EFOY COMFORT fuel cells and EFOY fuel cartridges must not be stored at 
temperatures over 50°C/122°F and must not be operated at tempera-
tures over 40°C/104°F.  
Protect from heat and direct sunlight. 
Operate the EFOY COMFORT fuel cell only as specified in the installation 
instructions, and in a well-ventilated space. 
Keep EFOY COMFORT 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 COMFORT fuel cell or 
EFOY fuel cartridge. Protect from heat and ignition sources. Methanol is 
highly flammable! 
A methanol spillage (e.g. after an accident or in the event of damage to 
the EFOY COMFORT fuel cell or EFOY fuel cartridge) poses a fire hazard. 
Keep away from ignition sources and ensure good ventilation. 
Leakage of a small quantity of methanol will evaporate, leaving no resi-
due. 
Keep all EFOY COMFORT fuel cells and EFOY fuel cartridges out of reach 
of children, even when empty or only partly full. 
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 COMFORT fuel cells and EFOY fuel cartridges must be securely fas-
tened to prevent damage in the event of an accident. 
CAUTION! 
The EFOY COMFORT fuel cell is not water-tight! 
Ensure that no water can enter the fuel cell.
