Filling the Scrubber Canister
The KISS OS has a bi‐axial scrubber design, which is resistant to channelling. It has 2 independent canisters that can
each be removed/replaced and filled independently of the other; this makes for quick and easy filling! It also makes for
easier storage of canisters due to the size and weight. Spare canisters may also be purchased for those who wish to
have spares. This is a similar design to an earlier KISS rebreather, but this is a much be er and more efficient design.
Tests have shown that the area of the scrubber canister that does the most work is the scrubber face. As the KISS OS
has dual canisters, this means that this area is doubled, which makes this system very efficient.
The KISS OS scrubber canisters hold a total of 5.3 pounds of absorbent. We use Sodasorb HP from diverssupplyinc.net.
Please see the Scrubber Dura on page for more informa on on dura on tes ng and recommended dive mes. So‐
dasorb HP is the brand of adsorbent that we used for tes ng and it is what we recommend.
The procedure to fill the scrubber canisters is as follows:

Remove the ADV LP hose which is secured to the gas addi on scrubber Head. This will allow the
gas addi on scrubber head to be removed from the canister.

On each canister, loosen the threaded ring which secures the head’s to the canister’s.

Loosen the Fastex clamp’s which secure the canister’s to the rebreather; pull the canister’s off the
head’s and set aside. (if the crossbar is s ll a ached, remove it)

If there is absorbent in the canister’s, dispose of it properly and follow the cleaning instruc ons in
this manual to prepare for filling.

At the bo om of each scrubber head, there is a double O‐ring seal. Inspect the area, and wipe
away any debris. Use a clean towel for this. It is recommended that the O‐rings be le in place
and not removed each me for inspec on. Constantly removing and replacing the radial O‐ring’s
may cause a leak if they are not seated properly. It is best to carefully wipe this area clean.

In order to prevent spillage or confusion, it is recommended that one canister is filled at a me
and then secured to one of the scrubber heads.

Fill the first canister half way, and then tap the side with a screwdriver handle or something simi‐
lar. This is required to se le the absorbent properly.

Next add more absorbent, using the bo om thread on the top of the canister as a fill line.

Press the top screen into place, and while pushing down on the screen with steady pres‐
sure, tap the side of the canister again to se le the absorbent; using a screw driver han‐
dle or similar. It is best to tap a couple of mes while pressing, spin the canister slightly
and repeat. Turning the canister slowly while tapping ensures that the top screen is
properly placed and flat and also ensures the absorbent is properly se led. The screen
needs to be lined up with the bo om thread on the top of the canister.

Note that the tapping does not need to be hard!

Once the canister is filled, the screen in place and properly posi oned, take a clean cloth and wipe off the scrubber
dust from the top and inside edge of the canister. Ensure this area is clean; it is your sealing surface!

Apply lubricant to the inside edge and top edge of the canister. You should lube these area’s very well!

Double check that the O‐ring areas on the scrubber head are s ll clean, wipe if required, and then apply lubricant
to them. These area’s should also be lubricated very well!

While holding the canister firmly, gently push and rock the scrubber head into place. This should keep the radial O‐
ring from becoming dislodged. If you push the canister on crooked, this O‐ring may pop out of posi on. This is
most likely to happen when the O‐ring is first installed. Once the canister has been in place for several hours or a
few dives it is unlikely that this O‐ring will easily be dislodged. If this O‐ring does get pinched, you may need to
change it, as the indenta on could cause a leak! Inspect the area to ensure that the O‐ring has not been pinched.
