Air Conditioning Maintenance

I am going to be doing some AC (I believe it is a DuoTherm) maintance to my TT this weekend never been done since I owned it but my question from doing a search on the internet it looks like I spray the AC Foam cleaner on the condenser and evaportor fins and then rinse with water is that correct. Also anybody that has done this themselves have any tips.

Thanks

    This Blog post should be of help.

    On our RV I can gain access to the evaporator coil by removing the return air grill and the sponge filter. I use a vacuum cleaner with a soft brush attachment to remove the dust that gets by the sponge filter. I have never found the condenser coil on the roof to be dirty or blocked.

    Be careful of the spray foam cleaner around your rubber roof. I believe it is a strong alkali that may attack your rubber / seals.

    I've only ever used water (hose) and a light brush. The coil cleans up fairly well. If you have to use the cleaner, lay a tarp or something down to direct the runoff so it doesn't contact your roof.
