2Safety Information
Explanation of safety alert signal words
DANGER!
Indicates an imminently hazardous situation, which, if not avoided, poses
a high risk of death or serious physical injury.
WARNING!
Indicates a potentially hazardous situation, which, if not avoided, poses a
medium risk of death or serious physical injury.
CAUTION!
Indicates a hazardous situation, which, if not avoided, poses a slight risk
of mild or moderate physical injury or damage to property.
INFO:
Important information for the operator or user of the system.

Safety Information

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.
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 guaran-
tee.
Use original EFOY accessories only.
EFOY Pro fuel cells and EFOY fuel cartridges must not be stored at tem-
peratures over +50 °C / +122 °F and must not be operated at tempera-
tures over +50 °C / +122 °F.
Protect from heat and direct sunlight.
Operate the EFOY Pro fuel cell only as specified in the installation in-
structions, 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 car-
tridge. Protect from heat and ignition sources. Methanol is highly flam-
mable!
Keep all EFOY Pro fuel cells and EFOY fuel cartridges out of reach of chil-
dren, 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 atmos-
pheres.
CAUTION!
The EFOY Pro fuel cell is not water-tight!
Ensure that no water can enter the fuel cell.
CAUTION!
Improper use or improper connection to other electrical equipment may
lead to damage.
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 instruc-
tions.
DANGER!
Leakage of methanol fumes poses a fire hazard! Do not smoke when re-
placing 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 resi-
due. Do not touch leaked methanol.

Safety Information
Page 8
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 regu-
lations.
For more information, refer to the safety data sheet on methanol, availa-
ble on our website at http://www.efoy-pro.com.
WARNING!
Methanol is toxic when inhaled, swallowed or allowed to come into con-
tact 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 sub-
stance, 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.
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!

conform to the technical specifications of the device (see chapter 3.3
"Specifications" on page 16).
•The devices can be used according to the technical specifications for
stationary and mobile operation in vehicles (see chapter 3.3 "Specifi-
cations" on page 16).
•The devices must only be operated with original EFOY fuel cartridges.
Damaged fuel cartridges may not be used.
•The devices are not intended to be used as an emergency power sup-
ply for medical, life-sustaining or agricultural systems.
•Connecting several devices in parallel to increase the charging cur-
rent is permitted.
•Connecting several devices in series to increase the voltage is not
permitted.
•Devices with a defective or damaged housing must not be operated.
•The devices are intended for industrial use.

4Installation
Installation space requirements
Installation should be carried out by trained personnel.
Ensure that there is sufficient unoccupied space behind the installation
area before you drill or saw any openings. Please also observe the safety
information provided by the tool manufacturers.
CAUTION!
Solvents may emit fumes during sealing. Ensure that there is sufficient
ventilation and follow the instructions for using the sealing compound.
When choosing a location in which to install the fuel cell, please remem-
ber that the permitted operating temperature range for the device is
-20°C to +50 °C / -4°F to +122 °F.
CAUTION!
If the temperatures in the installation space exceed +50 °C / +122 °F the
EFOY Pro fuel cell will shut down and not produce energy.
As soon as the temperature in the installation space fall below +40 °C /
+102 °F the EFOY Pro fuel cell will start again fully automatic.
CAUTION!
The device requires an air supply and generates off-heat and exhaust
gases. The off-heat and exhaust gases must be released into the open air.
1. Opening for air supply for installation
space
2. Air supply for heat exchanger and for
stack
3. Off-heat from heat exchanger
(see chapter 4.3 "Connecting the off-heat
duct" on page 23)
4. Process exhaust air from stack
(see chapter 4.4 "Connecting the exhaust
hose" on page 25)

Installation
Page 20
1. Supply air
at least
ø10 cm / ø 3.95 in
2. Exhaust air
•The space in which the device is to be
installed (including safety distance)
must be at least L x W x H: 51 x 35 x 30
cm / 20.1 x 13.8 x 11.8 in.
•If the fuel cell is installed within a
sealed container, provide an opening
for supply air with a cross-section of at
least ø 10 cm/ ø 3.95 in – at structured
openings (fine grid, narrow gap), ac-
cordingly more.
•Use the off-heat duct to conduct the
off-heat out of the installation space
(see chapter 4.3 "Connecting the off-
heat duct" on page 23).
•The air openings of the installation
space need to be protected against the
penetration of water and foreign parti-
cles (e.g. using louvered metal sheets
and fly screens).
•Ensure that there is sufficient ventila-
tion in the installation space to prevent
heat build-up. This can be done with
additional openings or an additional
temperature-controlled fan.
•The electrical connections, the fill
opening for EFOY service fluid and the
fuel cartridge must be easily accessi-
ble.
