Defrost Mode: Automatically engages in low temperatures; compressor pauses, fan continues.
Full Tank Mode: Unit stops; red light illuminates. Empty tank to resume.

Tip: Use AUTO mode for energy savings. Use CONTINUOUS for initial drying of very damp areas.

Maintenance & Cleaning

Unplug unit before any maintenance.

Clean air filter: Remove monthly, wash with mild detergent, rinse, dry completely.
Empty water tank: Pour out collected water; clean tank with mild soap monthly.
