GLOSSARY

AD CARD: An assembly consisting of computer chips and an instruction label. Used for loading advertising messages into the brewer.

AUTO PULSE BREW SETUP: The setting of a pulse brew routine by entering in the total desired brew time. The brewer will then calculate and perform a pulse brew routine using a predetermined formula.

BREW LOCKOUT: The inability to initiate a brew if the water temperature is less than the ready temperature programmed into the brewer.

CHIP: A computer chip containing either recipes for specific coffee flavors or advertising messages that are read by the sensing coil on the brewer. One chip is embedded in each Smart Funnel handle to carry the coffee flavor name and batch size ground from the grinder to the brewer.

DILUTION: Water added to tea concentrate.

DILUTION DELAY: The length of time from when the brew is initiated until the dilution water starts.

DRIP TIME: The length of time from when the water spray over the grounds ends to the time when no water or product drips from the funnel tip.

ENERGY SAVINGS MODE: If enabled, the brewer will either shut down or reduce the tank holding temperature to 140°F (60°C) after the set idle time.

FACTORY DEFAULTS: The factory preset brew settings that were installed into the brewer’s memory.

FIRST ON-TIME: During a pulse brew, this is the time set for the initial flow of water over the grounds or tea leaves.

FRESHNESS TIMER: If enabled, the brewer will display an alert if a new tea or coffee batch has not been brewed before the set time has expired.

FUNNEL SENSING COIL: A sensor at the front of the brewer that reads what name and batch size of coffee was ground into the funnel and allows for the brewer to automatically set itself to what is read from the funnel handle. Also used to read in recipe and ad card information.

IDLE TIME (ENERGY SAVINGS MODE): If ENERGY SAVINGS Mode is enabled, the length of time the brewer is inactive before the machine turns off or holds at 140°F (60°C).

LAST ON-TIME: During a pulse brew, this is the time set for the second on-time and each alternative on-time for the remainder of the brew.

MAIN SCREEN: The term used to describe the screen that is displayed when the brewer is not in use. This screen is also displayed after exiting the programming mode.

MANUAL PULSE BREW SETUP: The setting of a pulse brew routine by manually entering in the 1st on time, off time and last on time.

MASTER TEMP: The temperature at which the tank will heat to and hold. If the brewer is in Master Temp mode, all initiated brews will be at this temperature.

OFF-TIME: During a pulse brew or preinfusion, this is the time set for the length of time that the water is not spraying over the grounds.

PREINFUSION: The process of beginning a brewing cycle with an initial spray of water onto the grounds followed by a pause in the spray. After the programmed pause, the spray continues without interruption until the end of the brewing cycle.

PULSE BREW: The process that allows the brew water to start, and then stop, repeatedly over the grounds or tea leaves in order to derive the best flavor from the coffee or tea. Pulse brew is also used in some instances to prevent a funnel overflow.
