When to maintain the O-ring seal
Remove the O-ring periodically for inspection. It is not necessary to remove, clean and re-install the
O-ring after every dive provided the O-rings are not become contaminated. As a rule of thumbs set up the
camera and housing before a day
’
s diving. If the housing is required to be opened between dives for
changing memory card or re-charging batteries, make sure the outside of the housing is thoroughly
toweled dry before opening up. After removing the lid and servicing the camera, replace the lid straight
away, rather than leaving it lying around. Before replacing the lid, check the o-rings and make sure that
no contamination such as dust, hair, salt, sand etc. has fallen onto the O-ring or O-ring recess, as a
precaution we recommend to inspect the O-ring every time the lid is opened and to carry out the
maintenance only if necessary.
Procedure
How to open the housing:
•
Place the lid on a firm non-slip level surface.
•
The O-ring can be extracted using an O-ring extractor tool
(make sure the tool as no sharp edges). Alternatively use
the flats of the thumbs to gently stretch the O-ring on two
faces thus making a small loop protruding a few mm. The
loop can then be grasped between finger and thumb, to pull
the O-ring over the lip.
•
Clean the O-ring recess (the square groove
where the O-ring sits) with a cotton bud.
•
Inspect the O-ring all the way round its
surface for damage such as
cuts tears
or
contamination. This should be done visually
and also by feeling the surface texture
between finger and thumb.
•
IF THE O-RING IS DAMAGED OR
SUSPECTED OF BEING DAMAGED, DISCARD
IT IMMEDIATELY
.
A spare O-ring is
supplied with your housing, or a replacement O-ring can be ordered from 10 BAR. If the O-ring is
contaminated or suspected of being contaminated, clean it with a cotton cloth that is free of all
chemicals or contamination. After cleaning inspect the O-ring again.
