Important Notice - Tusa BC0103 Liberator Manuel D'utilisation

WARNINGS
• This information has been put together for your safety. Please
read and understand this manual completely before using
your new BCJ. If you have any questions concerning the use
or care of your BCJ contact your TUSA dealer or your diving
instructor.
• Prior to using this product you must receive training in
buoyancy compensation from an internationally recognized
educational organization.
• Misuse of this product may result in uncontrolled ascents,
descents, and loss of buoyancy and/or control that could lead
to serious injury or death.
• Please Note: This BCJ is not a coast guard approved surface
flotation device for all users and conditions.
• Always inflate your BCJ slowly to avoid uncontrolled ascents.
Rapid inflation can lead to loss of control upon ascent which
could result in air embolism, serious injury, or death.
• A significant amount of practice is required in order to
maintain a safe rate of ascent. The overpressure valve
cannot and should not be used to control or prevent
uncontrolled ascents.
• Do not add weights to the BCJ by placing them in the
pockets, or attaching in any other way. Doing so may prevent
you from easily releasing them in case of emergency.
Additionally, excess weight may reduce the buoyancy of the
BCJ and impair or prevent proper operation.
• Your cummerbund and attachment straps should be adjusted
for a comfortable and proper fit. Your BCJ should not restrict
your breathing when fully inflated. Check all bands, straps,
quick-disconnect buckle and the cummerbund for wear prior
to each use. Replace worn or damaged items before use,
using only an authorized scuba equipment repair facility.
• Modifying your BCJ or using after-market accessories may
prevent it from functioning properly and could result in
damage to the BCJ that may lead to serious personal harm
or death.
• Always examine your BCJ on a pre-dive, dive, and post-dive
basis. This will help identify equipment problems before they
occur. Virtually all BCJ equipment-related diving accidents
can be prevented by following these simple warnings and
precautions. It is also strongly recommended to have
your BCJ checked regularly by your TUSA dealer to
ensure that the inflator and other mechanical devices are
operating properly.
• It is important to have the APA system serviced every 12
months or after 100 dives (whichever comes first.)
Please see your TUSA dealer for overhaul.
• This equipment is designed to use standard air mixtures
containing 21% oxygen and 79% nitrogen (the breathable air
must be in compliance with EN 12021.) Fill your air cylinders
only from certified compressors. If you have any doubt
concerning the quality of the air (e.g. smell) DO NOT DIVE.
The addition of helium or other substances, or using different
mixtures may cause deterioration or corrosion of metal and
rubber parts. Such deterioration may lead to premature aging
or failure. Non-standard air mixtures may also increase the
risk of fire or explosion.
• When storing, transporting in your car, or shipping the BCJ,
do not have the inflator hose folded. Also, do not pull on the
inflator section when taking the BCJ out from a mesh bag
or the like or when carrying it around. Applying excess force
to the inflator hose, for example by folding it, twisting it, or
pulling on it too hard, can cause cracks in the hose.
• Never leave the BCJ in the passenger compartment or
trunk of your car on a clear day, exposed to direct sunlight
on a boat, or in any location that may reach extremely high
temperatures over 60°C. The heat and UV rays can cause
deformation and discoloration and reduce the service life of
the material the BCJ is made from.
• Keep the BCJ away from knives, cutters, and other sharp
pointed objects.
• When handling the BCJ, never place any heavy objects on it,
drag it around, or handle it roughly in any way.
ASSEMBLY
Airway systems are standard on all TUSA BCJ.
Low pressure quick disconnect (QD) hose installation.
* LP hoses and the pneumatic inflation valve operating
pressure is 10 psi - 174 psi (0.7 bar – 12 bar).
Connecting to your regulator
Screw the threaded end of the QD hose into the low pressure
port of the regulator BY HAND. Tighten gently but firmly with a
15 mm spanner. The threaded connection of the QD hose to
the pressure reducer is a standardized 3/8" UNF connection.
Please refer to the user manual of your regulator to identify
the LP outlets.
Check your system before diving: The low pressure gauge
connected to LP Ports must not read over 1.2 MPa (12 bar,) or
under 0.8 MPa (8 bar) if the tank is full.
It is recommended that your TUSA dealer installs the QD hose
on your regulator.
WARNING:
Do not connect the QD hose to the regulator high
pressure (HP) port. Otherwise this may cause injury or
equipment damage.
Connecting to Your BCJ
Connect the QD hose inflator by pulling the quick-disconnect
collar back with your thumb and forefinger, while pushing the
hose coupling onto the inflator plug. Release the collar when
the coupling is fully engaged. Pull gently but firmly on the hose
to check that the coupling is securely joined to the plug. To
disconnect the inflation hose from the inflator, pull the quick-
disconnect collar back and disengage the coupling from the
plug. [Fig. 1] Secure the airway together with the QD hose to
the hook and loop hose retainer. [Fig. 2]
Setting Up the Low Pressure Hose (APA type)
Connect the coupler plug of the low pressure hose to the APA,
then fit the low pressure hose into the groove on the side of
the inflator hose. This keeps the hose neat, makes it easier
to handle, and makes it easier to mount and remove the BCJ.
[Fig. 3]
Inflator Setting Position (APA type)
The recommended APA inflator setting position is the same as
for a regular inflator. [Fig. 4] It is possible to perform normal
deflation and use rapid exhaust deflation by pulling the APA
inflator main unit. When primarily using the rapid exhaust
function with the APA deflation button, there is an APA inflator
setting position that uses the BCJ hose holder to secure the
APA deflation button at hand. [Fig. 5]
DEFLATING THE BCJ
Rapid Exhaust Deflation
The rapid exhaust feature is standard on TUSA BCJ. It allows
the diver to vent air rapidly from the BCJ. Pull gently on
the forward inflator assembly to activate the exhaust valve.
Maintain forward pressure until enough air has been expelled
to reach the desired buoyancy. [Fig. 6] Release pressure to
close the valve.

IMPORTANT NOTICE :

• The deflation device with the maximum outflow of air is the
shoulder dump valve [Fig. 7] or rapid exhaust valve [Fig. 6]
• The rapid exhaust valve has a pull travel limited to
approximately 6 mm (1/4"). Pulling harder WILL NOT
increase air flow. Do not forcefully yank or jerk the inflator
assembly to activate the valve. Otherwise this may cause part
damage and system malfunction.
• Should the rapid exhaust valve not operate properly, manual
(oral) deflation can be accomplished using the
deflation button.
