Here's a couple of Coleman installations done by someone who really shouldn't be installing equipment. The top is by a handyman for an office building. Hope the landscaper doesn't miss his edging that's TRYING to level the unit. Too bad the guy didn't bring a 45 degree copper fitting so his unit could be installed properly. The owner of the supply house that sold this unit has been shown the picture!

 

This bottom one was found in a back alley downtown. Note the undersized suction line brazed into the larger service valve. Also the bare romex running into the unit with no disconnect.
