Giacomini A7B is a fire protection device designed to break its water stream into small droplets, increasing the surface area and rate of heat absorption. This process helps to smother fires by displacing oxygen. The A7B has a 2 1/2" hose thread and is made of rough brass. It can be installed on a properly sized threaded end coupling and should be inspected periodically for damage or corrosion.
The A7B can be operated by hand, never using a torque bar or other device to exert pressure. Excess torque may damage the seat and/or body. To operate, turn the nozzle clockwise, following the arrows on the body. To shut off, turn counter clockwise. Do not exceed 50 Nm (440 lbf∙in) torque for brass nozzles.
