Indoor unit cannot deliver air.
Moisture on air outlet vent.
If unit is running under the high humidity for
a long time, the moisture will be condensed
on the air outlet grill and drip off.
In HEAT mode, when the temperature of
indoor heat exchanger is very low, that
will stop deliver air in order to prevent cool
air. (Within 3min)
In HEAT mode, when the outdoor temperature
is low or high humidity, there are much frost
be formed on the outdoor heat exchanger,
that the unit will automatically defrost, indoor
unit stop blowing air for 3-12 mins. During the
defrosting, there is water flowing out or vapor
be produced.
