Problem
Possible Cause
Both the indoor
and outdoor units
emit white mist
When the unit restarts in HEAT mode after defrosting, white mist
may be emitted due to moisture generated from the defrosting
process.
Dust is emitted
from either the
indoor or outdoor
unit
The unit may accumulate dust during extended periods of
non-use, which I will be emitted when the unit is turned on.
This can be mitigated by covering the unit during long periods
of inactivity.
The unit emits
a bad odor
The unit may absorb odors from the environment (such as furniture,
cooking, cigarettes, etc.) which will be emitted during operations.
The fan of the
outtdoor unit
does not operate
During operation, the fan speed is controlled to optimize product
operation.
The unit filters have become moldy and should be cleaned.
