The manual date is a revision date and not a printing date, if it has a controller it was made after June 2015 (no controller before then). The magnets and power supplies transitioned around the same time. Since the new pumps include a controller, the jumpers are not needed so they have been discontinued. 6055 and 6095 used 6055.240 (jumper power supply should be set to 24V with 7090) or 6095.240 (no jumper for use with 7090 controller). I suspect the one pump is from June/July production, the other is from later this year.
