Operating Instructions
This section covers the essential operating instructions for your Hayward Vari-Flo valve. Learn how to effectively use each valve position to maintain optimal pool health and water clarity effortlessly.
Valve Positions and Their Functions: Filter, Backwash, Rinse, Waste, Recirculate, Winter
Understanding the valve positions is critical for effective pool maintenance. Filter is for normal operation, circulating water for cleaning. Backwash reverses flow to clean the filter. Rinse settles the sand bed after backwashing, preventing debris from entering the pool. Waste bypasses the filter, good for draining the pool or removing heavy debris.
The Recirculate option circulates water without filtering. Winter is used for winterizing, relieving pressure during cold months. Each function plays a vital role in keeping your pool clean, safe, and ready for enjoyment. Using these settings correctly maximizes your Hayward Vari-Flo valve’s potential.
Switching Between Valve Positions
To switch valve positions safely, always turn off the pump first. This prevents damage to the valve and ensures proper function. Depress the handle on the Vari-Flo valve and rotate it to the desired position, ensuring it clicks into place. Never force the handle, as this can damage the internal components.
After selecting the new position, turn the pump back on. Observe the water flow to confirm the correct setting. Regularly switching positions, such as during backwashing, helps maintain optimal water quality. Following these steps ensures your Hayward Vari-Flo valve operates efficiently and extends its lifespan.
Maintenance and Servicing
Regular maintenance is crucial for your Hayward Vari-Flo valve. Servicing ensures optimal performance and longevity. This section covers draining, troubleshooting, and best practices to keep your valve functioning smoothly over time.
Draining Water from the Valve
To drain water from your Vari-Flo valve, first, ensure the system and pump controls are in the off position. Next, depress and rotate the valve handle, positioning the pointer between any detente positions to allow water to escape. Another method is to place the handle pointer on a raised portion of the index hubs at any winter position. This action facilitates drainage, preparing the valve for servicing or winterization. Remember to always depress the handle before turning it to prevent damage to the valve seal. Following these steps ensures safe and effective water drainage from your Vari-Flo valve.
Troubleshooting Common Issues
Encountering issues with your Hayward Vari-Flo valve? A common problem is leaks, often caused by worn O-rings, which can be easily replaced. Difficulty turning the handle may indicate debris obstruction; cleaning the valve interior might resolve this. Reduced water flow could be due to a clogged filter or improper valve positioning. Always ensure the valve is correctly aligned with the desired function. If backwashing is ineffective, check for obstructions in the backwash line. For persistent problems, refer to the parts diagram to identify and potentially replace faulty components. Consulting a professional is advisable for complex issues or if you’re unsure of the repair process.
Safety Precautions
Prioritize safety when operating and maintaining your Hayward Vari-Flo valve. Always turn off the pump before changing valve positions. Follow electrical safety guidelines and prevent violent separation by adhering to instructions.
Preventing Violent Separation
To prevent violent separation of the Hayward Vari-Flo valve components, it is crucial to adhere strictly to the manufacturer’s safety and operating instructions. Failure to do so can result in a hazardous situation, potentially causing serious injury or even death. Always ensure that the system pressure is relieved before performing any maintenance or adjustments on the valve.
Never attempt to disassemble or modify the valve while the system is pressurized. Inspect the valve regularly for any signs of wear or damage, such as cracks or leaks. If any issues are detected, address them promptly by repairing or replacing the affected parts. Following these precautions will significantly reduce the risk of violent separation and ensure the safe operation of your pool system;
Electrical Safety
When dealing with the Hayward Vari-Flo valve, always prioritize electrical safety to prevent shock hazards and ensure proper operation. Before performing any maintenance or installation tasks, disconnect the power supply to the pool pump and filter system. Verify that all electrical connections are properly grounded to protect against electrical faults.
Never work on electrical components with wet hands or in damp conditions. Inspect all wiring regularly for signs of damage, such as frayed insulation or loose connections. Consult a qualified electrician for any electrical repairs or installations to ensure compliance with local codes and safety standards. Regularly check and maintain grounding connections to minimize the risk of electrical shock. By following these electrical safety guidelines, you can protect yourself and others from potential hazards associated with the Hayward Vari-Flo valve.
Installation Guide
Proper installation of the Hayward Vari-Flo valve is crucial for optimal pool system performance. Follow these step-by-step instructions for secure and efficient setup, ensuring correct water flow and preventing leaks.
Connecting the Valve to the Filter System
Connecting your Hayward Vari-Flo valve correctly to the filter system is essential for efficient pool operation. First, ensure all system and pump controls are in the off position. Before beginning, verify that you have the correct fittings and adapters for your specific plumbing. Wrap the threads of the pipes with Teflon tape to ensure a watertight seal. Align the valve ports with the corresponding pipes from the pump, filter, and pool. Securely tighten all connections, but avoid over-tightening, which can damage the valve or fittings. After connecting, double-check all connections for proper alignment and tightness before proceeding to the next step. Remember, a secure and leak-free connection is vital for optimal filtration and water circulation.
Setting System Valves for Proper Water Return
Achieving optimal water circulation requires correctly setting your system valves for proper water return after connecting the Hayward Vari-Flo. Before starting the pump, ensure all system valves are positioned to allow water to flow freely back to the pool. Open the return valves completely to maximize water flow. Check the skimmer and main drain lines to ensure they are properly balanced for optimal suction. Adjust the valves as needed to achieve the desired water circulation pattern. Make sure that the manual air relief valve is open. Monitor the water flow and adjust valve positions as necessary to maintain efficient filtration and water clarity. Proper valve settings are critical for a well-maintained pool.

Draining and Protecting the Valve from Freezing
To properly winterize your Hayward Vari-Flo valve and protect it from potential freeze damage, begin by turning off the pool pump and any associated equipment. Next, depress the valve handle and rotate it to a position between any of the detente positions. This allows water to drain from the valve body. Ensure that all water is completely drained to prevent ice formation, which can cause cracks and other structural damage.
Additionally, consider removing the valve lid assembly to visually inspect for any remaining water. Apply a pool-grade antifreeze to the valve’s internal components for added protection. Finally, store any removed parts in a safe, dry place until the pool is reopened in the spring.
Manual Air Relief Valve
The manual air relief valve is essential for releasing trapped air from the filter system. This ensures optimal filtration and prevents damage to your equipment. Refer to the following for instructions.
Operating the Manual Air Relief Valve
The manual air relief valve is a critical component for maintaining optimal performance of your Hayward Vari-Flo system. Its primary function is to release trapped air within the filter, which can impede water flow and reduce filtration efficiency. To operate, first, ensure the pump is running. Locate the air relief valve, typically found on top of the filter. Carefully open the valve by turning it counterclockwise. Allow the air to escape until a steady stream of water emerges, indicating that all trapped air has been purged. Once the water flow is consistent, close the valve securely by turning it clockwise. This process should be performed regularly, especially after backwashing or any maintenance that introduces air into the system. Proper operation of the manual air relief valve ensures efficient filtration and prolongs the lifespan of your equipment.
