Operating the Hayward Vari-Flo XL Valve
Understanding the Valve Positions
The Vari-Flo XL features a large handle with clearly marked positions, typically including:
- Filter: Normal operation for filtering pool water.
- Backwash: Reverses flow to clean the filter media.
- Rinse: Flushes debris from the system after backwashing.
- Waste: Bypasses the filter to remove debris directly.
- Recirculate: Circulates water without filtering.
- Closed: Stops water flow through the system.
Switching Between Positions
To change the valve setting:
1. Turn off the pump before adjusting the valve to prevent water pressure stress.
2. Grasp the handle firmly.
3. Rotate the handle smoothly to the desired position, aligning it with the corresponding indicator.
4. Ensure the handle is fully seated in the new position to prevent leaks or partial flow.
5. Turn on the pump and observe the system for proper operation.
Performing Backwashing and Rinsing
Proper backwashing and rinsing are vital for maintaining filter efficiency:
- Backwashing:
- Switch the valve to the Backwash position.
- Turn on the pump and allow water to run until the sight glass (if available) is clear.
- Typically, backwash lasts 2-3 minutes.
- Rinsing:
- Switch the valve to the Rinse position.
- Run the pump for about 30 seconds to settle debris.
- Return to the Filter position for normal operation.
