WIRING OPTIONS
IMPORTANT: Due to the high amperage of each individual RAD fan on the Dual RAD Fan Assembly, each fan MUST be switched*
individually. Failure to use two different switching devices could cause damage to your vehicle and/or your new Electric Fan Assembly.
* Switched - Utilizing an automotive rated thermostat or manual switch
There are a few options on how to activate (turn on) your new Electric Fan Assembly.
1. Manual Switch - Install a switch in the passenger compartment and turn on Electric Fan as desired.
2. Electric Fan Thermostat Switch
A. Adjustable Thermostat - Allows an adjustment range for you to determine optimal turn on temperature.
B. Pre Determined Temperature - Thermostat has a pre determined temp. from the factory that determines turn on temp.
We recommend using two thermostats therefore activating Fan #1 at an earlier temperature than Fan #2. This will help spread
the major amp draw on your vehicles electrical system. Please visit www.derale.com for available thermostat options or visit
your local retailer.
Important: When purchasing a thermostat always consider the maximum amp draw. Some thermostats are not designed to
properly handle 25 amps.
Note: When installing the Electric Fan with a Thermostat always follow manufacturer's instructions for specific details. In some
cases you will not need the supplied relay harness.
