How do I determine the age of an AquaCal pool/spa heat pump from the serial number?
Wednesday, June 13, 2018
Older data plates are stamped metal and newer ones are a printed sticker, but they use the same serial number format. Look for the dash at the end of the first series of letter/number digits. It will be followed by a single letter and two numbers. The two numbers are the year of manufacture, and the letter is the month in an A = January, B = February, and so forth, format.
Here’s an older stamped metal one above. It’s hard to read from the photo, but the serial number is CPA B33225 - C98. So it was manufactured in March of 1998. And the newer one below is January 2014.
And here’s a more recent one with “I17,” which would be September of 2017. You have to look carefully to tell that it’s an “I” and not a “1."
