For maintenance-free use, you can attach a drainage hose to the upper port to channel water continuously into a floor drain or bucket.
Always ensure the rubber plugs are tightly resealed after draining to prevent leaks on your floor when the unit restarts.

The internal tank rarely needs emptying in standard cooling mode because the unit automatically evaporates most moisture through the exhaust hose.
In high humidity or dehumidifier mode, the unit will stop and display a "Full Water" code when the internal reservoir is maxed out.
To empty it, place a shallow pan under the bottom drain port at the back, remove the rubber plug, and let the gravity-fed water flow out.
