Safety - Horizon Fitness H-12 User Manual

1. Safety

Please read all instructions carefully prior to product use and keep this manual for future
reference.
The safety guidelines included here may not cover every situation. Use common sense.
1.1 General information
For this unit to generate electrical power, a supply of hydrogen fuel is necessary. It is
important for any operator to be aware of, understand, and follow all local safety
requirements related to the handling of hydrogen and compressed gases. Ensure that
your facility conforms to all local regulatory requirements, including building codes and
recommendations.
The fuel cell system has built-in safeguards and is designed to shut down automatically
if any out-of-range operating condition occurs. Possible situations include low cell
voltage, high current, high temperature, low fuel pressure.
• Do not operate the stack on a grade of more than 65℃.
• Do not connect or disconnect power cables when the fuel cell stack is energised.
• Do not dismantle the system. Contact Horizon if you have any concerns about
operation.
1.2 Using Hydrogen
WARNING! FIRE OR EXPLOSION
Keep all sources of ignition away from hydrogen.
This unit uses hydrogen fuel. Hydrogen is a colourless, odourless and flammable
substance. It is highly combustible in the presence of oxygen and burns with a
colourless flame.
Leaking gas may be hot and pose a burn danger. Stop the flow of gas – if you are not in
danger – and use water to cool the area. If fire occurs, do not attempt to extinguish
flames, allow the fire to burn out.
Prevent overexposure to hydrogen. Hydrogen is non-toxic but can act as a simple
asphyxiant by displacing the oxygen in the air. There are no warnings before
unconsciousness results. When operating the stack in an enclosure:
• Ensure ventilation slots are clear and unobstructed at all times during operation.
• Operate within the temperatures limits stated in the manual.
• Never operate if an alarm condition exists.
Note: We highly recommend customer use a hydrogen sensor(not provided) to
detect the hydrogen leakage.
