I will pick this up in a couple of days. When I get a chance to look at it I will sort a position out for the outside unit. I may get some brackets and fix it higher up on the wall to minimise ingress of dust.

I am still undecided as to it serving the lounge or bedroom.

I am a lot happier with the flared connection too.

I have been reminded by SWMBO that I have a number of jobs to complete before I start this one.

The spec does not give the length of the interconnecting cable, but I assume it can be extended.

Once mounted and wired I will be looking for an engineer to Vac down and check final gas pressure.
