D. By heating the metal plate between the freezer and the fridge cabinet, the divider
heater prevents ice-forming when the freezer door is opened and also prevents
the freezer door from freezing stuck to the metal breaker of the fridge. To save
energy, the divider heater can be switched off. The switch can be found on the
side of the control panel near the latch.
5.3 Powering with electricity
Powering with electricity can be selected both by the Auto mode (only Automatic
fridges) and manually.
5.3.1 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
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 warns you whenever insufficient voltage is available or if a fault occurs. If
this happens, the LED will start flashing once per second and an error code is
shown in the LCD display.
When sufficient current is available again, or the fault has been resolved, the LED
will emit a steady blue light again.
Direct current (12V):
- Always use the gas connection or mains voltage to start up the refrigerator for the
first time and to cool it. Powering from the battery of your vehicle is suitable only
for maintaining the temperature of the refrigerator and its contents once it has been
refrigerated.
The 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 start
flashing once per second and an error code is shown in the LCD display.
Once the engine is running, or the fault has been resolved, or sufficient voltage is
available again, the LED will again emit a steady blue 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 (only Automatic fridges)
and manually.
Warning! - Flammable material must be kept away from the rear of 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.
- It is prohibited to use gas to power the refrigerator in the vicinity of petrol
stations.
The refrigerator only runs on liquid gas (propane, butane). It does not run on
natural gas or coal gas. Because liquid propane gas (LPG) burns differently than
other gases, please note that the burner has to be cleaned more frequently (the
recommended frequency is every six months).
From about 1000 m above sea level problems of a physical nature can occur when
lighting the gas (this does not mean that the refrigerator is not working properly!).
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
fridge is in Auto mode.
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,
- 8 -
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 start flashing every second and an error code is
shown in the LCD display.
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 and an error code is shown in
the LCD display.
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
- Push the main switch (A).
- The blue LED will go out.
- The refrigerator is now completely switched off.
- Use the special storage latch on the door locking mechanism to fixate the open
door. This prevents unpleasant odours and mould in the refrigerator.
6 MAINTENANCE
Regular maintenance is necessary to ensure the correct functioning of your
refrigerator.
6.1 Cleaning
Tip! A good time to clean your refrigerator is straight after you have defrosted it.
- Clean the refrigerator with a soft cloth and mild detergent.
- Dust the refrigerator with a soft, moistened cloth.
- Use a brush or soft cloth to remove once a year any dust from the condenser.
Important! - Do not use soap or aggressive detergents that are abrasive or
soda-based.
- The removable interior components of the refrigerator are not dishwasher proof.
6.2 Defrosting
Frost will gradually build up on the condenser of the refrigerator. You should defrost
the refrigerator as soon as the frost layer is about 3 mm thick. Frost reduces the
refrigerating capacity and life of your refrigerator.
- Remove the ice cube tray and all food.
- Switch off the refrigerator.
- Leave the refrigerator door open.
- Place dry towels in the refrigerator to absorb the water.
- Place trays containing hot water in the freezer compartment.
- After defrosting (when the freezer compartment and condenser are frost-free),
remove the towels and the water trays and use a cloth to dry off the refrigerator.
- Switch the refrigerator on again in the way described in section 4.1/5.2 ("Igniting
and starting your refrigerator").
