3. Configuració i instal·lació

Proper installation is crucial for the effective operation of the thermal expansion tank. For detailed, step-by-step instructions, please refer to the official Manual d'instal·lació (PDF) provided by PROFLO.

Passos previs a la instal·lació:

1. Inspect Tank: Unpack the expansion tank and inspect it for any shipping damage.
2. Check Pre-Charge Pressure: The tank is typically shipped with a pre-charge pressure of 20 PSI. It is critical to adjust this pressure to match the incoming cold water supply pressure of your system. Use an accurate pressure gauge on the air valve (Schrader valve) located at the bottom of the tank.
3. Tanqueu el subministrament d'aigua: Locate the main water shut-off valve to your home or the shut-off valve for your water heater and turn it off.
4. Sistema de drenatge: Open a hot water faucet in your home to relieve pressure and drain some water from the hot water system.

Passos de connexió:

5. Localitza el punt de connexió: The expansion tank should be installed on the cold water supply line to the water heater, typically between the main shut-off valve and the water heater inlet.
6. Install Tee Fitting: Install a tee fitting into the cold water supply line to create a branch for the expansion tank.
7. Connect Tank: Thread the expansion tank onto the tee fitting. Ensure all connections are tight and use appropriate sealing compounds (e.g., Teflon tape or pipe dope) to prevent leaks. The tank features a .75 inch connection.
8. Tanc segur: If necessary, use a support bracket or strap to secure the tank, especially if it is installed horizontally or in a location where it could be bumped.

Post-instal·lació:

9. Sistema de recàrrega: Slowly open the main water supply valve to refill the system.
10. Aire de purga: Open hot water faucets throughout the house to purge air from the plumbing system until water flows smoothly.
11. Comproveu si hi ha fuites: Carefully inspect all connections for leaks. Tighten any leaking connections.

4. Principis de funcionament

The PROFLO PFXT12I Thermal Expansion Tank operates passively to protect your plumbing system. When water is heated, it expands. In a closed plumbing system, this expansion can lead to dangerously high pressures, potentially damaging the water heater, pipes, and fixtures.

The expansion tank contains an air-filled bladder or diaphragm. As the hot water expands, it pushes against this bladder, compressing the air inside the tank. This allows the excess volume of water to enter the tank, thereby absorbing the pressure increase and maintaining a safe operating pressure within the system. When hot water is used and the system cools, the pressure drops, and the compressed air pushes the water back out of the tank and into the plumbing system.

5. Manteniment

Regular maintenance helps ensure the longevity and proper function of your thermal expansion tank.

Comprovacions recomanades:

• Annual Pressure Check: At least once a year, check the air pre-charge pressure of the tank. Turn off the water supply to the water heater and drain a small amount of water from a hot water faucet to depressurize the system. Use a tire pressure gauge on the air valve at the bottom of the tank. The pressure should match your cold water supply pressure. Adjust with a bicycle pump or air compressor if necessary.
• Inspecció visual: Periodically inspect the tank for any signs of corrosion, leaks, or physical damage.
• Tap Test: Tap the top and bottom of the tank. If the tank is working correctly, the top should sound hollow (air-filled), and the bottom should sound solid (water-filled). If the entire tank sounds solid, the bladder may have failed, and the tank is full of water.

6. Solució De Problemes

If you experience issues with your hot water system, the expansion tank may be a contributing factor. Here are some common problems and their potential solutions:

If you are unable to resolve an issue, it is recommended to contact a qualified plumbing professional.
