SERVICING INSTRUCTIONS
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 the READY TO BREW light first glows, read the temperature displayed on thermometer.
Adjust thermostat by turning shaft; clockwise increases temperature. 1/8 turn = approximately 10ºF, or 5.6ºC.
Refer to Table 1 below for proper brewing temperature based on altitude.
Upon completion, remove thermometer and reinstall the vent line and top panel.
CAUTION
Electric Shock
Hazard
These procedures involve exposed electrical circuits. These procedures are to be performed by qualified technical personnel only.
NOTE: Optimum brewing temperature is 195ºF to 205ºF (90ºC to 96ºC).
Thermostat should be adjusted to a maximum temperature of 200ºF (95ºC).
IMPORTANT:
A mechanical thermostatwill maintain temperature within ±5ºF.
To prevent boiling water in the brewer, controller should be adjusted to a maximum temperature equal to the local boiling temperature minus 5ºF, or 200ºF (94ºC), whichever is
