Sunpentown Portable AC units are equipped with an advanced condensation removal
system: Self-Evaporating Technology (except WA-9000E, WA-1000E & WA-1205E). When running AC mode,
this technology recycles the water condensation to cool off the cooling coils,
then evaporates the water out with the exhaust air. This results in increased
energy efficiency, cooling performance and reduces the need to empty the water
tank. Under extreme humid conditions, the water condensation may collect faster
than the unit can recycle. Should the built-in water tank becomes full, the
compressor will automatically shut-off and water full indicator will blink.
At this time, water should be emptied, which is a simple process.
