It seems the Sanyo has dual cap tubes, plus and Electric expansion valve.

I've been looking the diagrams, trying to get a little understanding of the components used in the Sanyo.
That old Chrysler Air Temp was still working, but was too dinged up after removal from the wall to be saved.
I knew it's days were numbered. It was a window unit that got mounted in a hole in the wall.
When I installed it, I didn't plan on ever removing it.
It was turned into the Recyclers shortly after it was replaced.
But the backup Kenmore is a true slide-in wall unit and it can be uninstalled
and kept in good enough condition to sell or re-use somewhere.
This is one you can pull half way out and oil the motor every spring..
I'm pretty sure it's gonna stay put until the end of next summer,
while I see if the Sanyo is as good as I think it is.
The Sanyo has heated my home 24-7 for almost 3 weeks and it hasn't hiccuped once.
