CARE AND MAINTENANCE
Of the housing:
After each and every salt water dive, your housing system should be soaked or rinsed in fresh water.
The housing system should soak in fresh water for at least 30 minutes. During this soaking period
reach into the water and operate all the controls several times.
Be sure to remove the housing’s main o-ring and clean it after every use. Refer to Maintenance: Of
the O-rings. To ensure that the hand grips won’t fuse on to the housing due to the exposure to salt
water, it is also a good practice to occasionally remove the hand grips. Clean and lubricate the bolts
with a small amount of WD-40.
WARNING:
Use WD-40 carefully, sparingly and only on metal to metal surfaces. WD-40 can damage
the acrylic on the ports, the optical surfaces on lens as well as the O-rings.
Of the Ports:
Care should be taken with the Dome Port and Macro Port to avoid scratches on the lens surface. The
acrylic port is softer than glass so minor exterior scratches are often unavoidable. However, since
the indices of refraction for acrylic and water are almost equal the scratches will not seriously impair
image quality. Internal scratches (air side) must be avoided as they do not fill in with water and will
affect the quality of the image.
Clean the dome using only products recommended for cleaning acrylic such as Mirror glaze #17
Professional Plastic Cleaner and a soft lint free cloth. Dust on the interior surfaces of the port can be
removed with a soft camel hair brush or a blower brush. Caution must be taken when using aerosol
devices as not to spray the lens material with the liquid propellant as this may seriously affect the opti-
cal properties of the port. The ports should be removed and serviced after every dive.
Of the Latches:
The two latches of the AQUATICA A40D are designed to have a locking action to prevent accidental
opening. Always ensure that the locking mechanism is secure. Watch for the build-up of corrosion
or salt residue around the latches. This will appear as a white material. Lubricate the latches with a
small amount of WD-40 to remove the corrosion or salt residue build-up.
Of the O-Rings:
The O-rings that need to be maintained on a regular basis are the main housing O-ring and the O-ring
on the lens port.
The main O-ring should be cleaned on a daily basis and the port O-ring should be cleaned daily or
each time the port is changed.
