(1) Always ensure the CO
2
scrubber canister is correctly installed prior to diving.
(2) Ensure that the scrubber door is not over-tightened (see section 4.5.1, page 78).
(3) Do not pressurise or de-pressurise the scrubber canister too rapidly during transfer in and out of
the equipment lock or medi-lock, otherwise damage may occur.
(4) Do not fit the CO
2
scrubber canister inside a plastic bag or other sealed containers before
locking it into the complex as the pressurisation will destroy the canister wire mesh during
compression if the bag is sealed.

(1) The SLS System’s CO
2
canister endurance at 400 msw is demonstrated in Fig 1.11. All
experimental testing during the SLS System’s development was conducted using 797 grade
sodalime (self indicating), Divex Order Code: CM007. The system has been specifically
designed to use this high efficiency product. Use of alternatives could seriously compromise the
system’s performance.
(2) Care should be taken at all times to avoid getting the CO
2
scrubber canister wet.
1.
Remove the scrubber canister from the SLS System (section 3.1.2).
2.
Remove the screw cap, the foam pad and the cap gasket.
3.
Half fill the canister with sodalime.
4.
Snake and tap the canister until the sodalime settles.
5.
Completely fill the canister with sodalime to the top of the neck.
6.
Fit the foam pad and the screw cap and invert the canister to settle the sodalime.
7.
Remove the screw cap and foam pad.
8.
Repeat steps 5., 6. and 7.
9.
Top up the sodalime to halfway up the neck.
10.
Repeat sets 5. and 6. until the canister is full.
11.
Fit the cap gasket making sure that the blade is horizontal (to align with the canister rib) insert
the foam pad and do up the screw cap.
