Installation

Nuclear Qualified

Pressure Switch

with Terminal Block

General Instructions

The vent connection must be plugged or vented to dry atmosphere as required by
application requirements. Test Data Sheet SOR form #716 is supplied for each serial
number and provides switch performance data in the vented and plugged condition.

Failure to mount the housing on a  at mounting surface may result in
torsional forces on the housing that could cause false trips or render the
pressure switch inoperative.

Process 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.

Design and specifications are subject to change without notice.
