 Hey everyone, we're back and we're going to show you how to install and mount the Geos CO2 combo smoke and CO detector. It's very easy. As you can see, we've already pre-mounted our anchors and screws in place there on the ceiling. What we're going to do next is we're going to go ahead and slide the back plate into place by putting it into the holes there and then sliding. Once you've slid it into the skinnier part, feel free to tighten wherever you see fit, but make sure that it's out of the big hole there. Tighten down just like so, as Technician Sal here is doing, and you can do that to both until the back plate is seated firmly there. Once it is firmly seated, all you're going to be doing is just taking the actual CO and smoke device and connecting it to the base according to the grooves, and then twisting it clockwise to snap it into place. Technician Sal here demonstrates properly, and just like that, voila, the CO2 is installed.
