This section outlines the steps for replacing the air bleed assembly in your Sta-Rite System 2 PLM Series sand filter.
- Prepare the Filter System: Turn off the pool pump and disconnect its power supply. Close any valves leading to and from the filter to isolate it.
- Relieve System Pressure: Open the air relief valve on top of the filter tank to release any trapped air and pressure. Ensure the pressure gauge reads zero before proceeding.
- Drain the Filter: Open the drain plug at the bottom of the filter tank to allow water to drain completely.
- Access the Old Assembly: Depending on your specific PLM model (PLM100 or PLM150), you may need to remove the filter tank lid or access panel to reach the existing air bleed assembly. Refer to your main filter manual for specific access procedures.
- Yọ Apejọ Atijọ kuro: Carefully detach the old air bleed assembly. It is typically secured by a fitting or clips. Note its orientation for correct installation of the new part.
- Fi sori ẹrọ Apejọ Tuntun: Insert the new Pentair 24800-0121 Air Bleed Assembly into its designated position. Ensure it is securely fastened and properly oriented.
- Reassemble the Filter: Close the filter tank lid or access panel, ensuring all seals and O-rings are correctly seated and lubricated. Close the filter drain plug.
- Restore System Pressure: Open the valves to and from the filter. With the air relief valve still open, turn on the pool pump. Allow water to fill the filter tank and air to escape through the air relief valve.
- Close Air Relief Valve: Once a steady stream of water emerges from the air relief valve, close it. Check for any leaks around the filter system.
Video 1: This video demonstrates the replacement process for a similar air bleed kit (WC8-126Z) compatible with Pentair Sta-Rite filters. While not identical to the 24800-0121, it provides a visual guide to the general steps involved in replacing an air bleed assembly in a pool filter system.
5. Isẹ
The air bleed assembly functions automatically to release trapped air from the filter tank during operation. This ensures proper water flow and filtration efficiency. After installation, monitor your filter's pressure gauge. If pressure builds up rapidly or water flow is significantly reduced, ensure the air relief valve is functioning correctly and that no air is trapped in the system.
6. Itọju
Regular maintenance of your air bleed assembly helps prolong its lifespan and ensures optimal filter performance.
- Ayewo: Periodically inspect the air bleed assembly for signs of wear, cracks, or damage. Check the mesh screen for any debris accumulation.
- Ninu: If the mesh screen appears clogged, carefully remove the assembly (following the installation steps in reverse) and rinse it thoroughly with clean water. Do not use harsh chemicals or abrasive tools.
- Rọpo: Replace the air bleed assembly if it shows significant wear, damage, or if you experience persistent air-related issues with your filter system that cannot be resolved by cleaning.
