Last time we looked at Xringer’s installation of the indoor unit. Next comes installing the outdoor unit. Its pretty straight forward, so lets dive right in.
The first step was to start connecting the lines outside. Xringer had already run the conduit for the lines, so he just had to connect them up to the line set that goes to the indoor unit.
After that, he tucked the outdoor line set into the conduit and positioned the lines so they were close to where the outdoor unit will sit. This does require bending the copper line which isn’t easy to bend considering the larger tubing is 5/8″. A tubing bender would come in handy to make this easier.
Of course the next step is mounting the outdoor unit. A few screws into the concrete with an aluminum bar through the feet of the unit keeps things held down.
Next up was to connect the refrigerant lines to the outdoor unit. This was quite easy as the lines didn’t need to be shortened. If Xringer had shortened them, he would have had to re-flare the ends of the tubing since the connectors use flared ends.
The last thing to hook up with the outdoor unit was the wiring. A few screw connections takes care of it all.
That is what it takes to physically install the indoor and outdoor units. As we move along in the series, we’ll look at pressure testing the units/connections and adding refrigerant to the system.
