Harry Bissell Morph-Lag: Capacitor C1 question

[creekree]

Hello,

I am looking at this schematic and I cant figure out what C1 is supposed to be... electrolytic? Where does the positive terminal go? The symbol used in the schematic is non-polar, however, there is a picture of the Livewire version of the module here, which clearly uses polarized electrolytics. Also the schematic says 5uF, which I have never seen before, so I´ll go with 4.7uF instead.
It would be nice if someone could help me a little with this.
Thanks!

Christian
