Before attempting the installation, please read through these instructions in their

only. Connecting the receiver wiring to 120/240 VAC power will result in
equipment damage and may void warranty.
• Installation methods must comply with all applicable national and local
building codes. If you are unsure about proper wiring practices, have a
qualified contractor perform the installation for you.
• The Receiver cover should always be used when the Receiver is installed
outdoors.

inside a rain gutter.
