Pre-Dive Inspection - Aqua Lung BC 1 User Manual

PRE-DIVE INSPECTION

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, valves or
any components until it has received a complete inspection and service from an
Authorized Aqua Lung Dealer or Distributor.
1. Visually inspect the entire BC for cuts, punctures, frayed seams, excessive
abrasion, damaged or missing hardware and other damage of any kind.
2. Connect the inflator to a source of clean air, via the MP quick disconnect
hose. Inflate the BC intermittently to ensure that the airflow is unobstructed
and that the airflow stops completely when the inflator button is released
(See Inflation Methods).
3. Manually operate the dump valve by pulling on the pull knob and cord assembly
to release air from inside the BC, then fully inflate the BC until the (OPRV) opens
(See Deflation Methods). Examine the operation of the (OPRV) / dump valve by
repeatedly inflating the BC to ensure the valve opens to relieve excess pressure,
yet closes immediately afterwards to allow the bladder to remain taut and fully
inflated.
4. Push the oral inflator button to ensure a rapid and unobstructed exhaust
from the valve (See Deflation Methods). Fully inflate the BC once again and
disconnect the MP hose from the power inflator. Let the BC stand for 10
minutes and listen for any leaks.
WARNING:
deflate within 10 minutes, DO NOT attempt to use the BC until it
has received a complete inspection and service.
5. Make a final check of the cylinder band tension to ensure it has been secured
properly. Re-tighten if necessary.
6. Before entering the water, check both weight pouches (if equipped) to ensure
that they are correctly fastened to the BC.
WARNING:
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.
If you can hear any leaks, or if the bladder begins to
