2. Configuración e instalación
Proper installation is crucial for the optimal performance and longevity of your Hayward ProSeries Sand Filter. Please follow these general guidelines. Refer to the detailed diagram and specific instructions provided with your product packaging for precise steps.
- Selección del sitio: Choose a level, firm surface as close to the pool as possible. Ensure adequate drainage and protection from direct sunlight or extreme weather.
- Conjunto de filtro: Carefully unpack all components. Ensure the underdrain laterals are properly seated at the bottom of the filter tank.
- Sand Loading: Place a small amount of water in the tank to cushion the laterals. Carefully add the recommended amount of filter sand (typically 150 lbs for the 18-inch model) into the tank. Ensure the standpipe is centered during this process.
- Multiport Valve Installation: Secure the 7-position VariFlo valve to the top of the filter tank, ensuring a tight seal.
- Conexiones de fontanería: Connect the pool's skimmer/main drain line to the 'PUMP' port on the valve, and the return line to the 'RETURN' port. Connect the waste line to the 'WASTE' port. Ensure all connections are secure and leak-free.
- Conexión de la bomba: Connect your pool pump to the filter system according to the pump manufacturer's instructions.
- Puesta en marcha inicial: Before starting the pump, ensure the filter tank is filled with water. Set the multiport valve to the 'BACKWASH' position and start the pump. Backwash until the water in the sight glass is clear. Then, set the valve to 'RINSE' for 30-60 seconds, followed by 'FILTER'.
3. Instrucciones de funcionamiento
The 7-position VariFlo valve allows for various operational modes. Always turn off the pump before changing valve positions to prevent damage to the system.
- FILTRAR: Normal filtration mode. Water flows through the sand bed, trapping debris, and returns to the pool.
- RESACA: Used for cleaning the filter sand. Water flow is reversed, flushing trapped debris out through the waste port. Perform when pressure gauge reads 8-10 PSI above starting pressure.
- ENJUAGUE: Used after backwashing to flush out any remaining dirty water from the filter and settle the sand bed. Run for 30-60 seconds.
- DESPERDICIAR: Bypasses the filter, sending water directly out the waste port. Useful for vacuuming heavy debris directly to waste or lowering pool water level.
- RECIRCULAR: Evita el filtro y devuelve el agua directamente a la piscina. Útil para la distribución de productos químicos sin filtración.
- CERRADO: Shuts off all flow to the filter and pool. Use only when servicing the pump or filter. Never operate the pump with the valve in the 'CLOSED' position.
- PREPARAR PARA EL INVIERNO: (If applicable) Position for draining the filter for winter storage.
4. Mantenimiento
El mantenimiento regular garantiza la longevidad y la eficiencia de su filtro de arena.
- Lavado a contracorriente: Backwash your filter regularly, typically when the pressure gauge reads 8-10 PSI above its clean operating pressure. This usually occurs every 1-2 weeks, depending on pool usage and debris.
- Reemplazo de arena: Filter sand typically lasts 3-5 years before needing replacement. Over time, sand particles wear down and become less effective at trapping debris.
- preparación para el invierno: In colder climates, the filter must be properly winterized to prevent freeze damage. Drain all water from the filter tank and plumbing lines. Store the multiport valve in the 'WINTERIZE' or 'CLOSED' position with the drain plug removed.
- Inspección: Periodically inspect the filter tank, valve, and plumbing for any signs of cracks, leaks, or wear. Address any issues promptly.
