Note – Item 3 (PD sensor valve) is for diagnostics only. When closed the dew point reading is taken from line. By
opening this valve, you can read the dewpoint between the dryer column and QDT filter. This allow you to determine if
a dew point fault is due to the dryer column not performing or the QDT has become saturated.
