INSTALLATION INSTRUCTIONS
WARNING:
- Read and follow installation instructions before plugging or wiring in machine to electrical circuit.
1) Place a suitable container in place below the brew basket to catch water. Depress the brew start/stop switch and the
tank will begin to fill. The tank lid has a probe in it to signal the control board when the water has reached the
appropriate level to begin the timing for the brew cycle. If this probe does not see water for 6 minutes the control
board will interpret this as an error. It will shutoff the solenoid valve, disable the control board and the heating light
will flash continually. The time required to fill the tank initially exceeds this time. Therefore this error will occur when
the unit is initially setup. To reset the safety circuit and enable control board simply hold down the brew start/stop
switch for 10 seconds. Error will clear.

2) Depress the brew start/stop switch. The tank lid has a second longer probe in it which is a heater safety probe. This
probe will tell the control board when the water level is high enough to supply power to the tank element. It also will
call for power to be shut off to the element should the water level fall below it. If the tank temperature adjustment is
in the off position or if the autoarm feature has been disabled the unit will continue to fill. Otherwise the brewer will
go into the autoarm mode and the heating light will begin to flash. This indicates that the unit is in the brew mode but
is not up to temperature (Note: To accelerate the set up time the "tank temp" Adjustment dial may be rotated to the
off position momentarily until the fill cycle begins and then turned back). When the tank reaches the preset
temperature the fill portion of the brew cycle will begin. The tank lid must be in place for proper unit operation. When
water begins to flow from brew basket the brew cycle may be canceled by depressing the brew start/stop switch.
Allow water to finish draining from the unit and then empty the container.

3) The GXD Model brewer incorporates an independent manual By-Pass system for the Left and Right brew systems.
By-Pass is turned on to maximum unless customer specified.
Procedure:
By-Pass is turned on to maximum unless customer specified.
Procedure:
a) Remove the top cover and locate the Black adjustment knobs
shown in the figure at right.
b) Turn the knob clockwise to shut off and then counter clockwise 1
¼ turns; this should open the by-pass approximately 10%.
Turning ¼ turn will result in a 5 to 10% increase.
Turning ¼ turn will result in a 5 to 10% increase.
c) To calculate your by-pass, refer to the chart below for available
range.
USE CAUTION WHEN WORKING WITH VERY HOT WATER.
Remove the brew basket from the brew rail and position a metal
container to collect the water from the sprayhead. The by-pass
outlet is located in the right corner of each brew plate. Position a
measuring container under the outlet and initiate a brew cycle,
water will begin to flow out of the sprayhead and by-pass. At the
point the by-pass begins flowing freely, time and collect 30
seconds of water and compare the volume with the chart below
to determine your % of by-pass.
