How to Use This ManualHow to Use This ManualTHIS MANUAL APPLIES TO SST 350, 500, AND SST 700 SINGLE STAGETURBINES.This instruction manual contains installation, operation, and maintenanceinstructions for the Dresser-Rand Turbine identified on the Turbine Data Sheetincluded with this manual. It should be reviewed thoroughly by the user beforeattempting to install and operate the turbine, and should be kept in a locationconvenient to the user for ready reference during operation and maintenance.WARNINGA complete reading of this manual by personnel in contact withthe steam turbine is essential to safety. INCORRECTINSTALLATION, OPERATION, MAINTENANCE, OR PARTSREPLACEMENT CAN RESULT IN INJURY TO PERSONNEL,AND DAMAGE TO THE TURBINE, DRIVEN MACHINERY,AND PLANT.The Instruction Manual consists of 15 sections, as listed in the table of contents.Each section is further broken down into subsections.This is a general instruction manual, describing a standard ring oiled or pressurelubricated turbine with hydraulic or electronic governors. The description andillustrations contained herein may differ in minor details from the unit actuallysupplied. All general installation, operation, and maintenance procedures areapplicable.For turbines supplied with options such as forced or circulating lubricationsystems, alternative speed control systems, accessories, instrumentation, speedreducers or other special configurations, refer to the appropriate accessory manualsand turbine certified drawing package included in Appendix A and Appendix Bfollowing this manual.March 2011Revision A1

How To Use This ManualSST Turbine Instruction ManualWARNINGThroughout this manual, it is assumed that the motive flow applied atthe turbine inlet is high-pressure steam. Therefore, the word “steam”is used in reference to various aspects of turbine installation,operation, and maintenance. For some specialized applications, highpressure gasses such as Freon, natural gas, or other vapors mayprovide the motive flow. In these cases, it can generally be assumedthat the name of the gas in use may be used to replace the word“steam.” The user of the equipment must address all hazardsassociated with the nature of the specific motive flow in use with theturbine. If flammable or toxic gasses are used as the motive fluid or ifoil vapor could be emitted, the user/installer must pipe leak-offs anddrains to a safe location. Explosive gas mixtures must not be used asthe motive fluid.The instructions contained in this manual do not attempt to cover all details, nordoes it provide for every possible contingency to be met in connection withinstallation, operation, or maintenance of the supplied equipment.The supplying of instructions does not imply, in any manner, that Dresser-Randaccepts liability for work carried out by a customer or contractor personnel.Liability is limited to and as stated in our Terms and Conditions of Sale.Should further information be desired, or should particular problems arise, thematter should be referred to Dresser-Rand.This manual is intended for use by personnel with a general knowledge of properoperation and maintenance of steam turbines. Special training or the assistance ofa trained Dresser-Rand service representative is suggested for personnel with lessthan a general working knowledge of this type of equipment.All inquiries regarding installation, operation, maintenance, spare parts, or serviceshould be directed to your Dresser-Rand manufacturer’s representative, or to:Dresser-RandSteam Turbine Business fer to Section M, Replacement Parts/Factory Service, for information on how torequest factory service or order replacement parts.2Revision A SSTTurbineInstruction

SST Turbine Instruction ManualEU ComplianceEU ComplianceThe following warning and notes apply only to turbines for whichcompliance with European Union Directives has been specified.NOTEIf there is a CE mark on this turbine nameplate it indicatescompliance with the ATEX Directive. Machinery DirectiveCompliance and Machinery Directive CE marking of the turbineand driven equipment is the responsibility of the assembler orinstaller. See the Machinery Directive Declaration ofIncorporationWARNINGATEX Certified turbines will have a mark –c C X on the turbinenameplate. This indicates that the turbine casing temperaturewill become that of the motive fluid (steam or gas) inlettemperature, this may exceed the ignition temperature of somegasses. See the ATEX Directive Risk Assessment SummaryList accompanying the ATEX Declaration of Conformance.NOTERefer to the Machinery Directive – List of Residual Risks andATEX Directive-Risk Assessment Summary List for warningsrelated to EU Compliance.Additional cautions and warnings are located throughout thismanual and in the Safety Precautions Section.SST Turbine Instruction ManualRevision A3
