TEMPERATURE ADJUSTMENT
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 vent hole. Reconnect brewer to electrical power.
Place an empty decanter under brew chamber. Energize brewer
and pour one decanter (64 oz.) of cold water into pour-over
opening. When READY TO BREW light comes on, read
temperature displayed on thermometer.
Adjust thermostat by turning shaft; clockwise increases
temperature. 1/8 turn = approximately 10ºF.
Refer to Table 1 below for proper brewing temperature based on
altitude.
Upon completion, remove thermometer and reinstall vent tube.

Hazard
These procedures involve
exposed electrical circuits.
These procedures are to be
performed by qualified
technical personnel only.
NOTE:
Optimum brewing temperature
range is 195ºF to 205ºF (90ºC
to 96ºC).
IMPORTANT:
A mechanical thermostat will
maintain temperature within
±10ºF. To prevent boiling water
in the brewer, thermostat should
be adjusted to a maximum
temperature equal to the local
boiling temperature minus 10ºF.
