Hello, i hope this is the correct spot to post this...

I just purchased a home (Trane system “heat pump” installed Sept 2009) and I have a cleaneffects air cleaner installed on the Trane air handler. The plug is not inserted into the cleaneffects door and when I plug it in it will not turn on. So I took the service panel off the air handler and the red wire for the cleaneffects is not connected to the low voltage panel - obviously why the cleaneffects won't power on. My question is should I connect the red wire to the red terminal and try it? The filters are clean as a whistle and look like they have never been turned on. I think I would like the air cleaner but want to check before I turn it on as someone before me unhooked it for what ever reason... Risks? Thanks!
