6.3 CO
2
Purge
Follow these steps to purge air from the barrels:
1.
Turn off the water and syrup supply shutoff valves to the dispenser (
Section 5.5
).
2.
Open the CO
2
supply device and adjust the regulator on one of the solution modules to 60 psig (414
kPag).
Note:
This regulator is a non-venting regulator. It will be easier to adjust by increasing pressure. If the reg-
ulator setting is reduced to lower pressure, the pressure must be vented by opening the solution module
solenoid manually using the Filling Sol 1 or 2 function in the Manual ON/OFF menu and pressing SELECT
before the set pressure is displayed on the pressure gauge. If the pressure reading does not reduce it will
be necessary to pull open the relief valve on the faceplate (
Figure 6.3
) to vent the pressure in the barrel.
3.
Open the solution module solenoid manually using the Filling Sol 1 or 2 function in the Manual ON/
OFF menu and pressing SELECT to fill the barrel with CO
2
.
4.
After about five (5) seconds, pull the pressure relief valve on the faceplate until no more gas is heard
escaping.
5.
Repeat previous step two more times.
6.
Close the solution module solenoid manually using the Filling Sol 1 or 2 function in the Manual ON/
OFF menu by pressing SELECT again.
Repeat process for other barrel.
6.4 Brixing
To ensure the dispenser produces a quality beverage and continues to operate properly, it is important to check
and adjust the brix of the beverage before use. All dispensers have been set correctly before leaving the fac-
tory, but the differences in syrup require the user to check or adjust brix settings. Use the following procedure
to set the brix for each barrel:
1.
Press the STOP ALL button on the display to ensure the dispenser is in the OFF state.
Note:
Check all supply lines to ensure that they are connected to the correct fittings
(Section 5)
. If
lines are not connected properly, components will be damaged.
2.
Open the water supply valve and check all water line connections for leaks.
3.
Check all syrup supply connections at the rear of the machine for leaks.
4.
Open the CO
2
tank valve and adjust the primary tank regulator to 70 to 72 psig (483 to 496 kPag).
Check all CO
2
line connections for leaks.
5.
Adjust the CO
2
solution module regulators (located inside the machine) to read 58 to 62 psig (400 to
427 kPag) as described in
Section 6.3
.
6.
Close syrup flow controls by backing the right adjustment screw on the solution module all the way
out turning it counterclockwise (see
Figure 6.2
).
7.
Turn off the CO
2
shutoff valve (see
Figure 6.2
).
8.
Adjust the water flow control two and one quarter (2 1/4) turns clockwise from the full counterclock-
wise stop.
