The housing is sealed with pairs of O-rings,
which require meticulous care. To maintain
a watertight seal, the O-ring and its mating
surfaces must be clean, free of foreign
material, and lubricated with silicone
grease.
The following maintenance procedure
should be performed:
Clean all old silicone grease from O-ring
and mating surfaces using paper towels.
Inspect O-ring for foreign material (sand,
seaweed, hair, etc.), cracks, cuts, soft
spots, or deformities. Replace O-ring if
damaged. Inspect mating surfaces for
scratches, rough spots, dents, or cracks.
S
ILICA DRYING BAGS MUST BE REPLACED
IF THE HOUSING IS OPENED FOR
MAINTENANCE
.
Apply thin, even coat of silicone grease to
O-ring using fingers. Install the O-rings.
Immediately wash your hands in a mild
soap and dry before handling other
components.

The camera system is designed for
continuous underwater operation and can
operate safely for months without removal.
The placement and conditions underwater
will dictate the frequency and extent of
surface growth and contamination and will
dictate how often the system may need to
be removed for maintenance.
The glass dome can be rubbed with a
nylon cloth to remove algae growth.
Particulate matter that may settle on the
dome can be dusted by hand. If the
housing shows excessive accumulation of
algae growth, it should be detached from
the cables and brought to the surface for a
more thorough cleaning.

The OceanCam has been designed for
continuous underwater operations and
could operate in place for as much as six
months. Generally, it is advisable to
remove the camera every 2-3 months for a
thorough cleaning.
A thin coating of silicone grease on the
acrylic surfaces is somewhat effective in
reducing algae growth.
The frequency of underwater maintenance
will depend on other maintenance
practices that may lead to a build up of
sediment on the dome. The dome should
be “dusted” as often as possible and at
least at the conclusion of other cleaning
activities.
