- It’s a good practice to rinse the housing with fresh water, ensuring it is properly
closed, after each salt water use. Then dry it accurately. Run water in the greatest
stagnation points of salt water as perimeter rings, caps, lens, eyepiece, command
buttons and levers.
WARNING: it is advisable to operate the control buttons during the rinse, so as to
remove any residual salt within that, in the long run, it could lead to blockage.
- Before removing the rear cap, make sure that the housing is completely dry.
- We recommend to remove the port after every use to avoid its blockage.
- It’s a good practice to clean and grease the O-ring with silicone grease without
exagerating. It is recommended to use special silicone grease for O-rings. If using
unsuitable grease or spray, you may experience O-ring swelling or their expansion,
affecting the seal. You need to grease the O-ring away from towels, bathrobes,
tablecloths etc. or places of stagnant dust, because the grease protects the O-ring,
but attracts various lightweight materials such as fur, hair, fibres, grains of salt,
sand, etc. These particles are difficult to see because of the presence of grease. You
must therefore pay particular attention to the cleanliness of the O-ring, otherwise
you could create flooding, that would certainly have been avoided with a correct
maintenance. Replace the main O-ring annually.
- When you do not in use the housing for a long time you must to remove the O-rings
and sprinkle all the external metal parts with a light coat of vaseline oil.
N.B.
*
Never use Vaseline oil to lubricate the O-rings, use only silicone grease.
We recommend the use of Isotta products.
- Do not use solvents, thinners, or alcohol to clean the port, the eye-piece or the monitor.
- Treat the surface of the lens port like a camera lens. After use, rinse and gently dry
the outside lens port to avoid water spotting. To clean, use a mild soap solution
or lens cleaner. Do not rinse the inside of the Port. Never use alcohol or window
cleaner on the Lens Port.
CARE AND MAINTENANCE
It is recommended that you ship the housing to our distributor or to Isotecnic
factory for a complete overhaul every 2 years or after 500 dives.
