Î Check with the plant operator for details on further protective equipment. Revisions and other modifications Revisions, conversions or other modifications to 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.
Safety instructions and measures Referenced standards and regulations The devices comply with the requirements of the European Pressure Equipment Directive 2014/68/EU. Referenced documentation The mounting and operating instructions of the mounted valve accessories (e.g. u EB 8357 for Type 4740 Limit Switch) apply in addition to these mounting and operating instructions. 1.1 Notes on possible severe personal injury DANGER Risk of bursting in pressure equipment.
Safety instructions and measures WARNING Risk of personal injury due to residual process medium in the valve. While working on the valve, residual process medium can escape and, depending on its properties, may lead to personal injury, e.g. (chemical) burns. Î...
