OPERATION 

IMPORTANT: 

All E-Max™ brewers are 
tested and set at the  factory.  
If programming adjust-
ments are necessary,   
refer to the appropriate 
section of this manual. 
 

 
To over-ride the Brew 
Wait mode

, press and 

hold the BREW key for    
3 seconds when the 
brewer is in Brew Wait 
mode (i.e. when brew light 
is flashing).  The brew will 
proceed immediately    
regardless of water     
temperature.  This feature 
should only be used when 
testing water volume,   
otherwise the brew will 
proceed with the water 
below the precise brew 
temperature.  
 
 

Note:   

the following 

safety features have been 
incorporated to prevent 
multiple unattended 
brews: 

 

The brew key is disabled 
during a brew cycle.  This 
minimizes the possibility 
of double   brewing.  

 

When the “Brew” light is 
on or flashing, repeated 
pressing of the BREW 
switch will be ignored, 
(there will be a beep each 
time it is pressed).  A 
Brew will only be activated 
when the “Brew” light is 
off. 

1.

 

Energizing the Brewer:

 When electricity has been connected to 

 

the unit, there will be a momentary flash of the power light.  Turn        

 the brewer on by pressing the POWER key. The 
brewer will start to fill the tank.  With the proper   
water supply the tank should be filled in about 2½ 
minutes.  Once filled, the heating  element will come 
on until the proper tank  temperature has been 
reached, (which will take about 20 minutes on    
120-Volt models or about 12 minutes on 120/240 
Volt models)

 

2.  Brewing (Precise Temperature for Brewing™ — PTB™):

 In the 

 

regular operating mode, the E-Max™ maintains the tank            

temperature /- 1ºF of the brew temperature. 
Normally this will mean that a brew will be started 
as soon as the BREW key is pressed.  However, 
there may be a slight  delay if the BREW key is 
pressed immediately after a brew has been      
completed (notably on 120 volt models).  If the tank 
temperature is below the brew temperature, the 
brew will be delayed, going into the “

Brew Wai

t” 

mode, with the brew light flashing.  As soon as the 
correct temperature is reached the brew will     

commence with the brew light on continuously during the brew.  When 
the brew begins the main warming station will be turned on             
automatically (if it is not already on). During the brew cycle, if the 
BREW key is pressed, it will be ignored.  Only when the brew is       
complete can another brew be started. 
 

3. Brew 

Cancel:

 To cancel a brew in progress, press the CANCEL 

KEY: two beeps will sound and the “Brew” light  
will go out.  Water flowing to the brew chamber  
will be stopped immediately, but if there is 
already water in the brew chamber, it will take a       
few moments before this drips through as 
coffee. 
 
 

 
 

4.  Normal Operation (Non Brewing):

 When the unit is not brewing, 

 

the E-Max™ maintains the water temperature at the Precise 

 

Temperature for Brewing™ (PTB™).   The heating element will   

 

cycle on and off automatically to maintain this temperature. 

 

5.  After Hours Mode:  

If no brew is detected for a pre-selected length 

 

of time, the brewer will enter the After Hours mode.  Temperature 

 

will be allowed to drop to save energy.  Pressing the BREW KEY 

 

returns the brewer to normal operation.
