Mitsubishi Split Component Compatibility
I have an older MXZ-4b36na outdoor unit which I have both an available zone connection, and capacity to allow an additional indoor unit. Recently, Mitsubishi came out with a new narrow design ceiling cassette (MLZ-KP series) which fits a standard joust spacing. I would like to install one of them. According to their compatibility charts, my older MXZ-4B outdoor unit is not listed. I also get conflicting advice from local contractors, and of course the distributor won't talk to me. (Haven't yet contacted Mitsubishi directly) So, from your expertise, will this new design cassette cooperate with my older outdoor unit? Thank you in advance. Brian
