Deflating the BC with the Manual Dump Valve
(For Units fitted with the SCUBAPRO Manual Dump Valve)
Stop and assume an upright position in the water. When in position, open the Manual Dump Valve
by gently pulling downward on the Oral Valve/Power Inflation Valve Assembly. 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.
!
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.
Deflating the BC with the Oral Valve (BPI)
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 Oral Valve
button and visually confirm that air is escaping from the Inflator. For best control, let air out in a
series of short, measured amounts while observing the effects on your buoyancy.
!
WARNING
• With all deflation methods, only keep the valve open as long as 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.
Over Pressure Valve Operation
The Over Pressure Valve prevents over-inflation of the BC. If the internal pressure exceeds 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 (OPV).
Shoulder Valves
SCUBAPRO X-Tek bladders may have either an elbow or an overpressure valve on the left shoulder
that can also act as dump valves. The dump valve on the left shoulder is activated either by:
a) Pulling gently on the hose assembly.
b) If an OPV dump valve is not present on the left upper bladder then the diver should deflate
the BC using the manual dump function on the inflator.
Lower Dump Valve
Pressure Valves located at the lower rear of the bladder are equipped with lanyard and pull knob.
This lower Dump Valve can be manually activated when the Diver is in a horizontal or head down
orientation in the water, positioning them at the highest point of the air bubble.
