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.

•Observe all local building regulatory codes in your area.

•All screw terminals at the master and remote stations must be secure.

•Observe all color code connections of wires when connecting the remote stations to the master.

•The IMA-4406 is designed to be installed with only NuTone specified wire. No other wire should be used. The use of wire other than NuTone wire will void all NuTone warranties and may result in faulty installation and improper operation.
