The Pentair Top-Load filter has a built-in spring-loaded by-pass which allows 100% filtration of the water on low speed of two speed pumps. During high speed operation, the spring opens, permitting unrestricted flow and maximum hydrotherapy action.
Installation : The filter must be installed on the pressure side of the filtration pump with flow arrow on bottom manifold pointing in direction of water flow.
