Lets play Try to figure out what this (Tech) was thinking. This compressor was installed about 4 years ago after the original suffered a burnout. Suprise, it happened again.
It is a heat pump so was he thinking that the compresor reverses pump direction or maybe the small hot line is the suction line? I know, the reversing valve and the condenser must be located inside the compressor so the liquid line filter is in the correct place. Yah, thats it.
Anyone out there have any guesses?
