Installation
Receiving the generator
All units have been carefully inspected before transport. Visual checks for damage and func-
tional tests should be performed upon receipt. Any damage has to be immediately noted and
reported to the shipping agent and supplier. The generator has to be returned according to
the shipping instructions provided.
Placing the generator
The hydrogen generator should be placed on a flat, level, vibration-free, shock-free surface.
Do not place the generator over or near a source of heat, as this may cause the device to
overheat. The unit should not be in contact with any other objects on any side, and the air
inlet must not be blocked. Leave at least 30 cm of free space at the rear for ventilation.
Do not operate the generator in a sealed or unventilated room, or in close proximity to open
flame or other sources of ignition. The ambient temperature (preferable stable) has to be be-
tween 15°C. (59°F) and 40°C (104°F).
WARNING!
Compared to cylinders, the gas volume of the generator is very small.
However precautions for any hydrogen supply should be taken when using the generator.
DO NOT use the generator in sealed or unventilated rooms, neither use it in close
proximity of open flames or other sources of ignition.
Gas connections
Pure dry hydrogen at regulated pressure is available at the hydrogen outlet port at the rear
of the generator. This port must be connected to 1/8" SS or copper tubing using the appro-
priate Swagelock fittings. Teflon tubing is not suitable. The pressure at this port is adjusted
via the keyboard and shown on the display. The hydrogen relief port at the rear of the unit
can be connected to an exhaust hood or other vent system.
WARNING!
The line from the relief port (over pressure) should never be connected in such a way that
back pressure can develop.
