6 MAINTENANCE
Maintenance of the camera is typically limited to cleaning, and maintenance of the O-ring
seals on the window and rear end plate. The acrylic window should only be cleaned with a
commercial lens cleaner or with a mild soap and water. Use only a soft cloth or lens tissue
to avoid scratching the surfaces.
Anytime the housing is removed the O-rings should be carefully inspected for cuts, tears, or
any other damage and replaced if necessary. The new O-ring should be given a light
coating of silicone grease or other O-ring lubricant before re-assembly.
On the internal camera assembly, ensure that all electrical connectors are correctly fitted
and all cabling is secured.
All threads should be carefully inspected for burrs or early signs of galling. Small areas of
damaged threads may be polished to remove any offending material. The threads should
then be completely cleaned and coated with a waterproof lubricant. When reassembling
the camera, be aware of any grinding or dragging that might signify thread damage.
As the camera is being re-assembled just before the camera is sealed in the housing,
blowing dry air or nitrogen into the housing is highly recommended, to avoid condensation
on the inside surfaces, especially the front port. This is especially important if the camera
is being sealed in a humid environment. Excess humidity in the housing will normally result
in fogging of the window and may cause eventual damage to the camera electronics
through corrosion.
