The Man From Atlantis S01E09 part 1 of 2

Our hero (Patrick Duffy) is subdued with knockout gas and then tied to a chair. Weakened from being out of the water too long, he manages to make a special sound that triggers a sprinkler, rewetting him and restoring his strength so he can easily break the bonds holding him.
