Plug the power cord into a grounded electrical outlet. Ensure the voltage matches the unit's requirements.
- Drainage Setup (Choose one):
- Manual Drainage (Water Tank): The unit is ready for manual drainage by default. The water tank will collect condensed moisture. When the tank is full, the unit will automatically shut off and an indicator light will illuminate.
- Continuous Drainage (Drain Hose): For continuous operation without emptying the tank, attach the included drain hose to the drainage port on the back of the unit. Route the hose to a suitable floor drain or larger container, ensuring the hose is sloped downwards for gravity drainage.
