It may be necessary to use an external face plate to
protect the outlet. Use a suitable sealant to prevent
moisture from penetrating into the body or into the
interior.
4.5 Connecting the Exhaust Hose
Within the fuel cell methanol and oxygen are converted
into water and carbon dioxide. This chemical reaction
generates off-heat which needs to be conducted
together with water vapour and carbon dioxide to the
outside.
WARNING
Connect the enclosed exhaust hose and always
evacuate the exhaust gases from the installation
compartment or site to outdoors.
Exhaust gasses contain moisture and may exceed
60° C, causing scalding. Exhaust byproducts may
contain injurious substances. Avoid inhaling exhaust
directly or for long periods of time.
To prevent freezing in winter, the exhaust hose may
not too long and should be cut diagonally to avoid the
emergence of drops.
At no time may siphoning occur in the hose. Make sure
that the hose is neither clogged nor blocked.

Attach the exhaust hose (included) to the exhaust
port.
Take the exhaust hose out of the installation
space and seal the opening for the exhaust hose
with suitable sealing material. The exhaust
(which also includes condensate) can be directed
outside, to a wastewater tank or other suitable
container (on yachts also in the bilge). But make
sure that there is a hose that allows the gasses
including the carbon dioxide to evaporate.
The exhaust hose should be as short as possible.
The part of the hose at the outside should not be
longer than 5 cm. Cut diagonally the end of the
hose to avoid the emergence of drops.
The exhaust hose can be shortened as required.
The opening must have a diameter of 10 mm.

5.4 Automatic Operation
Automatic operation will begin the moment that you
connect the unit to a battery. The unit will monitor
battery voltage by itself.
The fuel cell switches on automatically if the battery
voltage falls below 12.3 V. The battery is then charged
until the deactivation threshold, 14.2 V, is reached.
Note: To guarantee optimal battery maintenance, it is
important that the charge current is not stopped
abruptly when the deactivation threshold is reached.
For this reason, the EFOY continues to charge for up to
3 h after the deactivation threshold set is reached (by
default, 14.2 Volt is preset). The recharging period
depends on the battery voltage and the electricity
consumption.
The device goes through a cold start phase of about
20 minutes before reaching its full rated output. In
normal operation the current generation is
interrupted briefly a few times a second.

5.5 Switching On the Fuel Cell
If desired, you can switch on the unit manually
regardless of the battery voltage. The unit will then be
in the “charging mode“.
This function is only possible when the battery voltage
is below 13.2V
On
Charging mode
Press on the control panel once if the unit has been
switched off, and twice if it is operating in automatic
mode. The unit will start up regardless of the battery
voltage and will continue charging until it reaches the
cutoff point
(U
batt
>14,2 V und I
out
< 2A – 4A for EFOY 2200).
The device will then switch to automatic mode by itself
and will only charge if the battery or the demand for
power requires it.

5.6 Switching Off the Fuel Cell
Press on the remote control to switch off the
device.
The unit will gradually shut down, performing various
function checks as it does so:
Off
Shutting down
To protect components, the unit must run at least
30 minutes before shutting down. If the unit is shut off
beforehand, it will continue running until 30 minutes
have elapsed. The message “Shutting down” will
appear in the display. Leave the fuel cartridge and the
battery connected during this time.
Please note that the fuel cell will only start up if it is
connected to an intact battery and full fuel cartridge.
The fuel cell will not switch on if the battery is
damaged.

5.7 Battery protection
Off
Battery protection
The EFOY fuel cell has an integrated battery protection
function. This function prevents deep discharge of the
battery when the operating mode is set to “Off”.
Battery protection is automatically activated when the
battery voltage is lower than 11.2 V for more than 15
minutes. The battery protection charging mode ends
when the voltage reaches 12.8 V.
This function only serves to protect the battery, and
does not recharge it.
Off
Battery protection -> to shut down
press off
Press the button to switch off the fuel cell after the
battery protection function starts. The function is
reactivated automatically when the unit is switched on
or operated in automatic mode.
Note: If you stop protective charging manually, battery
protection is deactivated until the fuel cell is started
again. Deep discharge can damage your battery. If
battery protection starts repeatedly, please check
your system.
Battery protection only functions when a full EFOY
fuel cartridge is connected.

5.8 Automatic Antifreeze Feature
Off
Antifreeze mode
This unit features an intelligent antifreeze feature. The
unit can keep itself warm at temperatures below 3° C
as long as it is connected to a working battery and it is
supplied with methanol.
If the unit is in antifreeze mode, the message
“Antifreeze mode” will appear on the second line. The
first line will indicate the current operating mode, for
example “Off”.
The antifreeze function works only as long as a fuel
cartridge and a sufficiently intact battery are
connected.
The unit will not be able to start if the battery voltage
falls below 10.5 volts. Please note that the unit will
not recharge the battery if the voltage drops below
10.5 volts.
CAUTION
Please observe the following maintenance tips for
storage and winter operation:
1 To cut energy costs, we recommend dismounting
the unit and storing it away from cold if it is to be
inactive for longer periods of time. Dismounting is
easy; it requires just a few steps, no tools and no
particular technical finesse. Store the unit in the
original carton.
2 If, despite precautions, the unit does freeze, let it
thaw in a warm place for approximately 24 hours
before operating. Please note that the unit’s
performance may diminish if it freezes
repeatedly.
Running in straight antifreeze mode, the unit will
consume approximately 10 liters of methanol in the
course of a five-month Central European winter.

remote control.
Store the plugs and lines in a cool, dry place.
WARNING
Do not smoke when handling unit and fuel
cartridge. Keep away from open flame!
Unscrew the fuel cartridge and close it with a cap.
Keep all elements clean.
WARNING
Keep unit and fuel cartridges – even empty or
partially empty cartridges – away from children
Remove the exhaust hose. Keep it clean and place a
cap over the exhaust outlet.
Remove the off-heat tube and the off-heat bow if
necessary.
Release the belt and lift the unit off the mounting
plate.
CAUTION
Store the device in a cool place but over 1 °C, since
the automatic frost protection system only
functions with connected fuel cartridges and
sufficiently charged batteries. (see Section 5.8)
5. Operation
38
CAUTION
If the device is exposed to temperatures below
0 °C without connected batteries and sufficiently
filled fuel cartridges (frost protection), it must be
thawed out for approximately 24 hours at room
temperature before commencing operation.
When transporting the device, use suitable
packaging, e.g. the original packaging, and cushion
the device to protect it from shocks. The device must
be standing upright when transported.
