Heptafluoropropane HFC-227EA is one of the more commonly used fires extinguishing systems in gas fire extinguishing systems. It is colorless, odorless, non-conductive, non-corrosive, and has no damage to sophisticated equipment and valuable properties. 1. Suitable for fire fighting: \u2460Electrical fire \u2461Solid surface fire \u2462Liquid fire \u2463A gas fire that can cut off the gas source before extinguishing the fire 2. Matters needing attention: \u2460. Before the system is officially running, the safety pin of the pilot valve on the fire extinguishing agent container valve must not be pulled \u2461. When the system is in the formal power-on simulation action, do not install the electromagnetic drive device, just turn on the power and observe the action of the drive device \u2462. The electromagnetic drive device must be connected to the power supply before the drive device is installed, and the drive gas pipeline must be disconnected. When the electromagnetic drive device is installed and confirmed to be correct, then the drive gas pipeline should be connected \u2463. When carrying out the emergency start operation of the manipulator, strictly follow the "operating procedure" described above, and pay special attention to first open the selector valve, and then open the container valve of the fire extinguishing agent bottle group, so as not to cause injury to the lock lever when it is started by mistake.
