Product Warnings Indicates a hazardous situation which, if not avoided, WILL result in death or serious injury. Indicates a hazardous situation which, if not avoided, COULD result in death or serious injury. Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. Addresses practices not related to personal injury. Disconnect power and disable flow before maintenance. Keep all personnel out of the Danger Zone, in front of the outlet of the monitor when the water source is attached. Dangerous flow velocities can cause serious injury. Use only for firefighting by trained operators. Read and follow the operating instructions before use. The monitor uses current limiting for both the monitor and nozzle. Use only appropriate Akron Brass Company nozzles. Replace the identification tags if they should become worn or damaged. The monitor, nozzle, logic box, control box, tether controller, and field adjustable stops are made for optimal performance. Do not alter in any manner. The monitor was designed for use with the Akron nozzle. Use of any other nozzle could affect the speed or operation of the unit and should be tested before being put into service. During freezing conditions the monitor must be drained to prevent damage.
