Deflation Methods - Aqua Lung Rapid Diver User Manual

DEFLATION METHODS

Throughout the course of a dive, it will be necessary to release air from the BC
using one of the three methods described in the following instructions. Each
method uses a valve that is in a different location. The method you choose at
any time may depend on whether you are making your initial descent feet first,
head first or maintaining neutral buoyancy underwater. Always remember to
utilize the valve that is at the highest point on the bladder, depending on your
position in the water.
The deflation rate of the power inflator is as follows: 20 Newtons per second.
Deflation (Oral Inflator)
To deflate the BC using the oral inflator, lift the inflator body to its highest
possible position (above the head). Press the oral inflator button (Fig. 22b) to
start venting air. To close the valve, release the oral inflator button.
Deflation (Inflator Dump Valve)
Your BC comes equipped with a inflator dump valve (Fig. 23f) on the top of
the airway assembly. The inflator dump valve has a cable inside the hose that
attaches the lower inflator to a dump valve at the top of the airway assembly.
You can vent air from the BC by gently pulling straight down on the lower
inflator. To close the valve, stop pulling down and release the inflator.
CAUTION: It is not necessary to use excessive force when releasing air from
the inflator dump valve. Travel of the valve is limited and pulling harder will
not increase the air flow. Excessive force can damage the inflator dump valve
mechanism, rendering it inoperable.
