Mode Setting Button (DEHUMIDIFY MODE)

• This button allows you to select from 4 modes:
• 1) NORMAL MODE: In this mode, you can set the desired humidity and fan speed.
• 2) AUTO MODE: The appliance automatically maintains optimal room humidity at a low fan speed. Desired humidity or fan speed cannot be set (automatic settings).

• MEMORY FUNCTION: In case of a power outage, the appliance remembers the last setting. Upon restarting, it will resume the last set mode.
• FULL TANK INDICATOR LIGHT: If this indicator is lit, it means the water tank is full and needs to be emptied, or the tank is removed or improperly placed.

Condensate Removal

Emptying the Water Tank

• Before emptying the tank, turn off and unplug the appliance.
• Do not remove the water tank immediately after turning off the appliance, as water may drip.
• Do not connect a drainage hose if you are using the water tank to collect condensate. If a hose is connected, water will drain through the hose instead of the tank.
• Grasp the water tank by both sides and carefully remove it from the appliance (see illustration). Be careful not to spill the condensate.
• When emptying the tank, hold it with one hand by the handle at the top and support the bottom with the other hand.
• Place the tank back into the appliance correctly.

Condensate Drainage via Drainage Hose (Continuous Mode)

• For continuous drainage, prepare the drainage hose included in the package (1 meter length, 10 mm outer diameter).
• Turn off and unplug the appliance.
• Remove the water tank.
• Connect the end of the drainage hose to the outlet on the appliance and return the water tank to the appliance. Direct the other end of the hose to a larger container (bucket, tub, etc.) where condensate can drain freely. Ensure the drainage hose points downwards and is not blocked, obstructed, or damaged.
• Before removing the drainage hose from the appliance, prepare a container for any water that may drip from the outlet.

Cleaning and Maintenance

• Always turn off and unplug the appliance before cleaning.
• 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 Casing

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

Filter Cleaning

• Once a month, carefully clean the carbon and ionization filters using a vacuum cleaner.
• Filter lifespan is approximately 1 year, depending on usage frequency and environment. Replacement filters are labeled DF-005 and DF-006.
• Note: Do not use the appliance without filters. This will lead to dust accumulation in the evaporator and reduced appliance performance.

Cleaning the Water Tank

• Use warm water to clean the tank. If 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 mold and bacteria growth.

Pre-Use Checks

• Ensure the air outlet is not blocked.
• Check that the plug and socket are in good condition.
• Verify the air filter is clean.
• Ensure the drainage hose is not damaged.

Long-Term Storage

• If the appliance will not be used for an extended period, store it according to the following instructions:
• Unplug the appliance, clean it, and coil the power cord.
• Ensure the water tank is empty and clean, and the drainage hose is disconnected.
• Pack the appliance to protect it from dust and other contaminants.
• Store the appliance in a dry and cool place.

Optional HEPA 13 + Active Carbon Filter DF-015 Health Kit

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