3. Setup and Installation
3.1 Unpacking
Carefully remove the air conditioner from its packaging. Retain the packaging for future storage or transport. Check for any damage during transit.
3.2 Placement
Place the unit on a flat, stable surface. Ensure there is at least 20 cm of space around the unit for proper airflow. The unit is equipped with 360° multi-directional wheels for easy movement.
3.3 Exhaust Hose and Window Kit Installation
The portable air conditioner requires an exhaust hose to vent hot air outside. This is crucial for effective cooling and heating.
- Attach one end of the exhaust hose to the air outlet on the back of the unit.
- Extend the exhaust hose to the nearest window.
- Install the provided window kit into the window opening. This kit helps seal the window around the exhaust hose to prevent outside air from entering.
- Secure the other end of the exhaust hose to the window kit adapter, ensuring a tight seal.

3.4 Drainage Setup
During dehumidification or cooling modes, water will accumulate inside the unit. The unit has a dehumidification capacity of up to 28 liters per day. You can choose between manual drainage or continuous drainage:
- Manual Drainage: When the internal water tank is full, the unit will stop operating and an indicator will light up. Turn off the unit, place a suitable container under the drainage port, and remove the drain plug to empty the water. Replace the plug securely after draining.
- Continuous Drainage: For continuous operation, especially in high humidity, connect a drain hose (not included) to the continuous drainage port and direct it to a floor drain or a larger container.
