These procedures are to be
performed by qualified
technical personnel only.
NOTE:
Optimum brewing temperature
range is 195ºF to 205ºF (90ºC
to 96ºC).

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.
