SERVICING INSTRUCTIONS (continued) 

TEMPERATURE ADJUSTMENT 

 
Disconnect brewer from electric power. Remove top panel.      
Remove button plug from front 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 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 plug.   

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.
