Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your unit.
Cleaning the Air Filter

The reusable filter can be easily cleaned weekly under a faucet.
The unit features a reusable, washable filter. It is recommended to clean the filter weekly, or more frequently if the unit is used in a dusty environment. To clean, remove the filter from the back of the unit, rinse it under running water, and allow it to air dry completely before reinserting.
Draining Condensed Water
During cooling and dehumidifying operations, water will condense inside the unit. The unit has an auto-evaporation system, but in high humidity conditions, the internal water tank may fill up. When full, the unit will stop operating and display an error code. Connect the drain hose to the continuous drain port for continuous operation, or manually drain the tank when indicated.
General Cleaning and Storage
Wipe the exterior of the unit with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners. Before long-term storage, ensure the unit is completely drained of water and the filter is clean and dry. Store the unit in a cool, dry place.
