After replacing the lid, make a final visual inspection of the main O-ring for contamination (Fig. 10).

(Fig. 10)

Note: If the O-ring is in good contact, a thin black line, about 0.5 to 1mm in width should be

visible, where the O-ring is in contact with the lid. Follow this line all the way round the edge

of the seal, as a final check that the seal is good. The housing is now ready for the dive.

Important !!!

Before diving, make sure the pressure release plug is pushed

back inside and then screwed home, do not over tighten this plug (finger

tight only).
