Chausson Welcome 75 / Truma C6002 EH

Hi All

I’ve come to ‘drain’ down or at least practice doing so with the recent cold snap catching me out anyway (first winterisation for me)….and have noticed the clip in the photo on the drain down/electrical safety valve….

I’m thinking it’s dumped for the previous owner and they’ve added this to prevent it doing so.

Is this normal or a sign of a damaged safety valve?

Also do people generally empty the Truma heater water from the heater itself or just the clean water tanks?

Any advice appreciated

Yes it does look like the clip is too stop the valve opening.
When in the up position the valve is closed allowing water and heater operation.
At about 3 or 4° it opens , draining the heater.
If the van is in use the heating from the boiler stops it dumping , hence all is ok.
If the van is cold the valve is designed not to lock in the up position.
The valve can be gently pushed open or closed manually.
Note this older valve ( I have one on mine) requires an electric connection to your hab battery to work.
If you don't have that it won't lock in the closed position. Might be worth checking.
It consumed about 50mA as far as I remember.

Nice one…yeh I remember when we got it I’d noticed the clip but tbh we got caught out with the cold weather before I’d investigated draining anything for winter.

I’m just hoping nothings been damaged.

I’m also confused about whether there is water in the boiler or not? Would it not turn on if it was empty (or put another way can you damage the boiler by running it dry?). I’ve checked the book but it’s not telling me much about that.

Right I’ve traced the electrical connection back…it’s NOT connected….thus why they used the clip I guess, they just used it manually and not as a safety device.

I have a chausson 70, on mine the power feed for the valve is connected to the same fuse as the spark igniter on the fridge.

I was removing the fridge to do some maintenance, and somehow I managed to short the igniter feed blowing the fuse.
So there I am in the van holding the fridge half way across the corridor, and suddenly confronted by the sound of water pouring out from under the van, and the pump going like the clappers. I hadn't had the van long and didn't even know that the emergency valve on the water heater existed.

No problem running it dry.

If the boiler is the same as mine, there should be no problem with running the boiler, i have used the heating without any water in the boiler,
