Aqua Lung WTX Buoyancy System - Manual (Page 41)

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. If you have the optional SureLock weight system on your WTX harness, check both weight pouches
to ensure that they are correctly fastened before entering the water.
WARNING: If you can hear any leaks, or if the bladder begins to deflate within 10 minutes,
DO NOT attempt to use the BC until it has received service from an authorized dealer.
NOTE: If applicable, perform steps 1-3 above on the second bladder of the redundant
bladder model.
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 or valves until it has received a complete
inspection and service from an authorized dealer.
INSPECTION CHECKLIST
1. Connect the power inflator to a source of clean 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 over-pressure relief (OPR) valves by pulling on the attached ball 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 valves by repeatedly inflating the BC to ensure that they open to relieve excess
pressure, yet close immediately afterwards to allow the bladder to remain taut and fully inflated.
3. Check the function of the oral inflator button and over-pressure relief / manual dump valve (See Deflation
Methods) 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 for any leaks.
