Bottled/purified water is recommended, as tap water is more likely to cause calcium and mineral buildup. If tap water is used, it must be free of odors that might alter the taste of drinks. Refer to the System Manual for info on water hardness and the impact and frequency of descaling. Refrigerated water also should not be used, as this might impact the temperature of the beverage.
Please always use fresh water and replace water if the system has not been used for an extended period of time.
