PRE-DIVE INSPECTION FOR BC'S WITH I3 INFLATION SYSTEM
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 i3 Control Unit to a source of clean compressed air via the MP quick disconnect hose.
Lift up and release the lever intermittently to ensure that the airflow is unobstructed, and that the
airflow stops completely when the lever is released. Push down on the lever to make sure the BC is
venting air.
2. Manually operate the Flat E-Valve by pulling on the attached knob and cord to release air from
inside the BC, and then fully inflate the BC until the Flat E-Valve opens. Examine the operation of
the Flat E-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, to ensure rapid unobstructed exhaust from the oral airway
assembly. Fully inflate the BC once again, and disconnect the i3 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.
