Adjustments

Thermostat Adjustment:
For equipment manufactured before April 1, 2004
The brewer's water tank temperature is factory set at 205°F (slightly lower for high altitudes, to prevent boiling).
This setting will deliver water at 195°F ± 5° to the coffee grounds.
Measure the temperature by holding a thermometer in the stream of water flowing out of the hot water faucet. The
temperature should be 195°F ± 5°.
If an adjustment is necessary:
•
Remove the upper cover of the unit.
•
The thermostat is located in the upper section of the brewer. Locate the adjustment stem, which
may be taped to the thermostat.
•
Insert the stem into the adjustment hole.
•
Turn the adjustment stem slightly clockwise (as viewed from the stem insertion point) to increase
the temperature, and counter-clockwise to decrease the temperature.
•
If you decreased the temperature setting, run 2 or 3 brew cycles to allow enough cold water into
the brewer to lower the tank temperature.
•
Wait for the "ready" light to come on, and measure the temperature again.
•
Repeat until the desired temperature is obtained.
•
Replace the cover(s).
Effective April 1, 2004:
A new digital thermostat and temperature probe were introduced as a direct replacement for the old style
thermostat and probe.
During normal operation, the digital readout displays the last two digits of the actual water temperature. When the
adjustment tool is turned, the readout begins flashing to indicate the set point, not the actual temperature. After the
tool is released, the readout stops flashing and displays the actual temperature again.
A red LED lights when the power to the thermostat is on. A yellow LED lights when the thermostat is calling for
heat.
To adjust, turn the adjustment tool. If no adjustment tool is present, a small flat-head screwdriver may be used. The
display will flash, indicating that the display is showing the set point, not the actual temperature.
The default temperature scale is Fahrenheit. When set to Fahrenheit, the
display shows only the last 2 digits of the temperature.
The dots below the numbers indicate the temp range.
0 dots – less than 100° F
1 dot – between 100° and 200° F
2 dots – over 200° F
Examples:
7 5
8 7
0 3

= 75°F
= 187°F
= 203°F
