Explains how to select a pump for a Perflex filter, including pump type, power, and location.
The Hayward Perflex Model EC50 is a high-performance swimming pool filter designed for continuous operation with fresh or salt water. It utilizes diatomite (D.E.) powder to remove dirt efficiently through an exclusive 'BUMP' action that regenerates the filter media without dismantling the unit. The manual covers pump selection, plumbing requirements, and specific installation steps for both above and below-water line configurations.
