Brew water temperature is factory set at 200° F (93.3° C)
Areas of high altitude will require lowering this tempera-
ture to prevent boiling. This chart should be used as a
guide when readjusting the brew water temperature.

THERMOSTAT
In most locations the thermostat should be turned to the full clockwise postion (200° F) for optimum brewing
temperature. In areas of high altitude you may have to turn it down (counterclockwise) to prevent boiling.

the switch is pressed, two seconds are added to the brew time period. Allow the brew cycle to finish in order to
verify that the desired volume has been achieved.
To decrease a batch size, Press and release the START or BREW switch once for every two-second interval
to be removed from the total brew time period; then immediately press and hold down the START or BREW
switch until three clicks are heard. Release the switch. (Failure to release the switch within two seconds after the
third click causes the volume setting to be aborted and previous volume setting will remain in memory). Allow
the brew cycle to finish in order to verify that the desired volume has been achieved.
2. Setting batch sizes. To set a batch volume, first check that the SET/LOCK switch is in the “SET” position on
the circuit board. Press and hold the START or BREW switch until three distinct clicks are heard (this will take
approximately ten seconds), and then release the switch. (Failure to release the switch within two seconds after
the third click causes the volume setting to be aborted and previous volume setting will remain in memory). View
the level of the liquid being dispensed. When the desired level is reached, turn the ON/OFF switch to “OFF”. The
brewer remembers this volume and will continue to brew batches of this size until the volume setting procedure
is repeated. Empty server(s), turn selector switch to positions that have yet to be set, and repeat batch setting
procedure until all batch sizes are set.
NOTE: When brewing coffee, batch volumes will decrease due to absorption by the coffee grounds.
3. Setting programming disable feature. If it becomes necessary to prevent anyone from changing brew times
once programmed, you can set the SET/LOCK switch to the “LOCK” position. This will prevent any programming
to be done.
NOTE: If the clicks can not be heard, lightly grip the incoming water line to feel when the valve cycles on
and off.
