⚠WARNING
Keep sand and other contamination out of the Oral Valve mouthpiece and valve button.
Under certain conditions, contamination can cause the valve to not close completely.
If this occurs while diving, shake the valve while depressing it several times. If the
valve leaks or remains inoperable, terminate the dive. Diving with a leaking Buoyancy
Compensator or with valves that do not operate properly may result in a loss of
buoyancy control that could result in injury or death.
DeatingtheBCwiththeOralValve
Assume a head up position in the water. Raise the Oral Valve above and in front of your face.
(This insures the Oral valve will be positioned above the air bubble in the BC.). Depress the
OralValvebuttonandvisuallyconrmthatairisescapingfromthemouthpiece.Forbest
control, let air out in a series of short, measured amounts while observing the effects on
your buoyancy.
⚠WARNING
• The SCUBAPRO® Dual Manual Dump Valve (Patent) has a safety hand button that
releases air when pushed (g 7-C), in case of failure of the Manual Dump System
(broken cable, pin, etc.).
• With all deation methods, hold the valve open no longer than needed. This helps
prevent excess water from entering the BC.
• Do not depress the Oral Valve button when activating the Manual Dump valve, as
water may enter the BC through the Oral Valve mouthpiece.
LowerDumpValve(g.7-L)
An over Pressure Valve located at the lower rear of the BC is equipped with lanyard and pull knob.
This lower Dump Valve can be manually activated when the Diver operates them in a horizontal or
head down orientation in the water, positioning them at the highest point of the air bubble.
⚠WARNING
The deation devices with the maximum outow of gas are the shoulder valve g. (7-B)
and the lower valve (g 7-L).

the spring pressure in the Over Pressure Valve, the valve automatically opens and releases air
to prevent damage to the BC. The valve will automatically close when the internal pressure
goes below the spring pressure in the Over pressure Valve.
9. BC HARNESS ADJUSTMENT - GENERAL FEATURES
⚠WARNING
Adjust the BC so that it does not restrict your breathing when fully inated. Restriction
of normal breathing while wearing your BC could result in injury or death. Before each
use, check all bands, straps, quick-connect clips, and/or cummerbund for proper
adjustment to the user.
