Frequently Asked Questions - UH1800 N'oveen

How do I set the desired humidity level?

Press the HUMIDITY symbol repeatedly to increase the set humidity in 5% steps from 25% to 75% RH. The display shows the current humidity first, then the set value. After 5 seconds, the setting is saved and the display returns to current humidity.

How does the auto mode work?

In AUTO mode, the humidifier automatically determines the optimal humidity based on the current room temperature using a built-in formula. It operates at maximum power until the target humidity is reached, then switches to minimal power. The device checks temperature and humidity every minute.

How do I use the heating function?

Touch the HEATING symbol to activate warm mist. After 10-15 minutes, the mist will be heated. The LED displays the heating symbol. Touch again to deactivate and return to cold mist.

How do I replace the water filter?

Turn off and unplug the unit. Remove the water tank and turn it upside down. Unscrew the filler cap and then unscrew the filter attached to the plug. Remove the old filter from the cap and screw in a new UHF-21/UHF-18 filter. Close the cap, fill the tank with water, and place it back on the base.

How do I clean the transducer?

Apply 5-10 drops of cleaning abluent on the transducer surface and wait 2-5 minutes. Then gently brush off any scale with a soft brush. Rinse the transducer with clean water. For best results, clean the transducer weekly.

What type of water should I use?

It is recommended to use cold boiled water or distilled water to minimize white powder residue and scale buildup. Avoid using hard water high in calcium and magnesium. Water temperature should not exceed 40°C.

Why is there a white powder residue?

White powder is caused by hard water containing calcium and magnesium. Using distilled or boiled water reduces this. If you see residue, clean the transducer and water basin regularly. The built-in ion exchange filter helps but may not eliminate it completely.

How do I set the timer?

Touch the TIMER symbol repeatedly to select from 1 to 12 hours. The LED display shows the remaining time, decreasing by one hour each hour. To cancel, press until 'Co' appears on the display.

What does the plasma function do?

The PLASMA function activates an ionizer to improve air quality. It also controls the tank lighting when pressed and held. Touch the symbol to turn on/off; the LED displays the plasma symbol when active.

What should I do if the unit shows 'NO WATER'?

The auto shut-off has activated because the water tank is empty or very low. Refill the tank with clean water and place it back on the base. The unit will resume operation. If water is not refilled within 15 minutes, the device powers off completely.

DEVICE DESCRIPTION

*Working Principle: Ultrasonic Humidifier uses the ultrasonic high-frequency oscillator to break up water into tiny water particles with the diameter of about 1-5um. The ventilation system blows out this water into the dry air where they evaporate to give the required humidity. The clearly visible smooth and even mist can be seen out of the unit.

\*Features:

• High efficient in humidification with large output.
• Low energy consumption, save 85-90 percent of electricity than normal stream humidifier.
• Automatic control of humidity level.
• Heating function - you can choose whether the mist produced by the device is cold or the humidifier has to heat it.
• Plasma function - improved ionization function.

\*Correct Humidity Level:

What exactly is relative humidity: Relative humidity is the amount of water vapor in the air, expressed as a percentage of the maximum amount that the air could hold at the given temperature. We normally mark it with %RH, like 45% RH. Atomospheric air always contains water vapor, the percentage of which depends on the meteorological conditions. The higher the temperature is the more the air keeps water vapor. Therefore, we use the concept of ‘relative humidity’. When the cold air is heated up to the comfort temperature in winter, the relative percentage of the water vapor falls which means the relative humidity drops. In order to keep a comfortable and health environment at home, we need some artificial addition of water or water vapor to the room air - that’s air humidification.

\*Ideal relative humidity levels:

The most comfortable RH for human being: 45-65% RH

Ideal RH for prophylactic and curative purpose: 40-55% RH

Computer and telecom apparatuses: 45-60% RH

Furniture and musical instruments: 40-60% RH

Library art gallery and museums: 40-60% RH

\* FUNCTIONS

Water filter:

The filter with ion exchange resin can soften hard water and eliminate bacteria.

Before the first use, place the device at room temperature for half hour before commissioning. It is recommended to use the device at 20 °C, relative humidity below 80% RH. Use clean water at temperature of no more than 40^ C.

Check the water container, make sure it is clean and that it has no cracks, which may affect the operation of the device.

Filter replacement (filter color depends on its model)

To change the UHF-21/UHF-18 filter, make sure that the water tank is empty or level water is low enough to allow safe replacement. Before replacing the filter you should also turn the unit off. Turn the tank with the water inlet facing upwards (Fig.1). Then unscrew the filler cap (Fig. 2).
