Holding tank on a Oceanis 36CC

Hi
I know cliffb referred to his installation in the old forum.  I have just purchased a 36CC which previously had a holding tank installed in the cupboard in the heads. But it was uninstalled by a previous owner. I have the tank and supporting yvalve and pipework and intend to refit it. But it is not clear exactly how it was installed.
I wonder if any 36CC owner that has the tank still installed can send me photos showing how and where in the locker the tank is supported/fixed and where the various pipes and valve are routed / fixed. Alternatively,  a schematic showing the same.  I'd also appreciate any comments or notes about the use of the tank.
Thanks in anticipation.
