PROGRAMMING
2
IMPORTANT – Before entering the program mode, allow the unit to reach brewing temperature, then press the
BREW button to dispense at least 12 ounces of water to clear any air that may be trapped within the water lines.
NOTE: NOTE: NOTE: NOTE: NOTE: For ALL functions you must first enter the programming mode.
WARNING These steps
involve working with hot
water. Scalding may occur if
care is not taken against spilling.
1. Slide brew cone out to expose bypass outlet. Place one measuring cup under the bypass fitting, and
another measuring cup under the brew cone outlet. Press the LARGE brew button for 15 seconds, then press
the ON/OFF button to stop the brew cycle.
2. Divide the number of ounces collected from the bypass outlet into the total ounces collected from the
sprayhead and bypass. This will determine the percentage of bypass.
3. To increase or decrease the volume of bypass water, turn the adjustment screw on the bypass valve as
indicated. Clockwise for less water; counterclockwise for more water.
4. You must reprogram the brew volume to maintain the proper total amount of coffee brewed into the insulated
server. Reprogramming is required every time you make a bypass adjustment or change to a different
sprayhead.

SLEEP MODE (220V Models Only) – Factory Preset to Disabled
This function conserves energy by automatically reducing tank temperature to 140º F when the unit sits idle for
more than two hours. To recover, simply press any BREW (or Grind button if InterLocked) or ON/OFF button. Once the
water in the tank reaches brewing temperature, the brew cycle will automatically start. Recovery is indicated by a
yellow RECOVERY light on the membrane control panel. Recovering from a SLEEP mode is faster and more efficient
than heating after switching off the power.
To ENABLE Sleep Mode:
UNIT MUST BE ON. Press and HOLD until SLEEP light turns ON; press again.
Sleep Mode is now ENABLED.

WARMERS
Gemini Warmers feature three temperature settings. Warmers are rated at 100W with High (100%); Med (60%);
Low (30%).
Pressing the WARMER button once will place it on HIGH; A second time MED; Third time LOW as indicated by
the warmer lights. A fourth press of the warmer button turns off the warmer.
When the system is turned off at the ON/OFF button, it will remember the last warmer setting. Additionally, if the
warmer is off, the unit is designed to automatically turn the warmer on (MED setting) when the next brew cycle is
started.
