  • When setting humidity is 10%RH~15%RH higher than current humidity, mist output speed will run by the middle (the third) speed.
  • When setting humidity is 15%RH higher than current humidity, mist output speed will run by the highest (the fifth) speed.
  • When current humidity is higher than setting humidity, humidifier will turn into sleep state. Once current humidity is 3%RH lower than setting humidity, humidifier will re-work in previous working mode till water shortage.

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 EN

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. 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.
