using this product. Ifyou do not completely understand these instructions,
do not use this BCD.
Do not use this BCD if you have not received proper training
and certification in SCUBA diving.
The BCD is intended as a buoyancy compensator only and it could not
be consider as a “Life buoys and lift jacket. This is not a life jacket; it does
not guarantee a head up position of the wearer at the surface.
This isnot a life jacket; itdoes not guarantee a head up position of the
wearer at the surface.
Emergency face up flotation may not be provided for all wearers and in all
conditions. Improper use, or intentional misuse of this product may cause
serious injury or death. Do not inhale gases from within this BCD.

6
Prior to each dive, full inflate the BCD and inspect for leakage, damage
and proper operation.
Before diving this BCD in open water, it is important to familiarize yourself
with it first in confined shallow water, do not enter open water until you
have weighted yourself properly and become familiar with using all of its
features and adjustments.
Before entering water, check to ensure that you can ditch the dumpable
weight pouch quickly and easily without any obstruction. You may need to
do it when under water in the events of out of air emergency or
uncontrolled descent.
Obtain prescribed service for this BCD from an IST dealer at least once a
year. The service consists of a complete overhaul of the power inflator
and a general air leak inspection of valve connections and bladder.

7
Repair and disassembly must only be performed by IST dealers.
Unauthorized service will void the warranty and may cause this product
to malfunction.
The Maximum depth covered by certification is 50 meters.
Limitation to use of compressed air in compliance with EN12021
Maximum recommended cylinder capacity is 20 liters (See Fig. 1)
Temperature Range for Use:
Air -20℃to +50℃
Water -2℃to +40℃
Abuoyancy compensator is not a breathing
system and that gas should not be inhaled
from the buoyancy compensator's bladder.

Airway
Power inflator
Note:
Oral inflation of your BCD under water is a skill that
must be achieved under the supervision of
a certified diving instructor.
Note:
Depressing the oral inflator button while the BCD is
empty may allow the water to enter the bladder.
Inflator’s Working Pressures are 110 psi (7.58bars)
Minimum, 160 psi (11.03bars) Maximum, and 140 psi
(9.65bars) nominal.
Inflator button, Press it to inflator BCD. (See Fig. 1-1)
Manual button and Mouthpiece, press it to deflate BC
or oral inflate BCD (See Fig. 2)

Rapid Exhaust Valve
It automatically release air when the air pressure inside the bladder is
nearly 2.4 pounds per square inch (0.165bar) over ambient.
You can pull to dump air thru REV too. (See Fig. 3)

Attaching Low Pressure inflator hose
Ensure the presence of an O-ring. (See Fig. 4)
Screw the male end into the LP port of regulator, make sure it secured.
(See Fig. 5)
Attach female end onto inflator nipple. (See Fig. 6)
Warning:
Only attach the LP hose to the lower pressure (LP) port of
regulator. Attach to the High Pressure (HP) port may cause the
hose to burst and result in serious injury.

Note:
Wet the tank band first, the nylon webbing stretches a little while wet.
Note:
Make sure the metal loop of the tank band is as close to the rear of
BCD as possible, this will provide a great range of adjustment.
Loop the tank locator strap over the tank valve; adjust it to hold the BCD
at the desired height position. (See Fig. 14)

Close the sternum and waist straps, if equipped, and pull the free ends until
they are comfortably snug but not restricting (See Fig.24&25)

Over Pressure Relief Valves
Some BCD models have this feature.
It automatically release air when the air pressure inside the bladder is nearly
2.4 psi (0.165bar) over ambient.(See Fig. 26)
You can pull the ball to rapidly dump the air too.(See Fig. 27 & Fig. 28)
The maximum outflow relief valve is the dump valve which assembly at
the bottom or top of BC. (See Fig. 26)
Note:
Whenever you remove and replace the cap of the valve, make sure
that the stainless spring is in correct place; pull it to feel the spring
function well and inflate the BCD to see if it is secured and no leak.
