Page 5: Safety Instructions And Measures
In case operators intend to use the devices in other applications or condi- tions than specified, contact SAMSON. SAMSON does not assume any liability for damage resulting from the failure to use the de- vice for its intended purpose or for damage caused by external forces or any other external factors. - Page 6 Î Wear hearing protection when working near the valve. Î Check with the plant operator for details on further protective equipment. Revisions and other modifications Revisions, conversions or other modifications of the product are not authorized by SAMSON. They are performed at the user's own risk and may lead to safety hazards, for example. Fur- thermore, the product may no longer meet the requirements for its intended use.
- Page 7 Safety instructions and measures Referenced standards and regulations The devices comply with the requirements of the European Pressure Equipment Directive 2014/68/EU. Devices with a CE marking have an EU declaration of conformity, which in- cludes information about the applied conformity assessment procedure. This EU declaration of conformity is included in the Appendix of these instructions (see section 9.3). Non-electric valve versions whose bodies are not lined with an insulating material coating do not have their own potential ignition source according to the risk assessment stipulated in EN 13463-1: 2009, section 5.2, even in the rare incident of an operating fault. Therefore, such valve versions do not fall within the scope of Directive 2014/34/EU.

Page 8: Notes On Possible Severe Personal Injury
Safety instructions and measures 1.1 Notes on possible severe personal injury DANGER Risk of bursting in pressure equipment. Valves and pipelines are pressure equipment. Improper opening can lead to valve components bursting. Î Before starting any work on the valve, depressurize all plant sections concerned as well as the valve. Î Drain the process medium from all the plant sections concerned as well as the valve. -
Page 9: Notes On Possible Property Damage
Safety instructions and measures Damage to health relating to the REACH regulation. If a SAMSON device contains a substance which is listed as being a substance of very high concern on the candidate list of the REACH regulation, this circumstance is indi- cated on the SAMSON delivery note. - Page 10 Safety instructions and measures Risk of damage to the valve or safety temperature limiter due to excessively high or low tightening torques. The connection between valve and safety temperature limiter must be tightened with a certain tightening torque. Excessively tightened torques lead to parts wearing out quicker. Parts that are too loose may cause leakage.
