To minimize the possibility of separator element
rupture, it is important that ONLY replacement
elements identified with the Sullair name, logo
and appropriate part number be used and that
substituted elements not be used, due to the fact
that such elements may have inadequate or
questionable working pressure ratings.
Relieve all pressure from the sump tank and all
compressor lines.

cleanliness it is important that ONLY a replace-
ment fluid filter identified with the Sullair name,
