6. Drainage Options

Your Midea dehumidifier offers multiple ways to remove collected water:

A. Manual Emptying (1.6 Gallon Bucket)

When the water bucket is full, the unit will automatically stop operating and an indicator light will illuminate. Carefully remove the bucket from the side of the unit, empty the water, and reinsert the bucket firmly until it clicks into place. The unit will resume operation.

B. Continuous Gravity Drainage

For continuous operation without emptying the bucket, you can connect a standard garden hose (not included) to the continuous drain outlet at the back of the unit. Ensure the hose is sloped downwards to allow gravity to drain the water into a floor drain or suitable receptacle.

C. Built-in Pump Drainage

The integrated pump allows water to be drained upwards or over a longer distance, providing more flexibility in placement. Connect the included drain hose to the pump outlet. Route the hose to a sink, drain, or window. The pump will automatically activate when the water level in the internal reservoir reaches a certain point, pushing the water out through the hose.

7. Maintenance

Regular maintenance ensures optimal performance and longevity of your dehumidifier.

A. Cleaning the Air Filter

The air filter should be cleaned every two weeks or more frequently depending on usage and air quality. A dirty filter can reduce efficiency and cause the unit to work harder.

  1. Turn off the dehumidifier and unplug it from the power outlet.
  2. Locate the filter access panel (usually on the back or side).
  3. Remove the filter.
  4. Wash the filter with warm, soapy water. Rinse thoroughly.
  5. Allow the filter to air dry completely before reinserting it. Do not use a dryer or direct heat.
