️ Common Fixes

• Water leaking from the bottom of the unit — often caused by a missing or cracked drain plug.
• Unit shutting off due to full tank indicator — improper sealing can trigger false water‑level alerts.
• Excess condensation dripping during cooling — replacing the plug restores proper internal drainage.

Installation Tips

• Unplug the AC before accessing the drain area.
• Locate the lower condenser tray drain port on the back or bottom of the unit.
• Remove any old or damaged plug and clean the drain opening.
• Press the new plug firmly into place until fully seated.
• Run the unit and check for leaks after installation.
