Answer 1

The installation of a rooftop package unit requires field piping to be done, unlike packaged air-conditioning equipment. This process involves several steps and should be done by professionals.

Step-by-step explanation:

The installation of a rooftop package unit requires field piping to be done.

This process involves several steps and should be done by professionals to ensure the unit is installed correctly and safely.
