The ceiling unit is now connected to the outdoor unit with both the line set and electrical cable. 
The water outlet is connected to a hose that runs down to under the house.
The ceiling plate is also installed.
As you can see, the air filter is in the down position; it has a built in lift that lowers the filter for easy cleaning access. My ceiling isn’t that high, but it’s a cool feature.
Outside, the line set and electrical cables are also installed.
The only thing left is to open the valve on the condenser to release the refrigerant, but I probably won’t do that until I have also installed the master bedroom indoor unit.
And then after a final check for leaks, the pipes can be wrapped up to prevent sweating.
Hurrah!!! Good job B!!
Thanks! Having a beer to celebrate đș
Looking at the piping: more closely; is the one on the front copper? Does it contain refrigerant? Donât the ridges increase the outside surface, leading to an increased surface/contact to warm / hot air?? (Do mind I am not a technician nor physicistđ)
To avoid what they call âSweatingâ all lines containing refrigerant are wrapped in insulation. That wasnât done when this picture was taken as I still wanted to check for leaks after running both indoor units.
