Easy to install, just plug it in to a fan input and set the ch fan speed to 100% in the bios options to avoid problems with the unit and you can also change the direction of the coolant inlet from right to left (default) or left to right depending on where you place it on the toilet circuit.
Advantages: very easy to install.
