WARNING
DYNAMICNORD rejects any responsibility for damages caused by
non-compliance with the instructions in this manual.
Important cautions
For your protection, please note the following when using the
DYNAMICNORD BCD:
Use the equipment in accordance with the instructions described
in this manual and only after fully reading and understanding all
instructions and warnings.
The equipment may only be used for the purposes described in
this manual.
Compressed gas cylinders may only be filled with atmospheric
compressed air in accordance with standard EN 12021. In
addition to cylinder corrosion, moisture building up in the
compressed gas cylinders could cause icing and regulator
malfunction during cold water dives. The compressed gas
cylinders must be transported in accordance with the local
laws regarding the transport of dangerous goods. The use of
compressed gas cylinders is subject to the laws governing the
use of gases and compressed air.
The equipment must be serviced by qualified professionals at
the prescribed intervals. Repairs and maintenance work must be
carried out by an authorized DYNAMICNORD dealer using original
spare parts by DYNAMICNORD only.
If the equipment is not used in accordance with the purpose
expressly approved by DYNAMICNORD in this manual, or if
repairs or service work are carried out by untrained personnel or
personnel not certified by DYNAMICNORD, liability for the correct
and safe functioning of the equipment shall pass fully to the
owner/user.
The content of this manual is based on the latest information
available at the time of printing. DYNAMICNORD reserves the
right to make changes at any time.
All dives must be planned and conducted in such a way that
at the end of the dive there is enough air left in the cylinder for
emergencies. Generally, a reserve of 50 bar is recommended.
Always perform the required pre- and post-dive checks of
your BCD.

ENGLISH
General information
Defined purpose of the BCD – intended use
A BCD is designed to allow the diver to establish hydrostatic balance
during the dive. This means that a state of levitation can be achieved
at any depth.
This is when you are neither descending nor ascending.
The SBC-20 model is approved for use with mono cylinders with a
maximum volume of 15 liters or a maximum total weight of 20 kg.
Preparation
Low pressure hose
Ask your dealer to connect the inflator’s low pressure hose to an
available low pressure port on the first stage of your regulator.
Standard tank strap
The standard tank strap allows you to quickly detach a single device
from the BCD. It must be attached as follows.
Rotate the latch until it snaps into place in the open position. Slide
the strap through the center slot into the plastic buckle as shown
(fig. A).
DYNAMICNORD BCDs have a hard carrying frame. Please align
the indentation of the carrying frame with the upper curve of the
tank (1), place the safety loop (2) around the valve (fig. B) and set
the correct length (fig. C).
This way, the safety loop attached to the top of the frame prevents
the BCD from slipping down while the strap is being attached and
closed. Once set correctly, the correct position is always quick and
easy to find again when attaching the BCD to the tank.
Feed the strap back through the first slot (fig. D) and tighten it.
Tilt the clasp slightly so that the strap can no longer slip. Then
feed the free end of the strap through the third slot (fig. E).
Close the latch (fig. F). If the strap is too tight or too loose, open
the latch to adjust the length. We generally recommend lifting the
fully assembled diving equipment – consisting of cylinder, BCD
and regulator – by the cyclinder valve.
Shake the unit on the BCD to ensure that the tank is securely
attached.
WARNING
Never use your BCD as an aid or as a lift bag to transport ob-
jects to the surface. These objects can be lost during ascent,
causing a sudden increase in buoyancy and loss of buoyancy
control.

ENGLISH
To prevent an accidental loss of the tank, ensure that the
strap is wrapped tight enough around the tank so that it
cannot move or slip on the BCD. Failure to follow these
instructions can result in injury or death.
Soak the fabric of the tank strap and tighten it rmly before
each use of the BCD. The fabric might stretch when it comes
into contact with water. If the fabric is not soaked, the tank
strap might become too loose around the SCUBA cylinder.
This can result in injury or death.
Before each dive, check that the tank strap is positioned
correctly and ts tightly.

ENGLISH
Weight belt
Total weight must be calculated and tested to achieve neutral
buoyancy on the surface with an empty tank. During the dive, you can
then correct the buoyancy by adding and draining the right amount of
air.
Conventional waist weight belt
A conventional waist weight belt should never be connected to the
BCD.
Inflator
DYNAMICNORD BCDs are equipped with an inflator. When the inflator
is connected to the regulator and – using the quick-connect coupler
– to the inflator itself it allows for buoyancy control in the water (BCD
inflation/deflation) using the inflate and deflate buttons.
Connecting the inflator
The BCD is filled with air from your SCUBA cylinder via the inflator
valve. The LP hose screwed onto the low pressure port of the
regulator’s first stage is connected to the inflator valve using the
quick connector. It can be coupled and uncoupled under pressure or
without pressure.
Attaching the quick connector:
Make sure both couplers are free of debris before connecting
them.
Pull back on the quick connector collar while firmly pressing the
hose onto the coupler plug on the inflator valve.
When the coupler is firmly seated on the coupler plug, release the
collar. Check that the connection is secure by gently but firmly
pulling on the hose.
To disconnect, pull back on the quick connector collar and
disconnect the LP hose from the coupler plug.
KEEP THE BCD’S INFLATABLE BUOYANCY CHAMBER
FREE OF WATER. REPEATED USE OF THE ORAL VALVE OR
THE PRESSURE RELIEF VALVE MAY CAUSE WATER TO
ENTER INTO THE BCD, WHICH REDUCES THE AMOUNT
OF BUOYANCY PROVIDED BY THE BCD. THIS CAN RESULT
IN INJURY OR DEATH. DRAIN ALL WATER FROM THE BCD
BEFORE EACH USE.
WARNING

ENGLISH
Using the inflator
INFLATION
Inflating the BCD using the inflator valve
To inflate the BCD, press the inflator valve button (fig. 6-P). Air should
begin to flow into the BCD. By briefly pressing the inflator button
repeatedly you can easily control the amount of air during inflation.
Inflating the BCD orally
The mouthpiece is located at the end of the inflator. You can use it to
inflate your BCD with your exhaled air. It is recommended to inflate
the BCD using the mouthpiece on the surface prior to diving. It can
also be used underwater if you cannot or do not want to inflate your
BCD using the inflator valve.
First exhale a small amount of air into the mouthpiece of the valve
to purge any water that may be trapped there.
With the same breath, continue to exhale while deeply depressing
the inflate button.
Release the inflate button when you inhale fresh air.
Repeat steps 2 and 3 until the desired amount of buoyancy is
reached.
DEFLATION
Deating the BCD using the manual drain valve on the corrugated hose
Assume an upright position in the water. When in an upright position,
open the manual drain valve as follows:
Gently pull on the corrugated hose (see fig. on the right). It is not
necessary to pull too hard on the hose assembly. There is a limit
to how much the valve opens and pulling harder will not increase
the airflow. To close the manual drain valve, stop pulling on the
corrugated hose and simply let it go.
Deflating the BCD with the oral valve of the inflator
Assume an upright position in the water. Raise the mouthpiece so
that it is higher than your shoulders. It thereby reaches the highest
point and you can completely deflate your BCD. Press the air release
button on the oral valve and watch how your buoyancy changes.
Keep the oral valve of the mouthpiece and valve button free
of sand and other debris. Under certain circumstances,
debris can prevent the valve from closing fully. If this
happens during a dive, shake the valve by pressing it several
times. If the valve continues to leak or to be inoperable, abort
the dive. Diving with a leaking BCD or with valves that are not
working properly can result in loss of buoyancy control and
injury or death.
WARNING

1918
ENGLISH
The draining xtures offering the maximum air drain are the
shoulder valve and the lower valve.
Lower and upper drain valve right side
At the right rear of the BCD is a pressure relief valve equipped with
a pull button and pull cord. This lower drain valve can be manually
activated when the diver is in a horizontal or inverted position in the
water and the valve is at the top of the BCD’s air bladder.
The same can be done with the combined pressure relief and drain
valve in the upright position.
Function of the pressure relief valve
The pressure relief valve prevents over-inflation of the BCD. If the
internal pressure exceeds the spring pressure in the pressure relief
valve, the valve automatically opens and releases air to prevent
damage to the BCD. The valve will automatically close when the
internal pressure falls below the spring pressure in the pressure relief
valve.
Adjusting the harness
Opening and securing the straps
So that it can be opened and closed quickly, the BCD has quick-
release buckles on both shoulders, on the chest and on the
cummerbund. See figure on next page.
The cummerbund also features a Velcro system. All fasteners can be
opened with one hand.
Adjustable shoulders
The BCD’s upper shoulder straps are not adjustable. The length of
the lower straps is adjusted using a movable quick-release buckle
through which the strap is routed. To shorten it, grab the free end of
the strap and pull it down firmly. To lengthen the strap, lift the front
portion of the buckle while wearing the BCD.
Adjusting the BCD to different body sizes
All DYNAMICNORD BCDs allow for optimal size adjustment by
combining different adjustment options. If necessary, the waist belt
can also be adjusted quickly and easily under the back padding.
Cummerbund
The cummerbund should be fastened around the waist (above the
hips) and NOT around the rib cage or diaphragm, with at least two
centimeters overlap at the Velcro. The side panels are attached to the
back plate and can be adjusted in length. See figure on next page. It is
important to ensure that the BCD is not worn too high on the body as
this will result in an undesirably high center of gravity and may cause
discomfort or shortness of breath.
WARNING
WARNING
Adjust the BCD so that it does not interfere with your breath-
ing when fully inated. Restriction of normal breathing while
wearing the BCD can result in injury or death. Before each
use, check that all belts, straps, quick-release buckles and/or
the cummerbund are adjusted correctly for the user.

ENGLISH
Checking and use
BCD checks before, during and after a dive help identify equipment
problems before an unsafe situation arises. The entire equipment
must be inspected regularly by an authorized diving equipment repair
shop.
Pre-dive visual inspection and valve check:
Inspect the entire BCD for cuts, punctures, frayed stitching,
excessive wear, loose or missing parts, and other damage.
Check that the drain valves and corrugated hose are tight.
Inspect the oral valve, inflator valve, manual drain valve, and
pressure relief valves for cracks, damage, or debris.
Actuate the inflator valve (with LP hose pressurized and
connected), oral valve, manual drain valve and pressure relief
valve(s) and verify that the valves are working properly and close
again. Check pressure relief valves with pull-cords by pulling on
the cord.
Using the oral valve, fully inflate the BCD. Check if any air
escapes. Keep the BCD inflated for at least 30 minutes and then
check if it has lost any air.
Soak the tank strap and attach the BCD to the tank. Lift the unit
by the BCD to ensure the BCD will not shift while diving.
Put the BCD on and adjust the straps and other attachments on
the BCD, so it is comfortable to wear and does not obstruct your
breathing. Make these adjustments with the BCD inflated and
wearing the wetsuit you will be using for the dive.
Check that all valves are working properly and visually inspect
your BCDs with your buddy before each dive.
If necessary, the waist belt can also be adjusted quickly and
easily under the back padding.
WARNING
NEVER DIVE with a BCD that did not pass any of the
inspections and checks before, during or after the dive. Loss
of buoyancy control or air-tightness can result in serious
injury or death.

With proper care and maintenance, you will be able enjoy your BCD
for years to come.
Follow the following care and maintenance instructions:
After each use, thoroughly rinse the BCD inside and out with fresh
water (do not use aggressive solvents or detergents).
Fill the BCD’s buoyancy chamber up to a quarter full with clean
fresh water using the oral valve.
Inflate the BCD using the oral valve and shake it to distribute the
water.
Hold the BCD upside down and press the button on the oral valve
to drain all water and air through the mouthpiece.
Repeat once or twice.
Rinse the entire BCD with fresh water by submerging it in a basin
or by spraying it with a hose.
Rinse all valves to ensure that no sand or other debris remains.
Drying the BCD: Keep the BCD away from direct sunlight when
hanging it up. Let it dry completely before storing it while slightly
inflated.
Storage
Store your BCD after it has dried completely. Slightly inflate the BCD
and store it in a cool, dark, dry place. UV rays shorten the life of the
fabric and cause the colors to fade.
Inspection and service interval
Your BCD must be inspected and serviced at least once a year by
an authorized service center. If you dive frequently, we recommend
inspecting it more often. Any damage caused by lack of proper
maintenance of your BCD is not covered by the warranty.
NEVER DIVE with a BCD that is damaged, leaking air,
or malfunctioning. If your BCD gets damaged, leaks air, or
malfunctions, abort the dive as safely and as quickly as
possible.
WARNING
Avoid prolonged or repeated exposure to chlorinated water
as used in swimming pools. Immediately wash your BCD
after each use in chlorinated water. Chlorinated water can
oxidize the fabrics and materials of your BCD which shortens
its life and can cause the colors to fade. Damage and fading
caused by prolonged exposure to chlorinated water are not
covered by the warranty.

Risk assessment and management
Possible risks when using the BCD
NOTE: Risk assessment is not an exact science, but tries to describe
all conceivable scenarios.
Your BCD is part of the diving equipment. The use is thus limited to
diving in water.
Your BCD enables you to control buoyancy
and, in an emergency, to return to the surface.
Your BCD is designed to ensure safe operation of your inatable
buoyancy compensator for diving and carrying systems, which meets the
requirements and tests of the harmonized standard EN1809: 2014 + A1:
2016.
POSSIBLE ALLERGY RISKS
A small percentage of the population suffers from allergies to fabrics
used in the BCD. Allergic symptoms can range from mild to severe
skin irritation or itching. It is the user’s responsibility to determine
if he or she has any allergies or to determine this while using the
BCD. It should not be used until the problem can be solved. The
DYNAMICNORD BCDs are not designed for use on bare skin and may
only be worn over a suitable diving suit to avoid friction on the skin.
Fault finding
IT IS VERY IMPORTANT THAT DISCOMFORT IS RECOGNIZED
AS A DANGER SIGNAL. AVOID HYPERTHERMIA AND
HYPOTHERMIA AS BOTH ARE HARMFUL AND CAN LEAD
TO DEATH. MONITOR YOUR PERFORMANCE DURING
ALL DIVING ACTIVITIES AND AVOID EXCESSIVE AIR
