This dehumidifier is designed to remove excess humidity from the air. Before using the device, ensure it has been standing upright for at least 1 hour after transport. Maintain a minimum clearance of 50 cm in front of the unit to ensure proper air outlet. The device is intended for indoor domestic use only.
Description and accessories
The unit features a control panel, water level indicator, removable condensate tank, and a lifting handle. It includes an air intake grille, a silver ion air filter, an air outlet grille, a 2m condensate drainage hose, and casters for mobility.

Safety instructions
- Do not touch the appliance or plug with wet hands.
- Always unplug the device by gripping the plug, not the cord.
- Do not use extension cords.
- Ensure the device is properly grounded.
- Do not use the appliance in laundry rooms or outdoors.
- Keep the device away from heat sources and flammable substances.
- Do not obstruct air intake or outlet grilles.
Installation
Position the unit in the room to be dehumidified. Ensure at least 50 cm of space in front and 5-10 cm behind the unit.


Condensate drainage
Tank drainage: Condensate is collected directly in the removable tank.
Continuous drainage: For long-term operation, unscrew the continuous drainage cap, remove the rubber stopper, and attach the provided rubber hose. Ensure the hose does not rise higher than the outlet nozzle and is not kinked.
Caster installation
To install the casters, unplug the unit and empty the tank. Remove the rubber stoppers from the base (use pliers if necessary) and insert the casters into the holes.
Operating modes
Dehumidification Mode: Allows setting the desired humidity level (30% to 80%) and fan speed (MIN/MAX). The unit stops when the target humidity is reached.

Dry Mode: Operates at maximum power for rapid dehumidification. Humidity and fan speed cannot be adjusted.
Smart Mode: Automatically selects optimal settings based on ambient conditions.
Ventilation Mode: Operates as a fan only. Fan speed can be adjusted.
Cleaning and maintenance
Always unplug the unit before cleaning. Clean the exterior with a damp cloth; do not use solvents or insecticides. The silver ion air filter should be cleaned regularly (weekly if used constantly). Extract the filter laterally, vacuum dust, or rinse with lukewarm water (max 40°C). Let it dry completely before reinserting.

Troubleshooting
If the unit does not dehumidify, check if the filter is clogged, the room is too large, or the humidity setting is too high. If the unit does not start, wait 3 minutes for the safety device to reset. If the display shows error codes, check the tank position or ambient temperature.
