Frequently Asked Questions - AD 7971 ADLER

How to clean the ADLER AD 7971 humidifier?

Unplug the device. Empty the water tank and base. Clean the inside of the tank with mild detergent and rinse with clean water. For the atomization transducer, use a cotton swab soaked in citric acid solution to remove scale. Wipe the outside with a damp cloth. Perform this every 3 days.

Why is my humidifier not producing steam?

Check that the device is plugged in and turned on. Make sure the tank has enough water. If the transducer is scaled, clean it with citric acid solution. Also check that the steam flow setting is not at minimum.

Can I use essential oils in the humidifier?

No, the use of additives (essential oils, fragrances, etc.) is prohibited. This may damage the device and void the warranty. Use only distilled or filtered water.

How to disable the beep sound?

Press the power/mist adjustment button for about 3 to 4 seconds. The beep sound turns on or off alternately.

What type of water should I use?

It is recommended to use distilled or filtered water. Tap water may cause white powder. Never pour hot water (max 40°C) or water containing additives.

How often should I clean the humidifier?

Every three days, empty the tank, clean it with fresh water or mild detergent, and remove any deposits. Regular cleaning prevents microorganism growth.

Does the device automatically shut off when there is no water?

Yes, the humidifier is equipped with water shortage protection. When the water level reaches minimum, the device automatically turns off.

Can I leave the humidifier on unattended?

No, it is not recommended to leave the device plugged in unattended. Always unplug it when not in use.

What to do if white powder appears around the humidifier?

White powder is caused by limescale in the water. Use distilled or filtered water. Clean the atomization transducer with citric acid solution to remove deposits.

How to fill the water tank correctly?

Unplug the device. Open the tank lid by pulling the handle upward. Pour cold water (max 40°C) without exceeding the MAX level. Do not pour water directly into the base. Close the lid before plugging in.
