* SET NEW RECIPE (COFFEE ONLY)

To set a new COFFEE recipe using a Smart Funnel and a G9-2T DBC or MHG Grinder: This function allows the operator to set BREW VOLUMES, BYPASS %, PULSE BREW/PREINFUSION TIMES AND DRIP OUT TIMES for each coffee name

stored in the grinder’s memory.

Certain coffee names are stored in the grinder’s memory. When a particular name of coffee is ground into the Smart Funnel, that name and the batch size selected are transferred from the grinder to the programming CHIP located in the funnel handle. The funnel is then inserted into the brewer’s funnel rails. The SENSING COIL on the brewer reads the information contained in the handle. The name of the coffee ﬂavor will then appear on the display. This allows the operator to set the

BREW VOLUMES, BYPASS % (N/A on ITCB), PULSE BREW/PREINFUSION TIMES AND DRIP OUT TIMES for

that particular coffee name. Each coffee name can be set individually to provide optimum brewing quality.

PROBLEM

Automatic reﬁll will not operate or display shows FILL TIME TOO LONG

PROBABLE CAUSE REMEDY

1. No water

Check plumbing and shut-off valves

2. Reﬁll probe or Sensitivity setting

3. Reﬁll valve

Remove the strainer and check for obstructions. Clear or replace.

Check the sensitivity setting. Refer to the REFILL function on page

40. If the left three digit number is less than the right number, the machine “thinks” it is full and the reﬁll valve should be off. If the left number is larger than the right, then the reﬁll valve will automatically be turned on to ﬁll the tank. The right number is the threshold setting and can be adjusted to compensate for extreme water conditions: very pure, low conductance water requires a higher setting, while high mineral content, high conductance water requires a lower setting. Note that the left number changes from a high value when water is NOT touching the reﬁll probe to a low valve when water IS touching the probe. For best operation, the right number should be set to a value midway between these low and high numbers. Before changing the setting, conﬁrm that the reﬁll probe is free of scale buildup and the connection to it is secure. Test the reﬁll valve. Refer to the test outputs procedures on page 48.
