Is My PR SystemOne From the 50 or 60 Series?
The easiest way to tell whether you’re using a 50 or 60 series machine is by referring to your unit’s model number: SystemOne 60 Series machines include model numbers on the base of the machine that end in 60 (i.e., 560P, 660P, 760P); SystemOne 50 Series machines include model numbers on the base of the machine that end in 50 (i.e. 550P, 650P, 750P).
