Deflation Methods - Aqua Lung BC 1 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 BC, depending on your
position in the water.
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 (D) to start venting air. To
close the valve, release the oral inflator
button.
The deflation rate of the bladder is as
follows: 20 Newtons per second.
Deflation (Inflator Dump Valve)
Your BC comes equipped with a inflator dump valve on the airway assembly.
The inflator dump valve has a braided Spectra cord inside the corrugated
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:
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.
It is not necessary to use excessive force when releasing
