TEMPERATURE ADJUSTMENT
Energize brewer and allow unit to heat. When the READY TO
BREW light first glows, read the temperature.
Thermostat may be adjusted by removing the right button plug.
Carefully check the water temperature at the outlet of the brew
chamber. The temperature at this location is approximately 5º F
less than the actual brew temperature.
Adjust thermostat by turning shaft; clockwise increases
temperature. 1/8 turn = approximately 10ºF, or 5.6ºC.
Refer to Table 1 below for proper brewing temperature based on
altitude.
Upon completion, remove thermometer and reinstall the vent line
and top wrap.

CAUTION:
SHOCK HAZARD
Live electrical circuits are
exposed during this procedure.
Use care to avoid uninsulated
electrical connectors.
NOTE: Optimum brewing
temperature is 195ºF to 205ºF
(90ºC to 96ºC).
Thermostat should be adjusted
to a maximum temperature of
200ºF (95ºC).
IMPORTANT:
A mechanical thermostat will
maintain temperature within
±5ºF.
To prevent boiling water in the
brewer, controller should be
adjusted to a maximum
temperature equal to the local
boiling temperature minus 5ºF,
or 205ºF (97ºC), whichever is
less.
NOTE: 1/8 turn = approximately
10ºF (5.6ºC).
