Unplug power cord or turn circuit breaker OFF. Remove top
panel.
Pull vent tube out of tank lid and insert a thermometer of known
accuracy in hole. Reconnect brewer to electrical power.
Place empty container under brew chamber. Energize brewer
and allow unit to heat. When the READY TO BREW light first
glows, read the temperature displayed on thermometer.
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

Hazard
These procedures involve
exposed electrical circuits.
These procedures are to be
performed by qualified
technical personnel only.
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 thermostatwill
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 200ºF (94ºC), whichever is
less.
NOTE: 1/8 turn = approximately
10ºF (5.6ºC).
