Manual-no.: 999188 / 19/05/2009• The pumps are not suitable for pumping substances which may form depositsinside the pump. Deposits and condensate in the pump may lead to increasedtemperatures even to the point of excessing the maximum permitted tempera-tures!• If there is a danger of formation of deposits in the pump chamber (check inlet andoutlet of the pump), inspect the pump chambers regularly and clean if necessary.• The pumps are not suitable for pumping dust and have no approval for opera-tion below ground.If pumping different substances, it is recommended to purge the pump with air orinert gas prior to changing the pumped media in order to pump out residues and toavoid reactions of the pumped substances with each other and with the pump ma-terials.Take into consideration interactions and chemical reactions of the pumped me-dia. Ensure that the materials of the wetted parts are compatible with the pumpedsubstances, see section ”Technical data”.Safety during operation➨ Adopt suitable measures to prevent the release of dangerous, toxic, explosive,corrosive, noxious or polluting fluids, vapours and gases. In case install an ap-propriate collecting and disposal system and take protective action for pump andenvironment.➨ The user must take suitable precautions to prevent any formation of explosivemixtures in the expansion chamber or at the outlet. In case of e.g. a diaphragmcrack, mechanically generated sparks, hot surfaces or static electricity may ignitethese mixtures. Use inert gas for gas ballast or venting if necessary.➨ Potentially explosive mixtures at the outlet of the pump have to be drained ap-propriately, sucked off or diluted with inert gas to non-explosive mixtures.☞ Pay attention to the symbol ”hot surfaces” on the equipment. Adopt suitablemeasures to prevent any danger arising from the formation of hot surfaces orelectric sparks. Provide a suitable protection against contact if necessary.☞ Pumping at high inlet pressure may lead to overpressure at the gas ballastvalve. Pumped gases or condensate might be pushed out in case the valve isopen. If an inert gas supply is connected, ensure that the inlet pipeline is not con-taminated.• Comply with applicable regulations when disposing of chemicals. Take into con-sideration that chemicals may be polluted.Take adequate precautions to protect people from the effects of dangerous sub-stances (chemicals, thermal decomposition products of fluoroelastomers), wearappropriate safety-clothing and safety glasses.• Use only genuine spare parts and accessories. Otherwise safety and perform-ance of the equipment as well as the electromagnetic compatibility of the equip-ment might be reduced.Possibly the CE mark or the C/US conformity becomes void if not using genuinespare parts.• Attention: If the pressure is higher than approximately 1080 mbar the pressurereading becomes incorrect (saturation of the pressure transducer). The displayflashes. Immediate pressure relief necessary! Risk of bursting!• Provide appropriate protective measures (i.e precautions which allow for the re-quirements of the respective application) even for the case of failure and mal-function.NOTICE
