8. OPERATION
8.1 Inflation
Inflating the BC with the Power Inflation Valve
To inflate the BC, press the Power Inflation Valve Button (fig. 6-P). Air should enter the BC.
For better control during inflation use short bursts of air by repeatedly pressing and releasing
the PIV button.
Inflating the BC with the Oral Valve
The Oral Valve is found on the end of the airway. It allows you to inflate your BC with your
exhaled breath. Use of this valve for inflation is recommended on the surface, or on land
prior to diving. It may be used when you cannot, or do not wish to add air to the BC with
the Power Inflation Valve.
1. First exhale a small amount of air into the mouthpiece of the valve to purge any water that
may be trapped there.
2. With the same breath, continue to exhale while deeply depressing the Oral Inflation Valve
Button (fig. 6 - O).
3. Release the Oral Valve Button when you inhale fresh air.
4. Repeat steps 2 and 3 until the desired amount of buoyancy is reached
8.2 Deflation
Deflating the BC with the manual dump valve on the elbow
Stop and assume an upright position in the water. When in position, open the Manual Dump
Valve by:
a. pulling gently on the hose assembly (fig. 7 - A).
It is not necessary to use excessive pressure to pull on the hose assembly. Valve travel is
limited and pulling harder will not increase the air flow. To close the Manual Dump Valve,
stop pulling downward, and release.
b. pushing on the button that protrudes out of the valve casing (fig. 7 - C) (Patented): this
system could be useful also to purge air of another diver having problems (panic, beginner
diver, unconsciousness, etc.).
