I have a real Trane coil identified as COL18632 RPS that is supposed to be epoxy coated and not be subject to DSS. Does this code indicate any special coating? How else can I tell if Trane has sent a treated coil under their DSS coil replacement program.
An earlier Goodman setup (2 ton HP, Var Speed fan) never got DSS.
Not to be a skeptic ... but DSS triggered a heck of an allergic reaction a few weeks ago. A germicidal bath solved the problem, but I can't afford having it come back.
