5. Operating the Filter
Once installed, the Filters Fast FF-1286M filter operates continuously with your pool or spa pump to circulate and clean the water. Ensure your pump runs for an adequate duration each day (typically 8-12 hours for pools, depending on usage and size) to maintain proper filtration and water chemistry.
- Monitor Pressure Gauge: Regularly check the pressure gauge on your filter tank. An increase in pressure (typically 8-10 PSI above the clean operating pressure) indicates that the filter needs cleaning.
- Maintain Water Chemistry: Proper water balance and sanitation are crucial for filter performance and longevity. Follow recommended guidelines for pH, alkalinity, calcium hardness, and sanitizer levels.
