4.5.2.2 Inhale / exhale hose penetrators
1.
Release the wing nut and remove the thermal regenerator (Fig 3.7, Item 1, page 48).
2.
Peel off the scrubber canister gasket (Fig 3.7, Item 2) and carefully remove the RH / LH
regenerator housing (Fig 3.7, Item 3 / 4) as required.
3.
Using the duct spanner (Divex Part No. M2921B) engaged in the upper penetrator slots and
the locknut spanner (Divex Part No. M2920) from the Tool and Test Kit, undo the locknut (Fig
4.11, Item 2) and remove.
4.
Push down on the upper penetrator to break the hold of the silicone sealant and remove.
5.
Clean off the old silicone and wipe the contact areas with silicone primer (Divex Part No.
SM021).
6.
Fit a new O-ring (Fig 4.11, Item 3) to the upper penetrator (Fig 4.11, Item 1) and apply a bead
of silicone sealant (Divex Part No. SM006) around the sealing face of the penetrator.
7.
Re-install the penetrator into the scrubber housing and refit the locknut (Fig 4.11, Item 2)
using the tools described in Step 3 above, and with a moistened finger carefully wipe the
excess silicone sealant smooth before it sets.
8.
Carefully clean off the old silicone sealant from the regenerator housing, gasket sealing area
and the regenerator housing sealing area, and wipe all these areas with silicone primer
(Divex Part No. SM021).
9.
Re-install the regenerator housing with a generous bead of silicone sealant (Divex Part No.
SM006) ensuring a gas tight seal.
10.
Inspect the sealing area for the scrubber canister gasket (Fig 3.9, Item 2). Check that all
traces of silicone sealant have been removed.
N
OTE
Check the orientation of the gasket - the narrowest end goes in first.
11.
Prime the gasket and the sealing area with silicone primer (Divex Part No. SM021) and apply
a bead of silicone sealant (Divex Part No. SM006) to the face of the gasket. Insert the gasket
carefully, ensuring that the gasket is sitting flat and that the rectangular cut-out aligns with the
inner edges of the regenerator housing.
12.
While the sealant is still wet insert a scrubber canister and engage the canister lift mechanism
to squeeze the gasket into place. Allow the sealant at least eight (8) hours to cure before
releasing the canister lift mechanism.
13.
After the sealant has cured for at least twelve (12) hours, check the regenerator housing
sealing by pressure testing to 68 mbar (1 psi) using a dummy blank canister.
N
OTE
The SLS System should not be dived for a period of twenty four (24) hours after the silicone sealant
has been applied, to allow it to fully cure.
