In relation to blower safety, what must be observed during installation?

Must be placed in a separate room
Must have a circuit breaker nearby
Must allow for adequate airflow
Must be insulated for sound reduction

The correct answer is: Must allow for adequate airflow

During the installation of a blower, ensuring adequate airflow is critical for operation and efficiency. Adequate airflow allows the system to function properly by facilitating optimal heating or cooling. Insufficient airflow can lead to overheating of the blower motor, increased energy consumption, and decreased system performance. It could also cause a range of operational issues, such as poor indoor air quality and inconsistent temperature distribution. While considerations like sound insulation or proximity to electrical components and room placement may have their own importance, they do not directly relate to the fundamental operational requirement of the blower itself. Adequate airflow is essential to maintain the performance and longevity of HVAC systems, making it a primary safety and operational concern during installation.
