Question about De'Longhi Pinguino PAC EM82

The diameter of the exhaust pipe is not specified in the internal data nor in the official resources consulted.
For this type of mobile packaged air conditioner, the included window kit usually includes a standard hose of about 12-15 cm in diameter, but the exact measurement is not given in the available official documentation.
If you need the exact measurement, I suggest you consult the enclosed user manual or contact De'Longhi customer service directly.
I am not completely sure about the answer, because the information is not in the provided data.
