The gas mix within the cylinders is not breathable at atmospheric pressure therefore venting must
be carried out in a well-ventilated area to avoid hazards.
2. Leave the SLS System for at least 5 minutes until the last of the gas is vented. Check that the
contents gauge reads ‘zero’ before disconnecting pipework for maintenance.
3.4.4 Reloading the actuation cable assembly
After actuation of the SLS System, the actuation cable assembly will require reloading. Reload the
actuation cable assembly as follows.
1. Ensure that the spool valve is in the actuated position before attempting to reload the
Actuation Cable (section 3.4.5).
2. Push the ‘long’ counterlung cable back into the actuation handle until it reaches the stop.
3. Enter all three actuation cables into the cable sleeve at the entry point on the harness
waistband.

Ensure that the individual cables are not crossed, i.e. arrange for the handle to lie naturally against
the block at the entry point to the cable sleeve.
4. Push the cables fully home until the handle is against the block on the cable sleeve,
thereafter, press the Velcro pads on the harness together to retain the handle.
5. Reset the spool valve on the two stage regulator (section 3.4.5).
6. Repack the counterlungs using the two actuation cable tails protruding from the actuation
sleeve, by lacing the cable through Teflon bushes from left to right (in an alternate manner,
starting with the Teflon bush closest to the cable wiper) then pull the cable tight until the
Teflon bushes naturally interface and align.
7. Check that the actuation bullet is visible at the end of the regulator spool valve then reset the
spool.

(1) When this is being carried out, the internal cover flap should be arranged in position and the
tongue at the lower end of the enclosure should be folded in place as the lacing up is finalised.
(2) The flap and tongue provide protection for the counterlungs against abrasion.
8. Finally push the tongue of the counterlung pouch material up inside the pouch to protect the
bottom end of the counterlungs.
