Hello. Evaporator replacement

Hi, new to this XK section and about to embark on the replacement of the Evaporator on my 2007 XK convertable. The car has done 25k so far and has been hassle free. I have fitted the remote soft top from Wrangler which has proved to be really good and allows you to operate the roof and window from the remote key. It also allows you to bring the quarter light windows up when the roof is down.

So has anybody replaced the evaporator so far and are there any issues to watch out for.
