Did you know that dry room air: • Causes the membranes in your respiratory system to dry out, and also causes chapped lips and stinging eyes? • Encourages infections and illnesses of respiratory system? • Causes weariness, tiredness and poor concentration? • Stresses household pets and house plants? • Encourages the formation of dust and the electrostatic charging of textiles made of synthetic fibers, carpets and plastic flooring? • Damages furnishings made of wood and parquet? • Detunes musical instruments? Unpacking • Carefully remove the humidifier from the box. Place your hands underneath the product to pull it out of the box (10). • Warning: Do not take the unit out of the box by pulling up on the tank handle - base may fall and will be damaged (11). • Warning: The mist outlet is packed in a red bag inside the box insert. Make sure that you remove the mist outlet from the packaging (12). • Remove the plastic bag from the humidifier. • Observe the information given on the rating plate about the voltage. • Use the original packaging for storing the appliance if you do not use the humidifier all year round. 10 11 General information A comfortable atmosphere indoors is reached with a re lative humidity level between 40 and 60%. Your humidi fier automatically controls the humidity level according to desired setting. If the air is too dry, the humidifier will automatically switch on. As soon as the desired humidity level is reached, it will switch off. 12 Description of the appliance Mist outlet (rotating) Evaporation chamber Water tank Demineralization cartridge Water tank cap Brush Water base Control panel Main body Water level sensor Membrane Ionic Silver Stick® (ISS) (optional) Setting up Finding the ideal location for your unit • Do not place the humidifier directly next to a heating element or on a floor with floor heating. The moisture of the mist can damage the floor surface (6) (see Sa fety Instructions). • The unit should be placed in an elevated position (7), e.g. on a table, chest, etc. • The mist outlet must not be pointed directly at plants or other objects (13). Keep distance of at least 20 inches (50cm). • Soak the demineralization cartridge in a water bath 24 hours before using it (14). The resin has to absorb water to reach high performance. If it is soaked in the tank, make sure to exchange the water and empty the water from the base before using the humidifier. • On average the demineralization cartridge should be replaced every 2 – 3 months depending on your water hardness. Some areas may need to replace the cartridge sooner, some may last longer. The cartridge must be exchanged at the latest after 6 months or the unit does not reach its full performance anymore. See «Replacement of the demineralization cartridge». • Read the instructions under «Filling the Tank» for adding water in the humidifier (15 and 16). • Place the water tank onto the base. • Insert the plug into the socket and switch on the appliance using the on/off switch (19). • About 10 to 15 minutes after having been switched on the device will reach its full power. • Make sure that the cable is not pinched anywhere (9). Do not operate the humidifier if the cable is dama ged (2). en 13 14 Power plug Air inlet en Filling the tank Always unplug the unit before removing the water tank. Do not touch the water in the base during operation! 15 18 16 19 Do not operate the humidifier when the water tank is empty! When the water reaches the minimum level, the unit switches off the nebulizer function automatically. The red light comes on indicating tank is empty. • Make sure that no foreign objects are in the water tank. • Take off the water tank cap to fill the tank with water (15). Fill the tank with clean, cold water from the tap (16). Close the cap of the water tank securely, place the water tank onto the base (17). The water is now running from the tank into the base. • Do not pour water into the mist outlet of the appliance (18). • Insert the plug into the socket and switch on the appliance using the on/off switch (19). The green light comes on. O 7133 Use of additives Water additives (ethereal/essential oils, fragrances, eucalyptus, water conditioners etc.) must not be used! Even a small amount can cause cracks in the material. The material isn’t made for the use of such additives. One drop is enough to damage the tank and as a conse quence the unit. Any use of such additives will void the manufacture’s warranty. 10 7135 17 I Operation of the 7133 model Operation of the 7135 model D B D I O B C A A) On-off dial and regulation of mist output Turning the right-hand rotary dial clockwise switches the appliance on and at the same time regulates the mist out put from low to high. B) Hygrostat (setting the humidity level) The desired humidity level can be set by turning the lefthand rotary dial clockwise. A relative humidity of between 40% and 60% is recommended. You can achieve this level by rotating the dial until it is roughly in the vertical posi tion. The measurement accuracy is +/- 5%. As soon as the humidity exceeds the desired setting, the appliance swit ches off. The appliance does not switch off if the dial is turned all the way to the right as far as the arrow symbol. This activates the continuous operation function. C) Operation with water pre-heating Pressing the pre-heating button (at the bottom between the two rotary switches) pre-heats the water to 176° F (80° C) before it enters the nebulizer space. The mist will now be emitted at a pleasant 104° F (40° C). The advantages of this are that the room temperature does not fall and water cleanliness is significantly improved. D) Empty indicator The water level is easy to see, thanks to the transparent water tank. The appliance also alerts you when the wa ter tank is empty. The red empty indicator is illuminated (symbol D). Please read the chapter „Filling the tank“ for more information. H G F E C A A) On-off switch Switch the air humidifier on or off by pressing button A. E) Setting the timer With button E you can set the humidifier to operate for between 1 and 9 hours, or on continuous operation. When selecting the desired time, «TIME» will be shown on the display. The display will automatically show the current humidity value after a few seconds. F) Mist output (regulating mist output) The mist output can be regulated by pressing button F several times. If the red bars are displayed, you have selected the highest level of mist output. G) Operation with water pre-heating B) Cleaning indicator If symbol B and «CLEAN» appear on the display, the appli ance should be cleaned as recommended by the manufac turer. This symbol comes on automatically every 2 weeks, depending on the level of use. The display can be reset by depressing button A until light disappears. Button G is used to switch the pre-heating function on or off. Switching the function on pre-heats the water to 176° F (80° C) before it enters the nebulizer space. The mist will now be emitted at a pleasant 104° F (40° C). The advan tages of this are that the room temperature does not fall and water cleanliness is significantly improved. C) Hygrostat (setting the humidity level) H) Automatic mode and Sleep mode Set the desired humidity in % by pressing button C. A relative humidity of between 40% and 60% is recommen ded. The humidity can be set between 40% and 75%. The measurement accuracy is +/- 5%. As soon as the humidity exceeds the desired setting, the appliance switches off. The device does not switch off if the display is set to «Co» (conti nuous operation). The desired value will be indicated during selection. After a few seconds, the display automatically shows the current value. D) Empty indicator The automatic and sleep mode «ZZZ» can be activated by pressing button H. If the automatic function is activated («AUTO» appears on the display), the ideal air humidity is maintained relative to the temperature. This is regulated using the output quantity and the preset desired value. If the «ZZZ» function is set, the desired humidity is 60%; the time setting is automatically set to 6 hours; the heating element is switched on. In addition, the output quantity is regulated, depending on the difference between the desired and the actual values. The water level is easy to see, thanks to the transparent water tank. The appliance also alerts you when the water tank is empty. The empty indicator is illuminated (symbol D). Please read the chapter „Filling the tank“ for more information. 11 en en Cleaning/Maintenance Always unplug the unit before removing the water tank. Do not touch the water in the base during operation! 20 24 O I • Switch off the appliance and unplug it from the socket before cleaning it (20). • Clean the water tank and the base regularly. Use water only, no detergents (21). • Use AIR-O-SWISS EZCal custom cleaning and descaling agent to remove deposits from the membrane regularly (22 - 23). There is a sample of EZCal included in the packaging of your humidifier. Instructions for using are on the packet. Only use 1 packet for 32 oz of water. Do not change te ratio. Do NOT run the unit when using EZCal. This can cause damage to the product and voids the warranty. Thoroughly rinse the base with potable water after using EZCal and make sure no EZCal resi dues remain in the base. • Do not submerge base in water (24)! • The cleaning indicator still appears on the display after cleaning. To reset it hold down the ON/OFF button until the clean light stops flashing. 7133 7135 25 21 Caution – risk of electric shock and damage of the product! • Make sure main body is never submerged into water (24)! • Clean the inner parts with a soft cloth. Do not use any solvents or aggressive cleaning agents to clean the appliance (25). • Only use the brush to clean the membrane. This should be done once a week. Only use the soft-bristle portion of the brush. • Change the water in the tank at least once a week if water is standing for more than a week. 12 AC ID 22 23 Replacement of the demineralization cartridge 26 31 32 34 en Always unplug the unit before removing the water tank. Do not touch the water in the base during operation! The water tank is equipped with a demineralization cart ridge. This cartridge has to be replaced every 2 – 3 months. If the water is very hard, it may be necessary to replace the cartridge earlier. White dust around the device is a sure sign that the cartridge needs replacing. Please note white dust is not harmful. If white residue still forms around the device after a new cartridge has been inserted, please make sure that the water you are using is untreated. If the water flows through a decalcification system – such as an ion exchanger - (sodium is added to remove calcium) in the building before it is used in the humidifier, salt can precipitate as white dust around the device. The demineralization cartridge and or the granules must be exchanged at the latest after 6 months or the unit does not reach its full performance anymore. 27 28 33 29 30 35 Option A: replace the resin • Remove the water tank from the base and unscrew the water tank cap (26). Caution: the mist outlet is loose! • The demineralization cartridge is attached to the inside of the tank cap. Unscrew the cartridge from the cap by turning it counter-clockwise (27). Important: do NOT dispose of the water tank cap! • Open the cartridge (28). • Throw the content into the waste (Attention! Disposed resin can make the floor slippery!) (29). • For refilling the DMC, wad a piece of paper towel and place it in the middle of the DMC. For placing granules in the cartridge, a suggestion is to use a spoon so that granules do not get in the middle of the cartridge (31). Placing granules in the middle allows them to escape everywhere or to clog the unit. The unit will no longer operate properly and the granules need to be cleaned out thoroughly. • Close the cartridge (33). 13 en • Screw the cartridge on the water tank cap (34). • Close tank cap well, place the tank on the lower part and insert mist outlet (35). • Soak the demineralization cartridge in a water bath 24 hours before using it. The resin has to absorb water to reach high performance. If it is soaked in the tank, make sure to exchange the water and empty the water from the base before using the humidifier. Option B: replace the whole cartridge • Remove the water tank from the base and unscrew the water tank cap (26). Caution: the mist outlet is loose! • The demineralization cartridge is attached to the inside of the tank cap. Unscrew the cartridge from the cap by turning it counter-clockwise (27). Important: do NOT dispose of the water tank cap! • Throw the whole cartridge into the waste (30). • Unpack the new cartridge (32). Cut the bag open at the marked point. • Close tank cap well, place the tank on the lower part and insert mist outlet (35). • Soak the demineralization cartridge in a water bath 24 hours before using it. The resin has to absorb water to reach high performance. If it is soaked in the tank, make sure to exchange the water and empty the water from the base before using the humidifier. 14 Water quality maintenance 36 Lifecycle Indicator 37 An Ionic Silver Stick® (36) keeps the water free of micro bial growth. This is an optional accessory. However, we as the manufacturer highly recommend to use it in order to keep the unit safe and free of microbial growth. The antimicrobial action of silver is used. The Ionic Silver Stick® (ISS) releases silver ions in the water over a long period (approx. one year). It‘s self-regulating and maintenancefree. Look at picture 36 for the position of the ISS in the base part of the unit. Do not touch the water in the base during operation! Switch off the unit first. Contact your local retailer or check our website www.airoswiss.net for reorder information. Your appliance comes as standard with a lifecycle indicator for changing the Ionic Silver Stick®. To remind yourself of when you put the ISS into operation, please cross the cur rent month on the stamp and write the current year on the line provided (37). Storing the appliance for extended periods Clean the appliance as described earlier and allow to dry thoroughly. Preferably store the appliance in its original box, in a dry place away from high temperatures. Legal notice The humidifier is cUL-listed. Subject to technical change.

Why isn’t there enough moisture in my room? A. How often do you run the unit? If the unit is only run at night, then during the day the moisture level will drop if moisture is not constantly added to the air. Q. Do you leave your door open or closed when the unit is running? a. By leaving the door open, this allows moisture to leave the room and go into other areas of the house. If you would like the moisture to stay within one specific room you should consider closing the door while the unit is running. b. Wood, leather, carpet, curtains, and other types of fabric soak up a lot of moisture, thus not leaving enough moisture for the air. If the window is left open, then this allows moisture to escape the room. Another factor is a lot of times the unit is placed next to a heating device. The idea is that the air blowing into the room will quickly place moisture around the room. Unfortunately, this concept does not work because the hot air coming out of a vent will soak up most of the moisture, and none of the air within the room will receive any. Q.How much moisture do I need in my room? A. Suggested humidity levels are between 40 – 60%. Q.What are the effects of too little or too much humidity? A. Dry air can cause dry skin, static electricity, out of tune musical instruments, increased levels of dust (dry air causes dust to rise), damage to wooden objects (dry out and eventually cracks appear), discomfort, sick ness, and dries out nasal membranes. Over-humidifying the air can cause mold and wallpaper to peel. Q. Why do I need a humidifier when I can just open my window? 16 A. The moisture level within the outside air is not high enough to humidify a room. The colder the air the less moisture it is capable to hold, and the more the air is heated up the percentage of relative humidity is lower. Relative humidity means the amount of water vapor in the air, compared to the amount the air could hold if it was totally saturated. The difference is higher between outside and inside temperatures; more humidification is needed because of the dry air in the room. Q.Where should I place my humidifier? A. The unit should be free-standing and not close to a wall, window, door, or thermal bridge so that air may circulate around the unit. Ultrasonic Frequent Questions Q.Why does it say open/close on the demineralization cartridge cap? A. Those directions are there in case you decide to use the refill option to replace the granules; the purpose is for how to open and close the cap. If you did open the cap before placing it in the water tank, you will most likely notice that there are granules in the water tank and the base of the unit. Immedia tely turn off the unit, and empty the water out of the base and the water tank. Begin removing all granules from base and water tank. Use brush to clean around membrane. Caution: Do not dispose of granules in sink! Used granules must go in waste! Q.I just replaced my cartridge, and the contents and water in the base has turned a blue-green color. A. This sometimes occurs when the cartridge, or even the granules, are replaced. This does not occur with all replacement cartridges or granules, and is a reaction of water content and the Ultrasonic vibrations. This is not an indicator to replace the cartridge. Q.There is no fill-line on the water tank, how far may I fill it up? A. There is no fill line on the water tank, and it may be filled all the way to the top. Q.What is the purpose of the demineralization cartridge (DMC)? A. The DMC removes minerals from the water to prevent white dust as much as possible. The contents of the cartridge need to be soaked for 24 hrs prior to first using the unit so that they may fully expand and remove minerals from the water. The contents of the DMC have a life of 2 – 3 months. The cartridge may need to be replaced more often depending on water hardness and how often the unit is used. An indication of when the DMC needs to be changed can be white dust or reduced amount of mist output. Q.Is it ok to use distilled water with the unit? A. For best results with your ultrasonic humidifier use distilled or reverse-osmosis water and remove the demineralization cartridge. Q.I just replaced the contents of the cartridge and now have granules everywhere. A. First, make sure there are no granules in the middle of the cartridge. Placing granules in the middle of the DMC allows them to escape everywhere. Immedia tely turn off the unit, and empty the water out of the base and the water tank. Begin removing all granules from base and water tank. Use brush to clean around membrane. For refilling the DMC, wad a piece of paper or paper towel and place in the middle of the DMC. For placing granules in the cartridge, a suggestion is to use a spoon so that no granules get in the middle of the cartridge. Caution: Do not dispose of granules in sink! Used granules must go in waste! Q. The directions tell me not to place the unit directly on the floor, why do I have to elevate the unit? A. The idea with this unit is to allow one to force more humidity into the air than is needed. Because of this, the carpeting or wood floor surrounding the unit may become damp. If the unit is placed at least 3 feet off the floor, the mist will have the opportunity to evapo rate before hitting the floor. Q. Water does not go into the tank. A. In order to fill the tank, it must be turned upside down. The cartridge is placed on the water tank cap. Do not pour water in the tube which is the mist outlet. Q. White dust is emitted from the unit A. White dust particles are minerals that are broken up in tiny pieces by the ultrasonic process. Solve the problem: • Soak the demineralization cartridge in a bowl of water for a minimum of 24 hours. If the cartridge is soaked in the water tank, the water in the tank and the base needs to be replaced before using the unit. • Exchange the demineralization cartridge after 1-2 months when you use very hard water (for softer water after 2-3 months). No matter how hard your water is, exchange the cartridge at the very latest after 6 months. • Don’t use water from a pre-installed water softener, or sodium instead of calcium will be emitted from the unit. Use distilled water instead and remove the demi neralization cartridge. • For very hard water areas use only distilled water and remove the demineralization cartridge. • Use Reverse-Osmosis water (R-O water) instead of dis tilled water and remove the demineralization cartridge. • Cleaning light is flashing (model 7135, 7142) Switch off the unit and unplug it. Empty the water in the base. Rinse the base with hot/clean water. Do not submerge the base! Visually inspect the base for dirt or mineral build up. If soft water is used decalcifying the unit every 4 weeks with EZ Cal is suggested. If hard water is used the unit should be decalcified every 2 weeks. Do not forget to reset the clean light after reset ting the unit. the lower is the percentage of relative humidity (=the amount of water vapor in the air, compared to the amount the air could hold if it was totally saturated) • position of the unit - if it is placed close to a door, win dow or air vent. This increases the air circulation. Q. Reset cleaning light (model 7135/7142) A. The cleaning light does not automatically reset. Hold down the power button (button A in instruction manual) until the light stops flashing. The light automatically comes on approx. after 14 days of plugging in the unit. Q.Tank is leaking A. Check if there are any hairline cracks. Dropped units or water tanks that are cracked will not be covered under the warranty. Please contact the retailer the unit was purchased from in case your unit arrives damaged. Q.The hygrometer on unit reads a different humidity level than external hygrometer. A. Not all hygrometers are calibrated the same, and most are off by +/- 5%. Plus the humidity level is not the same in the whole room. The air circulation is different in every corner of the room. The unit should not be placed near a heat vent or a radiator as the heat will absorb all of the moisture. Q.Placing the face in the mist A. It is not recommended that anybody places their face in the mist. It is an electrical product and should not be played with. Q. Humidity level is not changing or does not reach the desired humidity level. A. If the water tank needs refilling more than once per day, the unit is working properly and the climatic condi tion in the room has an influence on the humidity. Reasons for low humidity level: • air circulation is very high (air is fully exchanged se veral times per day – the humidifier needs to starts its work from scratch) • insulation of home (see air circulation) • open space with high ceilings (not only the footage of the room counts but also the height) – high-rise buil dings require more humidification. • open windows – works similar to air circulation (if it is very cold outside don’t open the window more than 2 times per day for 3 minutes • big difference between outside temperature and inside temperature – the colder the air the less moisture it is capable to hold and the more the air is heated up Q.No mist / unit is not working / empty indicator keeps flashing A. Fill up the water tank. Check if water is flowing through the demineralization cartridge (attached to the water tank cap). If the water tank is full but there is only little water in the base it indicates that the water is now flowing through the demineralization cartridge. • Wait for 15 minutes to allow the mist to come out of the unit. • If the unit is not working and the empty light is not flashing you might have set the desired humidity too low and the current humidity level in the room is hig her. That is why the unit switches off automatically. • If the empty indicator keeps flashing and the tank is full, the water is not flowing through the cartridge. Exchange the cartridge or the granules in the cartridge after 2-3 months, in areas with hard water exchange the cartridge after 1 -2 months. However, the demi neralization cartridge and or the granules must be exchanged at the latest after 6 months or the unit does not reach its full performance anymore. • If the granules are new, see the following instructions: • Make sure the cartridge and/or granules were soaked 17 en en for 24 hours, dry granules take even longer for water to filter through the cartridge and into the base. Next, please remove a tablespoon of granules from the cart ridge, and throw them away. When there are too many granules in the cartridge it does not allow water to flow from the tank to the base. Q:Water tank cap is too tight to unscrew A: This could be a cause of the air pressure within the water tank. Depress the spring on the bottom of the water tank cap to release air from the water tank. Continue to do this until you are able to unscrew the water tank cap. Q:Unit is running intermittently. A: How long has it been since the contents of the cart ridge were replaced? If 2-3 months have passed, it is time to replace the contents of the cartridge. However the demineralization cartridge and or the granules must be exchanged at the latest after 6 months or the unit does not reach its full performance anymore. • If the contents of the cartridge were just replaced there are probably too many granules in the cartridge. Re move a tablespoon of granules from the cartridge. 18 Accessories Q:Do I need to keep any parts before I replace the demineralization cartridge? A: Yes, always keep the water tank cap (this is the piece that attaches the demineralization cartridge to the water tank). Q:Ionic Silver Stick® (water treatment) replacement reminder A: In each Ionic Silver Stick® (ISS) box and on all the new products there is an ISS lifecycle indicator. Check the box of the month when starting to use the ISS and write the year on the line indicated. Exchange it after 12 months. Q. What is EZ Cal? A. EZ Cal is used for cleaning and descaling any of the AIR-O-SWISS products, and cleans mineral build-up. Instructions for using are on the packet. Only use 1 pa cket for 32oz of water. Do not change the ratio. Do NOT run the unit when using EZCal. This can cause damage to the product and voids the warranty. Thorougly rinse the base with potable water and make sure no EZCal residues remain in the base! It can also be used for any other humidifier brand. for 24 hours, dry granules take even longer for water to filter through the cartridge and Please check our website www.airoswiss.net for further information.
