Thanks folks for all the responses up to this point. I'm getting ready to start installing my IC-60/Power Center. I've read both the instructional manuals, but could someone point me to an instructional link/how to on the steps to install. I'm searching the forum currently, but if you already know where some good ones are I'd appreciate the help. Also I read a couple of posts reagarding installing some sort of cutoff valve between the filter and the ic-60. This is the first I've heard of it and am don't have/don't know where to get the part. Is it necessary? Thanks to the posters so far that helped me pick my unit, JasonLion, susa, bobodaclown.
