Aqua Lung Airsource Quick Disconnect - Manual (Page 11)

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 specific 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 10). 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.
DEfLATION
Figure 10
NOTE: It is not necessary to exert an excessive downward pull
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 a downward pull until the
desired buoyancy is reached. It is not necessary to raise your arm
overhead when using the relief Valve system.
WARNING: The Airsource does NOT come equipped with an Over pres-
sure valve. It must be rigged to a BC that features an Over pressure
valve. If you have questions regarding the features of your BC, ask your
local authorized Aqua Lung ® dealer.
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 result in serious injury or death.
