The AquaStar PF1025 Relief Valve Assembly is designed to safeguard AquaStar Pipeline Filter models PLF27000 and PLF35000 by regulating system pressure and preventing overpressure damage. Crafted from durable materials with precision engineering, this relief valve delivers consistent performance to maintain system safety and efficiency. Its robust construction ensures long-term durability, making it a critical addition for anyone maintaining or upgrading their filtration system. The PF1025 helps prevent costly issues by keeping pressure within safe operating limits, promoting reliable and safe pool operation.

Note: Do not aim air relief valve at electric equipment or pump controls

• Essential Pressure Regulation Component: Controls internal pressure to prevent overpressure conditions and associated system damage

• Supports Filter System Safety: Helps maintain stable operating pressures, protecting critical components and ensuring reliability

• Durable and Precision-Engineered: Built for long-term use in harsh pool environments with strong resistance to wear

• Vital for System Longevity: Reduces maintenance costs by helping filtration systems operate within recommended pressure ranges

• Reliable Addition for Maintenance Needs: Critical for those seeking to optimize and protect AquaStar PLF27000 and PLF35000 filters

1. Reinstall the filter Cartridge with the “THIS SIDE UP” showing as it is
placed onto the Filter Core Assembly.
2. Lower the Cartridge and Core Assembly into the filter Housing with
the Automatic Air Release screen located on the Outlet side of the
filter Housing. Try to rotate it. If it turns, keep turning until it drops
into place.
3. Install the Lid Assembly by following the instructions above. Make
sure the Locking Ring is fully closed and locked. Check by attempting
to turn the Locking Ring using the SMALL handles in a counterclockwise direction. The Locking Ring should NOT turn.
4. Reinstall the Drain plug, after making sure the O-ring is clean,
lubricated with silicon-based grease (provided) and in place. (or close
the Drain valve if installed).

5. OPEN THE MANUAL AIR RELIEF VALVE ON TOP OF THE FILTER.
6. Open all isolation valves.
7. Stand away from the filter and then turn on the pump, being sure to
follow the pump manufacturer’s priming and start-up instructions. If
the pump is working and isolations are in the correct position, air will
begin existing the Manual Air Relief Valve on the top of the filter.
8. When a steady stream of water comes out of the Manual Air Relief
Valve, close the valve.
9. Observe the operating filter for leaks, keeping in mind that water from the Manual Air Relief Valve may drip down
the side of filter after passing between the filter Housing and the Locking Ring
