* Outlet pressure can be adjusted to pressures in excess of, and less than, those
specified. Do not use these units to control pressures outside of the specified
ranges.
** Units with 250 psig (17 bar) outlet pressure range are available only with the T-
bar adjustment; therefore substitute T at the 7th digit and S at the 12th position.
