INITIAL SET-UP (cont.)

29.If not, unplug the brewer and remove the top lid.

30.Adjust the delay knob of the timer on the right side of the hood as required. Replace the top lid and plug in the brewer.

31.Repeat steps 27-30 until the proper dilution timing is achieved.

ADJUSTING BREW VOLUMES

CAUTION - Disconnect the power source from the brewer prior to the removal of any panel for the replacement or adjustment of any component.

NOTE: Prior to setting or modifying batch sizes, check that the brewer is connected to water supply, the tank is properly filled, and a funnel and server are in place.

1.Modifying batch sizes. To modify a batch volume, first check that the SET/LOCK switch is in the "SET" position on the circuit board.

To increase a batch size. Press and hold the START or BREW 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) and press it again one or more times. 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 batch size. Press and release the START or BREW switch once for every two-second interval to be removed from the total brew time period; then immediately press and hold down the START or BREW 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 batch sizes. To set a batch volume, first check that the SET/LOCK switch is in the "SET" position on the circuit board. Press and hold the START or BREW 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" (lower). The brewer remem- bers this volume and will continue to brew batches of this size until the volume setting procedure is repeated.

NOTE: When brewing tea, batch volumes will decrease due to absorption by the tea grounds.

3.Setting programming disable feature. If it becomes necessary to prevent anyone from changing brew times once programmed, you can set the SET/LOCK switch to the "LOCK" position. This will prevent any program- ming to be done until switch is once again placed in the "SET" position.

AUTO SWEETENER SET-UP

CAUTION - The brewer must be disconnected from the power source throughout the Initial Set-Up, except when specified in the instructions.

1.Remove the top lid and both rear panels.

2.Make sure the brewer water supply is off.

3.Connect sweetener hose from the bag in a box delivery system to the rear fitting marked "Sweetener" . IMPORTANT - System delivery pressure must be regulated between 30-40 psi. System also needs to deliver product for at least 4 minutes without shutting off. Some pump systems shut off after a few minutes of continu- ous running.

4.Set the "Delay knob on the dilution timer to the 3 minute setting. (The minimum delay setting)
