Hi folks, doing up a van to live in temporarily, I bought a Waeco cr1140 f/f. And as a noob hoping someone may have an answer, as the manual didn't specify. :/
Question is: Do I need to switch off 12v when connecting 240v....can I leave them both on or do i need to use a switch between them both ?

Also is it fine to leave it permanently connected to 12v if battery supply is not an issue , or run 12v batterys through an inverter to produce 240v ?

Any help would be appreciated immensely

Even though the manual says you can leave both plugs connected it is a good ides to disconnect 12 volt when connecting 240. It does happen sometimes that problems occur when both power sources are connected, particularly if over a long time. Applies to all fridges not hard to do to make sure there are no problems.
What other people think of me is none of my business.

Tony, don't run from battery to invertor, you will use an awful lot of battery power for very little, 12 volt or 240 volt where available.

You can leave it connected to 12 volt as the unit will switch to 240Volts when connected and it will work fine on 12 volts if charging is not a problem.

I would leave the 240v disconnected and run it off 12v. You would constantly charge the 12v batrtery through a 240 v charger so battery drain isn't a problem.

That way you always know the 12v side of your system is working ok and ready to go if, or when you leave 240v areas.

Inverters are a last port of call solution. Don't use those in this situation.
