I've been using a recirculating pump and line cleaner. There's one account that has Micro-Matic FOB's installed. I know what they do, but not how they work. I don't know how to do the cleaning of the lines with these in place. There are nine line in all and there appears to be "blow-off" tubes that void into midair above the kegs.

Can someone advise?

Thanks in advance.
