Every evaporative cooler supported on an aboveground platform must be elevated from the ground by at least how many inches?

  1. 12 inches

  2. 18 inches

  3. 24 inches

  4. 30 inches

The correct answer is: 12 inches

The requirement for elevating evaporative coolers serves multiple practical purposes, primarily related to maintaining efficiency, ensuring proper drainage, and preventing water damage or pooling around the unit. Elevating the cooler by at least 12 inches above the ground helps to ensure that water can properly drain away from the unit, reducing the risk of rusting or corrosion caused by prolonged exposure to standing water. Additionally, this elevation assists in preventing debris, dirt, and other contaminants from entering the unit, which can hinder its performance and lead to maintenance issues. It's also relevant in areas where local building codes specify minimum elevation heights to avoid flood risks, enhance airflow, and promote better access for maintenance and service tasks. Understanding the minimum elevation requirement helps HVAC professionals ensure their installations comply with safety and performance standards, contributing to the longevity and reliability of the evaporative cooler.
