Bladder
It is made of Cordura polyurethane coated (Models GR13, 15, 19 and 19R) or nylon
polyurethane double-coated (Models GR TEK).
Harness
The harness are made of 50mm polyethylene reinforced polypropylene and are completed
by five “D” rings of AISI 304 stainless steel that allow to connect to the harness different
diving accessories. The buckle is also of AISI 304 stainless steel. The belt slides inside a
series of AISI 304 stainless steel loops in order to adapt the harness to any size between
the S and XXL.
Backplate:
The backplate is made of electro polished AISI 304 stainless steel or of aluminum; nuts
and bolts of AISI 304 stainless steel.
Power inflator and overpressure valves
For safety reasons, we recommend that the first time you try to use the inflate button
when you are in surface.
The power inflator of the BCD controls a large number of functions and allows to adjust
the BCD to get a neutral trim during the dive:
Load by the button of the inflator (side button); pressing this button inflates the
BCD; it can be inflated up to a pre-established pressure that depends on the
calibration of the overpressure valve; once the maximum pressure is reached, the
air is discharged from the valve.
The top button (at the end of power inflator) allows the inflation by mouth with a
special mouthpiece: push the button and in the same time blow inside the
mouthpiece.
The top button (at the end of power inflator) allows the deflation by raising the
corrugated upwards and pressing.
Page11of34
DANGER :
Never use the inflator mouthpiece as a regulator. The BCD is not a breathing
device. Never breathe gas from inside the BCD, it may contain liquids or
contaminants that, if inhaled, could lead to serious injuries or, in extreme
situations, to death.
Overpressure valves
The BCDs are supplied with one overpressure valve located behind on the left side at the
bottom. The overpressure valves guarantee the quick dumping of air. The function of
these valves is to automatically reduce the inner pressure of the bladder in case of
excessive inflation or in case of eventual necessity during the various phases of diving.
The valves can be opened manually pulling the cable located on the valve itself.
WARNING :
To obtain complete redundancy, only the Model GR 19 R is composed of two
independent bladders coupled. Each bladder has a complete control unit and an
overpressure and rapid discharge valve: in this case the overpressure valves are located at
the bottom, right and left.

(Fig. 102) (Fig. 103)
PRE DIVE PREPARATION
The BCD is supplied as accessory with a low pressure hose (LP) with quick release
connection that provides low pressure air to the inflator. The hose must be connected in
one of the low pressure ports (LP) of your regulator.
WARNING :
Use only air to inflate the stabilizing jacket. The use of oxygen-enriched gas
may cause fire and explosion.
KNIGHT DIVERS Ltd always uses hoses certified according to EN 1809, EN 250 and EN
14225-2 standards, with working pressure up to 12 bars; the thread is the standard
3/8"UNF and the quick release can also be operated with thick gloves. The gas flow that
feeds the filling valve is abundant, no pressure drops occur even in conditions of intense
cold.
WARNING :
Never connect a low pressure (LP) hose to a high-pressure (HP) port of your
regulator. If a low pressure hose is connected to high-pressure, may stop
working without warning, causing serious injury to the person.
The first stages of the regulators have the low pressure ports (LP) smaller (3/8" X 24 UNF
thread) then the high pressure ports (HP) (7/16" X 20 UNF thread). In any case, it is
necessary to pay attention to the old regulators in which the HP and LP ports were all the
same. In most cases, the HP ports are marked HP. In any doubtful case, carefully check
output pressure. The maximum pressure of an LP port should be around 14 bars. Use a
common 4mm Allen wrench to remove the low pressure (LP) cap. Once it is localized the
low pressure port and has removed the plug, make sure the O-Ring is present on the hose
and in good condition. Also check the hose to make sure that the threads and O-Rings are
Page30of34
free of dirt and debris. Install the threaded portion of the hose in the LP port using a
14mm wrench. Do not over tighten (exactly with a torque of 14.7 Nm).
WARNING :
If the hose supplied with your KNIGHT DIVERS BCD is bent, twisted or forced
when worn, the load valve may not work properly; replace it immediately with
a new hose KNIGHT DIVERS.
We advise you to follow our recommendations described here in order to avoid problems
during the dive.
Before every dive, verify that the rings nuts are firmly screwed on the inflator and the
valve; inflate completely the stabilizing jacket and wait at least 30 minutes to make sure
that it is kept expanded: if it is deflated, do not proceed to the dive before you fix the
problem.
The first step to be taken is to attach the BCD to the cylinder, positioning the cylinder with
the outlet valves facing you, insert the stabilizing jacket, maintaining the rear part of the
backrest in front of the valve. Tighten the band on the cylinder and close the special
buckles; secure any excess strap length using the special strips provided. By tightening
the band on the cylinder while dry you may notice loosening of tension when diving with
consequential slipping of the cylinder. We therefore recommend wetting the bands before
carrying out this operation.
If you use a double tank, follow the instructions on page 28.
Adjust the harness straps according to your size and sort of equipment used. Proper
adjustment will allow you maximum comfort, stability and safety.
At this point, put on the BCD and assume an erect position, lowering the nape of your
neck backwards: if your body position is correct, you should have no problem carrying out
this operation. At the same time, check that the base of the cylinder does not move
downwards excessively, disturbing your movements. We advise you to mark a fixed
reference point on the cylinder- for example, a strip of adhesive tape or painted line - so
that you can always re-assemble your BCD in the correct position.
Page31of34
CAUTION :
The Optimal Position is obtained by fixing the cylinder to the BCD in such a way that
the valves are always placed above the upper edge of the Wing (Fig. 104-105) and that
the first stage of the regulator and the various hoses, of low and high pressure, do not
interfere with the free movement of the Wing.
(Fig. 104) (Fig. 105)
Remember that the attachment system is designed to assemble a single cylinder (with a
minimum diameter of 170mm and a maximum of 220mm). You can attach also twin
cylinders (maximum 12 + 12 with a minimum diameter of 170mm) with the appropriate
accessories.
After opening the cylinder valve, connect the quick release attach with the male connector
on the inflator taking between thumb and forefinger the collar of the quick release attach,
slide it back and press down firmly on the male connector of the inflator, then release the
collar. To disconnect the quick release attach simply slide back the collar and the hose will
release automatically.
Arrange the shoulder straps and the belts to the maximum expansion for easy donning.
Slide your arms through the shoulder straps taking care to leave over your shoulder all the
low and high pressure hoses. Inhale deeply and tightened the straps on the shoulders,
chest and abdomen, making it adheres well to the body so it does not hinder or impede
movement or cause any sensation of oppression. Attach the crotch strap to the belt and
proceed to wear the ballast belt.
Page32of34
WARNING :
If you use a ballast belt, remember to place it above the crotch strap so that, in
an emergency, it can be quickly abandoned without getting caught in the
straps. Failure to observe this precaution could result in serious injury to the
diver.
Be careful, always partially deflate the stabilizing jacket before entering the water to
compensate for any additional weight.
Start the dive deflating the bag using:
Option 1 – put the inflator over your shoulders and press the exhaust button on the
top (slow discharge)
Option 2 – upside down, pull the knob on the cord of the pressure relief valve
(rapid discharge).
Once you start the descent, the speed tends to increase: short bursts of load button
allows you to adjust it. To the desired depth, by the load button, always established
neutral buoyancy with small inputs and calibrated air.
During the ascent, maintain a slightly negative attitude to earn the surface.
WARNING :
Improper use of the inflator can cause you to lose rapidly buoyancy and uncontrolled
ascents and descents, with serious consequences. In surface inflate the stabilizing jacket
to have a positive attitude; to undress the jacket open or loosen the abdominal buckle and
the crotch strap.
WARNING :
The stabilizing jacket is used to compensate underwater trim, cannot be used to lift heavy
objects from the bottom since this could cause uncontrolled ascents with serious
consequences.
Page33of34
MAINTENANCE ROUTINE
All KNIGHT DIVERS BCD are manufactured and individually tested with strict criteria of
quality control. The proper maintenance of your stabilizing jacket will be extremely useful
to extend its life.
When you finish diving for the day, rinse thoroughly with fresh water both the external
and the internal face. To do this, enter the fresh water through the drain button air of the
inflator, then flip the jacket and empty it by pressing the same exhaust button. Rinse
carefully the drain and load valves. Dry the valves with compressed air after rinsing. Let
the jacket dry in the shade. Do not put the jacket with objects that could puncture or
damage the bladder, avoid contact with solvents, oils, gasoline. Put the jacket perfectly
dry, partially inflated, in a cool and airy place. Pay particular attention to the valves.
WARNING :
The valves of the stabilizing jacket must be cleaned after each use exactly as
your regulator. The load valve may be sticky due to the accumulation of salt.
The exhaust valves may be clogged due to deposits of salt or limestone inside
the mechanism.
CAUTION :
Do not hang your stabilizing jacket in full sun.
STORAGE OF THE STABILIZING JACKET
Proper storage will extend the life of your stabilizing jacket. Keep it in a cool, dry place
and away from direct sunlight. The place of storage should be free of ozone generators,
such as electrical machinery or gas.
