Hi Guys, I have chosen a Daikin system 4 inverter. The Air-con man says the compressor is slightly too big to go through the MBR's window to the air-con ledge. He has suggested to cut off the frame of the window at the bottom by 3cm to let it through. And of cos he will 'repair' the cut after that. How is the frame/window built smaller than others? Regards. Dave
