Indication Light Twinkle Related to Malfunction Code:
● The following phenomena are not unit malfunctions:
Some odorous gas blows from the unit, because the unit sucks cigarette smoke and smell from
cosmetic, furniture and electric machine. We always hear fizzle from the unit when starting stopping
the unit, as the refrigerant flows in the unit. Sometimes we may hear click noise, because the
temperature change causes other parts expanding with heat and contracting with cold. The outdoor
unit generates buzz because of loading/unloading the digital scroll compressor.
