Inspect coils. Clean when dust accumulation is visible.
In normal use, dust can accumulate and can restrict air-
flow, reducing performance and causing the unit to over-
heat. Use a vacuum cleaner with a brush tool and a soft
cloth to remove any debris. Take care not to damage
any interior components.
To maintain appearance, wipe interior and exterior sur-
faces with a damp cloth. For deep cleaning and a last-
ing, protective shine, use an automotive interior cleaner.
