1. Optimum performance will be achieved within these operating temperatures.
2. When the unit operates above or below these conditions for a long time, system diagnostics may detect a
malfunction and the unit will not operate properly.
3. Room relative humidity - less than 80%. If the air conditioner operates outside this range, the surface of the air
conditioner may attract condensation. Please set the air flow louver to its maximum angle and set HIGH fan mode.

strongly recommend keeping the unit plugged in at all time to ensure smooth ongoing performance.
