SAFETY INFORMATION
General Precautions & Warnings
Before using this buoyancy compensator (BC), you must receive instruction
and certification in SCUBA diving and buoyancy control from a recognized
training agency. Use of SCUBA equipment by uncertified or untrained
persons is dangerous and can result in injury or death.
Read this owner’s manual completely before attempting to use your BC, and
become familiar with it first in a controlled environment such as a swimming
pool, in order to weight yourself properly and to become comfortable with
using its many features and adjustments.
Before every dive, 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 BC is not functioning properly or is damaged, remove it from
service until it can be repaired by an authorized Aqua Lung® Dealer.
Your BC is not a lift bag. DO NOT use it to bring heavy objects to the surface.
Doing so may cause permanent damage to the BC, and could also result in
serious injury or death due to embolism or decompression sickness.
In an emergency such as an out of air situation or uncontrolled descent, it
is important to remove and jettison weight immediately. DO NOT depend
solely on using your BC’s power inflator to lift you to the surface.
In the event of an uncontrolled, rapid ascent, it is important to immediately
begin venting air from the BC. Continue venting air to slow your ascent rate
if neutral buoyancy cannot be reestablished.
DO NOT inhale from your oral inflator. The BC may contain harmful
contaminants or gasses, which could cause suffocation or injury.
Factory prescribed service for this BC must be performed at least once
annually by a factory trained technician who is employed by an authorized
Aqua Lung® Dealer. Annual service consists of a complete overhaul of the
power inflator, and a general air leak inspection of the bladder and valve
connections.
Disassembly, repair, or lubrication must not be attempted by persons who are
not factory trained and authorized by Aqua Lung. Unauthorized service will
render the warranty null and void.
This BC is designed for use with compressed air or Nitrox/EAN (enriched air
nitrox) mixtures not exceeding 40% oxygen. Any use of gas mixtures with
increased oxygen content or the addition of helium or other substances may
cause corrosion, deterioration and/or premature aging of the BC 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
BC resulting in injury or death. Non-standard breathing mixtures may also
present a risk of fire or explosion. The use of Nitrox/EAN requires additional
training. Failure to observe this warning may result in injury or death. Use
only nitrogen/oxygen mixtures containing no more than 40% oxygen.
Pearl i3 BC Owner’s Manual
WARNING: A buoyancy compensator (BC) is NOT a life jacket! It is
not designed to provide face-up flotation in all situations; therefore
it does not meet U.S. Coast Guard regulations for a life preserver or
personal flotation device (PFD). If you become unconscious in the
water without a buddy present to immediately give assistance, you
may suffer serious injury or death from drowning.
Your buoyancy compensator is primarily designed to help you maintain
neutral buoyancy while in a comfortably balanced, face-down swimming
position underwater. It is also designed to provide you with flotation so
that you can rest on the surface, but it is not designed to function as a
life preserver or personal flotation device (PFD). In order to meet U.S.
Coast Guard regulations, a PFD must be designed so that it automatically
rights you to a face-up position and holds your head out of the water on
the surface. The design characteristics of a personal flotation device
are different from those of a buoyancy compensator. The ability of any
flotation device to float you in a face-up position can also be affected by
other diving equipment you wear, including a cylinder, weight or exposure
suit, and whether it can be inflated before you lose consciousness.
For this reason, it is important to always dive with a buddy, and maintain
close proximity with them at all times. Do not depend on any flotation
device to hold your face above the surface in the event that you are
rendered unconscious in the water while diving.
WARNING: Although this manual provides some basic guidelines for
certain buoyancy control techniques, it is not a substitute for training from a professional diving instructor. Failure to weight yourself
properly may create a hazardous condition that could lead to serious
injury or death. If you are unsure how to weight yourself in order to
achieve optimum buoyancy underwater and on the surface, do not
dive until you have obtained the necessary instruction from your diving instructor or an authorized Aqua Lung ® Dealer.
If you have any questions regarding your Buoyancy Compensator
or these instructions, contact your local dealer or Aqua Lung at:
(760) 597-5000
Pearl i3 BC Owner’s Manual
Note: The terms “hook”, “loop” and “hook & loop” are used throughout this
manual. Hook & Loop is commonly known as Velcro®, which is a trademarked brand of hook & loop. Many of the BC’s components have hook &
loop attachments, including the waistband, cylinder bands, and weight pouch
flaps.
BASIC SETUP
Aqua Lung recommends that you bring your buoyancy compensator,
together with your regulator, to your authorized dealer for the installation of
the MP inflator hose and other accessories. The retailer can also answer
any questions you may have pertaining to the information in this manual.
If it is not possible to return the BC with your regulator to your authorized
dealer, you may install the MP quick disconnect inflator hose by carefully
performing the steps in the following procedure.
WARNING: DO NOT connect the inflator hose to a high pressure (HP)
port (greater than 200 psi / 14 bar). This may cause the hose to burst
when pressurized, which can result in serious injury. If you are unsure which regulator port is medium pressure (MP) or high pressure
(HP), consult your regulator owner’s manual or your dealer before
attaching the hose.
Attaching the MP Hose to the First Stage
1. Remove the inflator hose from the i3.
2. Remove the port plug
from a MP port on the regulator using an appropriately sized wrench.
3. Check to ensure the o-ring is
present and in good condition,
and screw the threaded end of
the hose into the port. Tighten
to 40 in/lbs (4.5 Nm) with a 9/16"
wrench.
Pearl i3 BC Owner’s Manual
Securing the BC to the Cylinder
Note: BC cylinder bands adjust for all standard cylinder diameters: 6.9"
(17.5 cm), 7.25" (18.5 cm), and 8.0" (20.3 cm). The cylinder bands are properly threaded to the buckles when the BC leaves the factory. If rethreading is necessary, follow the procedure in the next section: Threading the
Cylinder Band.
1. Remove the free end of the cylinder band from outer slot on the
buckle.
2. Wet the cylinder band and then slide it over the cylinder so
that the BC is at the desired position in relation to the cylinder
valve. Make sure the cylinder valve air outlet is facing the back
of the BC.
3. While holding the cylinder secure,
pull the free end of the cylinder band
until there is a very tight fit between the
pack and the cylinder.
4. Close the buckle halfway to
hold the cylinder band taut, and
thread the free end of the band
through the open slot in the end
of the buckle.
5. Pull the cam buckle closed so that it lies flat against the cylinder. Secure the end of the cylinder band with the hook & loop
attachment.
6. Test the tightness by pushing/pulling the back frame and
cradle.
Pearl i3 BC Owner’s Manual
WARNING: The cylinder band will initially stretch as it becomes
wet. Always wet the band before making the final adjustment; apply
enough tension to ensure that the cylinder is completely secure. Test
this connection before every dive. If the cylinder slips free from the
BC during the dive, you may lose your air supply, which could lead
to serious injury or death.
TOP VIEW
Threading the Cylinder Band
Step 1: Firmly grasp the metal
D-ring with your left hand.
Step 2: While firmly holding the
metal D-ring, rotate the buckle
back towards the webbing. The
buckle should form an angle with
the metal D-ring as shown in the
top view.
Step 3: Insert band through
the metal D-ring, then through
the middle slot.
Step 4: Insert band
through the inside slot.
Step 5: Insert band
through the outer slot.
Pearl i3 BC Owner’s Manual
NOTE: This final threading step is done when the BC is secured to the cylinder (refer to step 4, p. 7). Close the buckle halfway to prevent the webbing
from slipping and thread the free end of the band through the open slot in
the end of the buckle.
Double Cylinder Setup
Aqua Lung does not offer a twin cylinder kit for the Pearl i3. If you
want to adapt twin cylinders to the Pearl i3, you must consult with your
professional dive retailer about third-party twin band kits that would work
with the Pearl i3.
Before adapting your BC for use with double cylinders, it is important to
compare the lift capacity of your particular BC size and model with the
buoyancy specifications of the cylinders, the amount of weight you will
carry, and the type of exposure suit you will wear. When fully charged and
worn together as doubles, some cylinders may create enough negative
buoyancy to counteract the amount of lift your BC can provide. At depth,
this can lead to a dangerous situation if your wetsuit becomes compressed
and you can no longer achieve positive buoyancy by jettisoning weight.
WARNING: The use of oversized twin set ups can lead to a dangerous situation underwater, including your inability to achieve positive
buoyancy, or structural failure of the backpack. Such an event while
diving may separate you from your primary air source, and could lead
to serious injury or death.

Pearl i3 BC Owner’s Manual
Adjusting the Fit
The Pearl i3 has two adjustments that allow you to customize the fit: the
position of the shoulder buckles and the length of the cummerbund. The
procedures for making these adjustments are outlined below. It is important to take into account the exposure suit you will be wearing when
making adjustments. For example, if you adjust the Pearl i3 to fit over a
T-shirt or bathing suit, it will be too small when you put it on while wearing
a 7mm wetsuit or a drysuit.
Adjusting the Shoulder Buckle Position
For optimum comfort, the shoulder buckles can be raised or lowered. This
also allows you to extend or reduce the length of the shoulder straps.
1. Remove the free end of the upper torso strap that is tucked away
between the bladder and shoulder
lobe (Figure 1).
Figure 1
2. To lower the buckle, tilt the buckle inward and pull straight down
(Figure 2); to raise the buckle, hold
the buckle with one hand on pull on
the free end of strap (Figure 3).
Figure 2
3. Repeat steps 1 & 2 for the other
buckle.
4. After each adjustment, try the
BC on to make sure it fits properly.
5. Once the BC is properly adjusted, tuck the free ends of the straps
between the bladder and shoulder
lobes.

Adjusting the Cummerbund Length
The Pearl i3 has a two-part cummerbund. Each part of the cummerbund
is secured to the backside of the back pad with a specially designed
retaining pin. The length of the cummerbund is changed by inserting the
retaining pin into one of three available channels on the cummerbund.
Follow the steps listed below to change the cummerbund length:
1. Disconnect the shoulder buckles, waist buckle and cummerbund. Lay out the BC with the backpad facing upward.
2. Fold up the lower edge
(kidney area) of the backpad
to expose the retaining pin
Retaining pin
(Figure 4).

4. Slide the cummerbund off
the retaining pin (Figure 6).
Insert the retaining pin into
one of the other channels to
lengthen or shorten the cummerbund (Figure 7).
Figure 6
5. Resecure the retaining clip
by snapping it back onto the
end of the retaining pin.

Routing & Attaching the MP Inflator Hose
1. After attaching the BC and regulator to a cylinder, make sure the bladder is completely deflated (see Deflation Methods, p. 22.)
2. Route the MP hose down
the back of the BC along the
cylinder and through the hook
& loop hold-down. If needed,
adjust the hook & loop holddown to the desired size.
3. Remove the dust cap on
the quick disconnect plug
on the i3 control unit.
NOTE: The dust cap can be stored in the small pocket below the control
unit. Be sure to keep the dust cap on while not in use.
4. Grab the hose grip between
your thumb and forefinger, then
slide the sleeve back.
Pearl i3 BC Owner’s Manual

5. Place the fitting over the quick disconnect plug and firmly push inward while
releasing the hose grip. Check to ensure
the hose is securely attached.
6. To test the connection, slowly open the cylinder valve and pressurize
the regulator. Lift up on the lever and listen for the flow of air into the BC
bladder.
NOTE: The Pearl i3 is equipped with a longer than normal MP inflator hose.
It is very important to use the inflator hose provided with the BC (if the hose
is too short it will not reach the i3 control unit.)
Hose lengths are as follows:
XS/S – 27 inches (pn 24827 — red)
M/ML/L – 33 inches (pn 24833 — light blue)

Pearl i3 BC Owner’s Manual
WEIGHT INTEGRATION FEATURES
The Pearl i3 features the SureLock™ (SL) weight system. With the SureLock™ system, weight pouches are secured with a mechanical locking
mechanism, as opposed to a hook & loop attachment used on other
models. The SureLock™ weight system either supplements or replaces a
conventional weight belt. This unique feature allows you to quickly jettison
either one or both of two weight pouches in the event of an emergency,
thereby maintaining better control over your rate of ascent. The weight
pouches can be easily reloaded into their respective holsters while you
are wearing the BC. This makes the BC much easier to don than other
weight-integrated BCs that must be fully loaded with weight prior to donning.
It is very important to read the following instructions, and become thoroughly familiar with the correct methods for installing and releasing weight
before you dive with your BC.
Weight System - Setup & Installation
The weight system features two interchangeable weight pouches which
can be filled with either block weights or “soft weight” (pouches containing
lead shot), in increments of 5 pounds or less. For ease of operation, lowprofile block weight is strongly recommended. Each weight pouch can
hold a maximum of 10 lbs/4.5 kg (20 lbs/9 kg total).
Loading the Weight Pouches
Aqua Lung recommends that each pouch is loaded with equal amounts of
weight for optimum balance; this will prevent the tendency to roll to one side
during the dive. Also, it is strongly recommended that each weight pouch
is fully loaded with two separate weight blocks for the standard pouch.
For example, if you want to load a standard pouch with 6 pounds, use two
separate 3 pound weights.
1. If the weight pouches are installed in the BC, remove them by firmly
pulling the release handle toward the center of the waistband (see p. 17,
Releasing Weight Pouches).
2. Lift up each pouch’s flap (Fig 1a), and lay it back over the handle (Fig
1b). While holding the pouch fully open, insert the weight and then close
the flap. When each pouch has been loaded with weight, firmly run your
hand over the flaps to securely fasten the hook & loop (Fig 1c).

Surelock™ Weight Pouch Installation
CAUTION: Aqua Lung strongly recommends that you do not attempt to don
your BC when it is fully loaded with weight. You may otherwise risk injury
due to muscle strain or a temporary loss of balance.
The pouches are installed with the smooth panel facing outward (pouch
flap facing toward the BC).
To install either pouch, grasp the D-ring or lobe in front of the female
SureLock™ receptacle with your opposite hand and slide the closed end
of the pouch into the opening of the holster. Insert the male portion of the
SureLock™ buckle (a) into the female receptacle (b) on the BC until you
can hear/feel it click into place.

a
WARNING: Before every dive, it is important to make sure each
weight pouch is secure, in order to prevent the pouches from falling
out. Involuntary release of both weight pouches underwater can
cause a sudden increase in buoyancy causing a rapid ascent, which
could lead to serious injury or death due to arterial gas embolism,
decompression sickness, or drowning.
16
Pearl i3 BC Owner’s Manual
Releasing Weight Pouches
Unlike a weight belt, which has only one release mechanism, each weight
pouch is connected to the BC independently of the other and must be
released separately. This provides you with the option of being able to
jettison one pouch at a time, thereby maintaining better control of your
ascent rate in an emergency.
In the event that you need to jettison weight, simply pull the release
handle of each pouch towards the center of the waist buckle. When the
pouch is completely disengaged from its holster, hold it out and away from
your body before dropping it.
WARNING: Ensure that your weight pouches are not obstructed by
any straps, lines, etc. DO NOT add weight to the BC’s pockets, as
this may interfere with the removal of the pouches in an emergency.
Failure to ditch weight in an emergency may lead to serious injury or
death due to drowning.
WARNING: To avoid injuring other divers, always look below you before dropping weight.
Note: In addition to becoming familiar with the weight system yourself, it is
very important to explain its function to your dive buddy so that he/she is
equally familiar with it.
Pearl i3 BC Owner’s Manual
17
Non-releasable Weight
To supplement the releasable weight, the Pearl i3 is designed to carry
non-releaseable weights in two fixed pockets located on the cylinder band.
For sizes S-L, each pocket can hold up to 5 lbs (10 lbs/4.6 kg total).
To install weight into the non-releasable weight pockets, simply disconnect the flap buckle, slide in the weight block, fold the flap over the pocket,
and reconnect the buckle.
The non-releasable weight pockets are designed to hold single rectangular weight blocks. Aqua Lung strongly advises against using small bulletshaped weights and shot weight.
NOTE: Aqua Lung recommends that the non-releasable pockets be loaded
with equal amounts of weight for optimum balance. This will prevent the
tendency to roll to one side during a dive.
WARNING: Because the weight is non-releasable, it must not be used
as your primary source of ballast. A large percentage of your weight
should be in the releasable weight pouches. This will enable you to
achieve positive buoyancy by ditching the weight pouches in the
event of an emergency.
WARNING: The non-releasable weight pockets are intended strictly
for containing non-releasable weight, used in addition to releasable
weight. Do not fill either pocket with weight unless you are certain
you can achieve positive buoyancy at depth by releasing your weight
pouches or weight belt while your BC is completely deflated.
18
Pearl i3 BC Owner’s Manual
DONNING & ADJUSTMENT PROCEDURES
1. Remove the weight pouches from the BC.
2. L
oosen and disconnect the waist buckle and cummerbund.
3. Ensure that the buckles on both torso straps are securely fastened.
While firmly holding the torso strap where it connects to the BC lobe,
fully extend each torso strap to its maximum length by pushing straight
up on the slide buckle.
4. While your dive buddy lifts and holds the BC/cylinder behind you,
place your arms through the BC torso straps as if you were putting on
a jacket.
5. W
hile your buddy continues to hold the cylinder, secure the cummerbund around your waist (not hips). The best positioning of the cummerbund is between the hips and rib cage. The weight of the cylinder
should rest on the lumbar region (lower part) of your back. The tensioning bands should be fully extended when fastening the cummerbund
at the surface.
NOTE: The Pearl i3 cummerbund has a heavy-duty elastic tensioning
band that allows the cummerbund to compensate for suit compression
while at depth.
6. A
fter the cummerbund is adjusted, connect the waist buckle and pull
the adjustment straps until lightly snug.
7. A
fter your buddy has released the cylinder and the BC feels comfortably supported on your hips and shoulders, bend forward at the waist
and adjust the torso straps to a comfortable length by pulling on the
torso strap D-rings.
8. If necessary, readjust the cummerbund so that is comfortably snug, but
not restricting. The cummerbund should have an overlap of at least 4
inches (10 cm); any excess can be tucked under the BC.
NOTE: Adjusting the shoulder straps too tightly will transfer the cylinder
weight from the hips to the shoulders, restricting your arm movement and
decreasing comfort.

INFLATION METHODS
Oral Inflation
The oral inflation tube is located
under the flap/hook & loop on the
left shoulder of the BC.
To orally inflate your BC, pull
down on the mouthpiece to
fully extend the oral inflation
tube so that there are no
kinks in the tube.
Push the mouthpiece against your lips and exhale into the mouthpiece.
Immediately after exhaling, move the mouthpiece away from your lips to
keep the air from escaping the BC.
20
Pearl i3 BC Owner’s Manual
Storing Oral Inflator
When the oral inflator is not in use, fold the tube and store it under the
flap/hook & loop using the following method.
Using your index finger as a guide, begin
folding the oral inflator hose, bending
once under the pouch.
Continue by folding hose
again, using your index
finger as a guide.
Hose should fit evenly and flat
in pouch under the flap/hook
& loop.
Pearl i3 BC Owner’s Manual
21
Secure the oral inflator snugly with
the flap/hook & loop.
WARNING: Incorrect oral inflator storage could result in a failure to
deploy.
Power Inflation with the i3 Control Unit
For the power inflator to operate, the MP inflator hose must be connected
(see “Routing and Attaching the MP Inflator Hose”, p. 12). After the hose
is attached to the i3 Control Unit, pressurize the first stage regulator by
slowly opening the cylinder valve.
To inflate your BC with air, lift up on the lever of the i3 Control Unit. Do
not hold the lever up continuously underwater, as this could cause you to
become excessively buoyant. Instead, inflate the BC in short bursts until
you become neutrally buoyant.

22
Pearl i3 BC Owner’s Manual
WARNING: Do not rely on the i3 Control Unit as the only means to
inflate your BC. It is important to practice the technique for orally
inflating your BC so that you are prepared for any type of malfunction
or out of air situation that could render the i3 Control Unit inoperable.
You may otherwise be unable to achieve positive buoyancy in an
emergency, which could lead to serious injury or death.
DEFLATION METHODS
Throughout the course of a dive, it will be necessary to release air from the
BC using one of the two methods described in the following instructions.
Deflation via i3 Control Unit
To deflate your BC, simply press down on the lever of the i3 Control Unit
(see Power Inflation with the i3 Control Unit photo on the previous
page). This will open both of the Flat E-Valves simultaneously to allow air
to escape the BC regardless of your body position. Deflate the BC in short
bursts until you become neutrally buoyant.
WARNING: Avoid using excessive torque when pressing the lever of
the i3 Control Unit.
Deflation via Flat E-Valve (right shoulder)
The Pearl i3 is equipped with Flat
E-Valve Technology. To deflate the
BC, manually pull on the knob and
cord assembly located on the right
front shoulder to quickly dump air.
Flat E-Valve
Pull Knob
Pearl i3 BC Owner’s Manual
23
Overpressure Relief (OPR) via Flat E-Valve
In addition to the Flat E-Valve on the right
shoulder, the Pearl i3 has a second Flat EValve on the back lower right of the BC.
Lower E-Valve
Both Flat E-Valves function as overpressure relief valves to relieve excess pressure inside the bladder.
NOTE: One-way valves are included in Flat E-Valve Technology. This allows air to escape the BC yet does not allow water to enter while venting.
CAUTION: The proper function of the overpressure relief valve is vital to
prevent damage to the BC bladder. Unauthorized service or tampering
may render these valves inoperable, and could cause the bladder to leak
or burst. This type of damage is not repairable, and is not covered under
warranty.
WARNING: Most training agencies recommend that you descend
in an upright, feet-first position, in order to maintain a slower and
more controlled descent. This is especially true if you experience
difficulty equalizing your ears, or if you are descending in low
visibility conditions.
SPECIAL FEATURES
Retractor Mount
On the lower front left pocket is a
grommet hole for an optional retractor available from Deep See (pn
D745034). Installation instructions are
included with the retractor.

the knife, refer to the instructions that
come with the knife.
.
CAUTION:
When replacing the knife into its sheath, be careful not to
puncture the bladder.
Octo Pocket™
The Pearl i3 features an Octo Pocket™ which allows you to easily place
your octopus (alternate air source) in a
highly visible, easy to access location.
Fold the hose back on itself and insert
downward into the pocket.
Hideaway Pocket
The Pearl i3 features a hideaway
pocket on the left side of the BC,
located under the i3 Control Unit. To
deploy, simply pull down on the release tab. To store, roll up the pocket,
and secure using the hook and loop
attachments.

Pearl i3 BC Owner’s Manual
PREDIVE 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. C
onnect the i3 Control Unit to a source of clean compressed air via the
MP quick disconnect hose. Lift up and release the lever intermittently
to ensure that the airflow is unobstructed, and that the airflow stops
completely when the lever is released. Push down on the lever to make
sure the BC is venting air.
2. Manually operate the Flat E-Valve by pulling on the attached knob and
cord to release air from inside the BC, and then fully inflate the BC
until the Flat E-Valve opens. Examine the operation of the Flat E-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.
WARNING: If you can hear any leaks, or if the bladder begins to
deflate within 5-10 minutes, DO NOT attempt to use the BC until it
has received service from an authorized dealer.
4. F
ully inflate the BC once again, and disconnect the i3 Control Unit from
the compressed air supply and listen closely for any leaks.
5. Check both weight pouches to ensure that they are correctly fastened
to the BC prior to entering the water.
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.

POSTDIVE CARE & MAINTENANCE
With proper care, your BC will provide many years of reliable service. The
following preventive maintenance must be performed to extend the life of
your BC:
1. A
void prolonged exposure to direct sunlight and extreme heat.
Nylon fabric can quickly fade when exposed to the sun’s ultraviolet
rays, and extreme heat may damage the welded bladder seams.
2. Avoid repeated or prolonged use in heavily chlorinated water, which
can cause the BC fabric to discolor and decay prematurely.
3. Do not allow the BC to chafe against any sharp objects or rough
surfaces that could abrade or puncture the bladder. Do not set or
drop heavy objects such as block weights on the BC.
4. Avoid any contact with oil, gasoline, aerosols, or chemical solvents.
5. To preserve the life of the bladder, rinse it inside and out with fresh
water after every day of use, using the following procedure:
a) Pressurize the i3 Control Unit with MP air via the MP hose.
b) Using a garden hose, direct water through the multiport to
flush the interior of the bladder, and then thoroughly rinse the
exterior of the BC.
CAUTION: Before rinsing, ensure that the i3 Control Unit is pressurized
with air. This will prevent debris and contaminants from entering the valve
mechanism if the lever is accidentally lifted.
c) C
ompletely drain the bladder of water, either through the Flat
E-Valves or the multiport.
d) Inflate the BC, and allow it to dry inside and out. Store the BC
partially inflated, away from direct sunlight, and in a clean, dry
area. Do not store the BC in an enclosed space, such as a car
trunk, where temperatures may fall below 0ºF (-18ºC) or rise
above 120ºF (49ºC).

DEALER INSPECTION & SERVICE
WARNING: DO NOT attempt to perform any disassembly or service of
your BC. Service requiring disassembly must only be performed by
a factory-trained Aqua Lung ® technician. To obtain service or repair,
such as power inflator service or replacement of the bladder, see your
local authorized dealer.
1. It cannot be assumed that the BC is in good working order on the basis
that it has received little use since it was last serviced. Remember that
prolonged or improper storage can still result in internal corrosion and/
or deterioration of o-ring seals and valve springs, as well as bladder
seam degradation.
2. It is imperative that you obtain prescribed dealer service for your
BC at least once a year from an authorized dealer, including
a general air leak inspection and complete overhaul of the i3
Control Unit and Flat E-Valve. Your BC may require this service
more frequently, depending on the amount of use it receives and the
environmental conditions it is used in.
3. If the BC is used for rental or training purposes in salt, chlorinated,
or silted fresh water, it will require prescribed dealer service every
three to six months. Use in chlorinated water will greatly accelerate
the deterioration of most components, and require more frequent
service.
4. DO NOT attempt to perform any disassembly or overhaul service of
your BC. Doing so may cause the BC to dangerously malfunction, and
will render the warranty null and void. All service must be performed
by an authorized Aqua Lung® Dealer.
IT IS IMPORTANT TO OBTAIN PRESCRIBED DEALER SERVICE
FOR YOUR BC AT LEAST ONCE ANNUALLY, FROM AN
AUTHORIZED AQUA LUNG® DEALER. YOUR PERSONAL SAFETY
AND THE MECHANICAL INTEGRITY OF YOUR BC DEPEND ON
IT.

Limited Lifetime Warranty
Warranty coverage on buoyancy compensators covers the product throughout its useful life, subject to the
conditions listed below and utilizes a pro-rated replacement policy*.
Aqua Lung America warrants to the original purchaser for the useful life of the product, from the date of purchase,
that the product will be free from defects in materials and workmanship, provided that it receives normal use,
proper care and prescribed dealer service subject to the limitations listed below. The Limited Lifetime Warranty
is extended only to the original purchaser for purchases made from an Authorized Aqua Lung America Dealer and
is not transferable. This warranty is limited to repair or replacement only at the discretion of Aqua Lung America.
Limitations
Warranty coverage does not extend to damages caused by improper use, improper maintenance, neglect, unauthorized repairs, modifications, accidents, fire, casualty or normal wear and aging.
Cosmetic damage(s), such as scratches, nicks and fraying are not covered under warranty except when
the product is new, out of the original packaging.
This warranty does not extend to equipment used for rental, commercial or military purposes.
This warranty covers products purchased in the USA. For warranties that may apply elsewhere, please
contact your local representative.
*Product Replacement on a Prorated Basis
Products under the Limited Lifetime Warranty that malfunction due to material or manufacturer defects that
have also had a significant amount of use will be replaced on a prorated basis. Prorating will be determined
by a percentage factor based on the condition of the product and how long the product was used prior to
the warranty claim. This can be useful to evaluate Limited Lifetime Warranty claims since the warranty
period is for the “useful life of the product” and not a set length of time. The following guidelines should be
used in determining what prorated percentage will be used.
Note: This can be a subjective evaluation. Fair and reasonable judgment should be used.
