Pro Tip

To maximize performance, ensure your pump and plumbing deliver flow at or below the ~160 GPM guideline rating. Confirm you have at least ~74″ vertical clearance above the unit for cartridge removal and lid access. When your pressure gauge climbs about ~10 psi above its clean-start reading, conduct maintenance—rinse cartridges or backwash as appropriate. Use genuine replacement cartridges and inspect the O-ring, clamp ring, and lid seal with each service cycle.

Installation Tips

High-level safety/compatibility notes only: Disconnect power to the pump and relieve system pressure before installation or servicing. Ensure the filter is mounted on a level, supported pad rated for the full weight of tank + water + cartridges. Confirm plumbing ports (2″ standard) match your system or use adapters as needed. Lubricate the O-ring and ensure the clamp ring or lid fasteners are correctly torqued. Use a compatible multiport or slide valve rated for the system flow (valve sold separately). Confirm the air-relief valve is functioning and the drain port is accessible before restarting the system.
