Question about Furber Nuvola

The compressor is in the outside unit, that's also why it's heavier. Laying it on it's back i.e. on a roof is therefore not good to do.

I cannot answer this question because it has not yet been delivered to me. However, I would also be interested to know whether the unit may be operated indoors in the lateral position. Because the opening of the window does not allow it otherwise. Unfortunately, this is the only possibility due to the short cable.
