G'day, | Folks, I guess I just started removing the KAF2 for filter aligment when I | first had to deal with it Unnecessary 'cos there is a slide switch on the KAF2 just for that purpose, to bypass it. If the KPA100 lid is fitted, the switch can be conveniently used just by removing the top panel just in front of the heatsink. Regards, Mike VP8NO #1400
