5. Setup and Installation

Follow these steps for proper installation of your new air relief valve assembly:

1. Preparation: Ensure your pool pump is turned off and all pressure has been released from the filter system.
2. Remove Old Valve: Carefully unscrew and remove the existing air relief valve from the filter. Note any O-rings or seals that may be present.
3. Assemble New Valve (if necessary): The new valve assembly may come in two parts: the valve body and the pressure gauge. Apply Teflon tape (included with some models) clockwise to the threads of the pressure gauge before screwing it securely onto the valve body.
4. Install New Valve: Apply a small amount of silicone lubricant to the O-ring at the base of the new valve assembly. Carefully screw the new valve assembly into the designated port on your filter tank. Tighten by hand until snug, being careful not to overtighten.
5. Check for Leaks: Turn on your pool pump. Once the system is running, check for any leaks around the newly installed valve.

6. Operating Instructions

The air relief valve is essential for proper filter operation and safety. Follow these guidelines for use:

• Releasing Air: Before opening the filter for cleaning or maintenance, or if you notice air in your pump system, turn off the pump. Then, manually open the air relief valve by rotating the top cap to the 'OPEN' position. You will hear a hissing sound as air escapes. Keep the valve open until a steady stream of water emerges, indicating all air has been purged. Close the valve once water flows consistently.
• Pressure Gauge Reading: The integrated pressure gauge indicates the internal pressure of your filter system. The gauge typically has 'START' and 'CLEAN FILTER' indicators. The 'START' pressure is the normal operating pressure when the filter is clean. As the filter collects debris, the pressure will rise. When the pressure reaches the 'CLEAN FILTER' indicator, it is time to clean or backwash your filter.

7. Maintenance

Regular maintenance ensures the longevity and proper function of your air relief valve:

• Inspect for Leaks: Periodically check the valve for any signs of water leaks, especially around the base and where the pressure gauge connects. A small drip can indicate a failing O-ring or a loose connection.
• O-Ring Condition: The O-ring at the base of the valve can degrade over time, leading to leaks. If leaks are detected, inspect the O-ring for cracks or wear and replace it if necessary.
• Gauge Clarity: Ensure the pressure gauge face remains clear and readable. If it becomes cloudy or difficult to read, the gauge may need replacement.

8. Troubleshooting

If you encounter issues with your air relief valve, consider the following:

• Valve Leaking: If the valve is leaking from its base or around the pressure gauge, the most common causes are a worn O-ring or insufficient Teflon tape on the gauge threads. Replace the O-ring or reapply Teflon tape as needed. If the plastic body is cracked, the entire assembly must be replaced.
• Inaccurate Pressure Reading: If the pressure gauge appears stuck or provides inconsistent readings, it may be faulty and require replacement.
• Air in System: If air continues to enter the system after properly purging, check all connections for leaks, including the pump lid, skimmer basket, and plumbing.
