5. Operating Instructions
5.1 Power On/Off
Press the Power button on the control panel to turn the unit on or off.
5.2 Setting Humidity Level
In Dehumidification (DEHU) mode, you can set the desired humidity level between 30% and 80% relative humidity. The unit will automatically operate to maintain this level, turning off when the target is reached and restarting if humidity rises.
5.3 Operating Modes
Press the Mode button to cycle through the available operating modes:
- DEHU (Dehumidification) Mode: The unit operates to reach and maintain your set humidity level.
- DRY (Clothes Drying) Mode: This mode is designed for quickly drying laundry. The unit operates continuously at high fan speed to remove moisture from clothes.
- CONT (Continuous) Mode: The unit operates continuously regardless of the ambient humidity level. This is useful for severe humidity conditions.

6. Drainage Options
Your dehumidifier offers two methods for water drainage:
6.1 Manual Drain (Water Tank)
Condensed water collects in the removable 2.5-liter water tank. When the tank is full, the unit will automatically shut off, an alarm will sound, and a full water icon will flash on the display, indicating that the tank needs to be emptied.

6.2 Continuous Drain
For continuous, hands-free operation, you can connect a drain hose (included) to the continuous drainage outlet. This allows water to drain directly to a floor drain or suitable receptacle, eliminating the need to manually empty the water tank.
