Wait three (3) minutes for capacitors to discharge to safe voltage levels. Failure to do so mayresult in personal injury or death. Note: Darkened display LEDs are not an indication of safe voltage levels.CAUTION: It is the sole responsibility of the installer to verify the operating voltage of the fan system prior to installation! Itis also mandatory that the installer verify that airfoils, motor hub assemblies, and fan controllers are matched properly at thetime of installation, especially if multiple fan systems will be installed.CAUTION: An incorrectly installed controller can result in component damage or reduction in the fan’s life. Wiring orapplication errors such as under-sizing the controller, incorrect or inadequate AC supply, or excessive ambient temperaturesmay result in a malfunction of the fan system. Verify correct voltage, phase, and horsepower before beginning installation!WARNING: Exercise caution and common sense when powering the fan.
