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 and center.

FILLING THE CHAMBER
A. Access "CO
2
SOL" by going to the "SERVICE MENU\MANUAL ON/OFF" section of the service
menu.
B. Displace the air in the chamber with CO
2
by activating the CO
2
solenoid.
1.
Pull and hold the relief ring until the escaping, rushing air sound almost stops; then release
the ring. Allow the pressure to rebuild in the tank.
2.
Repeat this procedure at least two more times until the air has been displaced by the CO
2
.
Remember to deactivate the CO
2
solenoid upon completion.
C. Repeat steps A and B above for the center and right side of unit. Remember to deactivate the
CO
2
solenoid upon completion.
D. With CO
2
in the chamber, press the left side "FILL" button to begin filling the chamber with prod-
uct. If the chamber does not fill, gently pull the Relief Ring until filling begins and then release.
As the chamber fills, the pressure in the chamber will increase until it rises above the PSI fill
point. At this point, the chamber will stop filling and the LCD will readout "Fill Hold". It will then
be necessary to pull the relief ring to relieve the pressure and allow filling to continue. Slowly
pull the relief ring until the pumps activate, then release. Repeat the venting process until the
chamber is 90% full (level with relief valve), then press Fill button to turn OFF.
Fill one (1) chamber at a time.
E. Repeat steps A, B, C, and D for the center and right chambers.
F.
Press the "DEFROST" and then the "RUN" buttons for all barrels to begin the freezing process.
The beater motors will begin to run but the compressor will wait for two (2) minutes before
starting. After the two (2) minute waiting period, the machine will defrost and then begin the
freeze cycle.
G. After an initial freeze down [approximately ten (10) to twelve (12) minutes], the product will be
frozen and ready to dispense.
NOTE
On an initial freeze down, products must be given adequate time to absorb CO
2
. Until CO
2
is
properly and adequately absorbed, drinks could be too "wet" or too "heavy". If adjustments are
necessary, refer to section 9.
H. Re-check CO
2
, Water, and Syrup lines for leaks.
