Serial numbers on Jandy products provide information about the product's model, age and warranty status. To read a serial number:
• Locate the tag containing the serial number. This can be found on either side of the heater or filter equipment, depending on manufacturer models.
• Read each group of characters from left to right; they are separated by dashes and spaces.
• The first group is typically two letters followed by four numerals; these refer to the model type and year built respectively.
• The second set indicates month/year shipped, while the third provides an indication of week shipped in that month/year period.
• Finally, there may be a few more digits related to specific parts used for that particular unit - ignore these as it won't affect your reading of the serial number overall!
