Additional Information


The Pressure Alarm System is designed to indicate low inlet pressure in Thermco gas mixers built for two gases. The gases must be non-flammable and non-corrosive. If oxygen is used, the Pressure Alarm System must be ordered cleaned for oxygen service.


Improper use of this product can cause death, serious injury, or property damage. Personnel dealing with this equipment should read and understand warning labels and instruction manuals provided by Thermco. Only personnel familiar with industrial gases should attempt to install or service this equipment. Gases are under pressure and therefore the hazards associated with pressurized systems exist. Gases from high pressure cylinders must be reduced to the specified pressure before entering the equipment to prevent the possibility of equipment damage and personal injury.

Only use oxygen in gas mixers specifically designed for oxygen service. Gas mixers not designed for oxygen service cannot be converted to oxygen service.

Flammable, toxic, liquid or corrosive gases should not enter this equipment.
