Ideally, the lung size should be as evenly matched to your own lungs as possible. If you find that when doing this test
you can get more than one full breath into the loop before it is full, then cinch down the straps. Never use counter‐
lung's where the volume is smaller than your own! Very small people may require a 2&4 liter to ensure proper place‐
ment, while most people will use 4&4 liter lungs. Those with very large lung volumes may require 4&6 liter lungs.
In matching your dal volume to the counterlung volume, you will find that your buoyancy in shallow water can be ex‐
cep onal. Only KISS divers can hold their posi on in water that is only 3 to 4 feet deep. If you are finding buoyancy
difficult in water this shallow, this is due to either being new on the rebreather or the counterlung’s are too large.
While doing this test at the surface, remember that underwater your required volume won’t change. If you find that
your surface test went well, but it feels like the lungs are too small underwater, you probably have too much gas in the
loop. To correct this, exhale some of the gas out of your nose. Or, you failed ensure that the lungs weren’t twisted
when threaded through the wing, then this will cause either a decrease in lung volume &/or will increase the work of
breathing. See the work of breathing pages for more informa on.
*NOTE: The closer you can match the counterlung volume with your own, the be er your
buoyancy will be. Diving the KISS OS with counterlung with the straps FULLY open will re‐
sult in greater buoyancy changes. This can cause the user to lose control of their buoyancy
which can lead to injury or death!!
AUTOMATIC DILUENT VALVE (ADV):
The ADV is located on the top of the gas addi on scrubber head. The ADV will add diluent gas to
your breathing loop a er the loop volume has been reduced by either descending or “breathing
down” the volume of oxygen. The diver will get the feeling that there is no more air in the loop to
breath. All the diver needs to do is suck hard to trigger the ADV and it will feed him more gas. This
is how a second stage regulator works.
The ADV has been setup “ ght” enough that it doesn’t add diluent without the diver being aware. But it adds enough
gas so that a reasonable descent rate can be maintained. As you can see, there is an adjustment knob on the ADV reg‐
ulator. It is very important that this knob is always ght, and turned all the way in. The ADV on the KISS OS has been
designed to be easier to ac vate then past ADV designs. As such, diver’s must be aware of body posi on at all mes
and understand that a head‐down posi on will cause the ADV to ac vate more rapidly then usual. If the diver is in this
posi on, then he must be prepared to vent the loop and change to a horizontal posi on. This will aid in preven ng a
buoyancy issue, which is may cause an unwanted ascent.
*WARNING: THE ADJUSTMENT KNOB ON THE ADV REGULATOR MUST ALWAYS BE TIGHT
AND TURNED ALL THE WAY IN. ALSO, THE DIVER SHOULD BE AWARE THAT IN A HEAD‐
DOWN POSITION THE ADV MAY TRIGGER MORE RAPIDLY, CAUSING A RAPID ADDITION OF
GAS. THIS WILL CAUSE BUOYANCY ISSUES WHICH MAY CAUSE THE DIVER TO HAVE AN UN‐
CONTROLLED ASCENT, WHICH MAY LEAD TO INJURY OR DEATH!
Any me the ADV triggers you need to check your PPO2. you have either descended and compressed the gas in the
loop or you have consumed enough oxygen to reduce the PPO2 significantly . This may also have caused you to lose
buoyancy and descend.
The posi on of the diver will effect the ADV. If the diver is horizontal or face down, the ADV will trigger easily. If the
diver is ver cal, then it is more difficult to trigger. (A well fi ng harness is important; this will greatly reduce the diffi‐
cul es of being ver cal in the water).
