Heat rejected from compressor is dumped in the first condenser, that one at the back.

That condenser it useless!!!

This is after 20minutes when the compressor it's going to normal runing temperature. The heat rejected through the shell is as high as 70%! Sooo air enters at the front, it's taking heat from second condenser, ''washes'' off the compressor, so it has something like 50c and goes to the first condenser at the back to take heat from this one. How can it do that when it has 50 or more degrees???

How much time have you let the unit run? Let it run for 2 or 3 hours take the side off and touch if u can the condensor at the back! it will have 60C or more on all surface!!!

Have you seen big units like 10KW or soo, or bigger? The usual and normal design is: air gets pulled thru condenser and blasts the compresor. There is never hot air from compresor pushed thru condenser, never ,never, never!!!

Everything looks good! and compresor is doomed to have a short life!
