The CPSI-370N is a combination appliance by means of which not only water is filtered and cooled, but also ice and carbonated water can be made. The device operates via an automatic carbonator system which allows carbonated water to flow from the output directly into the glass by pushing a button – a special bottle for the carbonation is not necessary. The intuitive operating interface allows a choice between three concentrations of carbonisation, cooled and filtered water or ice.
