SECTION 5: MAINTENANCE 5-16
General Cleaning and Inspection
Whenever the Unit has been recovered from a deployment, the Unit should be cleaned and rinsed with
fresh water to avoid salt buildup and deterioration of mechanical parts. A visual check of the Housing and
release mechanism should be performed to detect any signs of damage, excessive wear, corrosion, etc.
Inspection Particulars
• Check the condition of the Release Arm
• Check for corrosion of the Purge Plug
o Inspect and replace the two O-Rings on the Purge Port Plug, as needed
• Check and replace if needed all O-rings
o Each End Cap has three O-rings: a Gland O-ring, a flat, back-up O-ring, and a face seal O-
ring. The inner O-ring is the flat backup O-ring, the curved surface should be facing the
outer gland O-ring and toward the endcap. The Face Seal O-Ring is independent and
always by itself. Both O-rings need to be in the correct position and properly lubricated
to ensure water tight integrity.
• Check and replace the (8) O-Rings mentioned above, if needed.
