Care and maintenance
Rinse the O-ring with fresh water and dry it with a clean lint free cloth.
Clean the O-ring groove (the channel where the O-ring sits) with a
cotton swab. Make sure to remove any lint the cotton swab may leave
behind.
Wipe the matching sealing surface part of the housing with a clean
lint-free cloth.
Lubricate the O-ring with a thin layer of Aquatica O-ring lubricant (#
19213) until it appears to be smooth and shiny.
Do not over lubricate
.
Use just enough lubricant so the O-ring will pull smoothly through
your fingers. Excessive amounts of grease will only attract and trap dirt
onto the O-ring.
Confirm that the Port and extension ring O-rings are properly and
evenly seated in their O-ring groove.
To reinstall the clean and lubricated main O-ring of the housing:
Place the entire O-ring over the groove and start by pushing
the O-ring in at each corner.
Push the O-ring at each side to distribute it evenly across the
surface before finally working in the rest of the O-ring.
Never start at one end and work your way around the O-ring.
This creates uneven tension on the O-ring which may cause
the O-ring to stretch.
Note:
When changing ports or O-rings, a simple seal test without the
camera inside should be performed. Strapping a weight to the
housing and lowering the unit to a depth of 30 to 50 feet of water
for at least 10 minutes will assure you that you have a proper seat
of the new port or O-ring. This test,
though time consuming and
often considered unnecessary, may save your camera equipment
from irreparable water damage.
