Important: The Electric Fan Assembly is built using a High Output two speed motor. If you choose to operate the fan using both speeds, two switching devices or a Derale Dual Fan Controller Part # 16788 / 16789 must be used.

We recommend using two thermostats therefore activating the low speed at an earlier temperature then the high speed. Please visit www.derale.com for available thermostat options or visit your local retailer. Note: When purchasing a thermostat always consider the maximum amp draw. Some thermostats are not designed to properly handle higher amperage fans.
