Installation and maintenance of the system must conform to the limitations detailed in this manual and be per- formed by an Authorized Pyro-Chem dealer. The Pyro-Chem Open Face Paint Booth System utilizes a monoammonium phosphate based dry chemical agent (specifically designed to suppress carbonaceous solid, liquid, gas or electrical fires).The system provides mechanical or electrical automatic actuation and can be manually actuated through a remote mechanical pull station. Upon actuation, the system discharges a pre- determined amount of agent to the hazard area. The shutdown of fuel and power to the hazard area is required upon system actuation. Exhaust fan(s) in the ventilation system must be shut off during system discharge to allow the proper concentration of agent to build up in the hazard area. TEMPERATURE LIMITATIONS The operating temperature range of the Pyro-Chem Open Face Paint Booth System is 32°F (0 °C) minimum to 120°F (49 °C) maximum. UL LISTING The Pyro-Chem Open Face Paint Booth Industrial Fire Suppression System has been tested to the UL Standard for Pre-Engineered Dry Chemical Extinguishing System Units.
