4.4 Drainage Options

Your dehumidifier offers two drainage methods:

  • Manual Drainage (Water Tank): The unit will collect water in its 4.5-liter water tank. When the tank is full, the unit will automatically shut off and an indicator light will illuminate. You must manually empty the tank.
  • Continuous Drainage (Drain Hose): For continuous operation without manual emptying, attach the included 3.28 ft drain hose to the continuous drain port on the back of the unit. Ensure the hose is sloped downwards to a suitable drain (e.g., floor drain, sink) to allow gravity to remove water.
