COMMISSIONING THE UNIT
Pressurizing the CO2 System
The Viper unit is designed to operate on a CO2 input pressure of 75 +/- 1 psig. If
the installation location has either an independant tank and regulator or a bulk
CO
2 supply that feeds more than one machine, a shutoff valve and secondary
regulator must be placed in the line from the bulk supply to the Viper unit to
reduce the CO
2 pressure at the unit to 75 +/- 1 psig. Perform the procedure in
Table 11 to pressurize the CO
2 system.
Table 12 provides guidelines for machine settings based on general syrup type.
Several factors, including syrup formulation, level of citric acids, etc, will impact
settings. These settings are to provide initial adjustments to achieve product
overruns in the 80-120% range.
NOTE: For citric syrups, adjust the CO
2 pressures down by 2-4 PSIG from
the above to compensate for the lower CO
2 adsorption.
Table 11
Step Action
1 Open the CO2 cylinder valve slightly to allow lines to slowly fill with gas.
When lines are fully pressurized, open the CO2 cylinder valve all the way
until it back-seats itself (this prevents leaks from the valve).
2 Adjust the CO2 cylinder regulator for the unit to 75 +/- 1psig at the unit. DO
NOT TURN THE SYRUP CO2 REGULATOR ON AT THIS TIME.
3 Check and set the CO2 barrel regulators (located on the front of the unit
behind the splash panel) so that the pressure for each barrel is set to 36
psig for sugar based syrups.
4 On the right side of the unit, verity that the expansion tank CO2 regulator is
set to 30 psig, if not correct. NOTE: The expansion tank regulator should
not be adjusted when pressure is applied to the barrels.
5 The Do Not Drink and Out of Product lights remain on. The “H2O Out” mes-
sage should clear and the “Syrup Out” message displays.
6Check for CO2 leaks by turning off the CO2 supply to the Viper. Wait at least
3 minutes and check the CO2 cylinder gauge to see if the pressure has
dropped.
7 The Do Not Drink and Out of Product lights remain on.
