3. Setup and Installation
3.1 Unpacking
Carefully remove the dehumidifier from its packaging. Inspect the unit for any shipping damage. Retain the packaging materials for future transport or storage.
3.2 Placement
Place the dehumidifier in a location where the humidity is highest and air circulation is good. Ensure there is at least 8 inches (20 cm) of space around the unit for proper airflow. The unit is equipped with 360° casters for easy movement.

3.3 Drainage Options
The Kesnos dehumidifier offers two methods for water removal:
- Manual Drainage (Water Tank): The unit collects water in a 0.58-gallon (2.2 L) internal water tank. When the tank is full, the unit will automatically shut off and an indicator light will illuminate. Carefully remove the tank from the front of the unit and empty the collected water.
- Continuous Drainage (Drain Hose): For continuous operation without manual emptying, attach the included 6.6 ft (2 meter) drain hose to the continuous drain port on the back of the unit. Ensure the hose is sloped downwards to allow gravity to drain the water into a suitable floor drain or container. A standard garden hose (not included) can also be used.

4. Operating Instructions
4.1 Control Panel
The dehumidifier features an intuitive control panel with a front-facing digital display that shows the current humidity level. The display can be turned off while the unit continues to operate.

4.2 Power On/Off
Press the Power button to turn the unit on or off. The unit has a power-off memory restart function, which means it will resume operation with the last settings after a power interruption.
4.3 Setting Desired Humidity
Press the Setting button to adjust the desired humidity level. The humidity can be set between 30% and 80% Relative Humidity (RH). The unit will operate until the ambient humidity reaches the set level, then cycle on and off to maintain it.
4.4 Operating Modes
Press the Mode button to cycle through the available operating modes:
- Standard Mode: The unit operates based on the set humidity level and fan speed.
- Drying Mode: Provides maximum airflow to assist in drying clothes or other items.
- Continuous Mode: The unit will operate continuously regardless of the ambient humidity level, ideal for very damp conditions.
4.5 Fan Speed
Press the Speed button to select between two fan speeds (Low and High). Higher fan speed results in faster dehumidification.
4.6 Timer Function
The 24-hour timer allows you to program the unit to turn on or off automatically after a set period. Press the Timer button and use the setting buttons to adjust the desired duration.
4.7 Auto Defrost
The dehumidifier is equipped with 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 ensures efficient operation in cooler environments.

5. Maintenance
Regular maintenance ensures the longevity and efficient operation of your dehumidifier.
5.1 Cleaning the Air Filter
