components need to be replaced.
