Before installing the Amana PTC094G35AXXX DigiSmart series PTAC air conditioner unit, a project survey form is required to ensure proper installation and avoid potential issues. The survey form captures important information about the property, including the location, electrical and mechanical specifications, and building structure. This information is used to determine the appropriate location and orientation of the PTAC unit, as well as the necessary electrical and mechanical requirements. The project survey form also includes questions about the intended use of the unit, such as whether it will be used for cooling, heating, or both. Through the information obtained from the form, the installation process is streamlined, allowing for a smooth and efficient process, providing optimal efficiency and performance.
