WARNING!
The oxygen injector is a convenience. It is not a controller in any way. The only device regu‐
la ng the oxygen par al pressure is your brain. The automa c oxygen add does not reduce
the need to monitor the three par al pressure displays. It only reduces the number of mes
you have to press the oxygen add bu on. The displays should be checked constantly during
the dive. The oxygen regulator can fail and stop delivering 02 or it can fail and increase the
flow dras cally. The orifice can become plugged and stop delivering oxygen. The add valve
O‐rings can fail and increase the amount of 02 being added to the breathing loop. Any of
these things can kill you but any of these problems can be overcome if you are aware of the
condi ons in the breathing loop.
The manual oxygen addi on valve is a key component of the KISS diving system; care
should be taken to ensure that it is not damaged, serviced as required and is func oning
properly.
DIVER SHOULD BE CHECKING THEIR PPO2 DISPLAYS EVERY MINUTE.
KNOW YOUR PPO2 AT ALL TIMES... OR YOU WILL DIE!!
Manual Add Valve Troubleshoo ng
If the flow rate is lower than it should be in rela on to the pressure, one of the following things has happened:

The filter has become clogged and should be replaced.

The orifice has become par ally plugged and must be replaced.
DO NOT TRY TO CORRECT A LOW FLOW RATE BY INCREASING THE REGULATOR PRESSURE!
If the flow rate is higher than it should be in rela on to the pressure one of the following things has happened:

The orifice has become loose where it screws onto the valve.

The valve O‐ring is worn or damaged.

The spring is broken or weakened and is not holding the valve closed.
The oxygen first stage will have a plas c plug installed to prevent the pressure from increasing with depth and increas‐
ing the oxygen flow rate. If the pressure is inconsistent the high pressure seat or diaphragm may be damaged. The reg‐
ulator should be serviced regularly and maintained in an oxygen clean condi on.
*WARNING: It is very important that this valve is in good working order, with proper flow
rates and good O‐rings. Ensure that you rinse your gear a er diving in salt water, and if you
flood your rebreather, and you think water has go en into the valve, service it!! If you pay
a en on to how o en you usually add oxygen to your rebreather during a typical dive, it
will be easier for you to no ce a problem.
