Setup
Unboxing and Initial Placement
Carefully remove the dehumidifier from its packaging. The unit is protected by sturdy foam and plastic sheeting. Once unboxed, place the dehumidifier upright on a flat, stable surface. Allow the unit to stand upright for at least 24 hours before its first use. This allows the refrigerant to settle, ensuring optimal performance and preventing potential damage to the compressor.

Operating Modes
- Normal Mode: Operates at a low fan speed. Humidity can be adjusted manually between 35% and 80% RH.
- Turbo Mode: Operates at a high fan speed for rapid dehumidification. Humidity can be adjusted manually between 35% and 80% RH.
- Comfort Mode: Fan speed is low. Humidity is automatically adjusted based on the ambient temperature for optimal comfort. Manual humidity adjustment is not available in this mode.
- Continuous Mode: Fan speed is low. The dehumidifier runs continuously and only stops when the water bucket is full. Manual humidity adjustment is not available.
Smart Humidity Control & Auto-Restart
The dehumidifier features smart humidity control. If your target is 50% RH, the compressor stops when the internal sensor reads 47% RH. The fan runs briefly to use leftover coil cooling, boosting efficiency and reducing waste. When humidity rises to 53% RH, the compressor restarts.
In case of a power outage during operation, the unit will automatically resume its previous settings once power is restored, ensuring continuous operation without manual intervention.
