Manual-no.: 999122 / 02/09/2009page 4 of 21Remove all packing material, remove the product from its packing-box, remove theprotective covers from the inlet and outlet ports and keep, inspect the equipment.If the equipment is damaged, notify the supplier and the carrier in writing within threedays; state the item number of the product together with the order number and thesupplier’s invoice number. Retain all packing material for inspection.Do not use the equipment if it is damaged.If the equipment is not used immediately, replace the protective covers. Store theequipment in suitable conditions.☞ Read and obey this manual before installing or operating the equipment.☞ Transport the pump at the provided handle.Use the equipment for the intended use only, that is to generate vacuum or to com-press gases in vessels designed for that purpose.☞ Prevent any part of the human body from coming in contact with the vacuum or theoverpressure.☞ Obey notes on correct vacuum and electrical connections, see section ”Use andoperation”.☞ Make sure that the individual components are only connected, combined and op-erated according to their design and as indicated in the instructions for use.Obey national safety regulations and safety requirements concerning the use ofvacuum and electrical equipment.☞ Equipment must be connected only to a suitable fused and protected electricalsupply and a suitable earth point. Failure to connect the motor to ground mayresult in deadly electrical shock.☞ The supply cable may be fitted with a moulded European IEC plug or a plug suit-able for your local electrical supply. If the plug has been removed or has to beremoved, the cable will contain wires colour coded as follows: green or green andyellow: earth; blue or white: neutral; brown or black: live.☞ Check that mains voltage and current conform with the equipment (see rating plate).☞ If the equipment is brought from cold environment into a room for operation, allowthe equipment to warm up (pay attention to water condensation on cold surfaces).☞ Make sure ventilation is adequate if pump is installed in a housing or if ambienttemperature is elevated.Obey all relevant safety requirements (regulations and guidelines) and adopt suit-able safety measures.☞ Provide a firm level platform for the equipment and check that the system to beevacuated is mechanically stable and that all fittings are secure.Attention: Flexible elements tend to shrink when evacuated.☞ When operating the pump as a pressure pump, ensure that the maximally gen-erated overpressure is compatible with the mechanical stability of the pressurevessel. Overpressure may be generated only in vessels which are designed forthat purpose. Risk of bursting!Attention: Obey the maximally admissible pressure (4 bar absolute) at the outlet.If necessary install an overpressure safety relief device. Flexible elements tend toexpand when pressurised.☞ Obey maximum permitted pressures and pressure differences, see section ”Tech-nical data”. Do not start the pump with overpressure at the inlet.Do not permit any uncontrolled pressurizing (e. g. make sure that the exhaust pipe-line cannot become blocked). Risk of bursting!Safety information!
