Kiss Classic
CCR
The Classic Kiss Closed Circuit rebreather is
a durable machine which has been designed for
both recreational and technical diving. If you
are looking for a CCR that will take you from
shallow reef dives to deeper trimix dives, this
unit is for you!
Oxygen Addition
Oxygen addition on the KISS rebreathers is what
we call a buffered manual control system. The
oxygen is added in two ways. Via the manual add
valve, continuous flow and manually.
By continuous flow: The manual add valve holds
the 0.0035 orifice. Once the oxygen valve on the
cylinder has been turned on, there will be a
constant flow of oxygen into the rebreather at
all times. The flow rate is adjustable and can
be set as high as 1 liter per minute. But most
divers will want to keep it around 0.5 to 0.7
liters per minute.
The flow rate is just enough to keep the diver
from becoming too busy underwater. What does
this mean for the diver? When he reaches his
desired operating depth, the PPO2 is manually
adjusted and brought to the appropriate level.
As long as the diver isn’t working hard or
moving up and down in the water column, oxygen
will be added infrequently.
How does a diver determine where the flow rate
should be set? The simplest way is to go diving.
Are you constantly adding gas, even while at
depth, when you aren’t working hard or moving up
and down? If this is the case, then the flow
rate should be increased. Are you finding that
the PPO2 is slowly increasing during normal
diving activities? If yes, then more oxygen than
the diver can metabolize is flowing into the
loop. The flow rate should be reduced.
Manually: Oxygen can be added to the loop
manually by pushing the manual add valve button.
In general, when the valve button is not
depressed, the oxygen is forced through the
0.0035 orifice at a steady rate. When the button
is depressed, it is like a door has been opened
and a larger amount of gas is allowed through
the valve. The diver will push the button more
at shallow depths and less at deeper depths.
Jetsam PPO2 Displays
The Jetsam displays have three independent,
backlit PPO2 displays. Each display has its own
housing, battery and sensor, making the system
completely redundant. The batteries are user
changeable. Each display can be replaced
independently and spares are easily affordable.
Another option is a real time decompression link
up to the VR3 (monitoring all three cells) when
purchasing a Kiss or as an after purchace add
on. Instead of the display seen above it would
come with a pendent seen below and VR3.
The Last option on the PPO2 displays is 2
standard displays and a VR3 or VR2 linked into
one cell. As seen below.
Scrubber Canister
The Classic KISS scrubber canister has an axial
flow design. It is a durable, easy to fill
canister which holds approximately 6 pounds of
absorbent. Sofnolime 797 grade of absorbent was
used for testing. The gas flows down the center
of the scrubber tube and then comes up through
the scrubber material where the carbon dioxide
is scrubbed out.
The canister is accessed by removing the “hat”
from the scrubber head. Then using the special
KISS tool the large bronze draw nut is removed.
The canister is now loose and can be removed
from the scrubber head.

Bailout Mouthpiece
The Classic KISS Dive Surface Valve (DSV) has a built-in
bailout 2nd stage regulator; this means that the diver can
go from closed circuit to open circuit with a twist of a
knob. The knob on the DSV is used to either open the
rebreathers breathing loop or when closed, allow the diver
to breath in open circuit mode.
The DSV can provide the diver with an alternate method of
adding diluent gas or even an alternative diluent depending
on the connection. It is a simple way to purge the
rebreather for verifying the sensor readings. Also, it can
prevent panic in the case of a malfunction in the rebreather
by allowing a fast, simple way of getting your next breath.
NOTE: * The diluent bottle is not adequate bailout. When
diving a rebreather, a separate bailout bottle should always
be carried.
Counterlungs
The Classic KISS uses 2 individual back mounted
counterlungs, and are attached to the scrubber head from
the inside of the counterlung case. Back mounted lungs
leave the diver’s chest area clear and reduce the number
of hoses and fittings compared to the over the shoulder
counterlungs found on other rebreathers. The lungs are
MSR heavy duty dromedary bags. They are inexpensive to
replace and readily available worldwide. The Classic
comes standard with a 2 liter and a 4 liter counterlung.
Smaller and larger sizes are available upon request.
With the Classic KISS rebreather, it is important that
the counterlung volume match the diver’s tidal volume.
This will give the diver exceptional buoyancy control
and eliminate the risk of overfilling the lungs. It is
also important that the rebreather sit tight and as high
up on the diver’s back as possible for the best work of
breathing (WOB). A high WOB can be caused by an
ill-fitting harness which allows the unit to float away
from the diver’s body.
Automatic
Diluent Valve
The automatic diluent valve (ADV) on the Classic KISS is
used to draw the diluent gas into the breathing loop. A
diluent gas is necessary as the loop must be filled with a
breathable gas mixture. As we drop in the water column, the
gas in the loop compresses and the volume left will not be
enough to breathe. The volume of the loop will also be
decreased as you metabolize the oxygen
When the volume of gas in the loop has decreased, the diver
simply inhales hard to trigger the ADV. The operation is
similar to a 2nd stage regulator. Suddenly finding yourself
unable to get a breath during a rapid descent could be a
panic inducing situation. The ADV will help eliminate that
as no hands are required to trigger it.
The diluent gas can be air, nitrox or trimix. Generally air
or trimix are normally used and the nitrox is reserved for
shallow applications, such as pool demos or shallow reef
diving.
Diluent can be added several different ways:
ADV: Using the ADV to add diluent gas to the loop is simple
and convenient as it has a hands-free operation. This valve
is triggered when the gas in the loop has either compressed
or the loop has been breathed down.
DSV: Diluent can also be added two other ways using the DSV.
First, the diver can close the breathing loop completely and
go to open circuit mode. The diver takes a breath off open
circuit and then opens the DSV and exhales
the
gas into the loop.
Lastly, diluent can be added by turning the knob on the DSV
towards the closed position only a quarter inch, for a
couple of seconds. This will cause the second stage to
trigger and gas will blow directly into the loop.
Cylinders and Attachment Methods
A variety of cylinder sizes can be used with the Classic
KISS; with 13 cuft cylinders having the most advantages. As
the limiting factor on a rebreather is the scrubber
duration, this provides plenty of gas. A 13 cuft oxygen
cylinder will provide 5 hours of oxygen at a consumption
rate of 1 liter per minute. A 13 cuft diluent cylinder will
provide enough gas for an experienced rebreather diver to do
two,
1 hour long dives to 150 ft.
Jetsam highly recommends that you carry more gas than just
the diluent. It should be in the form of emergency bailout,
open circuit gas in a separate cylinder. A larger diluent
cylinder is not an adequate bailout gas supply.
Other advantages to using 13 cuft cylinders are the size and
weight. They fit the Classic KISS well and have good
balance. They are easy to travel with to a local dive spot
and also pack easily in a suitcase for an over seas trip.
The Classic KISS uses a hose clamp system for cylinder
mounting. The mounting brackets do have large slots so any
other mounting system on the market can also be used.
