DEFLATION METHODS USING A POWERLINE INFLATOR
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, headfirst, 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.

Deflation Via Oral Inflator

To deflate the BC using the oral inflator, lift the Powerline inflator
body to its highest possible position (above the head). Press the oral
inflator button (a) to start venting air. This method is most effective
on the surface when starting the initial descent.

Deflation Via Powerline Dump Valve

Inside the power inflator's hose is a cable that attaches the power inflator to the Powerline Dump Valve
at the top of the airway assembly. You can vent air from the BC by firmly pulling straight down on the
power inflator. This dump valve provides an effective and convenient way to vent air from the BC while
in either an upright or facedown swimming position.
