VAPORETTO EDITION - VAPORETTO EVOLUTIONPREPARATION FOR USE1. Unscrew the patented safety cap (A) and fill theboiler with about 1,3 litres of water using the fillerbottle / funnel (14) making sure that it doesnot overflow (fig. 1). Normal tapwater can beused. However, as hard water by its naturecontains limestone, which may cause a buildupof limescale in the tank, in hard water areaswe recommend the use of our natural-base decalcifierKALSTOP, available from your Poltidealer or by mail order from your Polti serviceCentre.2. Carefully screw on the safety cap to hand tight(Fig. 2). Make sure the patented safety cap (A)is fully and correctly screwed on, otherwise youmay experience steam escaping from aroundthe cap.3. Connect the power supply cable (F) into anearthed power supply of the correct voltage.WARNING: Do NOT under any circumstances putor leave the filler bottle in the water filling apertureof the appliance when the appliance is connectedto the mains electricity supply. Danger of burns!Always make sure generator on/off switch (B) isswitched OFF before connecting the appliance tothe mains.INSTRUCTIONS FOR USE1a. Press down the generator on/off switch (B) andthe accessories on/off switch (C) which will lightup.2a. Open the cover of the central connector block(D) and insert the central connector (4) pressingthe connector button (5) and taking carethat the locking tab (6) is correctly positioned inthe lock-in aperture (E) on the block (Fig. 3).3a. When the generator on/off switch (B) goes out,the steam cleaner is ready for use4a. The steam gun (2) is equipped with a safetyswitch (2A) which prevents the accidental startof the steam jet by children or people who donot know how to operate the appliance.With the switch (2A) in the “OFF” position, thelever controlling the steam jet is locked(Fig.4b). Should the hose be left unattended fora moment whilst the appliance is connected tothe mains, it is recommended to put the safetyswitch in the “OFF” position. To start working,set the (2A) switch to the “ON” position andpress the steam button (Fig.4a).The first burst of steam may contain some waterdroplets, due to imperfect thermic stabilisation insidethe flexible hose. We would therefore advisethat the first jet of steam is played onto an old clothuntil a constant pressure of steam is obtained.Note: The generator on/off switch (B) may go onand off from time to time during use of VAPO-RETTO. This means the machine is maintaining thecorrect and constant pressure and is quite normal.STEAM REGULATION FEATUREVAPORETTOs are equipped with a steam regulationcontrol (I) (Fig. 5). You can increase the steamflow by turning the control in clockwise direction.Turning it in an anti- clockwise direction reducesthe steam flow. Here are some suggestions for thechoice of steam flow level:• Strong steam: for encrusted dirt, stains, greaseand for sanitising.• Normal steam: for carpets, rugs, glass, tiles etc.• Delicate steam: for vaporising plants and cleaningdelicate surfaces.Please read separate warning about use on draylon,velvet and other delicate fabrics, or on sensitivewood surfaces.CONNECTION OF ACCESSORIESAll the accessories of VAPORETTO can be connectedto the handle or to the extension tubes asper the following instructions (fig. 6):1b. Move the locking button (11) on the accessoryto the “open” position.2b. Attach the required accessory to the hand gunor to the extension tube.3b. Move the locking button (11) back to the position‘closed’.4b. Check that the locking button has engaged andthe accessory is fully connected.PATENTED SAFETY CAP /’’WATER OUT’’The appliance is equipped with a safety cap, whichprevents opening of the generator tank as long asthere is any pressure remaining inside. This is animportant and indispensable safety device, and it isnecessary to follow the procedure here below whenre-filling the generator tank.When you have used up all the water in the tank,proceed as follows:1c. Switch off the machine at the generator on/offswitch (B)2c. Press the steam request lever (3) on the steamgun (2) or, if using the iron, the steam requestbutton (R) on the iron (Q) so as to fully exhaustthe steam supply from the tank.3c.

Connect the connector assembly at the end ofthe iron hose (4) to the generator as shown inpoint 2a of the section “Instructions for Use”.Check the manufacturer’s label on the garment,and interpret the symbol on the label as follows:Steam ironing allowedFor dry ironing, set thermostat on •••Steam ironing allowedFor dry ironing, set thermostat on ••Check the fabric's resistance to steamironing or dry iron with thermostat seton •- do not iron- steam ironing or treatment not allowedSTEAM IRONING2d. For STEAM ironing, turn the dial (S) and set theiron temperature to its maximum travel on the“COTTON-LINEN” steam position.NB YOU MUST SET AT ITS MAXIMUM PO-SITION, DO NOT SET AGAINST THE PIC-TURE OF THE IRON ON THE DIAL (S).Most types of fabric, other than delicates canbe STEAM ironed at this temperature, pleaseconsult the garment manufacturer’s instructionson the label.NB FABRIC INDICATIONS ON DIAL AREFOR DRY IRONING, NOT STEAM IRONING.3d. Wait for a few minutes until the “Iron heating”indicator light (V) goes out, to show that the soleplateof the iron has reached the requiredtemperature.4d. Press the steam request button (R) to enablethe steam to come out. The steam flow will stopwhen the button is released. After each filling,when you first start to use the iron, a few dropsof water mixed with the steam may be emitted(due to imperfect heat stabilisation). It is thereforeadvisable to direct the first jet of steamonto a rag.5d. The iron can also be used in a vertical positione.g. for removing creases from curtain, clothingetc.6d. To obtain a continuous jet of steam move thesliding button (U). The steam will continue tocome out even when the steam request button(R) is released. To stop the steam flow movethe sliding button backwards (U).NOTE: using the iron, it is advisable to adjustthe steam jet at medium output, or to do sometesting in order to find the position on (U) whichis most suitable to the fabric to be ironed.RECOMMENDED TECHNIQUE for steam ironingwith the Polti iron is APPLY steam (buttonR) on the upstroke, then release button R (sono steam) for the backstroke, thus reclosing thefibres, preventing oversteaming and wetness.DRY IRONING7d. If you need to DRY iron (ONLY) (NOT steamironing), press the accessory on/off switch (C)and adjust the temperature of the iron by turningdial (S) to the temperature required for thefabric (as shown on the dial).ATTENTION: when dry ironing, be careful notto press the steam request button (R), as hotwater could come out of the iron onto your garmentand board.IMPORTANT• Do not leave the iron unattended whilst connectedto the mains.• Iron only on heat resistant surfaces and on surfacesthat allow the steam to escape e.g. MESHironing boards.• ATTENTION: if you iron sitting down, do notplace your legs under the ironing board, thesteam can cause burns.38

VAPORETTO EDITION - VAPORETTO EVOLUTIONTIPS FOR BETTER UNIT PERFORMANCEWARNINGS• For cleaning leather, wood or delicate fabricsespecially dralon, velvet and other pile surfaces,consult the manufacturers instructions. Cleanonly by using the hand gun at a safe distance togetherwith a soft cloth and always do a test on anon visible part of the item first or on a sample.Allow the test area to dry completely before observingresults and effects on surface or colourbefore proceeding to clean further areas.• For cleaning wood surfaces (furniture, doorsetc.) take great care as a too long application ofthe steam could alter the waxed appearance, theshine or the colour of the surfaces cleaned. Wetherefore recommend you to apply the steam onsuch surfaces only for brief periods or to cleanthese surfaces using a cloth first held in thesteam.• Please pay particular attention while cleaningbrick floors: a too long application of steam coulddamage wax, brightness or colour of these surfaces.• For delicate surfaces (e.g. synthetic materials,lacquered surfaces etc.) we recommend toalways cover the small brush with at least twocloths to reduce the intensity of the steam, and(on machines with steam variation control) withthe steam set at low level. Always test first on anon-visible area, allow to dry thoroughly, and ifsuccessful, be sure to use exactly the same tool,technique, steam level and steam jet distance.• If cleaning glass surfaces in particularly low temperaturespreheat the glass using the hand gunfrom about 50 centimetres distance from the surfaceto be cleaned.• For care of your plants vaporise at a minimum distanceof 50 centimetres.STEAM GUN (2)The steam gun can be used directly on all spots requiringa stronger, closer treatment without connectingthe brushes. The more resistant the stain,the closer you should hold the gun, the steam pressureand temperature being higher at the source.Always wipe with a dry cloth (or a slightly abrasivesponge if the spot is a difficult one to remove) afterusing the gun. Steam gun is particularly efficient at:• breaking down rug and carpet stains before theyare treated with the large brush;• cleaning stainless steel surfaces, panes, mirrors,enamelled surfaces;• cleaning hard-to-reach corners, such as stairs,window sills, door posts;• cleaning cooking top knobs, taps bases• cleaning window shutters, heaters, car interiors;• spraying plants (from a distance);• removing odours and creases from clothes.To reach higher points, the steam gun can be connectedto one or both extension tubes.LARGE BRUSH (8)To clean floors, put a clean, dry kitchen cloth underthe brush and swing back and forth without applyingany pressure. Use the other side of the clothwhen the first one is impregnated with dirt. Use thebrush directly without the cloth on particularly dirtyor incrusted areas and in spaces between the tiles:swing the brush sideways to detach the dirt. Highlyobstinate stains may require a steam gun treatmentbefore the brush and cloth are used (an old bathtowel is an ideal cloth) . The same procedures applyto ceilings and vertical surfaces, like wallpaper.The cloth can easily be fastened around the brushand held in place by the 4 clips (9) on the brush itself.Smooth cotton cloths are suitable for the treatmentof glass surfaces: fasten the cloth around thebrush then pass it over the window pane (or mirror)to remove the greasy film. Finally, spray the surfacewith the steam gun and wipe dry with a clean cloth.In cold weather, window panes will require pre-heatingwith the steam gun (from a distance of 50 cm),prior to the actual cleaning with the the brush. VA-PORETTO is ideal for both syntetic and wool rugsas well as for all types of carpets. Its use ensurestotal hygiene, revives colours and restores the originalbrilliance of the pile. Drying occurs practicallyat once. Fold a cotton cloth over 2 or 3 times (accordingto the length and resistance of the pile) andfasten it onto the brush. Move the brush rapidly inall directions without applying any pressure. Youshould avoid lingering in the same place, as thismay soak the area. Particularly dirty rugs may needseveral treatments. Obstinate stains may requirethe use of the steam gun (at a distance of 5-10 cm)prior to treatment.SMALL BRUSH (12)The small brush is used whenever the big brush istoo big or not practical to be used.The small brush can be connected directly to thesteam gun or to the extension tubes. The smallbrush can be used on:• furnishing fabrics (after testing on a small hiddenarea)• car linings (not pile surfaces), car windows (notin freezing temperatures)• small window surfaces• tile and other small surfacesTo clean wood ( doorposts , floors etc) do not applyENGLISH39

ENGLISHVAPORETTO EDITION - VAPORETTO EVOLUTIONthe steam directly but cover the brush (big or small)with a doubled cotton cloth. For furniture cleaning,direct the steam jet onto a dry cotton cloth, andthen start the cleaning. The warm moisture on thecloth traps the dust, spots and the static electricityso that the furniture stays clean longer.120° STEAM NOZZLE (16) (*)The 120° nozzle (which can be connected directlyto the gun or together with the extension tubes) allowsyou to concentrate a powerful jet of steam tootherwise inaccessible locations, such as radiators,door posts, sills and shutters, as well as for sterilisingtoilet bowls. It’s a very useful and indispensabletool.WINDOW SQUEEGEE TOOL (18,19,20) (*)DO NOT USE STEAM ON GLASS IN FREEZINGTEMPERATURESThe window squeegee tool allows you to clean effectivelyand rapidly all glass surfaces without usingdetergents. Your glass will remain cleaner longerthanks to the absence of the film normally leftbehind by chemical cleaning products on whichnew dust and grease can attach themselves.Cleaning glass is done in two stages:• Spray the steam onto the surface to be cleanedto loosen the dirt (not touching with the blade).• Pull the blade straight down the window surfacefrom top to bottom without applying the steam, totake away the dirt.• FOR EXTRA ABRASIVE ACTION AND MOREEFFECTIVE REMOVAL OF DIRT, WE RECOM-MEND USING THE BRISTLES SUPPLIEDWITH THE LARGE WINDOW CLEANING KITTo clean especially large glass surfaces, attach thewindow squeegee tool to the extension tubes.(*) OPTIONAL for Vaporetto EDITIONCARE OF YOUR VAPORETTO• Before attempting any maintenance operation,make sure to always disconnect the appliancefrom the mains• Check periodically the condition of thecoloured washer connections on the centralconnector (4). If necessary, replace thewashers with the spare washers supplied(15).Make the same check also on the connectionwashers of the extension tubes (7) and of thesteam gun (2).• To clean the body of the appliance, simply use amoist cloth.OPTIONAL ACCESSORIESVaporetto can be quickly transformed into a highlyeffective ironing system to make ironingquick and easy.
