4. Wait approximately twenty minutes for the water in the tank to heat to the proper temperature.
5. Place an empty server beneath either brew station and the ON/OFF switch in the upper ("ON") position.
6. Triple-set Timers only: Place the brew station Selector switch in the 1
1
⁄2 gallon position.
7. (A) Initiate a brew cycle; after water has stopped flowing from the funnel, place the ON/OFF switch in the lower
("OFF") position and check the water volume in the server. It should be 192 ounces (5.7 L) for 1 1/2 gallons.
If not, adjust the timer as required. Refer to
Adjusting Brew Volumes
NOTE: Each batch setting must be adjusted individually, if they are not correct. Volumes are as follows:
1 gallon - 128 ounces (3.8L)
.5 gallon - 64 ounces (1.9L)
(B) If necessary adjust the needle valve to achieve desired water volume to be bypassed around the coffee filter
in the funnel.
NOTE: To increase the water bypass turn the needle valve counterclockwise, to decrease the water bypass turn
the needle valve clockwise. An adjustment of the needle valve will require a timer adjustment for volume. To
determine how many turns must be performed to achieve the desired volume, use the chart below.
NOTE: The factory bypass is set at 20%
