5.6 Automatic antifreeze feature
The device has an intelligent automatic antifreeze
feature. This operating status switches on auto-
matically as soon as the temperature drops below
+3°C/ +37.4°F. This prevents the device from freez-
ing. If the device is operating in antifreeze mode,
the message "Antifreeze" is shown in the second
line of the display.
CAUTION!
The automatic antifreeze feature only works when the fuel cell is con-
nected to a filled EFOY fuel cartridge and an intact battery.
For a five-month winter period in Central Europe, the device requires
approx. 10 liters/2.64 gallons of methanol in antifreeze mode.
