WARNING
!
Avoid personal injury or property damage from sudden release of process pressure or
bursting of parts. Before proceeding with any Installation procedures:
• Always wear protective clothing, gloves and eyewear to prevent personal injury or
property damage.
• Do not remove the actuator from the valve while the valve is still pressurized.
• 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.
• Use bypass valves or completely shut off the process to isolate the valve from
process pressure. Relieve process pressure on both sides of the valve.
• Use lock‐out procedures to be sure that the above measures stay in effect while you
work on the equipment.
• Check with your process or safety engineer for any additional measures that must
be taken to protect against process media.
• Vent the pneumatic actuator loading pressure and relieve any actuator spring
precompression so the actuator is not applying force to the valve stem; this will
allow for the safe removal of the stem connector.
WARNING
!
To avoid static discharge from the plastic portion of the cover when flammable
gases or dust are present, do not rub or clean the cover with solvents. To do so could
result in a spark that may cause the flammable gases or dust to explode, resulting in
personal injury or property damage. Clean with a mild detergent and water only.
NOTICE
Do not use sealing tape on pneumatic connections. This instrument contains small
passages that may become obstructed by detached sealing tape. Thread sealant
paste should be used to seal and lubricate pneumatic threaded connections.
