Olympus FL-50 user manual Housing is now ready for the dive

(Fig. 7)

Screw home the pressure release plug (Fig. 7). There is no need to excessively tighten this plug. The seal is made by internal O-rings. The O-ring on the underside of the plug is just to keep out dirt.

After replacing the lid, make a final visual inspection of the main O-ring for contamination (Fig. 8)

(Fig. 8)

Note: If the O-ring is in good contact, a thin black line, about 0.5-1mm 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).
