hayward vari-flo xl valve manual

Key Features and Benefits

The Hayward Vari-Flo XL Valve offers reinforced thermoplastic construction for durability and high flow rates. Its lever handle provides easy operation, enabling seven functions: filter, backwash, rinse, waste, recirculate, and winterize. Designed for compatibility with Hayward sand filters, it ensures efficient pool maintenance. The valve’s design allows for maximum flow, making it a professional choice for pool systems, while its simplicity enhances user experience and system performance.

Installation and Setup

Installation of the Hayward Vari-Flo XL Valve requires connecting it to the pump and filter, ensuring proper orientation and alignment for optimal performance and system functionality.

Pre-Installation Requirements

Before installing the Hayward Vari-Flo XL Valve, ensure the system is turned off and depressurized. Verify compatibility with your pool’s pump and filter system. Check for proper pipe sizing and alignment. Install a pressure gauge using the pipe tap boss provided. Ensure all connections are clean and free of debris. Review the manual for specific alignment and orientation guidelines. Use only Hayward genuine replacement parts for compatibility and safety.

Step-by-Step Installation Guide

Mount the Hayward Vari-Flo XL Valve to the filter system, ensuring proper alignment of the inlet and outlet ports. Connect the pump to the valve’s “PUMP” port. Secure all connections tightly to prevent leaks. Align the valve handle with the desired function port. Use the handle to cycle through positions and test proper flow. Ensure the system is depressurized before starting operation. Refer to the manual for precise alignment and tightening torque specifications.

Operating the Hayward Vari-Flo XL Valve

Operate the valve by rotating the lever handle to select modes like filter, backwash, rinse, and winterize. Ensure proper alignment of the handle pointer with desired functions.

Modes of Operation

The Hayward Vari-Flo XL Valve operates in multiple modes, including filter, backwash, rinse, waste, recirculation, and winterize. Each mode is selected by aligning the handle pointer with the corresponding index hub. Filter mode allows normal pool operation, while backwash cleans the filter. Rinse ensures clean water flows back to the pool after backwashing. Waste mode diverts water to drainage, and recirculation bypasses the filter. Winterize prepares the system for cold weather by draining water. Always refer to the manual for diagrams and detailed instructions.

Using the Lever Handle for Function Selection

The lever handle on the Hayward Vari-Flo XL Valve is designed for easy and precise function selection. To change modes, depress the handle and rotate it to align with the desired position on the index hub. Each position corresponds to a specific operation, such as filter, backwash, or winterize. Ensure the handle is securely aligned to avoid improper function. Always refer to the manual for correct positioning and operation.

Maintenance and Servicing

Regular maintenance ensures optimal performance. Clean and inspect the valve seat gasket, and replace worn parts with genuine Hayward components. Follow manual guidelines for servicing.

Cleaning and Inspecting the Valve

Regular cleaning and inspection of the Hayward Vari-Flo XL Valve are essential for optimal performance. Turn off the pump and relieve pressure before servicing. Inspect the valve seat gasket and key for wear or debris. Clean any dirt or mineral buildup using a soft brush or cloth. Lubricate moving parts if necessary. Replace damaged components with genuine Hayward parts to ensure proper function and longevity of the valve.

Servicing the Valve Seat Gasket and Key

To service the valve seat gasket and key, turn off the pump and relieve pressure. Disassemble the valve by removing the handle and key assembly. Inspect the seat gasket for wear or damage. Replace it with a genuine Hayward part if necessary. Reassemble the valve, ensuring all components are securely tightened. Proper servicing ensures leak-free operation and maintains the valve’s performance over time. Always follow the manufacturer’s guidelines for replacement parts and procedures.

Troubleshooting Common Issues

The Hayward Vari-Flo XL Valve is built for durability, but issues like leaks or valve malfunctions can occur. Always check for worn gaskets and ensure proper handle alignment.

Identifying and Resolving Common Problems

Common issues with the Hayward Vari-Flo XL Valve include valve malfunctions, gasket wear, and handle misalignment. Inspect for leaks, clean debris, and ensure proper handle positioning. If problems persist, consult the manual or contact a professional for assistance. Always follow safety guidelines when servicing the valve to avoid further damage or injury.

Winterization and Drainage

Draining water from the Vari-Flo XL Valve involves depressing and rotating the handle to the winter position, ensuring no water remains in the valve or pump system.

Draining Water from the Valve

To drain water from the Hayward Vari-Flo XL Valve, depress and rotate the valve handle until the handle pointer aligns with a winter position on the index hub. This action allows water to drain completely from the valve, preventing damage during freezing temperatures. Ensure the pump system is also drained as per manufacturer instructions for proper winterization.
