4.5 Maintaining the O-ring Seal:

If the main body to lid O-ring is not installed, install the O-ring before diving. This is

the only user serviceable O-ring. Its c are and maintenance are critical to the watertight

integrity of the housing. The O-ring should be replaced at the service interval (see section on

service). If the O-ring is contaminated, or not already installed, inspect, grease and install the

O-ring according to the following guidelines.

4.6 Inspection, cleaning and re-instillation of the O-ring

Tools:

A soft cotton bud or sponge applicator, make sure these are free of all chemicals or

contamination such as loose fibers, and the tube of silicone grease supplied with the housing

are required. Note other types of silicone grease specifically for use with underwater camera

equipment can usually also be used. It is advised to carry out the following procedure on a

firm clean level surface, (e.g. at a table), to prevent skidding especially useful to have when

diving from a boat.

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-ring did not become contaminated. As a

rule of thumb 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, 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.
