Clarification of M 307.2.3

[bigdog]

M 307.2.3 is confusing to me.

I can't figure out whether or not an emergency pan is required under an air handler in a second or 3rd floor location. Common sense would dictate yes but the code........

It states an auxiliary method of protection is required and then lists 4 options of which 3 are pans and the 4th one goes back to a float switch in the primary drain. Where is the protection when the pan cracks or leaks?....or the coil freezes up and then melts all over the floor.

Thanks Jerry.....I fell a little better now. This goes into the same file that allows washing machines on 2nd and 3rd floors with out a pan of some kind.
