Opening a Axeon Hf5 4040 Membrane housing?

[Neilmnwc]

Hi all,

I've ran into some problems opening up my Hf5 4040 membrane housing. I've never opened it before and can't open it. I don't want to resort to brute strength and damage it so was wondering if anyone can offer a glimmer of hope please.
I've attached photos so you can see the unit.

Not seen one exactly the same as that but think you need to take the screw out of the yellow bit then carefully remove the white ring by prising it towards the centre of the housing and working around the ring with a couple of screwdrivers they come out quite easily

You have a Champ housing. Remove the yellow wedge by unscrewing it. This will leave a gap in the white locking ring. Remove the white locking ring by levering the locking ring ends together. It is just a large circlip.

You may have to screw a radiator valve into the centre port to remove it.

Cheers @spruce, very helpful as ever?
