Micronta 22-123 Power Supply circuit diagram error

There is an error in the circuit diagram that is in the manual for Micronta 22-123 variable power supply, which is available at this web site.
The potentiometer that the user adjusts to obtain the desired output voltage is labeled R12. The error is in the labels to the left and the right of the sliding contact. Turning the voltage adjust knob clockwise moves the sliding contact to the RIGHT (not left). The MIN and MAX labels should be swapped, left for right.
