TEMPERATURE ADJUSTMENT
Disconnect brewer from electric power.
Pull vent tube out of tank lid and insert a thermometer of known
accuracy in hole. Reconnect brewer to electrical power.
Place empty cup on the cup grid. Energize brewer and allow unit
to heat. When READY light glows, read the 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 the vent.
Fig. 7 Checking and Adjusting Brew Temperature
CAUTION:
SHOCK 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
±5ºF. To prevent boiling water
in the brewer, thermostat should
be adjusted to a maximum
temperature equal to the local
boiling temperature minus 5ºF.
