Thermostat Adjustment

NOTE: The thermostat range is approximately 160°F to 200°F. The tank temperature is factory set at 180°F, making the beverage temperature slightly lower than 180°F.

1.Unplug machine.

2.Remove the drip tray.

3.Remove the upper splash panel on the front of the machine by removing the four Phillips head screws.

4.Locate the thermostat adjustment dial on the control board(s).

5.To adjust the temperature of the water being dispensed, turn the adjustment dial on the large* control board. (Turn clockwise to increase the water temperature or counterclockwise to decrease the water temperature)

NOTE: It will take time for the water tank temperature to reach its adjusted temperature setpoint.

￿CAUTION: Do not force the adjustment dial beyond its 270° of rotation or damage to the control board may occur.

*NOTE: PIC 4, 5, and 6 have a second controller. The temperature dial on the right hand board is not active on this board.
