Directions for Attaching the Hydrogen Filling Station to the Hydrogen Supply Tank
1. Connect the hydrogen fuel cylinder filling station to the tank of hydrogen. Hydrogen is supplied with a
CGA 350 cylinder valve outlet. The filling station is supplied with the matching fitting for ease of
connection. The threads of the adaptor will tighten counterclockwise.
NOTE: Do not force the connection. Do not use Teflon tape with CGA fittings. In general, these fittings
are designed for metal to metal sealing.
Do not use adapters to connect one CGA fitting to another type of CGA fitting. If the refill adapter does
not match the outlet on your hydrogen tank, contact INFICON.
2. Tighten the hydrogen cylinder filling station onto the tank with a wrench. Do not over tighten.
WARNING
DO NOT Use an open flame to test for leaks!
WARNING
DO NOT fill the hydrogen cylinder in a hazardous location.
