3.3.7 Insert a deflator pin into the vacuum valve body and leave the liferaft
to settle to atmospheric pressure. (This takes approximately 5-10
minutes). When atmospheric pressure has been reached, a pressure
reading will return 0 p.s.i.
3.3.8 Fit the plug provided with the H-Pack (Item 1 FIGURE A2-33).
Torque plug into vacuum valve body, using the correct tool and a
calibrated 3/8” square drive torque wrench. Ensure that silicone
grease does not come into contact with any threadforms on the plug
or vacuum valve body.
NOTE:
The plug supplied with H-Pack has an integral O-ring
(Item 3 FIGURE A2-33). Silicone grease is already
provided on the O-ring. This is sufficient for re-fitting
the plug directly, provided the plug has been kept free
of contaminants and grease provided hasn’t been wiped
off. If in any doubt, remove the O-ring using a suitable
non-sharp implement and discard. Clean the plug using
a clean lint-free cloth and refit a new O-ring coated
liberally with silicone grease.
