4)  Once you are satisfied with the by-pass %, you can begin calibrating the brew volume. Set the volume selector 

switch to “I”. Depress the brew start/stop switch to resume brewing. After the brew cycle has finished check volume 
of water in the container. Adjust the "brew time" with the control board located behind right side access plate. Turn 
the dial clockwise to increase the volume of water and counterclockwise to decrease it. The “II” position on the 
volume selector switch is automatically set to deliver twice the volume as the “I” position. As an alternate method for 
setting brew time: Turn the timer adjustment clockwise to the maximum setting and initiate a brew cycle. When the 
water level in the container is reached, slowly turn the timer adjustment counter clockwise until you hear the water 
valve turn off. The timer is now set to deliver the volume of water. This Auto Cal feature allows you to streamline the 
calibration process. The dial labeled “Visa” on the timer may be set for an additional amount of time to flash the brew 
indicator on the face plate to allow time for the coffee to finish draining from the brew basket after the fill cycle has 
completed.  See Figure below for control board setting information. 

 
5.  Allow 10-15 minutes for the water in the tank to heat to brewing temperature. The heating light will go out when the 

unit is up to temperature. Run one brew cycle to check for the proper temperature setting with an accurate 
thermometer. Take the temperature of this water at a point below the brew basket opening, at the start of the brew 
cycle and when the decanter is half full. Recommended temperature of the water is approximately 195 F.       (Note: 
Brew cycle may be canceled by depressing the brew start/stop switch). The brewer features an electronic 
temperature control circuit and the temperature may be adjusted with the control board located behind the right side 
access plate. See Figure below for control board setting information. 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
6.  In higher altitude locations (5000 feet above sea level) the tank temperature may have to be adjusted lower to 

prevent boiling. Turning adjustment knob in a clockwise direction will increase water temperature. This unit features 
an electronic temperature control. Adjustment is located on the control board behind the right side access plate. 

 
7.  CAUTION: The water faucet will dispense hot water when the handle is pulled.
