air may not escape from the manual Dump Valve in all swimming positions. If the air
bubble in the BC is above the Manual Dump Valve, as when the diver is in a horizontal or head
downward position, then the air may not escape from the valve. Failure to vent air from the BC may
cause an ascent at a time or speed that could cause injury or death. Make sure that the valve you
use to vent the BC is at the highest point of the air bubble.
over pressure Valve (outlet 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. These valves have a lanyard cord and pull knob that allows manual dumping
of air and are referred to as Dump Valves.
shoulder Dump Valve
SUBGEAR Buoyancy Compensators have an Over Pressure Valve located on the shoulder of the BC.
To operate this style of Over Pressure Valve, orient the valve to a position higher than the air bubble in the
BC. Pull gently on the Pull-Dump Assembly until the desired amount of buoyancy is reached. Stop pulling
to close the valve.
Lower Dump Valve
Over Pressure Valves located at the lower rear of the BC may be equipped with lanyards and pull knobs.
These Lower Dump Valves 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.
5. GeneraL InFormatIon on aDJustments
adjust the Bc so that it does not restrict your breathing when fully inflated. 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.
Consult a certified SCUBA instructor or the retail facility where the BC was purchased for help.
Waist and Front (chest) closures
Waist closures may use an, Adjustable Front Closure Buckle with a "squeeze to release" feature, a hook-
and-loop closure on a cummerbund, or both. Hook-and-loop closures are fastened by placing the hook
and loop panels on top of each other and applying moderate pressure. Waist closures may need to be
adjusted at depth if a neoprene suit is worn by the diver.
Front (chest) closures on the BC are used to keep the BC in a low drag configuration. These front
closures adjust with webbing tails located in the front of the BC.
adjustable shoulder Bcs
Shoulder straps may be adjustable on your BC. These straps adjust by a length of webbing passing
through a locking feature on a quick release buckle. Tighten buckles by grasping the free end of the
adjustment webbing and pulling firmly downward. Lift the front of the buckle upwards while wearing the
BC to loosen.
