High Flow Manual Air Relief Valve: Operation and Replacement
The High Flow Manual Air Relief Valve is a vital component of the Pentair FNS Plus 36 pool filter system. This valve is responsible for releasing trapped air from the filter tank, which can occur during normal operation or after maintenance activities. Understanding the operation and knowing how to replace this valve is important for maintaining optimal performance and ensuring the longevity of the filter system.
To operate the High Flow Manual Air Relief Valve, simply turn the knob counterclockwise. This action will release the built-up air from the filter tank, allowing water to flow freely. It is important to open the valve slowly to prevent any sudden release of pressure. Once all the air is expelled, the valve can be closed by turning the knob clockwise.
If the High Flow Manual Air Relief Valve becomes damaged or faulty, it will need to be replaced. To replace the valve, first, ensure the filter system is turned off and the pressure in the tank is relieved. Then, unscrew the existing valve from the filter tank by turning it counterclockwise. Once removed, clean the valve seat and apply a thin layer of lubricant before screwing in the new valve clockwise.
It is recommended to inspect and replace the High Flow Manual Air Relief Valve annually or if any signs of damage or wear are present. Regular maintenance and timely replacement of this valve will help prevent water leaks, maintain optimal flow rates, and prolong the lifespan of the Pentair FNS Plus 36 pool filter system.
