unavailable, the vehicle engine is running and a voltage higher than 11 V is

available.

If a fault occurs during electrical powering (230 V or 12 V), an error message will

not be shown on the display as long as another energy source is available. The

system will automatically switch to the available energy source that has the highest

priority.

5.3.2 Selecting electrical power manually

Mains voltage (230 V):

The LED on the main switch warns you whenever insufficient voltage is available

or if a fault occurs. If this happens, the LED will change from green to red and

flash once per second.

When sufficient current is available again, or the fault has been resolved, the main

switch LED will emit a steady green light again.

Direct current (12V):

The main switch LED warns you whenever your vehicle’s engine is not running,

or if a fault occurs, or if insufficient voltage is available. If this happens, the LED

will change from green to red and flash once per second.

Once the engine is running, or the fault has been resolved, or sufficient voltage is

available again, the main switch LED will again emit a steady green light.

NB: If the refrigerator has been manually set to operate at 12 V, it will not

automatically switch to another energy source when your vehicle’s engine is not

running. In this case, the refrigerator will stop cooling.

5.4 Powering with gas

Powering with gas can be selected both by the Auto mode and manually.

Warning! - Flammable material must be kept away from the refrigerator.

- For selection of gas type, see the information plate inside your refrigerator.

- For the pressure regulator model, see the information plate inside your

refrigerator and the table at the back of this booklet.

- The type of gas container and its location must be in compliance with the most

recent regulations. Ensure that the unit is installed in a location with good

ventilation and make sure that the ventilation openings in the gas container

storage location remain open.

- The changing of the gas container must be done outside in the open air and out

of reach of any possible sources of ignition.

- It is prohibited to use gas to power the refrigerator while you are driving. If a

road accident results in fire, there is a danger of explosion.

- It is prohibited to use gas to power the refrigerator in the vicinity of petrol

stations.

5.4.1 Auto mode

The system will select gas operation if:

- mains voltage (230 V) is unavailable;

- the vehicle’s engine is not running.

Once mains voltage (230 V) is available again or the vehicle’s engine is running, the

system will switch to the available energy source that has the highest priority.

If the refrigerator switches from 12 V DC to gas operation when it is in auto mode,

the system will wait for about 15 minutes before igniting the gas. During this time,

however, the gas indicator lamp will come on. The delay is built in to avoid it

switching to gas operation whenever you stop to refuel your vehicle. You can cancel

the delay by immediately switching the refrigerator off and then on again.

If the system selects gas operation, the ignition will be activated automatically. The

gas will flow to the burner and be lit by the electric ignition. If the flame goes out,

the gas will immediately be lit again.

5.4.2 Selecting gas operation manually

If the flame cannot be lit within 30 seconds, the gas supply will stop and gas

mode will be switched off. The LED of the main switch will turn from green to

red and flash every second.

The gas mode can be reset only if the refrigerator is switched off. If you switch the

refrigerator on again and the gas mode is still not working, the LED of the manual

gas mode will flash to indicate that gas is unavailable.

Important! It is prohibited to use gas to power the refrigerator while you are

driving. If a road accident results in a fire, there is a danger of explosion. It is

prohibited to use gas to power the refrigerator in the vicinity of petrol stations. If it

takes longer than 15 minutes to refuel your vehicle, you should switch the

refrigerator off using the main switch (A).

5.5 Switching off the refrigerator

- Set the main switch (A) to (off).

- The refrigerator is now completely switched off.

- Use the special storage latch on the door locking mechanism to stop the door

from closing. This prevents unpleasant odours and mould in the refrigerator.

6 SWITCHING ON THE REFRIGERATOR (control

panel according illustration 8)

- It is recommendable to clean the inside of the refrigerator before you switch on

the refrigerator.

- Let the refrigerator run for at least eight hours before you place food in it for the

first time.

6.1 Smart Energy Selection (SES)

When you start up the refrigerator (equipped with Smart Energy Selection (SES))

you should usually select the AUTO mode. The SES system will then automatically

select the best of the three available energy sources.

The system will apply the following priority:

- mains voltage (230 V)

- direct current (12 V)

- liquid gas

If an energy source becomes available that has a higher priority than the source the

refrigerator is currently using (e.g. if your vehicle engine is started), the system will

stop using the current energy source and switch to the energy source with the

higher priority.

If a fault occurs in one or more of the possible energy sources, the system will not

generate an error message while an alternative energy source is still available. The

SES system switches over automatically.

If none of the energy sources are available, the blue LED flashes every second

and an error code is shown in the display.

Automatic models additionally allow you to select the desired energy source

manually.

6.2 Switching on the refrigerator

Important! The memory of the SES system saves every change made to the setting.

Consequently, the SES system will start up on each subsequent occasion in the

last-selected setting.

1. Open the valve of the gas bottle.

2. Open the taps of the gas supply.

3. Press main switch (A). The function LED will turn blue and all symbols on the

LCD display will light up.

4. Use the mode selection switch to select the “Auto” function or one of the power

supplies that you want. The LCD display will show the option you have selected.

5. Set the desired refrigerating cooling level by means of the cooling level selection

switch (C). The LCD display will show the cooling level setting you have selected.

A. Use the main switch to switch the refrigerator on and off. The function LED will

turn blue. The display LCD shows the most recent settings.

After 10 seconds the LCD display’s backlight will go out. The function LED

remains blue.

B. Press the mode selector switch and the LCD display backlight will show the

setting for 10 seconds. Pressing the mode selector switch sucessive times takes

you through the menu in the following sequence: AUTO, manual DC (12 V),

manual gas, manual mains voltage (230 V) and back to AUTO. Select either the

AUTO option or one of the other power supplies that you want to use. The LCD

display shows the option you have selected. If you select the AUTO option, the

system will choose the most suitable power supply and the AUTO symbol and

the symbol of the power supply chosen by the system will both be shown on the

LCD display. Ten seconds after release of the mode selector switch, the system

will switch off the LCD backlight.

C. Use the cooling level selector switch to control the temperature of the

refrigerator. When you press the cooling level selector switch, the LCD backlight

will light up and show the currently set temperature. Every time you press the

cooling level selector switch again, you set the refrigerator one position cooler.

On reaching the coldest temperature, the system will start again at the warmest

temperature setting. Ten seconds after release of the cooling level selector

switch, the system will switch off the LCD backlight.

6.3 Powering with electricity

Powering with electricity can be selected both by the Auto mode (only Automatic

fridges) and manually.

6.3.1 Auto mode

Mains voltage (230 V):

This energy source will be selected if the mains voltage is greater than 200 V. This

power supply requires a continuous current of 12 V to operate the electronic

control system.

Direct current (12V) :

The SES system will select 12 V powering only if a mains voltage (230 V) is
