I wondered if anyone had any dealings with the Mitsubishi Electric replace technology.

I'm interested in replacing an older system where pipework is restricted, and the Mitsi replace option would be ideal.

Trouble is having spoken to Mitsi, I'm led to believe that my existing systems liquid line being 1/4" is too small and thus Mitsi apply correction factors that limit my indoor/outdoor seperation to 10m.....no good!

Are any other manufacturers offering similar technology, and has anyone her worked with this replacement technology before.........
if so I would be interested in your comments?

Apparantely up to 10kw you plug and play, anything above you switch a dip switch that bypases the refrigerent through a filtering stage for 2 hrs before switching back over again. Amazing stuff!

Many thanks.
