Insert the regulator body and the hexagon panel nut into the panel mounting hole (ø10.5 mm for IR1000 series regulators and ø12.5 mm for IR2000/3000 series regulators) and retighten the shaft of the pressure adjustment knob.
For new IR-A series regulators, select option “H” (With hexagon panel nut (for panel mount)).
