Centurion3000: model#cs6000

Hello all at ExplorOz,
I am once again writing to ask for help, the members gave us great input when we asked for advice on what pop top caravan to buy Jayco/Coramal, this time we are seeking advise on the above converter.
The family we purchased the van from had very little in regards to manuals and knew nothing about the caravan as they where selling on behalf of the parents, great help as it is our first pop top van: I gather the converter converts 240v to 12v lighting when we hook up to the 240v mains. What I would be obilged in getting is a manual, I have tried getting one on to the makers website but iit s no longer available.
As the van does not have any battery system/pack installed I was hoping to set it up my self if its not to difficult: I'm fairly handy with a nail gun. What I asking can any one supply me with a copy ( I am happy to pay any costs involved) or where I can obtain one or any other advice etc.

As in previous asking for helpL: thanks for anticipated assistance.
