REASSEMBLY PROCEDURE
NOTE: Prior to Reassembly, it is necessary to inspect all
parts, both new and those that are being reused. Check to
ensure that O-rings are clean and supple, and that every part
and component has been thoroughly cleaned and dried.
WARNING: Use only genuine Oceanic parts, subassem-
blies, and components whenever assembling Oceanic prod-
ucts. DO NOT attempt to substitute an Oceanic part with
another manufacturer’s, regardless of any similarity in shape,
size, or appearance. Doing so may render the product
unsafe, and could result in serious injury or death of the user.
