Placing the "ON/OFF" switch in the "ON" upper position supplies power to the brew station warmer, enables the brew circuit, and energizes the tank refill circuit. Placing the switch in the "OFF" lower position stops tank refilling, brewing and deenergizes the brew station warmer. Stopping a brew cycle after it has been started will not stop the flow of water into the decanter until the funnel is empty.

NOTE Ð Hot water will be available at the faucet in a limited amount when the switch is in the "OFF" position because the tank will not refill.

BREW SWITCH

Momentarily pressing and releasing the switch starts a brew cycle when the "ON/OFF" switch is in the "ON" upper position.

NOTE Ð The "ON/OFF" switch must be in the "ON" upper position to initiate and complete a brew cycle.

ADDITIONAL WARMER SWITCHES

Placing any additional warmer switch in the "ON" upper position supplies power to the associated warmer.

READY INDICATOR

This indicator glows when the preselected brew water temperature has been achieved.
