Issue

Possible causes

the unit is turned on. This can be mitigated by covering the unit during long periods of inactivity.

The unit emits a bad odour

The unit may absorb odours from the environment (such as furniture, cooking, cigarettes, etc.) 
which will be emitted during operations.

The unit’s filters have become mouldy and should be cleaned.

The fan of the outdoor unit
