Installation
These safety instructions are limited to pneumatic actuators which are operating using air or nitrogen (inert gas). If the
application requires use of a flammable or hazardous gas, you must contact your
Emerson sales office
or Local
Business Partner for assistance.
WARNING
To avoid personal injury and property damage caused by bursting of parts and to avoid parts damage, malfunction of
control valve, or loss of control of the process caused by excessive pressure, do not exceed the maximum pressures or
temperatures for this actuator, as given in the applicable product literature or on the nameplate. Use pressure‐limiting or
pressure‐relieving devices to prevent the actuator pressure from exceeding specified limits. If you cannot determine the
limits for this product, contact your Emerson Automation Solutions sales office before proceeding.
D
To avoid personal injury, always wear protective gloves, clothing, and eyewear when performing any installation
operations.
D
Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
D
If hoisting the actuator, use a nylon sling to protect the surfaces. Carefully position the sling to prevent damage to the
actuator tubing and any accessories. Also, take care to prevent people from being injured in case the hoist or rigging
might slip. Be sure to use adequately sized hoists and chains or slings to handle the assembly.
D
If installing into an existing application, also refer to the WARNING in the Maintenance section.
Operation
WARNING
When moving the actuator stem or shaft with loading pressure applied, use caution to keep hands and tools out of the
actuator travel path. Personal injury and property damage is possible if something is caught between the actuator stem
and other control valve assembly parts.
Maintenance
WARNING
Avoid personal injury or property damage from sudden release of process pressure or uncontrolled movement of parts.
Before performing any maintenance operations:
D
Do not remove the actuator while the valve is pressurized.
D
Always wear protective gloves, clothing, and eyewear.
D
Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the
actuator cannot suddenly open or close the valve.
