Age of a 6080?

[jpc763]

How can you tell how old your Tunze is?

I have a 6080 and I want to know how old it is.

I bought it used.

Thanks, John

There is a 3 digit code stamped on the pump but I do not recall how to read it off the top of my head. But if you post it roger could tell you on Monday

There are three digits pressed into the plastic, between the swivel arm mount and the label. The digits decode as series, quarter, year, so 125 for example is 1st quarter, 2nd series, 2005. A series usually spans 1-2 weeks of production, since the factory is closed until the 2nd week of january, the pump in the example would have been made in Mid February 2005.
