Diluent can also be added to the breathing loop via the mouthpiece. Simply go to open circuit mode, take a breath and
then open the loop again and exhale the gas into the breathing loop.
Another way to add gas to the loop via the mouthpiece is to close the loop only a 1/4 inch, for a second. You may need
to lightly push the purge bu on on the front of the 2nd stage. A small amount of gas will blow directly into the breath‐
ing loop.
Quick Disconnects:
The KISS OS is shipped with a quick connect system for the loop hoses.
You will see that the towers on the scrubber heads have a lip in which the
quick disconnect hose stubs are secured. The unit is shipped standard
with 2 hose stubs which will be fi ed to your loop hoses with hose
clamps, prior to shipping.
If you choose to order your unit with the BOV, then 4 hose stubs will be
included with your kit. These extra 2 hose stubs/hose clamps are for se‐
curing the loop hoses to the BOV which also uses our quick disconnect
system.
If you choose to source your own BOV, then you will need to also source an a achment method for that BOV.
*NOTE: THE TOWERS ARE THREADED INTO THE SCRUBBER HEADS AND SEAL WITH AN O‐
RING. WHILE THE TOWERS ARE DESIGNED TO BE DIFFICULT TO TURN, IT IS STILL IM‐
PORTANT THAT THEY ARE NOT ACCIDENTLY UNSCREWED WHILE REMOVING OR INSTALLING
THE BREATHING HOSE. A LOOSE TOWER WILL LEAK!!! CHECK THE TOWERS PRIOR TO DIV‐
ING TO ENSURE THEY ARE TIGHT.
The procedure to install the hoses stubs to the loop hoses are as follows:
First soak the ends of the loop hoses in hot tap water, for several minutes. This will so en the rubber on
the hoses making it easier to install the hose stubs. Some dives may find that they need to soak the
hose ends in water that has been boiled. This will certainly make it easier.
Shake the water from the hose, and then apply silicone grease to the inside of the loop hose. It is best
to use a thicker lubricant for this, rather then a thin oxygen type lubricant. Apply lubricant to the outside of
the hose stub.
Working quickly so the hose remains so , push the hose stub onto the loop hose. Push it on as far as it
will go, but leave a few millimeters of space so it doesn’t touch the side of the stub and restrict the
movement of the ring.
Secure the hose stub using a hose clamp; ensure that the hose clamp is properly ghtened.
Ensure that the O‐ring area on the hose stubs are clean and then apply lubricant.
Push the hose stub onto the tower/BOV, lining up the lip on the tower/BOV with the space on the hose
stub.
Turn the ring to secure.
Inspect the area to ensure that all the O‐rings are properly seated and not pinched.
To remove the hose stub, push in on the stub, and then turn the ring. This is a similar method to
opening and closing a child proof medicine bo le.
