Im a store owner and I have a 5 ton HEIL rooftop unit. The condensate drain pan is cracked where the pvc fitting goes into pan. Water is dripping into my store. I want to replace pan myself. What are some of the basic step's I need to take to replace entire pan. Is there a tech. number I can call or website with the step's I need to do. Thanks for any help in the right direction.

You might have to remove coil to replace pan, and in order to do that you need to have a license to handle refridgerant.
Might be able to replace with out removing coil, but you have to be extra careful and not damage anything.
My advice call a tech to comeout. It might cost you more, but it might save you a lot in the end.

Ive used a good 100% silicone make sure its good and dry apply real good over and around the cracked parts,let set up for a few hours,, should last you for while,
One I did outlasted the rooftop unit
