2.2 General safety instructions
Read the user manual before commissioning the fuel cell, and keep the
user manual close to the device at all times.
Follow all of the instructions in this user manual.
For Indoor use only. Use the EFOY Pro fuel cell only in housings with
protection against water and dust.
The EFOY Pro fuel cell must not be opened.
The EFOY fuel cartridge must not be opened or refilled using excessive
force.
Modifications to the device constitute a safety hazard and may result in
the loss of your operating license and nullify your warranty and
guarantee.
Use original EFOY accessories only.
EFOY Pro fuel cells and EFOY fuel cartridges must not be stored and
operated at temperatures over +50 °C / +122 °F.
Protect from heat and direct sunlight.
Operate the EFOY Pro fuel cell only as specified in the installation
instructions, and in a well-ventilated space.
Keep EFOY Pro fuel cells that have been switched off in frost-free storage
or use the automatic antifreeze feature.
Do not smoke in the vicinity of the EFOY Pro fuel cell or EFOY fuel
cartridge. Protect from heat and ignition sources. Methanol is highly
flammable!
Keep all EFOY Pro fuel cells and EFOY fuel cartridges out of reach of
children, even when empty or only partly full.

Safety Information
Page 7
WARNING!
In exceptional cases, the exhaust gases emitted by the device may contain
substances that are harmful to health!
Do not inhale exhaust gases directly for prolonged periods. Instead, use
the exhaust tube provided to route the exhaust gas into the open air.
WARNING!
Damage in the event of an accident; risk of injury!
EFOY Pro fuel cells and EFOY fuel cartridges must be securely fastened
to prevent damage in the event of an accident.
WARNING!
EFOY Pro fuel cells must not be used in potentially explosive
atmospheres.
CAUTION!
Burn Hazard.
Hot surfaces. In operation temperature up to +65 °C / +150 °F at heat
exchanger possible. Do not touch.
CAUTION!
The EFOY Pro fuel cell is not water-tight!
Ensure that no water can enter the fuel cell.
CAUTION!

2.3 Safety instructions for methanol
INFO:
There is no risk of you coming into contact with methanol provided that
you handle the device and fuel cartridges in accordance with the
instructions.
DANGER!
Leakage of methanol fumes poses a fire hazard! Do not smoke when
replacing the EFOY fuel cartridge and do not expose it to other ignition
sources! Protect EFOY fuel cartridges from temperatures exceeding
+50 °C / +122 °F.
Leakage of a small quantity of methanol will evaporate, leaving no
residue. Do not touch leaked methanol.
WARNING!
Methanol is highly flammable!
You receive methanol in safe, tested EFOY fuel cartridges, which prevent
the contents from escaping if used correctly.
The storage and transport of methanol may be subject to statutory
regulations.
For more information, refer to the safety data sheet on methanol,
available on our website at http://www.efoy-pro.com.
WARNING!
Methanol is toxic when inhaled, swallowed or allowed to come into
contact with the skin. Inhaling and swallowing methanol, or allowing it to
come into contact with your skin carries a serious risk of irreversible
damage.
Call a doctor immediately if you have direct physical contact with the
substance, in the event of an accident, or if you feel unwell, and show the
doctor the fuel cartridge label or the methanol safety data sheet.

Safety Information
Page 9
CAUTION!
Impurities in methanol!
Original EFOY fuel cartridges contain methanol that has been approved by
SFC. Even slight impurities or foreign particles in commercially available
methanol may cause irreversible damage to the device, and may nullify
the warranty or guarantee.
Use only original EFOY fuel cartridges!
