High concentrations of carbon dioxide can
cause asphyxiation. The use of CO
2
monitors
and alarms is recommended for areas where
CO
2
can collect.
The CO
2
gas supply should be 99% pure and
should not contain a siphon tube. Gas pressure
to the unit must be regulated to 15-20PSI.
Failure to do so could cause tubing to burst.
Connecting a CO
2
supply (CO2C302)
The CO
2
supply should be 99% and not have siphon tubes. CO
2
pressure should be
regulated to 15-20 psi. CO
2
tank regulators can be purchased through CARON
customer service. Once the cylinder regulator is installed, connect the outlet of the
regulator to the hose barb fitting using the tubing and clamps provided. An inline
HEPA filter is provided to remove any contaminants in the CO2 gas supply. Check the
connections closely for leaks.
If the unit is equipped with a built in gas guard system, there will be 2 gas inlets. Each
of the inlets should be connected to an individual gas tank as described above.
