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 brew basket, 1/3 of
the way through the brew cycle. The temperature should be 195
°F ± 5°.
If an adjustment is necessary:
• Turn the power switch off.
• Remove the four screws on the upper cover. The upper water tank is attached to the cover.
• Lift the cover and tank just enough to reach the thermostat, which
is located on the right side, under the tank.
• Turn the adjustment stem slightly counter-clockwise to increase
the temperature, and clockwise to decrease the temperature.
• Place the tank and cover in their normal positions and turn the
power switch on.
• If you decreased the temperature setting, place a container
under the brew basket and pour water into the top of the brewer
until the “ready” light goes out
• Wait for the “ready” light to come on, and measure the temperature again.
Repeat until the desired temperature is obtained.
Effective December, 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 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
= 75°F
8 7
= 187°F
0 3
= 203°F
