Revision Date 8/28/2018
1. Critical Safety Overview
Throughout these instructions, this symbol is used to indicate that the instructions are critically
important to your safety and the safety of your system. Failure to follow the instructions as written
can result in a rapid release of high pressure CO
2
potentially causing equipment or personnel
damage.
WARNING
Subcritical and Supercritical CO
2
systems operate under high pressure. Operators must be fully trained and
familiar with the system. Failure to operate the system can result in equipment damage and/or bodily injury.
WARNING
Subcritical and Supercritical CO
2
systems use large amounts of CO
2
during operation. Ensure that system is
installed in a well-ventilated area to prevent buildup of CO
2
which can cause asphyxiation. Use of a CO
2
monitor
is strongly recommended.
WARNING
Opening a vessel under pressure can result in a rapid release of pressure and ejection of the material inside the
vessel. DO NOT ATTEMPT TO OPEN A VESSEL UNDER PRESSURE! Always make sure a vent path for the
vessel is opened and the corresponding pressure gage reads zero prior to loosening the vessel hammer unions
or closure bolts.
WARNING
Subcritical and Supercritical CO
2
systems are designed to operate indoors. Extreme temperatures (below 60°F
and above 80°F) will negatively impact the functionality of the system. The environmental temperature range is
for the system, chiller, pump and CO
2
bottles.
WARNING
Only use Propylene Glycol and distilled water in the chiller and cooling system. Never use Deionized Water in
the chiller or cooling system.
WARNING
Always wear safety glasses when operating and servicing the system.
