Maintenance of the Gasket Seal
Each housing is individually inspected and hydrostatically tested in the factory. The design of the
compression gasket seal is among the most reliable in the industry and the watertight integrity is
excellent. This special gasket design provides a perfect seal even if there is any movement between
the body and lid due to change of ambient pressure.
With this in mind…
The gasket seal is the only barrier between the water outside and the air space within the flash. It is an
effective barrier only if the seal is properly maintained. The gasket seal should be inspected before
every dive. The following information is provided for your guidance in using and maintaining the
gasket seal.
Maintaining the gasket Seal
If the main body to lid gasket is not installed, install the gasket before diving. This is the only user
serviceable gasket. Its care and maintenance is critical to the watertight integrity of the housing. The
gasket should be replaced at the proper service interval (see Section on Service). If the gasket is
contaminated, or not already installed, inspect and install the gasket according to the following
guidelines.
Guidelines for Inspection, Cleaning and Re-Instillation of the Gasket
Materials Needed:
You will require a soft cotton cloth or q-tip. Make sure these are free of all chemicals or
contamination such as loose fibers You can moisten the cotton or cloth and wipe the surface of gasket
clean—no silicon grease or lubricant is necessary It is advised to carry out the following procedure on
a firm clean level surface, e.g. at a table), to prevent skidding. This is especially useful if you are
doing this maintenance from your diving boat as it moves.
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. The housing may be
required to be opened between dives, to replace memory card or recharge the batteries. Before
opening, make sure the outside of the housing is thoroughly toweled dry. 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, etc. has fallen onto the
gasket recess. As a precaution we recommend visually inspecting the gasket every time the lid is
opened and before it is sealed.
