Author Posts 18 Apr 2013 at 12:52 pm #280120 Sleeper Hello all,My question is quite simple, is it posible to find instructions to set up and use my Junkers W250K1 HWS (circa 1983)? More particularly what does the control lever on the front of the unit do?What does the Round knob with a red triangle/white triangler, do? Thanks if you can helpSim 4 May 2013 at 12:44 am #302338 rogdav I was looking online for a manual for you but I am struggling to find one. I will post you a link if I find one.
