Things to consider before removing the system from the box….
1. Know the properties and special handling requirements of the gas being used. Many specialty gases are
quite dangerous (flammable, asphixiant, etc.). Equipment failure or misuse may lead to problems such as a
release of gas through the regulator cartridge. Proper safety measures should be established to handle these
and other component failures.
2. Be sure that the assembly purchased is suitable for the gas and type of service intended. The regulator
label provides the following information:
a. Model number
b. Serial number
c. Maximum inlet pressure
Be sure that the equipment received conforms to the order specifications. The user is responsible for select-
ing equipment compatible with the gas in use, and conditions of pressure, temperature, flow, etc. Selection
information can be found in CONCOA’s Pressure and Flow Control Specialty Gas Catalog or online at www.
concoa.com. In addition, CONCOA representatives are trained to aid in the selection process.
3. Inspect the assembly upon receipt to be sure that there is no damage or contamination. Pay particular
attention to connecting threads. While CONCOA assembles system components to exacting leak- tight
standards, the customer should also inspect for any loosening of parts that may occur in shipping or instal-
lation. Loose parts may be dangerously propelled from an assembly. If there are adverse signs (leakage or
other malfunction), return the assembly to the supplier. While it is advised that soiled regulators be returned
for cleaning, simple external dust or grease may be removed by a clean cloth and if required with aqueous
detergent suitable for the application. If there are signs of internal contamination, return to the supplier.
