Product Safety GuidelinesWARNING! The improper selection and/or use and/orimproper installation and/or maintenance of accumulatorsand related accessories can result in failure and/or deathand/or personal injury and/or property damage.Prior to the selection or installation or use of any TobulAccumulator or related accessories, it is important that theuser read, understand and follow all safety information.42OVERVIEWDue to the wide variety of accumulator (hereafter referredto as “products”) applications and operating conditions,Tobul Accumulator, Inc. does not warrant any particularproduct or products as suitable for any specific application.This safety guide does not consider and/or attempt to analyzeall technical information and hydraulic system parameterswhich must be considered in selection of products.Each user, through their own analysis, is solely responsible fordetermining the final selection of products and related accessories.The user shall be responsible for determining if the products arerequired to meet specific design requirements as required by anygovernmental agencies or industry standards applicable to thedesign of the user’s equipment. User must insure that all safetyrequirements are met and safety guidelines are followed andthat the particular use/application of any product and accessoriespresents no health or safety hazards. The user is also responsiblefor providing all appropriate health and safety warnings on theequipment on which the products will be used and/or installed.SEAL SELECTION CRITERIAWhen selecting the seals for a particular application, itis extremely important to read and understand all pertinentinformation on the operating fluids to be used in the systemor contact Tobul engineering for assistance. A wide varietyof fluids can be utilized in systems and can occasionally havedeleterious effects on the accumulator seals if the seal compoundsare not compatible with the fluids. Additionally, dynamic sealsare wear items. The rate of wear depends on many factors andcan rapidly increase if the product and/or the system and/or the system fluid is not properly maintained/filtered.ACCUMULATOR MOUNTING andPORTING CONSIDERATIONSTobul Accumulator, Inc. recommends mounting ofaccumulators in a vertical configuration (with the fluid port on thebottom) for optimum performance. This configuration minimizesthe chance that system/fluid contaminants may be depositedwithin the accumulator, as may occur when accumulators aremounted horizontally. Horizontal orientation and/or contaminationcan result in premature seal wear and/or premature failure.Installers/users must insure accumulators are mountedsecurely, and the hydraulic system plumbing should never bethe sole method of mounting. When “U-Bolt” type clampsare utilized, the installer/user must insure the clamps are notexcessively tightened, especially on piston-type accumulators, toprevent distortion of the pressure vessel wall. Welding mountingbrackets to any type of accumulator is NOT recommended.Accumulator ports must be sufficiently sized to providethe required fluid flow as specified by the user, but mustalso be of a recommended design for the pressure ratingof the system. The preferred port type is one sealed byan elastomeric seal designed for the system pressure,rather than an interference fit such as a pipe thread.ACCUMULATOR PRE-CHARGE—————————WARNING!—————————ACCUMULATORS SHOULD BE CHARGEDONLY WITH AN INERT GAS, SUCH AS DRYNITROGEN. NEVER USE OXYGEN!Only qualified personnel following the manufacturer’sinstructions and utilizing only components specified by theaccumulator manufacturer should perform pre-chargingof an accumulator, or the periodic checking of proper precharge.Accumulators function due to differential pressures.The specific differential within the system is determinedby the system’s operating parameters. Variation from thispressure will cause the system to degrade in performance.REPAIRS AND MODIFICATIONSTobul products are NOT to be disassembled and/ormodified after leaving the manufacturer. If products requiremodifications, these modifications must be performed byTobul Accumulator, Inc. or by a factory authorized facility.Disassembly of any Tobul product for the purpose of preventivemaintenance and/or seal replacement is allowed ONLY afterproper factory authorized training of all involved personnel.ALL ACCUMULATORS ARE PRESSURE VESSELSAND MUST BE HANDLED WITH THE UTMOSTCARE BY QUALIFIED PERSONNEL ONLY!
