Page 7: Notes On Possible Severe Personal Injury
In the installed state, the spring in the operating element is preloaded. Incorrect dis- mantling will release a high amount of energy, which may lead to serious injury. Î Do not dismantle the device. Î Contact SAMSON's After-sales Service for support concerning maintenance or re- pair work or when malfunctions or defects arise (see section 9). 1.2 Notes on possible personal injury WARNING Risk of personal injury due to residual process medium in the valve. -
Page 8: Notes On Possible Property Damage
Risk of leakage and valve damage due to excessively high or low tightening torques. Observe the specified torques when tightening valve components. Excessive tightening torques lead to parts wearing out more quickly. Parts that are too loose may cause leakage. Î Observe the specified tightening torques. Risk of device damage due to incorrectly attached lifting equipment. Î Do not attach lifting equipment to mounting parts (e.g. capillary tube). EB 2519 EN... -
