mitsi r22 to 410a system

[rbartlett]

does mitsi still do those units which you can re-use the old 22 pipework and run it on 'clean' for a few hours before switching it to 410a?

we have a customer with a tricky piperun and a dead mastair either end

cheers

correct, the Mr slims have a "replacement mode" to start it, sw8 1 and 2 on the outdoor board should be switched ON if i remember rightly it runs for 2 hours and will automatically return to normal

I believe that it only applies to the inverter models.

It only applies to the 'power inverter' range, as there is also a 'standard inverter' range now :)
