Your Copeland Scroll Compressor is worth what you paid for the whole box!
I'm really interested in what the coaxial HXs look like. If there's any way that you can snake your hand back in there and just snap away blind, you're bound to come up with a few good pix.
I don't know how you want to use this, but if you are intending to put it in your house, you should know that heat pumps like yours, that distribute their heat via central air ducts, have a coil temperature that is substantially lower (120F-ish) than gas or oil fired heat (140F to 160F)... it's just the nature of the beast. Because of this, they need to have air running much more frequently (sometimes almost constantly) and also the volume of air needs to be greater.
A lot of conversions from oil-fired to heat pump central air do not install larger ducts to allow larger volumes of air to circulate quietly (the companies don't want to lose the bid), therefore there is air duct background noise almost all the time.
This happened to my girlfriend, but she paid so much money for the system and installation, she just pretends the noise isn't there... but the noise is there, almost all the time.
So, if you haven't already installed ducts, you should install over-sized ducts, and over sized vents.
I'm not a HVAC guy and I can't specify how much bigger your ducts & vents need to be, but I do know that this is an issue.
There is a very similar issue with hydronic heating... oil & gas fired boilers easily produce high temperatures (140F to 160F), and the hydronic industry has adopted practices adapted to the high boiler heat.
But heat pump hydronic heaters will not reach the same high temperatures (around 120F) so to work really well, different practices need to be used (larger PEX, closer PEX spacings,
higher flow rates).
Why go to all this hassle?
Because heat pump heating is very much cheaper than either gas or oil.
