The recommended MaxFlow regulator inlet (or bottle regulator outlet pressure) is 850 PSI. With a lower input pressure, the regulator works, but full function cannot be guaranteed. Do not use an input pressure higher than 900 PSI.

The function of activation/deactivation and regulation is performed by the Allen screw located in the regulator head. Slowly screwing clockwise will first open the cylinder and then increase the pressure. The regulator operates with output pressures of 0-225 PSI.

The MaxFlow regulator is equipped with an adjustable safety valve. It can be adjusted by unscrewing the red cover nut, under which the adjustment screw is located. Turning clockwise increases the pressure at which the safety valve begins to leak.

Max Flow is not designed for CO2.
