PROGRAMMING LOCKOUT SWITCH (mounted on main control board)

This switch can be set to prevent access to the programming levels of the brewer. Once all the cor- rect brew settings are programmed, the operator can set the switch to the "DISABLE" position to prohibit anyone from changing the settings.

BREW LOCKOUT? NO DONE YES

This screen will be shown when the brewer is ready for use. The screen displays the water temperature in the tank. When the water in the tank reaches the correct set temperature, the display will change from HEATING to READY TO BREW.

READY TO BREW WATER TEMP: 205°

The following function screens are in order of appearance. Each screen will have instructions on how to access, and the procedures to program the various functions of the brewer.
