Pentair Rainbow Dynamic Series II & III filters
The Pentair Top-Load filter has a built-in by-pass which works with a spring and allows 100% water filtration on the low speed of two speed pumps. When the pump is running on high speed, the spring opens, permitting unrestricted flow and maximum hydrotherapy action.
The filter must be installed on the pressure side of the filtration pump with the flow arrow on the bottom manifold pointing in the direction of water flow.
