THETFORD ELECTRIC VENTILATOR - Detailed installation and review of this toilet extractor fan kit.

I wanted to reduce any smells from the van toilet so decided to install the electric ventilator kit for C260 Cassette Toilets from Thetford. The kit comprises of new control boards, a fan and a charcoal filter which actually draw air from the bathroom down through the toilet and out of the van. With the air going in the opposite direction vapour from the cassette can't enter the van.
Installation is fairly simple but involves several steps so in this video I've tried to show every single step in as much detail as possible. Please be aware that the steps will differ slightly from model to model but overall they are very much the same in principal.

Ventilator kit purchased from Prima Leisure (other suppliers are available, link is not affiliated.)

Mate, this is the best explanation I have seen on the cassette vent tube, I couldn't figure that out, THANK YOU
Mine is a C400 and the SOG is to be fitted below the cassette, I couldn't figure how that could pull internal air from the cassette.
Your a legend and answered my puzzle.
Best wishes

I have recently changed from a caravan which already had a SOG ventilator to a motorhome and would like to fit a ventilator. I found this video useful as it clarified how and when the Thetford fan operates. The SOG seems much more practical as it is linked to the cassette blade so that the fan operates whenever the blade is opened, thus preventing any odours escaping into the habitation area. With the Thetford fan it appears that you have to start the fan manually, using the flush button.

Great walkthrough, Thanks for uploading this.

Hello & thanks for the video, I've had a Valencia in the past with a SOG unit pre-fitted. I valued it but it was fiddly & seemed a little under engineered. I am getting a 2018 Cartagena; might that be the same model as yours? I am wondering about the drilling section & hitting that plate you found - thus - may follow your example & not go with the supplied 85mm vent & perhaps drill the (36mm I think you said) smaller hole instead. That said; would you be able to explain how you made the replacement that you used or what it's composed of please? Thanks in advance :)

Hi, very informative video. I’m planning on installing the same system next week on our van. Couple of questions, what did you make your flange with to fill the larger size hole in the floor? Also, I’m struggling to find a 36mm hole saw without spending about £30. Did you use a hole saw or a spade drill usually used for wood? Many Thanks from John 👍

Did you get an answer from Thetford regarding LED level indicator?

I had a SOG on one motorhome and it was horrible. Not only is the vent pipe dangling around in the cassette chamber but you have to disconnect the vent pipe from the cassette in order to remove and empty the cassette. This process reveals a hole directly into the cassette and when you lift it out to carry it away, the cassette contents can slosh about and come out of the hole. No thanks. I have also had the Thetford vent system and it works perfectly: no smells and with no interference to the normal emptying procedure.

hi when you conected the power to the toilet in you video, @ mins 10.24 .. was the live feed purple or white..

[famdrijver]

I just dilled a 40 mm hole and put in a 40 mm fan, I added a micro switch to the blade, so the fan turns on as soon as you open the toilet, and that's it. Might add an activated carbon filter in the future.

Have you still got the original floor vent..

Don’t want to knock the effort you’ve gone to, but this was not a detailed video, this was the equivalent of teaching your 17 yr old to drive by saying jump in, start her up and drive down the road, if you are trying to show some one how to do something you need to assume they know nothing ie me.
