If you refer back to his 09/26 post:
"It has a plug that has 4 wires going to it. It's screwed into the a/c line and if it needs to be cleaned you can just unscrew it from the line, and don't worry about refrigerant leaking out, there is a schrader valve that prevents it from coming out. You can also leave it in if you find that it is dirty but it's a lot easier to clean while it's out."
