WARMERS
Adjusting the Temperature
Gemini Warmers feature three temperature settings. Warmers are rated at 90W 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 BREW
button is pressed.

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.

will now start a pattern of LONG and SHORT blinks.
READY TO BREW
This pattern identifies the number of brew cycles. SHORT blinks indicate the brew number from one [1] to
nine [9]. LONG blinks separate the 1's, 10's, 1,000's and 10,000's.
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.
