Resumen del manual
2. Remove circuit board and spacers (as required). 3. Remove all wires from the timer. 4. Attach all wires to the replacement timer board prior to installation to the component mounting bracket. Refer to FIG. 7 when reconnecting the wires. 5. Install new circuit board with spacers (as required) to the component mounting bracket. 6. Adjust the timer as described below. Timer Setting: NOTE: Prior to setting or modifying volumes, check that the brewer is connected to water supply, the tank is properly filled, and a funnel and server are in place. NOTE: All volume settings must be done with the sprayhead installed. 10145 072600 Page 18 SERVICE (cont.) DIGITAL BREW TIMER (Late Models)(cont.) 1. Modifying brew volumes. To modify a brew volume, first check that the SET/LOCK switch is in the “SET” position on the circuit board. To increase a brew volume, place the ON/OFF switch in the “ON” position, press and hold the START switch until three clicks are heard. Release the switch and press it again one or more times. (Failure to release the switch within two seconds after the third click causes the volume setting to be aborted and previous volume setting will remain in memory.) Each time the switch is pressed, two seconds are added to the brew time period. Allow the brew cycle to finish in order to verify that the desired volume has been achieved. To decrease a brew volume, place the ON/OFF switch in the “ON” position, press and release the START switch once for every two-second interval to be removed from the total brew time period; then immediately press and hold down the START switch until three clicks are heard. Release the switch. (Failure to release the switch within two seconds after the third click causes the volume setting to be aborted and previous volume setting will remain in memory). Allow the brew cycle to finish in order to verify that the desired volume has been achieved. 2. Setting brew volumes. To set a brew volume, first check that the SET/LOCK switch is in the “SET” position on the circuit board. Place the ON/OFF switch in the “ON” position, press and hold the START switch until three distinct clicks are heard and then release the switch. (Failure to release the switch within two seconds after the third click causes the volume setting to be aborted and previous volume setting will remain in memory.) View the level of the liquid being dispensed. When the desired level is reached, turn the ON/OFF switch to “OFF”. NOTE: Several ounces of water will continue to syphon from the tank after turning the switch “OFF”. The brewer remembers this volume and will continue to brew batches of this size until the volume setting procedure is repeated. NOTE: When brewing coffee, volume will decrease due to absorption by the coffee grounds. 3. Setting programming disable feature. If it becomes necessary to prevent anyone from changing brew time once programmed, you can set the SET/ LOCK switch to the “LOCK” position. This will prevent any further programming until switch is once again put into the “SET” position. NOTE -Brewers with half-batch option will have to be set for both full and half-batch settings.

CONTROL THERMOSTAT FIG. 8 CONTROL THERMOSTAT P2207.40 Location: The control thermostat is located inside hood on the right side just behind the dilution timer. Test Procedures: 1. Disconnect the brewer from the power source. 2. Locate the blue/black wire on the control thermostat. 3. With a voltmeter, check the voltage across the blue/ black wire on the control thermostat and the white wire on the tank heater for 100 volt and 120 volt two wire models or red wire on the tank heater for 240 volt two wire models. Connect the brewer to the power source. The indication must be: a) 120 volts ac for two wire 120 volt models. b) 240 volts ac for two wire 240 volt models. c) 100 volts ac for two wire 100 volt models. 4. Disconnect the brewer from the power source. If voltage is present as described, proceed to #5. If voltage is not present as described, refer to the Wiring Diagramsand check the brewer wiring harness. 5. Locate the black wire on the control thermostat. 6. Gently remove the capillary bulb and grommet from the tank. 7. With a voltmeter, check the voltage across the black wire of the control thermostat and the white wire on the tank heater for 100 volt and 120 volt two wire models or red wire on the tank heater for 240 volt two wire models when the control thermostat is turned fully clockwise. Connect the brewer to the power source. The indi...
