BC Inspection Check List 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. | ||||||||||
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. | ||||||||||
