Setup
1. Unpacking

The dehumidifier comes with five casters (one spare) for easy mobility. Simply press each caster firmly into the designated holes on the bottom of the unit until it clicks into place.
3. Placement Guidelines
For optimal performance, place the dehumidifier in a location where air can circulate freely around it. Ensure there is at least 20 cm (8 inches) of space from walls or furniture on all sides. This unit is suitable for living spaces, garages, basements, bathrooms, and laundry rooms up to 30 square meters (75 cubic meters).

4. Power Connection
Plug the power cord into a standard, grounded electrical outlet. The unit is designed for 220V power supply.
5. Drainage Setup
Your dehumidifier offers two drainage options:
- Manual Drainage (Water Tank): The unit will collect water in its 2-liter internal tank. When the tank is full, the unit will automatically shut off and an indicator will light up. Empty the tank as described in the Maintenance section.
- Continuous Drainage: For continuous operation without needing to empty the tank, attach one of the provided drain pipes (1m or 3m) to the continuous drainage outlet on the back of the unit. Ensure the hose is sloped downwards to allow gravity to drain the water into a suitable drain or container.
Operating Instructions
This section details how to operate your dehumidifier using its intelligent control panel.
1. Power On/Off
Press the Power button to turn the unit on or off.
2. Setting Humidity Level (Automatic Humidity Control)
The dehumidifier features an automatic humidity sensor. You can set your desired humidity level between 40% and 80% relative humidity (RH). The unit will operate until the set humidity is reached and then cycle on and off to maintain it.

5. Child Lock
Activate the Child Lock feature to prevent accidental changes to settings by pressing and holding the Child Lock button for a few seconds.
6. Defrost Function
The unit has an automatic defrost function. If frost builds up on the evaporator coils, the unit will temporarily stop dehumidifying and run the fan to melt the frost. This is normal operation.

When the 2-liter water tank is full, the unit will automatically shut off, and a "Tank Full" indicator light will illuminate. Empty the tank to resume operation.
8. Automatic Restart
In case of a power outage, the dehumidifier will automatically restart with its previous settings once power is restored.
