Recommended cleaning frequency: Every two weeks, or more often depending on usage and air quality.
Draining Accumulated Water:
During dehumidification or cooling, water will accumulate inside the unit. The unit has a self-evaporative system, but in high humidity conditions, manual draining may be necessary. Refer to your printed manual for specific draining procedures, which typically involve a drain plug at the bottom or back of the unit.
Cleaning the Unit Exterior:
Wipe the exterior of the unit with a soft, damp cloth. Do not use harsh chemicals, abrasives, or solvents, as these can damage the surface.
