This document outlines the installation, operating, and servicing instructions for Amerex Carbon Dioxide Portable Extinguishers, specifically models 321M, 322, 322NM, 330, 331, and 332.
These devices are portable fire extinguishers designed to combat fires by diluting the surrounding atmosphere with inert carbon dioxide (CO2) gas, thereby reducing oxygen levels below what is required for combustion. This method is effective for certain types of fires, but users are warned about the potential for oxygen deficiency in unventilated spaces, which can lead to loss of consciousness. Skin contact with CO2 is also cautioned against due to its extremely cold temperature, which can cause burns or frostbite. The extinguishers are intended for immediate use and should be recharged immediately after any use.
The manual provides approximate discharge times and ranges for different extinguisher sizes:
The operation of the extinguisher involves a simple, multi-step process:
The manual emphasizes the importance of regular inspection, maintenance, and proper recharging.
The manual includes a troubleshooting guide for common leakage problems, providing corrective actions such as replacing O-rings, valve stem assemblies, safety relief nuts, or contacting Amerex for cylinder issues. It reiterates the warning about depressurizing the extinguisher completely before attempting repairs and the importance of using proper torque for valve assembly.
