IMPORTANT SAFETY INSTRUCTIONS

• Please read this manual carefully before operation and save it for future reference.

• Check the voltage carefully to ensure your home power voltage fits the product

• Ensure the plug exactly inserts to the right socket. Make sure there is a good contact.

• Do not extend the wire.

• Pull out the plug by hand rather than pulling on the wire.

• Do not use the product in dusty, oily or smoky environments, as this may cause electric shock and fire.

• Do not use the product in a wet environment, such as a bathroom, as this may cause electric shock and fire.

• In some cases, such as in areas of high humidity or if the unit is used at maximum capacity, this can eventually cause steam to be emitted, resulting in the area where the unit is situated becoming moist. Regular monitoring of the unit is therefore recommended, and if this occurs, the unit should be stopped.

• Do not use the product near a window, to avoid rain or curtains covering the air inlet or mist outlet. This will cause the temperature to rise and may cause fire.

• Do not place your hands or appliances on top of the product as this may damage the device or result in the device not functioning properly.

• Remove the water tank before moving the device.

• Do not touch the plug or wire with wet hands as this may cause electric shock.

• Do not clean the water sink while the water is still hot.

• Please place the device on an even surface. If the surface is uneven, this may cause the water to flood out.

• Do not clean your machine while it is operating.

• Wait 60 minutes after you turn it off before cleaning the machine.

• Do not expose the machine to sunshine or place it to close to a heater.

• Please disconnect the unit from the electrical socket while you fill it with water, clean the unit, or if the unit is left unused for a long time.

• Do not place metal or easily combustible material close to the air intake or mist outlet areas.

• If the unit is damaged or does not work, please take to a certified repair shop or back to the shop
  from which you bought the unit. Do not perform disassembly or assembly by yourself.

• Care should be taken when using the appliance due to the emission of hot water vapor.

• If the supply cord is damaged, it must be replaced by the manufacturer, the manufacturer’s service agent or similarly qualified persons in order to avoid a hazard.

TRANSDUCER

• The water quality is some places hard so that the transducer surface may create limescale. If so, clean the transducer and heating element surface with mild detergents.
• Add little mild detergent on the transducer surface (More or less depends on the limescale), then infuse water into the sink to soak the sink fully for 10-15 min.
• Clean with brush until limescale disappear.
• Clean twice with water.
• Don’t clean transducer with any metal or a brsive materials or scrape it to avoid damage.

WATER SINK INSIDE

• Remove the water from the sink, clean off the scaling with a brush, then wipe with a damp cloth.
• Rinse it with water.
• Do not pour water directly into the sink when cleaning the water sink.
• To avoid damaging the transducer, do not use acid detergents to wash the water sink inside.

WATER TANK INSIDE

• Clean water tank inside and water sink twice per week if using the machine frequently.
• Use a soft cloth and wipe down the side of water tank if it has limescale.
• If there is dirt on the inside of the tank wall, this may be removed by cleaning with a mild detergent. Clean off the detergent completely afterwards.
• Do not put acid, alkalescent or bleach detergents into water tank to avoid damage.

BODY AND WATER TANK OUTSIDE
