Altaros regulator output pressure can be set from 100bar (1450 PSI) to 150bar (2200 PSI) and after consultation of up to 170bar (2500PSI) which corresponds to the rotation of the screw behind value 150bar so that the line of the screw is pointing to the letter R. For a quick setting is on regulator engraved scale according to which the desired output pressure can be set. The total scale range of 100-150bar corresponds to approximately 2/3 turn Unscrewing, or screwing setting screw more than 1 turn may result in a malfunction of the regulation and scale will not show you regulated pressure. Groove on red marked half of setting plastic screw represents pointer which shows you currently set pressure on the scale. To change the pressure on regulator, just simply rotate the set screw with the flat screwdriver in the appropriate direction according to regulator scale.
