Setup and Installation
Proper installation is crucial for the filter's performance and longevity. Follow these steps carefully:
- Site Selection: Choose a level, solid surface for the filter, preferably close to the pool pump and electrical outlet. Ensure adequate clearance for maintenance.
- Plumbing Connections: Connect the filter to your pool's plumbing system using the provided 2-inch by 2 1/2-inch universal unions. Ensure all connections are watertight.
- Backwash Valve Installation: Install a compatible Zodiac backwash valve (sold separately) according to its specific instructions.
- DE Powder Addition: After initial setup and filling the filter with water, add the recommended amount of Diatomaceous Earth (DE) powder through the skimmer while the pump is running. Consult your pool professional for the correct dosage.
- System Check: Once installed, open all necessary valves and prime the pump. Check for any leaks and ensure the pressure gauge reads within the normal operating range.
Operating Instructions
Operating your DEV48 filter is straightforward. Follow these guidelines for optimal filtration:
- Initial Start-up: Ensure the filter is filled with water and the correct amount of DE powder has been added. Turn on the pool pump.
- Pressure Monitoring: Regularly observe the pressure gauge. Note the initial clean pressure reading.
- Cleaning Indicator: The pressure gauge includes a clean or dirty indicator. When the pressure rises 8-10 PSI above the initial clean pressure, or when the indicator shows "dirty," it's time to backwash the filter.
- Continuous Operation: For best results, operate your filter for at least 8-12 hours per day, or as recommended by your pool professional.
