Fig. 9 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.
