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.

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.

especially when diving from a boat.

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.
