Tips for installation and care

• Ensure the opening matches the 3-3/4" diameter specification for a flush, secure fit with the 30147 cover.
• Clean the wall surface and inspect the surrounding area for debris before installing to prevent leaks and ensure a tight seal.
• Regularly inspect the suction cover for cracks or warping and clean any buildup to maintain steady flow.
• Match system flow with the 128 gpm rating to maintain balanced circulation and prevent undue strain on pumps and valves.
