INITIAL SET-UP

CAUTION – The brewer must be disconnected from the power source throughout the initial set-up, except when specified in the instructions.

NOTE: ECA Models Only - This brewer is equipped with a temperature sensor that indicates when to brew and, when selected, locks out the start of a brew cycle until the water has heated to the optimum brewing tempera- ture.
