I am curious to find out if anyone else has come across this issue. I have been doing HVAC work *both commercial and residential* for about 9 yrs now and have never come across the problem i did today. After installing two 5 ton rooftop units and getting the inspector to approve it, he came back saying that he could not pass it unless i had a float switch on both units. I have never had to install a float switch on a package unit before and i thought this was a little crazy. The job was in Ky, so i'm not sure if anyone in other states has any information on this or if this inspector was just being ridiculous. I do not know of any code that requires a rooftop package unit to have a float switch installed.
