4. Setup
Proper setup is crucial for the efficient operation of your portable air conditioner.
4.1. Placement
Place the unit on a flat, stable surface. Ensure there is at least 30 cm (12 inches) of space around the unit for proper airflow. The unit is ideal for cooling rooms up to approximately 20 square meters.
4.2. Exhaust Hose Installation
The portable air conditioner requires an exhaust hose to vent hot air outside. This prevents the hot air from recirculating into the room, which would reduce cooling efficiency.
- Attach one end of the exhaust hose to the air outlet on the back of the unit.
- Extend the exhaust hose to a window or a suitable opening.
- Use the provided window sealing kit to secure the other end of the hose in the window, ensuring a tight seal to prevent hot air from entering.
