Process Connection
Electrical Connection
Securely connect process line to pressure port using two wrenches: one to hold hex flats on
pressure port, the other to tighten process pipe or tube fitting.
Be certain the process connection is tightened and positioned so bending
and torsional forces imposed on pressure switch are minimal. Use care
not to loosen pressure port from body or body from housing.
Electrical connections are
marked on the insulation of
the wire leads. Conduit should
be installed without applying
