127 / 13709/2008 5 C72IGBFDESetting to work - connection to the power-supplyATTENTION DANGER !Make sure that the vacuum cleaner is in perfect-condition before commencing work.Before plugging the vacuum cleaner into the elec--tricity mains, make sure that the voltage ratingindicated on the data plate corresponds to that ofthe electricity mains.Plug the vacuum into a socket with a correctly in--stalled ground contact/connection.Make sure that the vacuum cleaner is off.-The plugs and connectors of the connection cables-must be protected against splashed water.Make sure that connections to the electricity main-and plug are correct.Only use vacuum cleaners when the cables that con--nect to the electricity main are in perfect condition(damaged cables could lead to electric shocks!).Regularly check that the electric cable does not show-signs of damage excessive wear, cracks or ageing.ATTENTION DANGER !When the vacuum cleaner is operating, do not:crush, pull, damage or tread on the flex that connects-to the electricity main;only disconnect the flex from the electricity main by-removing the plug (do not pull the flex);only replace the electric power cable with one of the-same type as the original: HO7 RN-F. The same ruleapplies if an extension is used;the flex must be replaced by the manufacturer’s As--sistance Service staff or by an equivalent qualifiedpersonnel.Extensions-If an extension is used, make sure it is fit for the power drawand protection degree of the vacuum cleaner.Minimum section of extension cables L = 20 m max - Cable= HO7 RN - F.Maximum power (kW) 3 5 15 22Minimum section (mm2) 2.5 4 10 16ATTENTION DANGER !Sockets, plugs, connectors and installation of the exten-sion cable must maintain the IP protection degree of thevacuum cleaner, as indicated on the data plate.ATTENTION DANGER !The vacuum cleaner’s power socket must be protectedby a differential circuit-breaker with surge current limita-tion, that shuts off the power supply when the currentdispersed towards ground exceeds 30 mA for 30 msec.or an equivalent protection circuit.ATTENTION DANGER !Never spray water on the vacuum cleaner: such actionconstitutes a danger hazard for persons and couldshort-circuit the power supply.Consult the latest edition of the European Union Direc-tives, the Laws in the country of use and the currentstandards in force (UNI - CEI - EN), particularly Europeanstandard EN 60335-2-69.Wet and dry applications-NoteThe supplied filters and the safety container (if applicable)must be installed correctly.If the machine is used to clean up liquids, make sure thatthe liquid level sensor activates and operates in the correctway.ATTENTION DANGER !Comply with the safety regulations governing the ma-terials for which the vacuum cleaner is used.ATTENTION DANGER !If the wet cleaner variant is used:make sure that the liquid level sensor operates cor--rectly before using the vacuum cleaner to clean upliquids;if foam forms, immediately stop work and empty-the container.Warning: switch off the vacuum cleaner immediately-if foam or liquid leaks out.Regularly clean the liquid level limiting device and-check to make sure that there are no signs of dam-age.Warning: the dirty liquid collected by the vacuum-must be considered conductive.
