Warning
Your PSLV is not a lift bag. DO NOT use it to bring heavy objects to the surface.
Doing so may cause permanent damage to the PSLV .
Warning
This PSLV is designed for use with carbon dioxide cylinders only. Any use of
gas mixtures may cause corrosion, deterioration, and/or premature aging of the PSLV
leading to component failure of the metal and rubber parts. The component failures could
lead to a loss of buoyancy control and/or pressure integrity of the PSLV resulting in injury
or death.
Warning
DO NOT inhale from your oral inflator. The PSLV is not a breathing appa-
ratus or a source for emergency air. Air in the PSLV may contain harmful contami-
nants or gasses, which could cause suffocation or air embolism injuries
Warning
Before every dive day, perform a complete pre-dive inspection according to the
procedure prescribed in this manual to ensure that all components are functioning properly
and no signs of damage or leaks are present. If you find that your PSLV is not functioning
properly or is damaged, remove it from service until it can be repaired by OSS.
Confirm that each cylinder is full:
Never assume the CO2 inflation gas is in the cylinder. The burden of inspection of the cylinder is yours. In
order to know if the gas is in the cylinder the first step is to remove the cylinder from the inflation system
or package and look at the narrow end; the puncture surface. This surface is where the inflation system
penetrates and allows the gas to fill your inflatable. If this surface has any puncture marks, holes, or any
sign that is has been pushed in DISCARD IMMEDIATELY.
Every CO2 cylinders has a ‘Minimum gross weight’ marked on the side of the cylinder. This marking is
the sum of the empty steel cylinder AND the weight of CO2 that is supposed to be contained in the
cylinder. Ultimately, weighing is the only accurate method known to ensure that the full CO2 charge is in
the cylinder. A scale, such as a digital postage scale, may be used if it is accurate enough for the
intended measurement. For example: A cylinder with a marked minimum gross weight of 68g MUST
weigh 68g OR GREATER, never less. If you weigh a cylinder and the actual weight is less than the
marked weight, remove it from service and discard it. Typically, CO2 filled cylinders do not lose their
charge unless: punctured, rusted, crushed, overheated, or altered.
Handling and storage of cylinders
Use only “low force” piercing cylinders designed specifically for automatic life vests.
CO2 cylinders are single use; dispose and recycle spent cylinders. Handle cylinders carefully. Do not
modify or erase marks or other items on cylinders. Store cylinders in a dry and well ventilated area. Keep
cylinders away from corrosive fluid. Keep cylinders away from direct sunlight at an ambient temperature
of 0 to 40 degrees C (32 to 104 degrees F).
Specific Warnings Regarding Carbon Dioxide (CO2) cylinders
Precautions for use in freezing temperatures:
The expansion of the CO2 gas expands in hot
weather, and contracts in cold weather. At -30 degrees F (-33 degrees C, the baldder fill is just 87% of
the volume created at 70 degrees F (22 degrees C.)
Under freezing conditions, the CO2 gas charge fills the bladder more slowly and less completely.
Warning
DO NOT force theCO2 cylinders into or out of the actuator. Excessive force
may damage the threads. To help loosen the threads, try soaking the apparatus in a 1-1
solution of warm water and vinegar for 3 hours.
