INTRODUCTION

The brewer incorporates a wireless interface system that allows the DBC Grinder to load certain information into the
"programming tag" located inside the handle of the funnel. This information includes what flavor of coffee is being
ground and what batch size will be brewed (small, medium, or large). Once the correct flavor name and amount of
coffee is ground, the funnel is loaded into the brewer. The information from the funnel handle is then transferred into
the brewer. The brewer then takes this information and dispenses the amount of water preset in the brewer for that
particular flavor of coffee and batch size. The brewer can also be programmed to adjust different functions of the
brewing process, such as brew temperature, brew volumes, bypass percentages, pulse brew, etc. This allows the
operator to program a certain "recipe" for each coffee flavor to be brewed.

3. If a G9-2T DBC or MHG grinder is used with a compatible Smart Funnel, select the desired batch size on the
grinder. Grind the selected amount of fresh coffee into funnel and level grounds by gently shaking. It is not
necessary to select a size on the brewer.

4. Slide the funnel into the funnel rails. The brewer will read the size ground through the chip in the funnel
handle and will automatically select the correct size to brew.

5. Place an empty server under the funnel.

6. The ENABLE BREW switch must be ON. Momentarily press and release the "BREW" switch. If the brewer has
the funnel lock option and if it is activated, once a brew cycle has been started the funnel is locked in place.
There may be certain situations in which the brew cycle will not begin when the brew switch is pressed:

a) BREW TEMPERATURE TOO LOW - wait until heated or cancel BREW LOCKOUT option.
b) FUNNEL NOT IN PLACE (or using a standard brew funnel) - cancel FUNNEL DETECT option.
c) CHECK FUNNEL - remove funnel, empty previously brewed grounds and grind a new batch into funnel.
d) SERVER NOT IN PLACE - place Soft Heat Server, or cancel SERVER DETECT option.

7. If none of the above messages are displayed, the display will read NOW BREWING and the time remaining
in the brew cycle. Arrows will point to the side which is brewing. If both sides are brewing simultaneously,
the arrows will alternate from left to right on the display.

8. Following the BREW will be a countdown of DRIPPING time which shows the time remaining until the funnel
lock will release. Discard the grounds and filter only after visible dripping stops.
