1. Screw the hydrogen hose firmly to its counterpart on the screw connection (1);
make sure that there are no leaks
IMPORTANT!
The screwed connections (1) for the hydrogen vent lines have a diameter
of 1/4 in. NPT with internal thread. The ventilation lines must have a mating counterpart
and meet the following requirements:
-
Fire and corrosion resistant (e.g. stainless steel)
-
There must be no leaks from the screwed joint with the counterpart
-
Pressure loss from the line: max. 5 mbar (0.0725 psi.)
-
Pressure: PN 13.6 (bar), (197.18 psi.)
-
Volumetric flow: max. 10 Nm³/h (357.14 cfh)
-
Length: max. 10 m (32 ft. 9.7 in.)
-
Diameter: DN15, (0.59 in.)

IMPORTANT!
The screwed connection (1) for the hydrogen supply has a diameter of 1/
4 in. NPT with internal thread. The ventilation line must have a mating counterpart and
meet the following requirements:
-
There must be no leaks from the screwed joint with the counterpart
-
Hydrogen supply pressure 5 to 13.6 bar (72.49 - 197.18 psi.)
-
Hydrogen volumetric flow 1.7 Nm³/h (60.71 cfh) - energy cell 25F
-
Hydrogen volumetric flow 3.3 Nm³/h (117.86 cfh) - energy cell 50F

WARNING!
Incorrectly routed hydrogen ventilation lines increase the risk of
fire, explosion and suffocation. During and after assembly, the hydrogen
ventilation lines must meet the following requirements:
-
Observe the relevant national regulations when configuring the hydrogen
ventilation lines
-
The hydrogen ventilation lines must be routed into the open air
-
There must be no sources of ignition or fire loads in an area 3 m around
the outlet (cone) of the hydrogen ventilation lines
-
Ensure that the hydrogen ventilation lines are unobstructed and facilitate
the unhindered flow of gas
-
The pressure at the outlets of the hydrogen ventilation lines must be
equal to the ambient pressure (approx. 1 bar abs. - 14.5 psi.)
