    1.1 UsingThe following instructions are designedto assist in unpacking, installing andperforming maintenance as required onFLOWSERVE products. Product usersand maintenance personnel shouldthoroughly review this bulletin prior toinstalling, operating or performing anymaintenance.

    1. General information

    1.2 Terms concerning safetyThe safety terms DANGER,WARNING, CAUTION and NOTEare used in these instructions tohighlight particular dangers and/or to provide additional informa-tion on aspects that may not bereadily apparent.

    DANGER: indicates that death,severe personal injury and/orsubstantial property damage willoccur if proper precautions are nottaken.

    WARNING: indicates that death,severe personal injury and/orsubstantial property damage canoccur if proper precautions are nottaken.

    CAUTION: indicates that minorpersonal injury and/or propertydamage can occur if properprecautions are not taken.

    In most cases FLOWSERVE valves,actuators and accessories are designedfor specific applications (e.g. with regardto medium, pressure, temperature). Forthis reason they should not be used inother applications without first contactingthe manufacturer.

    NOTE: indicates and providesadditional technical information,which may not be very obviouseven to qualified personnel.

    Compliance with other, not particularlyemphasised notes, with regard to trans-port, assembly, operationandmaintenance and with regard to technicaldocumentation (e.g. in the operatinginstruction, product documentation or onthe product itself) is essential, in orderto avoid faults, which in themselves mightdirectly or indirectly cause severe per-sonal injury or property damage.

    1.3 Protective clothingFLOWSERVE products are often usedin problematic applications (e.g.extremely high pressures, dangerous,toxic or corrosive mediums). In particularvalves with bellows seals point to suchapplications. When performing service,inspection or repair operations alwaysensure, that the valve and actuator aredepressurised and that the valve hasbeen cleaned and is free from harmfulsubstances. In such cases pay particularattention to personal protection(protective clothing, gloves, glasses etc.).

    1.4 Qualified personnelQualified personnel are people who, onaccount of their training, experience andinstruction and their knowledge of rele-vant standards, specifications, accidentprevention regulations and operatingconditions, have been authorised bythose responsible for the safety of theplant to perform the necessary work andwho can recognise and avoid possibledangers.

    1.5 InstallationDANGER: Before installationcheck the order-no, serial-no. and/or the tag-no. to ensure that thevalve/actuator is correct for theintended application.Do not insulate extensions that areprovided for hot or cold services.

    Pipelines must be correctlyaligned to ensure that the valve isnot fitted under tension.

    Fire protection must be providedby the user.

    1.6 Spare partsUse only FLOWSERVE original spareparts. FLOWSERVE cannot acceptresponsibility for any damages that occurfrom using spare parts or fasteningmaterials from other manufactures. IfFLOWSERVE products (especiallysealing materials) have been on store forlonger periods check these for corrosionor deterioration before using theseproducts. Fire protection forFLOWSERVE products must beprovided by the end user.

    1.7 Service / repairTo avoid possible injury to personnel ordamage to products, safety terms mustbe strictly adhered to. Modifying thisproduct, substituting nonfactory parts, orusing maintenance procedures otherthan outlined in this instruction coulddrastically affect performance and behazardous to personnel and equipment,and may void existing warranties.Between actuator and valve there aremoving parts. To avoid injuryFLOWSERVE provides pinch-point-protection in the form of cover plates,especially where side-mounted position-ers are fitted. If these plates are remo-ved for inspection, service or repair spe-cial attention is required. After completingwork the cover plates must be refitted.

    Apart from the operating instructions andthe obligatory accident preventiondirectives valid in the country of use, allrecognised regulations for safety andgood engineering practices must befollowed.
