• Release all air in system before testing. Hazardous Pressure! • Tighten Sta-Rite pump trap lids to 30 ft. lbs. (4.1 kg-cm) torque for testing. • Water pressure for test must be less than 25 PSI (172 kPa). Can cause tank •...
Hazardous pressure. Open air release valve to vent all air from system before operating system. NEVER operate filter with air trapped inside. • The Sta-Rite modular DE filter is designed to filter water for swimming pools. On a new pool installation, we recommend: When to Clean the Filter 1.Disassemble the filter after the initial cleanup.
• Support pipe independently to prevent strains on filter. • Fittings restrict flow; for best efficiency use fewest possible fittings. • For ease of maintenance, use Sta-Rite union couplings to connect the piping to the filter inlet and outlet ports.
Latch 7. To prepare precoat slurry, mix diatomaceous earth (DE) and water. Use four pounds of DE for Model PLD70; use six pounds of DE for Model PLD50. DO NOT use more DE than recommended. NOTICE: Using more than the recommended amount of DE will clog the 2149 1195 filter.
Disassembly: 1. Stop the pump. 2. Close isolation valves to prevent flooding. 3. Open air release valve on top of filter tank to release all pressure from inside of tank. NOTICE: Make sure that waste water disposal complies with local codes and ordinances.
MODULE CLEANING PROCEDURE When to Clean the Filter Risk of chemical burns. Do not attempt to acid clean the filter or The filter module should normally be cleaned when the pressure gauge reading module. If the filter requires acid cleaning, have a trained pool professional do increases 10 PSI over the start-up pressure the job.
SYSTEM INSPECTION General: Wash the outside of the filter with a mild detergent and water. Rinse off with a hose. NOTICE: DO NOT use solvents to clean the filter; solvents may damage plas- tic components in the system. NOTICE: Open the air bleed valve and bleed all air from the filter each time the pump is stopped and restarted.
TROUBLESHOOTING GUIDE 1. Short Cycle Time: C. Water is chemically out of balance; consult pool professional. NOTICE: Cycle Time will vary with each installation D. Excessive air in filter; non-precoated areas may and between different areas of the country. The follow- plug.
