Changing to Gel leisure battery

[Petros]

I have a Shauldt EBL 271 fitted to our MH, I can see where you can change the charger setting to Gel but cannot see how to do it. I thought there would be a more visual switch to do it

If you move the red water pipe aside it could reveal the word "gel". If so, I guess you would slide the red switch away from "plombo" towards "gel". Check your Schaust manual for confirmation.
