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.

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.
