Baz this is looking a different unit from when it left mine a week or 2 ago. Baz Paul said about using some R410a and see how the unit handles it. I'm sure paul will give it a go once its setup and he is familiar with it. You want to use it for anythink mate let me or Paul know and ill drop it down.
Also Baz me and paul use Spray glue to seal the Neroprene back together once placed over the pipes. I get this from work
ill put you by a few tins if you like
Again nice work.
