SERVICING INSTRUCTIONS (continued)
IMPORTANT:  Water pressure 
must be between 20 p.s.i and 
90 p.s.i. flowing pressure. 
If water pressure exceeds this 
value, or if water pressure 
varies greatly, a pressure 
regulator must be installed in 
the water supply line. 
IMPORTANT: Before setting 
assembly into tank, make sure 
tank lid gasket is properly 
seated on flange of lid. 
DO NOT OVER-TIGHTEN. 
 
 
 
 
 
IMPORTANT: When replacing 
temperature probe, be sure a 
new seal washer is in place 
around the probe. Tighten jamb 
lock nut only enough to ensure 
no water leakage. Excessive 
tightening is not necessary. 
 
IMPORTANT: When replacing 
heating element, also replace 
seal gaskets. 
 
BREW TIME ADJUSTMENT
 
The amount of water dispensed automatically during a brew cycle 
is controlled by the SOLENOID TIME dial of the controller. 
 
Place empty decanter under brew chamber. Press BREW 
button. Brewer should dispense one full decanter of water. To 
adjust amount: 
 
Remove brew chamber and button plug. On the controller, adjust 
SOLENOID TIME dial (BREW TIME); clockwise increases time. 
Run several cycles to check amount of water delivered. 
 
DRIPOUT TIME ADJUSTMENT 
 
Water delivered to the brew chamber will take a while to drip 
through as coffee. The time between the end of a brew and 
when a new brew can be initiated is controlled by the BREW 
SIGNAL TIMER. Adjust the BREW SIGNAL TIMER dial on the 
controller to account for the dripout time. Replace button plug.
