Points of Attention Before Removal from the System
- Swagelok recommends removing the regulator from the system for servicing and maintenance.
- Follow all local system safety and maintenance procedures when removing the regulator.
WARNING
Before removing a regulator from the system, to avoid personal injury, you must:
•
Depressurize the system.
•
Purge the system to remove any residual system media left in the regulator.
•
Always vent to a safe environment away from people and ensure there is adequate
ventilation.
CAUTION
Check if the process media is hazardous or toxic. If required, take the necessary safety
precautions to ensure a safe workspace and your personal safety.
CAUTION
The product can be hot or cold, depending on the environmental temperature and the process
media temperature. Take the necessary precautions before operating or touching the product.
Removal from the System
1. Isolate the regulator from all pressure sources by closing all appropriate upstream valves in the system.
2. With the regulator set to the open position (i.e. set screw backed off fully counterclockwise) , open all
appropriate downstream valves to allow pressure to vent from the regulator.
WARNING
Ensure all pressure on the inlet and outlet has been fully vented. The accidental release of
residual trapped pressure can cause serious personal injury.
3. Disconnect and remove the regulator from the system.
