“This unit head is easy to install as long as you have access to it. Just be sure to lower your thermostat so the heat does not come on. The power to the Power Head has to be OFF before you disconnect the wires. Make sure you replace the wires in exactly the way you removed them. Also, the manual override lever on the Power Head has to be in the up position, like in the diagram, before you remove the Power Head. The job took me about 15 minutes.”
