7. SECOND STAGE REGULATOR
The second stage regulator attaches to the facepiece using the Air Klic system.
This mechanism automat-
ically locks when the regulator is pushed into the Air
Klic on the facepiece. The second stage regulator is
activated by the “First Breath
On” mechanism or by the manual override button on the front of the regula-
tor. To disengage the regulator from the facepiece two steps need to be followed. First,
press the black
rectangular shut-off button at the twelve o'clock position on the
regulator to stop the air supply. Second,
depress both opposing gray release
buttons at the twelve and six o'clock positions and pull the regulator
from the
facepiece.
The second stage regulator is capable of supplying the user in excess 350 liters
per minute of breathing
air. The large red knob on the regulator controls the
adjustable bypass valve. Turning the bypass valve
knob counterclockwise provides a constant flow of breathing air. The bypass valve is intended for
emer-
gency use only to supply breathing air should regulator failure occur. The bypass valve is capable for
supplying a maximum of 130 liters per minute of breathing air. When not in use the regulator should be
stored in the regulator
belt clip located on the left waist strap. The second stage regulator supplies
breathing air via an intermediate pressure hose with a quick connect fitting.
