  • 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.

  • 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, nonindustrial, 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.

  • Warning: 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.

  • Empty the tank and refill every third day. Before refilling, clean it with fresh tap water or cleaning agents if required by the manufacturer. Remove any scale, deposits, or film that has formed on the sides of the tank or on interior surfaces, and wipe all surfaces dry

PLACEMENT

  • Place the product on firm, flat surface.
  • The humidifier should be placed on flat horizontal surface and keep it steady.
  • Do not place the product near or close to any heat sources.
  • The humidifier should be far away from any heat sources, such as stoves or fire places. Do not expose the product to direct sunlight.
  • Do not place the product near or close to furniture or electric appliances.
  • The mist outlet from the humidifier should not be directed towards furniture and the electronic appliances, to avoid damage.
  • Particles in water, such as calcium, can be part of the vapour and be deposited on objects in the vicinity.
  • It is recommended that the unit be placed on a table or other surface at least 70 cm above the floor level, to ensure that the vapour will be optimally distributed throughout the room.
  • Air draft and temperature changes can impact the distribution of the vapor. To avoid water damage it’s recommended to always check for moist accumulations on the floor or other nearby surfaces.

The following is not considered faulty operation:

  • 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

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 surface of water basin, transducer, and inner surface of the water tank. Scales on the surface of transducer will let the humidifier work improperly.

Use cold boiled water or distilled water.

Empty the tank and refill every third day. Before refilling, clean it with fresh tap water. 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. Make sure all parts are died completely. Clean the humidifier before next use.

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

  • If the scale covers the security switch, drop some citric acid on it and let it sitfor 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
