Air Clean Function Button

• This button is used to activate/deactivate the independent air cleaning function with ionization and UV-C lamp.
• When this function is activated, the appliance will operate only as an air purifier, not as a dehumidifier.

Humidity Setting Button

• Setting the desired humidity is possible in the range of 30-80%.

Dehumidify Mode Button

You can choose from 4 modes using this button:

• 1) NORMAL MODE: In this mode, you can set the desired humidity and fan speed.
• 2) AUTO MODE: In this mode, the appliance automatically maintains optimal humidity in the room at a low fan speed. You cannot set the desired humidity or fan speed (settings are automatic).
• 3) CONTINUOUS MODE: In this mode, the appliance continuously dehumidifies at a high fan speed. You cannot set the desired humidity or fan speed (settings are automatic). Caution: If you select this mode, a drain hose (included in the package) must be connected to the appliance. If only the water tank is used, the appliance will turn off when the tank is full.
• 4) LAUNDRY DRYING MODE: This mode is suitable for accelerating laundry drying at a high fan speed. You cannot set the desired humidity or fan speed (settings are automatic).

Anti-Frost Function (Automatic Defrosting)

• If the appliance is placed in an area with a temperature below 18 °C, automatic defrosting may occur (approx. every 25 minutes for about 5 minutes).
• During the defrosting process, the dehumidification and air cleaning process may be interrupted.
• Do not turn off or unplug the appliance during defrosting.

Color Indicator for Humidity Level

The appliance is equipped with a color light indicator for humidity level:

• Blue: Humidity <55%
• Green: Humidity 55-70%
• Red: Humidity >70%

Other Functions

• ALARM: If the water tank is full or removed for more than three minutes, an audible signal will sound, indicating the need to empty the tank and reinsert it.
• AUTO STOP: If the water tank is full, removed, incorrectly placed, or if the room humidity is 5% lower than the set humidity, the appliance will automatically stop dehumidifying.
• MEMORY FUNCTION: In case of a power outage, the appliance remembers the last setting. After switching on again, the appliance will start in the last set mode.
• FULL TANK INDICATOR LIGHT: When this indicator is lit, it means the water tank is full and needs to be emptied, or the tank is removed or incorrectly placed.

Condensate Removal

Emptying the Water Tank

• Before emptying the tank, first switch off and unplug the appliance from the mains.
• Do not remove the water tank immediately after switching off the appliance. Otherwise, water may drip from the appliance.
• Do not connect a drain hose if you are using the tank to collect condensate. If a hose is connected, water will drain from the appliance through this hose instead of into the tank.
• Grip the water tank by both sides and carefully pull it out of the appliance (see illustration). Be careful not to spill the condensate.

[Illustration: Removing the water tank by gripping the handle and supporting the bottom]

Handle

• When emptying the tank, grip it with one hand by the handle at the top and support the bottom part with the other hand.
• Properly reinsert the tank into the appliance.

Continuous Condensate Drainage (CONTINUOUS MODE)

• For continuous drainage, prepare a drain hose, which is part of the package (length 1 meter, outer diameter 10 mm).
• Switch off the appliance and unplug it from the mains.
• Remove the water tank from the appliance.
• Connect the end of the drain hose to the outlet on the appliance and reinsert the water tank into the appliance. Direct the other end of the hose into a larger container (bucket, bathtub, etc.) where the condensate can drain freely. Ensure that the drain hose slopes downwards and is not clogged, blocked, or damaged.
• Before removing the drain hose from the appliance, prepare a container for water that may drip from the outlet.

Cleaning and Maintenance

• Before cleaning, always switch off and unplug the appliance from the mains.
• Do not use volatile substances (e.g., thinners, gasoline, etc.) for cleaning, as this may damage the appliance's surface. Do not use aggressive or abrasive cleaning agents.
• Do not immerse the appliance in water or any other liquid.

Cleaning the Grille and Appliance Body

• Wipe the appliance surface with a soft cloth. If it is dirty, use a cloth dampened with water and a neutral detergent.
• Carefully clean the air outlet grille using a vacuum cleaner or a soft brush.

Cleaning the Filters

• Once a month, carefully clean the carbon and ionization filter using a vacuum cleaner.
• The lifespan of the filters is approximately 1 year, depending on the frequency of use and the environment in which the appliance is used. Replacement filters have the designations DF-005 and DF-006.
• Warning: Do not use the appliance without a filter. Otherwise, dust will be trapped by the evaporator, and the appliance's performance will be impaired.

Cleaning the Water Tank

• Use warm water to clean the tank. If it is dirty, use water with a neutral kitchen detergent and then rinse the tank with clean water. Clean the tank regularly, approximately once a week, to prevent the growth of mold and bacteria.

Pre-use Checks:

• Ensure the air outlet is not blocked.
• The plug and socket are in good condition.
• The air filter is clean.
• The drain hose is not damaged.

Long-term Storage of the Appliance

• If the appliance is not used for a long time, store it according to the instructions below.
• Unplug the appliance from the mains, clean it, and wind up the power cord.
• Ensure the water tank is empty and clean, and the drain hose is disconnected.
• Pack the appliance to protect it from dust and other dirt.
• Store the appliance in a dry and cool place.

Optional HEPA 13 + ACTIVE CARBON FILTER DF-015 Health Kit

• For this model, you can purchase a HEPA 13 + active carbon filter designated DF-015 Health Kit. This filter is placed in the appliance instead of the carbon and ionization filter. The lifespan of this filter is approximately 1 year, depending on the frequency of use and the environment in which the appliance is used. The filter can be cleaned with a soft brush or a vacuum cleaner. This filter cleans the air of dust, mold spores, pollen, mites, and other pathogens.
