Aqua Lung Airsource 3 with Cut-off Valve - Manual (Page 12)

Normal deflation of the BC should be accomplished by utilizing the Trim Grip™,
as well as dump valves. Please refer to your bc owner's manual for model-spe-
cific valve locations. Air can also be vented manually through the mouthpiece by
pressing the oral inflate/deflate button.
Deflation by the Relief Valve
The Relief Valve provides the primary convenient means for exhausting air from
the bc. The valve opening located at the top of the bc must be above the body
when submerged for venting to occur. This is best achieved by moving toward
an upright position when venting air.
1. To activate, simply pull downward on either the Trim
grip™ or the Airsource body. (figure 11). This action
transmits force through internal stainless steel cables and
opens the valve at the shoulder to allow air to vent from
the bc.
2. releasing the Trim grip™/body closes the valve.

WARNING: If during your pre-dive check, or at any time during
the dive you find that the Relief Valve will not fully close and
seal or will not fully open and vent air, dO NOT continue the
dive. Continuing the dive under these circumstances could re-
sult in serious injury or death.
WARNING: The Airsource does NOT come equipped with an
Over pressure valve. It must be rigged to a BC that features an
Over pressure valve. If you have questions regarding the fea-
tures of your BC, ask your local authorized Aqua Lung ® dealer.
NOTe: It is not necessary to exert an excessive down-
ward pressure to activate the Relief Valve. When you
pull on the Trim Grip™, you will feel the hose stretch,
allowing the exhaust valve to open. The travel of the
valve is limited to less than 1/4". Pulling harder will
not increase the air flow. Maintain downward pressure
until the desired buoyancy is reached. It is not neces-
sary to raise your arm overhead when using the Relief
Valve system.
