Pre-Dive Inspection For Bc's Using Powerline Inflator; Bc Inspection Checklist - Aqua Lung Balance User Manual

PRE-DIVE INSPECTION FOR BC'S USING POWERLINE INFLATOR

Before each use, the BC must be given a thorough visual inspection and functional test. NEVER dive
with a BC that shows signs of damage to its bladder or valves until it has received a complete inspection
and service from an Authorized Aqua Lung Dealer or Distributor.

BC INSPECTION CHECKLIST

1. Connect the power inflator to a source of clean, compressed air via the MP quick disconnect hose.
Depress and release the inflator button intermittently to ensure that the airflow is unobstructed, and
that the airflow stops completely when the button is released.
2. Manually operate the overpressure relief (OPR) valve by pulling on the attached knob and cord to
release air from inside the BC, and then fully inflate the BC until the OPR valve opens. Examine the
operation of the OPR valve by repeatedly inflating the BC to ensure that it opens to relieve excess
pressure, yet closes immediately afterward to allow the bladder to remain taut and fully inflated.
3. Check the function of the oral inflator button and Powerline dump valve, to ensure a rapid and
unobstructed exhaust from each valve. Fully inflate the BC once again, and disconnect the power
inflator from the compressed air supply and listen closely for any leaks.
WARNING: If you can hear any leaks, or if the bladder begins to deflate within 5-10 minutes, DO
NOT attempt to use the BC until it has received service from an Authorized Aqua Lung Dealer
or Distributor.
4. Make a final check of the cylinder band's tension to ensure that it has not loosened due to stretching.
Retighten if necessary.
5. Before entering the water, check both weight pouches, if applicable, to ensure that they are correctly
fastened to the BC.
WARNING: Loss of the releasable weight pouches can occur if they are not properly
secured. Involuntary release of both weight pouches can cause a sudden increase
in buoyancy causing a rapid ascent, and could lead to serious injury or death due to
arterial gas embolism, decompression sickness, or drowning.
