Split type wall mounting Air Conditioning system

[stevews]

This particular system came with pre-flared 5m x 10mm pipes and 5m x 6mm pipes.

Having installed the indoor unit carefully without kinking the copper pipes, I wasn’t so lucky when I connected the last 10mm pipe to the outside unit. I gave the pipe such a bad kink I don’t think the gas will get trough properly.

My question is two fold.

A) Can I simple purchase another fully prepared i.e. pre-flared 10mm pipe, 5m in length?

b) Purchase a few couplings to make the job easier in the first place and avoid another mistake of kinking a pipe when trying to bend it?

All I can establish about purchasing copper pipe is the thickness of it and how that tends to tends to be relevant to the preinstalled frigerant gas - my system uses R407c.

Can anyone recommend a supplier in the UK that could supply either of the two options above? a link would be great.

I would extremely grateful for any advice as I feel such an idiot about ruining the whole installation because of 1 stupid mistake.

Look forward to hearing from you guys soon.
