Victron IP65 Blue Smart Charger 12/25 230V AU/New Zealand Installation Orientation

Hello All,

I know the manual states to mount this charger vertically however this cannot be achieved with the room I have to mount permanently in a Sprinter Camper-van. I can mount this horizontally with a wall mount with adequate space around it for ventilation or I could mount it flat on the floor. My question is which would be the best solution in my case floor mounted or horizontally mounted and will it effect the ventilation of the unit greatly or the warranty regards Dave.
