Installation, Mating and Maintenance
Mating Procedure
(1) Inspect contacts and O-rings. (2) Apply silicone grease to O-rings. (3) Align MP to FS and push straight. (4) Install locking sleeve immediately. (5) IR test before deployment.
Deck Handling
Install dummy plugs before water entry. Rinse with fresh water after seawater exposure. Inspect rubber body after every dive.
Storage
Store with dummy plugs, dry and UV-shaded. Replace O-rings every 2 years.
