DANGER: indicates that death, severe personal injury and/or substantial property damage will occur if proper precautions are not taken.
WARNING: indicates that death, severe personal injury and/or substantial property damage can occur if proper precautions are not taken.
CAUTION:indicates that minor personal injury and/or property damage can occur if proper precautions are not taken.
NOTE: indicates and provides additional technical information, which may not be very obvious even to qualified personnel.
Compliance with other, not particularly emphasisednotes,withregardtotransport,assembly,operationandmaintenanceandwithregardtotechnicaldocumentation(e.g.intheoperatinginstruction,productdocumentationorontheproductitself)isessential,inordertoavoidfaults,whichinthemselvesmightdirectlyorindirectlycauseseverepersonalinjuryorpropertydamage.
1.3 Protective clothing
FLOWSERVE products are often used in problematicapplications(e.g.extremelyhighpressures,dangerous,toxicorcorrosivemediums).Inparticularvalveswithbellows seals point to such applications. When per-formingservice,inspectionorrepairoperationsalwaysensure,thatthevalveandactuatoraredepressurisedandthatthevalvehasbeencleanedandisfreefromharmfulsubstances. In such casespayparticular attention topersonalprotection(protectiveclothing,gloves,glassesetc.).

1.7 Service / repair
To avoid possible injury to personnel or damage toproducts, safety terms must be strictly adhered to.Modifying thisproduct,substitutingnonfactoryparts,orusingmaintenanceproceduresother thanoutlinedinthisinstructioncoulddrasticallyaffectperformanceandbehazardoustopersonnelandequipment,andmayvoid existing warranties. Between actuator and valvethere are moving parts. To avoid injury FLOWSERVEprovides pinch-point-protection in the form of coverplates,especiallywhereside-mountedpositionersarefitted.Iftheseplatesareremovedforinspection,serviceorrepairspecialattentionisrequired.Aftercompletingworkthecoverplatesmustberefitted.
Apartfromtheoperatinginstructionsandtheobligatoryaccident prevention directives valid in the country ofuse, all recognised regulations for safety and goodengineeringpracticesmustbefollowed.
WARNING: Before products are returned to FLOWSERVE for repair or service FLOWSERVE must be provided with a certificate which confirms that the product has been decontaminated and is clean. FLOWSERVE will not accept deliveries if a certificate has not been pro-vided (a form can be obtained from FLOWSERVE).
1.8 Storage
InmostcasesFLOWSERVEproductsaremanufacturedfromstainlesssteel.Productsnotmanufacturedfromstainlesssteelareprovidedwithanepoxyresincoating.ThismeansthatFLOWSERVEproductsarewellprotectedfrom corrosion. Nevertheless FLOWSERVE productsmustbestoredadequatelyinaclean,dryenvironment.Plastic caps are fitted to protect the flange faces toprevent the ingress of foreign materials. These capsshouldnotberemoveduntilthevalveisactuallymountedintothesystem.
1.9 Valve and actuator variations
Theseinstructionscannotclaimtocoveralldetailsofall possible product variations, nor can they provideinformationforeverypossibleexampleofinstallation,operation or maintenance. This means that theinstructions normally include only the directions tobe followed by qualified personal where the productisbeingused for isdefinedpurpose.
