The MEGA-PURE Automatic Collection System is designed to collect water from the MEGA-PURE stills and control their operation and store up to 45 liters of Type II distilled water. All glass design with glass inlet and outlet tubing. The ACS is preset to shut off the power to the heaters and the water supply to the MEGA-PURE still after the bottle has collected approximately 45 liters. When the purified water supply has been depleted to approximately 38 liters, the system will automatically restart the water still and refill the collection system. When setting up a MEGA-PURE still with the ACS on a bench, a 6-12" stand (depending on still model) is required. (This will ensure proper gravity feed of distilled water.) Wall or bench mounted.
