I would like to know how to read the labels for the manufacturing date.
IS there a guild book we can find.
Please help.
Thanks

No quick book guide. HVAC personnel know how to read them because they deal with it every day. Usually every brand has a different way of disclosing the date. Year month and day of manufacturer.

Thanks
But I know in fact whereI can get one,
I am only trying to see if there is other source, beside what I already know.
Thanks again away
