4. Set up Instructions
4.1 Special note on responsibility for watertight integrity
Each housing is individually inspected and hydrostatically tested in the factory. The design of the main piston
O-ring seal is among the most reliable in the industry and the watertight integrity is excellent. This special
O-ring design provides a perfect seal even if there is any movement between the body and lid due to change
of ambient pressure. However please note that responsibility for ensuring the integrity of the watertight seal
lies entirely with the user. 10BAR accepts no liability for damage to, or loss of any equipment used with, or
placed inside the housing. Users are highly recommended to carry out in-water test of the housings without
installing of the camera for their first dive, after change of new ports or alternation of any new configuration.
The test can be carried out by lowering the housing with ballast to the working depth or dive down to the safe
diving range.
The O-ring seal is the main barrier between the water outside and the air space within the camera.
It is an effective barrier only if the seal is properly maintained. The O-ring seal should be inspected
before every dive. The following information is provided for your guidance in using and
maintaining the O-ring seal.
4.2 Maintaining the O-ring Seal
If the main body to lid O-rings are not installed, install the
O-rings before diving. Their care and maintenance are
critical to the watertight integrity of the housing. If the
O-rings are contaminated, or not already installed; inspect,
grease and install the O-rings according to the following
guidelines.
4.3 Inspection, cleaning and re-instillation of the O-rings
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. 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 when diving from a boat.
