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.
