Liebert Serial Number Breakdown
The first digit of the serial number is the last digit of the year for Mitsubishi. So “6” could be “2006” or “2016,” and you would need to look at the condition of the unit, and/or the date of the ANSI code at the upper part of the data plate, to determine which one. Here’s a recent example from an air handler manufactured in 2007.
And the data plate from the condenser unit for the same system, which was manufactured in 2008.
And this is another example of a system manufactured in 2020. Although it also has a single letter in the serial, you use the same first digit system for age. We knew that was 2020, and not 2010, because it was at a new house. But the ANSI Code date was 1995—so that was not much help in sorting it out.
