GENERAL SAFETY INSTRUCTIONS
The following rules should always be observed:
1. Keep the work area clean. If the work area is busy or the surface is untidy the probability of injuries is higher.
2. Do not use the machine in dangerous environment conditions. In order to prevent electric shock, do not
expose the machine to rain and do not use it in a damp area. Keep the work area illuminated. Do not use
the machine near gas or flammable substances.
3. Keep unknown persons and children away from the machine. All unknown persons and children must keep
a safe distance from the work area.
4. Protect yourself from electric shock. Ensure proper grounding and do not touch any live connectors.
5. Handle the power supply cable with care. Do not pull the electric cable to disconnect the plug from the
socket. Keep the electric cable away from heat, oil and sharp edges.
6. Always use personal protection devices: Wear protective goggles. Wear ear muffs or plugs in noisy areas.
Wear gloves when handling parts with sharp edges or the conditioning solution.
7. Disconnect the machine from electricity if you do not use it, before maintenance and change of accessories.
8. Use the machine, the tools and accessories in the way and for the purposes mentioned in this manual.
Different uses and parts may cause risks for the operator.
9. The machine must be repaired only by qualified people using original spare parts, otherwise risks may arise
for the operator.
10. Never store the unit at temperatures below 2 °C with liquid inside the internal pipeline. This will cause
irreversible damage to the electrolytic cells.
11. Only use demineralized water according to the specification stated in this manual.
12. Only operate the unit in a room with sufficient ventilation.

HAZARDS DESCRIPTION
The owner/operator and the user of a device operated with hydrogen needs to be aware of the potential dangers
and know what to do in case of an accident or emergency. It must be ensured that the system is installed and
operated in compliance with local regulations and standards.
HYDROGEN HAZARDS
Hydrogen itself is not a hazardous substance –its properties, however, can make it hazardous in interaction with
other substances.
It is the user’s responsibility to implement a proper safety area (see specifications on par. “Safety Area”).
✓Danger of death due to explosion!
✓Escaping hydrogen can ignite and burn the skin.
✓Escaping hydrogen can reduce the oxygen concentration and cause respiratory difficulties.
✓Do not inhale hydrogen.
✓The lab/room must be equipped with a suitable ventilation system for the use of hydrogen.
✓Incorporate the unit, especially the vent line, into the operational safety concept.
✓The lab/room must be equipped for hydrogen monitoring.
✓Avoid heat in the vicinity of the system and the hydrogen source.
✓No smoking, no naked flames.
✓Comply with local safety regulations.
✓Comply with regulations for handling of compressed hydrogen cylinders.
✓In the case of escaping gas, keep away and keep inflammable materials away.
✓Prevent electrostatic charges.
✓Ensure proper installation of the hydrogen supply.
✓Check the hydrogen lines and connectors regularly for leak tightness.

MECHANICAL HAZARDS
As for the generic mechanical hazard that can occur during operations requiring the use of hand tools, Enapter Srl
recommends wearing appropriate Personal Protective Equipment (PPE) and to use suitable tools.
Operator’s protection
When performing any operation, the operators must wear the appropriate PPE, such as cut
resistant gloves, safety shoes, protective goggles etc.
The preliminary steps of the installation phase do not necessarily need to be performed by specifically trained
personnel. A general training on how to transport heavy and bulky objects, the use of electrical equipment and the
application of general safety principles is sufficient.
There are residual risks associated with the manual handling of the packaging and of the device during installation
that can result in:
✓impacts due to uncontrolled movements of the load,
✓entanglements,
✓falling of the load,
✓loss of stability,
✓overturning.
To prevent these risks, the packaging/device must be handled by at least two people.
Operators must comply with the general safety principles during the handling phases.
In particular, before moving a load:
✓Operators must allow for sufficient clearance when using aisles and passageways with
openings/doorways with at least 500 mm of free space in width and height, to grant the easy
transit of the packaging and/or machine parts.
✓Operators must verify that there are no people on the passageways.
✓Operators must verify that there is sufficient visibility to grant a safe moving of materials.
