Care and maintenance
With basic care and a regular maintenance schedule, your Aquatica housing will provide years
of enjoyment and satisfaction in producing spectacular underwater images. Please follow all
undermentioned care and maintenance instructions.
Housing components
After every salt water dive, soak and/or rinse your housing system in fresh water. It should
soak for a minimum of 30 minutes. Operate all the controls several times, while soaking, to
dislodge any trapped salt water residues.
Periodically remove the hand grips for storage and transportation to avoid having the thread
of the attachment bolts fuse on to the housing. Unscrew, clean and lubricate the bolts with a
small amount of WD-40 or Zinc-based lubricant.
WARNING:
Use WD-40 or any lubricant carefully, sparingly and only on metal to metal
surfaces. WD-40 or other petroleum-based lubricants can damage the acrylic on
the ports, the optical surfaces of a lens or O-rings.
Sacrificial anodes
Two anodes are attached to the bottom parts of the housing to prevent galvanic corrosion
due to electrolysis. As time goes and depending on use, they will deteriorate and need
replacement. Contact your dealer to order replacement anodes (#19220).
O-rings
When replacing the main seal O-ring, place the entire O-ring over the O-ring groove and start
by pushing the O-ring in the corners. Work your way around the O-ring making sure it is snugly
sitting in the groove. Avoid going solely in one direction as doing so will stretch the O-ring
material and possibly prevent it from properly seating.
When working your housing or port O-rings, please follow these instructions:
Never use a sharp instrument when removing an O-ring as this may damage the
sealing surface of the groove or the O-ring itself. A dedicated O-ring tool, a dull
pointed object or the edge of a credit card usually works well.
Once removed, the O-ring should be inspected for damage. Carefully check that it
is free of nicks or cuts and that it retains its original round profile. O-rings that
appear to be damaged should be immediately replaced with new ones.
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.
