The Infinity 4000™ Hydraulic System has all the same components of our electric unit, with the addition of the Hydraulic and Pin Hole Motors. The Pin Hole motor has no electrical components, attaches and runs the mechanical portion of the Infinity 4000™ and is controlled by the Hydraulic motor through PCS’ proprietary smart board. The Hydraulic System itself, sits 10 to 50 feet or more away from the swimming pool and is placed near your power source or wherever is convenient to the pool owner.
