5. SERIAL NUMBER BREAKDOWNS.
A. LONE STAR
For 1986, Lone Star is using a date code which breaks down as follows:
L 5 10 02
=L51002
Letter L for Year Month Day
Lone Star
In this example, this label would indicate a unit produced on October 2, 1985 by Lone Star. (Example: 5=1985, 10=October, 02=day).
B. HITACHI
For 1986, Hitachi Kit and L.I. models are using a date code which breaks down as follows:
KIT - H = H5080001
5 08 0001
L.I.- F = F5080001
Kit or L.I. Identifier Year Month Sequential Number
In this example, a serial number with a prefix H, would indicate a kit A/C produced in August, 1985, with a sequential number of 0001. A Line Installed A/C system would be identical except the prefix would be F. (Example: F=L.I. unit, 5=1985, 08=August, 0001=sequential number).
C. MATSUSHITA
For 1986, Matsushita is using a sequential numbering system. Since Matsushita is L.I. only, all prefixes start with F. The remaining numbers are the sequential numbering numbers. (Example: F=L.I. , 00000001=Sequential Number).
Including the name of the A/C manufacturer, evaporator serial number, color, and prefix are valuable assets when reporting service problems.
