PRECAUTIONS AND GUIDELINES

The NuTone IMA-4406 master station has been designed for ease of installation. Please read and follow ALL installation instructions, guidelines and precautions. Any deviation from these instructions or miswiring combinations may result in unit failure and void of warranty.
