bad odor
The unit may absorb odors from the environment (such as furniture, cooking,
cigarettes, etc.) which will be emitted during operations.
The unit’s filters have become moldy and should be cleaned.
The fan of the outdoor
unit does not operate
During operation, the fan speed is controlled to optimize product operation.
