• Do not insert or remove the electric plug on the humidier with wet hands.5

• If the mains cable is damaged it must be replaced by the manufacturer, its service agent, or similarly qualied person in order to avoid a hazard.

• To reduce the risk of electric shock, do not remove screws. The humidier does not contain any user- serviceable parts. Please leave all maintenance work to qualied personnel.

• Fill the water tank with fresh, distilled or demineralized water. Do not drop any other liquid into water tank or main base. Do not run the humidier when there is no water in the water tank.

• Do not shake the humidier as this might cause the water spill over into the base of humidier.

• Never touch the water or components while the humidier is in operation.

• If there is an unusual smell when it is being used as described in this manual, switch the humidier off, unplug it and have it examined by your dealer.

• Do not pour hot water into the water tank, i.e. at a temperature in excess of 40°C.

• Do not immerse the humidier or the mains cable or plug in water or other liquids.6

• Never scrape the transducer with a hard tool. The humidier must be cleaned regularly. To do this, refer to the cleaning instructions in this manual.

• If you spill any liquid into the humidier, it can cause serious damage. Switch it off at the mains immediately. Withdraw the mains plug and consult your dealer.

• Disconnect the humidier from the power supply when not in use and before cleaning.

• Do not use the humidier if the air in the room is already sufciently humid.7

• The ideal relative humidity level for human comfort is in fact between 45% and 65%. Excess humidity shows up in the form of condensation on cold surfaces or cold walls in the room. To measure the room’s humidity correctly, use a hygrometer available in most specialist shops and hypermarkets.

• This product is intended for indoor, non-industrial, non-commercial, household use only.

• Unplug the appliance during lling and cleaning.

TROUBLESHOOTING Problem Possible reasons Solutions Power lamp is off when switched on. Humidier is not plugged in. Plug the humidier into a powered electrical socket. Power cord is damaged. Immediately stop using it and contact Customer Support. Humidier is defective or malfunctioning. Press the power button to turn it on. Power lamp is on when switched on, but no mist comes out. Humidier is not turned on. Press the power button to turn it on. The target humidity is reached. Increase the target humidity or change mode. Water shortage indicator is on. No water in the tank. Rell the water tank wait at least 1 minute. Water level is low. The water level required has not yet reached the vaporization compartment. Wait at least 1 minute. The water tank isn’t well positioned. Check the positioning of tank on the base. The humidier isn’t on a at surface Check the positioning of the humidier. Humidier produces an unusual smell Humidier is new. Take out water tank, open cover, let it stay 12 hours in cool position. Dirty water or water sitting too long. Clean water tank, ll with clear water. Residual smell from diffusing aroma oil on the aroma cotton. Remove the aroma cotton, rinse it under clean water and allow it to dry.13

Humidier makes a loud or unusual sound. Resonant in water tank when water is too low. Fill water into water tank. Humidier is on an unstable surface. Move the humidier to a stable at surface. Water tank is positioned incorrectly. Turn off and unplug the humidier, then align the water tank cover with its respective opening in the inner chamber. Humidier is malfunctioning. Immediately discontinue use and contact Customer Support. The humidication capacity is too low. There is natural or articial air replacement in the room which interfere the increase of %RH. Check if doors and windows are closed. Check if there is no air conditioning working in the room. The air inlet grids, and nozzle could be blocked. Remove any blocking items from the grids and the nozzle. Too much scale in the main base or water tank. Clean transducer. The humidity selected rate is too low. Increase mist output speed. Increase humidity setting rate. Water is too dirty, or water is kept too long in the tank. Clean water tank, change to fresh clear water. There is condensation in the room. The room temperature is too low. Heat the room up. The mist suddenly stops coming out. The water shortage indicator is on. Rell water tank. Control button does not work Hands are too wet when operating control panel. Keep hands dry while operating the control panel. Humidier has malfunctioned. Contact Customer Support.14

White dust appears around the humidier. Water being used has a high mineral content. Use distilled water with the humidier. If distilled water is not available, use puried or ltered water. Humidier was not properly cleaned after last use. Clean humidier. Mist is coming out from the base. Water tank is not positioned correctly. Turn off and unplug the humidier, then align the water tank cover with its respective opening in the inner chamber. Mist fog coming out from around nozzle. There are apertures between the nozzle and water tank. Reposition the cover and check if the nozzle is well plugged in the cover. The following is not considered faulty operation:

• If your water is very hard (containing abnormally high levels of minerals) the humidier may produce white dust. This is not a malfunction. The solution would be to clean the lter more often or use softer water.

• If you stand very close to the humidier, you will hear the gurgling sound of water. This is normal.

• The humidier operates very quietly but it is not completely silent. Noise levels less than 35dB(A) is considered normal. MAINTENANCE If the water is hard, meaning that the water contains too much calcium and magnesium, it can cause a “white powder” problem and leave heavy scales on the inner surface of the main base, transducer and inner surface of the water tank. Scales on the surface of transducer will let the humidier work improperly. Use cold boiled water or distilled water. Empty the tank and rell every third day. Before relling, clean it with fresh tap water or cleaning agents if required by the manufacture. Remove any scale, deposits, or lm that has formed on the sides of the tank or on interior surfaces and wipe all surfaces dry. Empty and clean the humidier before storage. Clean the humidier before next use.15

HOW TO CLEAN THE TRANSDUCER

• Clean with clean water of citric acid if there is scale in it.

• Brush off the scale from the surface.

• Rinse the transducer with clean water.

HOW TO CLEAN THE BASE

• Clean the inner surface of the main base with a soft cloth or use citric acid if there is scale in it.

• If the scale covers the security switch, drop some citric acid on it and let it sit for 2-5 minutes on the scale and clean it with a brush.

• Rinse the water tank with clean water.

HOW TO CLEAN THE CERAMIC FILTER

• Clean and activate the ceramic ball after using 1000L water. Depending on the water quality. If the ceramic ball is dirty it needs to be cleaned more frequently.

• It can be dipped into vinegar for 5 minutes, then rinse it with water.

• Put the lter under the sun for 4-6 hours to dry, over over night.16
