A multiple conductor cable connects the Source Cup Assembly to the Power Supply
Module providing current paths for the cooler and heater. The green checked
pushbutton located on the keypad illuminates the back light to view the liquid level
through the window on the Source Cup Assembly. The bubbler containing the chemical

allows for easy access, installation, maintenance, and replacement of the bubblers.
