ELECTRICAL
CAUTION- The brewer must be disconnected from the power source until specified. Improper electrical installation
will damage electronic components.
1. Using a voltmeter, check the voltage and color coding of each conductor at the electrical source.
2. When Instructed to proceed, connect the brewer to the power source.
CAUTION- The brewer must be properly grounded. A plumbing line will not provide an adequate ground.
INITIAL FILL AND HEAT
CAUTION- The brewer must be disconnected from the power source until specified. Improper electrical installation
will damage electronic components. Plumbing must be connected to the brewer before proceeding.
1. Make sure the brewer ON/OFF toggle switch is in the off position. The toggle switch is located on the upper
left side of the front panel, just above the pressure gauge
2. Connect brewer to the power source.
3. Place the brewer ON/OFF switch in the “ON” position. The tank will automatically fill. When full the heater
will begin heating the water in the tank.
NOTE: The tank heater switch is shipped in the “ON” position, and during normal operation should stay
there. This switch is located on the DBC control board behind the right hand side panel. If service is required
this switch may be turned off to disable the heating circuit.
During initial fill, using a bottled water source, a fault may occur. The controller will detect that the
tank is not filling fast enough.
If this occurs power down the unit. Reinitiate start-up procedures and the unit will complete filling.
The unit will begin heating after filling. If necessary, repeat until tank is properly filled.
4. When the steam side of the pressure gauge is in the green area the brewer is ready for selection
of one of the four drinks and the size drink desired..
