What to do if Zero Air Generators indicate “overflow” fault?
• Check to make sure that actual flow of zero air needed is within the rated output capacity of generator. • Snoop all tubing connection points from the outlet of the generator to the inlet of each instrument. A tiny leak is enough to cause overflow fault. • Install properly sized WFM series flow meter off the outlet of the generator. • Open right side-panel door and look / listen for air leak. • Call Parker technical services at 800-343-4048.
