Fitment Notice
Confirm the vessel uses a 12V DC system and that existing sanitation plumbing accepts a 1-1/2" inlet and 1" outlet. The 10-24453-02 is a 24V version and is not electrically interchangeable. BSP-thread variants are available under separate part numbers.
Installation Notes
Mount as close as practical to the holding-tank or bowl discharge outlet, below the outlet where possible. Use marine-grade stranded copper wiring, sealed terminals, and an ignition-protected 20A fuse near the power source. Support hoses so their weight is not carried by the pump. Use sanitation-rated hose and corrosion-resistant clamps. Only unbleached lavatory paper should enter the system — wipes, paper towels, and foreign materials can jam the cutter.
