Filling the Hydrogen Fuel Cylinder
1. Rotate the output valve to point toward the main cylinder of hydrogen (Filling Position)
Figure 9. Output Valve
2. Attach the MicroFID II hydrogen fuel cylinder to the quick connect mate on the hydrogen filling station
(see Figures 8 and 10).
3. Open the on/off valve on the hydrogen fuel cylinder. See Figure 8.
4. Open the valve on the hydrogen supply tank.
5. Allow the unit to fill for the amount of usage time required as per the above chart.
NOTE: The hydrogen fuel cylinder will become warm during the filling process and will be warm to the
touch. Once the fuel cells are full, the cylinder will begin to cool down and become room temperature.
Hydrogen cylinders that are only partly depleted of hydrogen may take less time to fill.
6. Close the valve on the main cylinder of hydrogen
7. Rotate the output valve to point away from the main cylinder of hydrogen, (Venting Position)
8. Wait approximately 5 seconds, and then rotate the output valve once again toward the main cylinder of
hydrogen. (Filling Position)
9. Disconnect the full hydrogen fuel cylinder from the quick connect on the filling station by holding the
release ring of the hydrogen fuel cylinder with one hand and holding the red release ring with the other.
Push up the hydrogen fuel cylinder release ring and the hydrogen fuel cylinder will be separated from the
hydrogen fill station. The hydrogen fuel cylinder will be cool to the touch when it is remove from the
hydrogen fill station. With time, the hydrogen fuel cylinder will become room temperature.
10. Ensure the main hydrogen supply tank valve is closed.
11. If the hydrogen cylinder will not be used immediately after the filling process is complete, close the
hydrogen cylinder by turning the on/off valve completely clockwise.
