In case operators intend to use the regulators in other applications or conditions 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
Hazards resulting from the special working conditions at the installation site of the regulator must be identified in a risk assessment and prevented through the corresponding safety in- structions drawn up by the operator. We also recommend checking the hazards posed by the process medium being used (e.g. u GESTIS (CLP) hazardous substances database). Î Observe safety measures for handling the device as well as fire prevention and explosion protection measures. Safety features The Type 2479/2430 Regulator does not have any special safety features. 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. EB 3132-3 EN...

This also applies to the start-up and shutdown procedures. Start-up and shutdown procedures fall within the scope of the operator's duties and, as such, are not part of these mounting and operating instructions. SAMSON is unable to make any statements about these procedures since the operative details (e.g. differential pressures and temperatures) vary in each individual case and are only known to the operator.

Safety instructions and measures 1.2 Notes on possible personal injury WARNING Risk of personal injury through incorrect operation, use or installation as a result of information on the regulator being illegible. Over time, markings, labels and nameplates on the regulator may become covered with dirt or become illegible in some other way. As a result, hazards may go unno- ticed and the necessary instructions not followed.

Safety instructions and measures WARNING 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. Î Information on safe use of the part affected u www.samsongroup.com/en/ about-samson/material-compliance/reach-regulation/ Risk of personal injury due to residual process medium in the regulator.
The lubricants to be used depend on the regulator material. Unsuitable lubricants may corrode and damage surfaces. Î Only use lubricants approved by SAMSON. When in doubt, consult SAMSON. Risk of leakage and regulator damage due to excessively high or low tightening torques.
