INFO:
Please check your system if the fuel cell repeatedly switches back to
battery protection. Either the battery has already been damaged or too
much energy has been discharged.
INFO:
Battery protection only works if a full EFOY fuel cartridge is connected.
3.6 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, even if the fuel cell is in "Manual Off"
operating mode. This prevents the device from
freezing. 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. The automatic anti-
freeze feature does not run if the voltage drops below 9 V and the device
is switched off.
Please note that the EFOY COMFORT fuel cell must be protected against
frost. Repeated freezing may cause irreversible damage to the device.
INFO:
For a five-month winter period in Central Europe, the device requires
approx. 10 liters/2.64 gallons of methanol in antifreeze mode.
INFO:
If you do not use your vehicle/boat in winter, you can also remove the
EFOY COMFORT fuel cell and store it in a warm place (see chapter 3.3
"Shutdown and dismantling" on page 73).
