Product Usage Instructions

1. Before Use:
   • Clean the humidifier before each use.
   •  Place the humidifier on a flat surface at least 70 cm above the floor level to ensure optimal vapor distribution.
2. Water Filter:
   • Press out the aroma box from the base.
   • Use water-soluble aroma oil and drop it onto the sponge in the aroma box.
   • Put the aroma box back into the humidifier to enable the aroma function while it’s running.
   • To stop the aroma function or when storing the humidifier, clean the sponge in the aroma box.
   • Only drop the aroma oil into the aroma cotton. Do not drop any liquid except clean water into the water tank or basin.
3. Use:
   • Press any button to wake up the light and display.
   • To enter manual mode, slide from MIN to MAX to select your preferred mist output speed. Sliding from left to right increases the speed, while sliding from MAX to MIN decreases it. The display shows the selected speed from 1-5.
4. Troubleshooting:
   • If the power lamp is off when switched on, plug the humidifier into a powered electrical socket.
   • If the power lamp is on but no mist comes out, check for the water shortage indicated and refill the water tank.
   • If the humidifier produces an unusual smell, it may be due to dirty water or a residual smell from diffusing aroma oil. Clean the water tank and aroma cotton accordingly.

READ ALL INSTRUCTIONS BEFORE USE

IMPORTANT SAFETY INSTRUCTIONS

• Please follow all the safety precautions listed below for safety and to reduce the risk of injury or electrical shock.
• This humidifier can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the humidifier in a safe way and understand the hazards involved. Children shall not play with the humidifier. Cleaning and user maintenance shall not be made by children without supervision.
• Before using this humidifier ensures that the voltage of your electricity supply is the same as that indicated on the rating plate of the humidifier.
• Always place the humidifier on a hard, flat and level surface. Avoid exposure to direct sunlight and always keep it away from walls and heat sources such as stoves, radiators, etc. Warning: The humidifier may not work correctly if it is not placed on a level surface.
• Do not insert or remove the electric plug on the humidifier with wet hands.
• If the mains cable is damaged it must be replaced by the manufacturer, its service agent, or similarly qualified person in order to avoid a hazard.
• To reduce the risk of electric shock, do not remove screws. The humidifier does not contain any user-serviceable parts. Please leave all maintenance work to qualified personnel.
• Fill the tank with fresh, distilled or demineralized water. Do not drop any other liquid into water tank or water basin. Do not run the humidifier when there is no water in the tank or the water basin.
• Do not shake the humidifier as this might cause the water spill over into the base of humidifier.
• Never touch the water or components while the humidifier is in operation.
• If there is an unusual smell when it is being used as described in this manual, switch the humidifier off, unplug it and have it examined by your dealer.
• Do not pour hot water into the tank, i.e. at a temperature in excess of 40°C.
• Do not immerse the humidifier or the mains cable or plug in water or other liquids.
• Never scrape the transducer with a hard tool. The humidifier must be cleaned regularly. To do this, refer to the cleaning instructions in this manual.
• If you spill any liquid into the humidifier, it can cause serious damage. Switch it off at the mains immediately. Withdraw the mains plug and consult your dealer.
• Disconnect the humidifier from the power supply when not in use and before cleaning.
• Ensure that the mains cable does not touch any hot surface and that it does not overhang a table edge.
• Never use this humidifier in a room where aerosol products (sprays) are used or in a room or where oxygen is being administered.
• Do not put items of clothing or towels on top of the humidifier. If the nozzle is obstructed, this may cause the humidifier to malfunction.
• When moving the humidifier, lift it by the base and not by the water tank.
• Do not use the humidifier if the air in the room is already sufficiently humid.
• 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.
• Micro-organisms that may be present in the water or in the environment where the appliance is used or stored, can grow in the water reservoir and be blown in the air causing very serious health risks when the water is not renewed and the tank is not cleaned properly every 3 days.
• Keep the appliance out of reach of children. Steam and boiling water may cause burns.
• Never leave water in the reservoir when the appliance is not in use.
• Clean the water every three days.
• Be aware that high humidity levels may encourage the growth of biological organisms in the environment.
• Do not permit the area around the humidifier to become damp or wet. If dampness occurs, turn the output of the humidifier down. If the humidifier output volume cannot be turned down, use the humidifier intermittently. Do not allow absorbent materials, such as carpeting, curtains, drapes, or tablecloths, to become damp.
• Unplug the appliance during filling and cleaning.
• Empty and clean the humidifier before storage. Clean the humidifier before next use.

The following is not considered faulty operation:

• If your water is very hard (containing abnormally high levels of minerals) the humidifier may produce white dust. This is not a malfunction. The solution would be to clean the filter more often or use softer water.
• If you stand very close to the humidifier, you will hear the gurgling sound of water. This is normal.
• The humidifier operates very quietly but it is not completely silent. Noise levels less than 35dB(A) is considered normal.

MAINTENANCE

In case the water is hard, meaning the water contains too much calcium and magnesium, it can cause a “white powder” problem and leave heavy scales on the surface of water basin, transducer, and inner surface of the water tank. Scales on the surface of transducer will let the humidifier work improperly. Empty the tank and refill every third day. Before refilling, clean it with fresh tap water or cleaning agents if required by the manufacture. Remove any scale, deposits, or film that has formed on the sides of the tank or on interior surfaces and wipe all surfaces dry.

Empty and clean the humidifier before storage. Clean the humidifier before next use. Use cold boiled water, or distilled water.

• Clean the transducer, water tank and basin every three days.
• Change the water in the water tank more often to keep it fresh.
• Make sure to pour out water from the water tank and dry everything before storage.

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 BASIN

• Clean the water basin 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 filter under the sun for 4-6 hours to dry, or overnight.
