BRIXING
A. With the unit powered up, press both of the
"OFF" buttons on the display to ensure the
unit is in the OFF state.
CAUTION
CHECK ALL SUPPLY LINES TO ENSURE
THAT THEY ARE CONNECTED TO THE
CORRECT FITTINGS. IF LINES ARE NOT
CONNECTED PROPERLY, COMPONENTS
WILL BE DAMAGED.
B. Open the water supply valve and check all
water line connections for leaks.
C. Connect the BIB connectors, or the syrup
and CO
2
couplers, to figal tanks. Check all
syrup supply connections at the rear of the
machine for leaks

D. Open the CO
2
tank valve and adjust the primary tank regulator until the "CO
2
Pressure"
readout in the "SERVICE MENU\ READOUTS\ COMMON READOUTS" reads 70-72 PSIG
(482.6 KPa to 496.4 KPa). Check all CO
2
line connections for leaks.
E. Adjust the CO
2
secondary regulator (located inside the machine) to read 28-32 PSIG (193.2 to
220.8 KPa) according to the LCD readout found in the "REGULATED CO2" readout in the
"SERVICE MENU\ READOUTS\ COMMON READOUTS" section of the LCD menu.
IMPORTANT!
SET ALL PRESSURES USING THE LCD READOUTS ON THE UNIT - NOT BY THE GAUGES
ON THE REGULATORS!
F.
Close Syrup flow controls by backing (counter-clockwise) controls all the way out (see Figure
6.4).
G. Using water only, check the flow rate (through the sample valve) and set water flow to provide
a flow of 15 ounces in 10 seconds using a graduated container. Do this for both left and right
side flow controls. Turn control adjustment screw
clockwise to increase flow or counter-clock-
wise to decrease flow.
H. Pre-set Syrup flow by turning in Syrup flow controls 2 1/4 turns (clockwise).
I.
Place a container under the sample tube and fully depress the sample valve until a good water
and syrup mixture is obtained (see Figure 6.5).
This sample should be discarded.
J.
Place a sixteen (16) ounce (0.473 l) cup under sample tube and fully depress the sample valve
until 9 - 12 ounces (0.266 - 0.355 liter) have been dispensed into cup.
K. Measure the brix with a refractometer. Set brix to between 13.5 and 15.0 by adjusting the syrup
brix flow controller
clockwise to increase brix level or counter-clockwise to decrease brix level.
If the brix requires adjustment, discard
a sample before checking the brix
again.
NOTE
Do not adjust the brix with the water flow
control setting unless you are unable to
obtain the desired brix with adjustments to
the syrup flow control.
Brix reading is affected by temperature.
Samples taken from the chamber should
be at the same temperature as from the
sample valve.
L.
Repeat steps I, J, and K for other side.
