Deflation (Dump Valve)
Your BC comes equipped with a dump valve / over pressure relief valve
(OPRV) (Fig. 23g). The primary function is to relieve excess air pressure
inside the bladder. If the internal pressure exceeds the spring pressure, the
OPRV automatically opens to release air, preventing damage to the BC. The
dump valve can also be opened manually by pulling on the pull knob and
cord assembly to quickly dump air from the BC. To close the dump valve,
release the knob and cord assembly.

CAUTION: The proper function of the over pressure relief valve (OPRV) is vital
to prevent damage to the BC bladder. Unauthorized service or tampering may
render this valve inoperable and could cause the bladder to leak or burst. This
type of damage is not repairable and is not covered under warranty.
WARNING: Most training agencies recommend that you should descend in an
upright, feet-first position, in order to maintain a slower and more controlled
descent. This is especially true if you experience difficulty equalizing your ears
or if you are descending in low visibility conditions.
