Fitting your own air con unit?

[plugsandsparks]

Dont want to appear pedantic, but Fgas regs (which are statutory) dont allow using Fgases to push air, residual N2 and moisture out of the system. OK R290 is basically propane, but it is a small charge so using some of it to purge does appear a bit odd. Anyway this is getting like a DIY thread for electricians, Fgases are dangerous, you need to be competent and legally qualified to work on Fgases. Ha ha never thought i would be saying that, lol
Good Luck, BTW, please use a glove when purging with Fgas as it can really hurt

How risky is it for a retired spark fitting one of those mini-split units in my own place ?

Don't fancy doing anything dodgy with gas

I fitted one of those exact units along with a pal as he needed it for his office.
It was a simple, straight-forward task as it was pre-charged and the pipework was pre-assembled. The trick is to order the length of pipework to suit, better too long, and then position the outdoor unit accordingly. It was a day's work, and works extremely well. Also, the supplier was very helpful on the phone when we had a couple of queries.
The hardest part was drilling the outside wall, and that's not exactly difficult. The quality of the kit is impressive.

I went out to a couple of the diy style AC units back in the day. One I remember the PCB was showing a fault code, the technical team had no idea what they meant and replaced the whole condensing unit. Others had leaks on the premade flared joints.

The old boys used to just purge a bit of gas through.

That was before they updated the safe gas handling course unfortunately. I think I could make a fair bit fixing heat pumps if I had the updated quals. @plugsandsparks how long was the f gas course?
