WARNING:
CO
2
displaces oxygen. Persons exposed to high concentrations of CO
2
will experience tremors, followed by loss of
consciousness and death. It is very important to prevent CO
2
leaks, especially in small unventilated areas. If a CO
2
leak occurs
ventilate the area before fixing the leak.
NOTE: There are two CO
2
delivery systems available: High Pressure Cylinder; Low Pressure Bulk System.
High pressure Cylinder requires a primary regulator with a minimum inlet pressure of 500 psi.
Low Pressure Bulk System requires a secondary regulator with a maximum inlet pressure of 200 psi.
NOTE: CO
2
connections require 3/8” I.D. tubing. All hoses must reach the back of the unit plus an adequate amount of
extra tubing to allow the unit to be pulled out for servicing.
NOTE: Use a dedicated secondary regulator adjusted to 75 ±1 psig to supply the unit.
CO
2
Connections
Use a source-dedicated secondary regulator, fittings and clamps to connect the CO
2
line to the unit, as shown in Figure 8. Set the
regulator for 75 ±1 psig at the unit. Run the tubing for the CO
2
from the secondary regulator to the unit and make all appropriate
connections. Ideally, locate the regulator within 3 ft. of the unit. Another secondary regulator is to be used to supply the Bag in Box
pumps. It is to be set to 75 psig, not lower. Do not turn on the CO
2
supply to the unit.
