2 Refer to separate instruction manuals for information regarding thecontrol valve, actuator, and not install, operate, or maintain C1 pressure Controllers and Transmitters without first being fully trained andqualified in valve, actuator, and accessory installation, operation, and maintenance. To avoid personal injury andproperty damage, it is important to carefully read, understand, and follow all the contents of this manual, includingall safety cautions and warnings. If you have any questions about these instructions, contact your Emerson sales officeor Local Business Partner before C1 Pneumatic pressure Controllers and Transmitters use a bellows or Bourdon tube sensing element to sense thegauge pressure, vacuum, compound pressure, or differential pressure of a liquid or gas.
