- Locate and remove the air filter from its slot (refer to product diagram for location).

Drainage:
The unit collects condensate water during operation, especially in Dry (dehumidifier) mode. It has two drainage holes (bottom and middle) for flexible water management.
- For continuous drainage (recommended for Dry mode), connect the provided drain hose to the appropriate drain port and direct it to a suitable drain or container.
- If not using continuous drainage, the internal water tank will collect water and the unit will stop operating when full. Drain the tank manually by removing the drain plug and allowing water to flow out.
