INSTALLATION
When choosing a location for the installation of the EL2.0, pay attention to the following:
•
The unit is designed for use in indoor settings.
•
Do not place the device into a sealed or unventilated space/room.
•
Direct contact with flammable gases is to be avoided
•
Do not place flammable materials in proximity of the device.
•
Do not place the unit over or near a source of heat, as this may cause the device to overheat.
•
Do not use naked flames/do not smoke.
•
Avoid any risk of the building up of an explosive concentration of hydrogen.
•
Do not place electric equipment near the device so it cannot get wet by the water from the hydrogen relief port.
The unit should be placed on a flat, level, vibration-free, shock-free surface. The electrolyser should stand free,
without touching any objects in the vicinity. In front of the air inlets of the fans there should be a free space of at
least 30 cm.
The ambient temperature must be between 5 °C and 45 °C and should be preferably stable.
Installation in outdoor settings is possible as long as the electrolyser is shielded from direct contact with atmospheric
influences, such as sunlight, rain or snow. The EL2.0 has no appropriate electrical protection for exposure to dust
and water, it must be protected accordingly against this risk.
For special installations in very humid, wet or partially open environments, please contact the producer to ensure
the correct use and installation of the device.
SAFETY AREA
The operator of the EL2.0 must define a safety area which must be free of any source of ignition. This area should
be located at a height of 3 metres above ground or higher.
The lines from the ports H1.1, hydrogen output, H1.2, hydrogen purge and W1.1, O2 vent/overfilling must be led
into the safety area.
H1.2:
At the end of operation or after 24 hours of continuous operation, whichever comes first, the electrolyser
depressurizes, releasing a total of 19 litres of hydrogen within two seconds, equalling a momentary volume flow of
34 m³/h of hydrogen. The hydrogen is released via the purge outlet
port labelled H1.2. The released hydrogen bears
the risk of explosion
–
therefore, it must be piped into a safe area.
The size of this zone depends on different parameters (length/diameter of piping leading to the safe area, use/no
use of an orifice plate, use/no use of a blowout pipe at the end, etc.).
Generally, there are two options:
WARNING!
Inappropriate installation of the EL2.0 or installation differing from that described herein shall lead to
the loss of warranty coverage and shall release the manufacturer from any and all liability set forth in
existing legislation.
