Valve Functions and Positions

The Hayward Vari-Flo XL valve provides seven distinct positions‚ each designed for a specific function in the pool filtration process. Understanding these functions is crucial for maintaining a clean and healthy swimming pool.

• Filter⁚ This is the primary position for normal pool operation. Water flows through the filter media‚ removing debris and impurities.
• Backwash⁚ This position reverses the flow of water‚ cleaning the filter media by dislodging trapped debris. It’s essential for maintaining filter efficiency.
• Waste⁚ This position allows for draining the pool water directly to waste‚ useful for removing excess water or debris.
• Rinse⁚ This position helps to settle the filter media after backwashing‚ ensuring even distribution and optimal filtration performance.
• Closed⁚ This position completely shuts off water flow to the filter‚ useful for maintenance or winterizing the pool.
• Winter⁚ This position allows for recirculation of water through the pool without passing through the filter‚ ideal for winterizing the pool.
• Recirculate⁚ This position bypasses the filter‚ allowing for water circulation without filtration‚ useful for quick heating of the pool.

The valve’s handle is clearly marked with corresponding symbols and labels for each position‚ making it easy to identify and select the appropriate function.

Installation and Plumbing

Installing the Hayward Vari-Flo XL valve requires careful attention to detail and proper plumbing connections. Here’s a step-by-step guide to ensure a successful installation⁚

1. Choose the Location⁚ Select a suitable location for the valve near the filter‚ ensuring easy access for operation and maintenance.
