1.1 General
The 455 Balanced Regulator is an ultra-high per-
formance regulator, continuing the long line of
exceptional regulators from Kirby Morgan
construction and materials make it an extremely
rugged regulator.
NOTE: When storing the helmet for any length
of time, ensure that the Flex Knob, for adjusting
the regulator, is turned "out" fully counterclock-
wise to avoid stressing the bias springs. This will
prolong the life of both the inlet valve, seat, and
bias spring.

Check the regulator for adjustment and proper
function with the assembly complete, and sup-
plied with a breathing gas supply pressure of be-
tween 135 to 150 p.s.i.g
NOTE: 135 to 150 p.s.i.g. over ambient is the
standard supply pressure to be used when ad-
justing the 455 Balanced regulator.
1) Rotate the flex knob in, clockwise towards the
regulator body, until a clicking can be heard with
each full turn of the knob. This is an audible indi-
cation the tension of the bias adjustment spring
is as tight as it will get. The adjustment knob will
never bottom out or stop turning in this direction
and no damage to the mechanism will occur. The
clicking is an audible indication the adjustment
knob is fully positioned. Listen carefully for this
indicating click.
2) Ensure the supply pressure is connected and
properly adjusted to 135 to 150 p.s.i.g.
