• Open the drain valve. The unit has a small lever or button on the front panel. Slide or press it to open the valve, allowing water to flow out.
• Let the water run. Allow the reservoir to empty completely. If the unit has a built‑in pump, it will push water through the pipe; if not, gravity will do the job.
• Close the valve. Once the reservoir is empty, close the drain valve to prevent backflow.
• Check for leaks. Inspect the drain line and connections for cracks or loose fittings. Tighten or replace as needed.
• Clean the drain line. Periodically flush the line with a mild vinegar solution to remove mineral buildup that can clog the pipe.
• Reset the unit. After draining, power the unit back on. The display may show a “Drain Complete” message; if not, simply restart the AC.

Tip: Keep the drain line angled at least 5° downward to avoid standing water, which can lead to mold growth. If you live in a humid climate, consider using a dehumidifier in the same room to reduce condensation buildup.

If you notice a persistent leak or the unit fails to drain, contact support. Never block the drain port with a towel or cloth; this can cause overflow and potential electrical hazards. Always use a container that can hold at least 1 gallon of water, as some units produce up to 0.5 gallons per hour during peak operation.

If you notice a foul odor, it may indicate bacterial growth in the condensate reservoir; clean the reservoir with a mild bleach solution (1 tsp per gallon of water) and rinse thoroughly. After cleaning, dry the reservoir completely before reassembling to prevent mold.
