[ 2 ] Recovered process unit mechanism
The process unit of this equipment has two types; one is for the 20ppm/25ppm/30ppm and another is
for the 35ppm/45ppm/50ppm.
The differences between two are shown below.
Be sure not to install the process unit to a wrong model when replacing them because they are
incompatible each other.
To distinguish them, check the position of the bracket hole seen from the back side.
