Solo-Float is a direct acting, in-line control system for automatically controlling a 1/2 HP and smaller pump motors. The unit has a piggyback plug attached to the cord, allowing the user to plug the pump plug directly into it, and then plug the entire unit into a standard grounded outlet. The Solo-Float is furnished with an adjustable strap for mounting to the pump discharge pipe. Standard units are pre-set at the factory for a nine inch pump down range, but Solo-Floats can easily be adjusted to various pump down cycles by shortening or lengthening the cord length at the pivot point. The Solo-Float is also omni-directional; the pumping differential is maintained in any horizontal plane.
