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 by orally inflating the BC. Fully inflate the BC once again, and disconnect the i3 inflator from the compressed air supply and listen closely for any leaks.

warning 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 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 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.
