Page 8: Safety Labels
Safety Labels The symbols used on the machine were developed by the International Organization for Standardization (ISO) and are defined below. These symbols may include yellow warnings triangles, blue mandatory action circles, or red prohibited action circles. Danger of Suffocation The recovery unit coverts gas CO to liquid CO in a closed system. - Page 9 Danger of Congelation The gaseous and liquid CO has a temperature down to -25° C (-13° F). The operator should be aware of the congestion with piping and elements inside the machine. Most pipes are insulated to keep the CO cold, but also work as safety protection.
- Page 10 Electrical shock Hazard When the main disconnect switch is in the ON position, the control panel is energized, and dangerous voltage is present internal ingress protection rating is at least IP2x/NEMA2. When the main disconnect switch is in the OFF position the line side of the switch remains energized. Wires that remain energized with the main disconnect switch in the OFF position are orange.
