Adding 2nd ac

[Ksanch]

I'm adding a 2nd ac to my tracer 3200 bht 50 amp service. What is the best way to remove sealed from the vent to be removed?

I used a small amount of heat(heat gun) and a plastic putty knife to gently remove what caulking I could. My new AC sealed great, even with a minor amount of old caulking left on the surface

Thanks I will give it a try next week

Do I need to put any sealant under the ac and the roof

[jtstromsburg]

No, just the foam piece, as far as I know. I watched a couple YouTube videos, and did like you are, following others experience. It was easy, other than getting the Unit onto the roof. Bobcat skid steer helped that.

Thanks I put it on this evening wasn't to bad just had to help putting it on the roof. Didn't have a skid steer dut could reach the roof from the back of my truck
