Quick question about flow direction.
First off, sorry if I'm posting this in the incorrect place.
Secondly I'm new to the industry, about 2 months in actually, and I just recently worked on my first water-source heat pump.
Upon digging into the unit I found that the inlet and outlet lines on the unit were reversed. Supply line from the loop was being feed into the outlet of the unit, and return loop was hooked up to the inlet on the unit. I'm curious as to what symptoms would show due to this incorrect installation, if anything serious?
If I recall correctly the unit is a McQuay single stage horizontal, 3/4 ton.
I've got some more detailed information about the units/building if needed.
