The piston assembly then moves toward the seat and the seal blocks the flow path and prevents the pressure from rising above 50 PSI This all occurs in a fraction of a second When gas is let out of the output cavity through the flow controlling device the pressure in the cavity drops The spring then pushes the piston assembly away from the seat to allow the oxygen to restore the pressure to 50 PSI and deliver the flow through the flow controlling device at prescribed rate This too happens in a fraction of a second In the unlikely event that the regulator does not regulate properly and should the internal pressure rise above 75 PSI or 95 PSI the relief valve will unseat and safely release gas through the vent holes in the side of the body NOTE The Flotec Medical Gas adjustable flow regulator is shown in enclosed drawings The internal regulator components are common to all Flotec Oxygen Regulators and Pressure Reducers IV DEFINITION OF STATEMENTS Statements in this manual proceeded by the following words are of special significance WARNING means there is the possibility of injury or death to you or others CAUTION means there is the possibility of damage to the unit or other property NOTE indicates points of particular interest for more efficient and convenient operation Always disassemble inspect clean and repair regulator components in accordance with these instructions Be aware of all the potential hazards associated with han
