Desperately looking for instructions

[jenny]

I have bought a burstner lux caravan, but have no instructions on how to use the indoor toilet and shower. I would especially like the instructions for the shower and what connections are required.
The chassis number is:-
VGF5205TSL1101147
I think it was manufactured 12-15 years ago.
I have been in touch with Burstner in Germany, but they cannot help me, and the caravan is in France.

I would appeciate hearing from anyone who has the same or similar caravan.

Thanks
