SERVICING INSTRUCTIONS (continued)
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 hole. Reconnect brewer to electrical power.
Place empty container under brew chamber. Energize brewer
and allow unit to heat. When READY indicator lights, read the
temperature displayed on thermometer.
Adjust WATER TEMP shaft on thermostat; clockwise increases
temperature. Refer to Table 1 below for proper brewing
temperature based on altitude.
Fig. 10 Checking and Adjusting Brew Temperature
CAUTION
Electric Shock
Hazard
These procedures involve
exposed electrical circuits.
These procedures are to be
performed by qualified
technical personnel only.
Adjustments to be performed by
qualified technician only.
NOTE:
Optimum coffee brewing
temperature is 195ºF to 205ºF
(90ºC to 96ºC).
Thermostat should be adjusted
to a maximum temperature of
203ºF (95ºC).
NOTE: Water temperature
adjustments may be made by
removing the appropriate button
plug from the side of the brewer,
then turning the thermostat
adjustment shaft. Check water
temperature at the brew head
for coffee, or at the faucet for
hot water. Because of losses in
the connecting piping, the
procedure at left provides a
more accurate gauge of the
actual tank temperature.
IMPORTANT:
A mechanical thermostat will
maintain temperature within
±10ºF (±6ºC).
To prevent boiling water in the
brewer, controller should be
adjusted to a maximum
temperature of 10ºF(6ºC) less
than the local boiling
temperature, or 202ºF (94ºc),
whichever is less.
NOTE:
1/8 turn = approx 10ºF (5.5ºC)
