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 Apeks
Dealer or Distributor.
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 Apeks Dealer or Distributor.
INSPECTION CHECKLIST
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 each Flat 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.
4. Make a final check of the cylinder band’s tension to ensure that it is securely fastened to the cylinder.
Retighten if necessary.
5. Before entering the water, check both weight pouches, 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.
