PAPR INSPECTION AND DONING INSTRUCTIONS Max Air Helmet High Efficiency PAPR 1. Check to make sure that the PAPR unit is assembled in the carrying case and that all of the following components are present: - Helmet unit (pre-assembled high efficiency shroud and power cord) - Battery pack and Waste Belt 2. Adjust the rear headband ratchet knob counterclockwise to allow the headband to easily fit over the head . 3. Flip the backside of the Filter hood up and over the Helmet to the front. Grasp the helmet on each side with the filter hood lens facing the floor and the rotary adjustment knob facing the ceiling. 4. Place the helmet firmly on the head. Position the helmet so that the front head band is within ½ inch of the eyebrows, and the rear headband is resting on the back of the head. 5.
