Pro Tip

Before installing, ensure your equipment pad has sufficient clearance for the 26″ tank diameter and the correct plumbing port size. Load approximately 350 lbs of standard #20 silica sand, and be sure your pump/plumbing system does not exceed the ~70 GPM rating for optimum filter life and performance.

Installation Tips

High‐level safety/compatibility notes only: Shut off pump power and relieve system pressure before servicing. Confirm the filter base is level and rated for the sand load (approx 350 lbs) plus tank weight. Use the correct sand media (#20 silica unless an alternate is approved). Verify plumbing size and multiport valve port size (1½″ or 2″ as applicable) and bond/ground per local code. Do not exceed the maximum flow rating (~70 GPM) for this model and follow the manufacturer’s instructions for backwashing and winterizing.
