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, 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 if necessary.
Procedure:
• 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 has no
sharp edges). Alternatively use the flats of the thumbs to gently stretch the O-ring on
two faces (Fig. 4) 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 or
sponge applicator.
• 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 obtained from 10 BAR. If the O-ring is contaminated or suspected of being
contaminated, clean it with a cotton cloth that is free of loose fiber, chemicals or
contamination. After cleaning inspect the O-ring again.
• Once the O-ring has been inspected and verified fit for use, apply a SMALL amount of
silicone grease to the O-ring. The silicone grease must be evenly distributed round the
O-ring.
• Replace the O-ring into the groove; run a finger round the O-ring, to make sure it is
snugly seated in the groove.
