Condensate Removal
Emptying the Water Tank
- Before emptying the tank, first turn off and unplug the appliance from the mains.
- Do not remove the water tank immediately after turning off the appliance. Otherwise, water may drip from the appliance.
- Do not attach a drain hose to the appliance if you are using the tank to collect condensate. If a hose is connected, water will drain from the appliance through the hose instead of into the tank.
- Grip the water tank by both sides and carefully remove it from the appliance. Be careful not to spill the condensate.
- When emptying the tank, grip it with one hand by the handle on the top part and support the bottom part with the other hand.
- Reinsert the tank correctly into the appliance.
Condensate Removal Using a Drain Hose (CONTINUOUS MODE)
- For continuous drainage, prepare the drain hose, which is included in the package (length 1 meter, outer diameter 10 mm).
- Turn off and unplug the appliance 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 to a larger container (bucket, tub, etc.) where the condensate can drain freely. Ensure that the drain hose points 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
- Always turn off and unplug the appliance from the mains before cleaning.
- Do not use volatile substances (e.g., thinners, gasoline, etc.) for cleaning, to avoid damaging 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 Casing
- Wipe the appliance surface with a soft cloth. If it is 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
- Clean the carbon and ion filter monthly using a vacuum cleaner.
- Filter lifespan is approximately 1 year, depending on the frequency of use and environment. Replacement filters are designated DF-005 and DF-006.
- Note: Do not use the appliance without filters. Otherwise, dust will accumulate on the evaporator, worsening the appliance's 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.
- Ensure the air filter is clean.
- Ensure the drain hose is not damaged.
Long-term Storage
