Greg,
That was my feeling also. If you have a piece of equipment outside that needs servicing, then a receptacle within 25' should be required. After all it is there for the HVAC guys when they need to evacuate the system to re-charge it. Also like you said, if it is just a tower, and the water just falls and cools, then I do not see a need for the recptacle. I was just wondering if I read that correctly.
