Not familair with this one specifically. I did have a 19" wide capable three tank Kreonite roller processor for a while.

I could lift the body myself only if I took the lid off and moved the three roller racks separatly first.

Wear old clothes - usually old processors have all sorts of puddles of blix etc spilled in the bootom that has turned to crud over time.

Be prepared for a lot of cleaning . If it comes clean, lucky you. My Kreonite had a filthy first tank (developer) fabric coated roller that came clean only with a full dissassembly and multiple soaks and scrubs.

You and lots of dilute toilet bowl cleaner are likely going to get to know each other more in the coming weeks than you have ever thought of the stuff in your whole life.
