(230 V), manual gas and back to AUTO. Select either the AUTO option or one of
the other power supplies that you want to use. The LEDs show the option you
have selected. If you select the AUTO option, the system will choose the most
suitable power supply and the AUTO LED and the LED of the power supply
chosen by the system will both light up. Ten seconds after release of the mode
selector switch, the system will switch off the LEDs. They will go out.
C. Use the temperature selector switch to control the temperature of the
refrigerator. When you press the temperature selector switch, the LED showing
the currently set temperature will light up. Every time you press the temperature
selector switch 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 temperature selector switch, the system
will switch off the LEDs. They will go out.
5.3 Powering with electricity
Powering with electricity can be selected both by the Auto mode 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.
GB
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! You are strongly advised not 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 0 (off).
- The refrigerator is now completely switched off.
- Use the door locking mechanism to lock 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.
- 4 -
- Use a brush or soft cloth to remove once a year any dust from the condenser at
the inside of the refrigerator.
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 in the way described in section 4.2 ("Switching 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 ("Igniting
and starting your refrigerator").
Important! - Do not use force or sharp objects to remove frost.
- Do not try to accelerate defrosting by using (for example) a hairdryer.
6.3 Door locking mechanism
Frost will form in the refrigerator if the door is not closed properly. To determine
whether the door closes properly, close the door with a piece of paper between the
door and the refrigerator. Pull at the piece of paper. If you feel resistance, the
refrigerator door closes properly. If you feel no resistance, the door does not close
properly. Perform this test regularly on all four sides of the refrigerator door.
If you find that the door does not close properly, check whether the door locking
mechanism keeps the door properly shut.
6.4 Winter operation
If you use the refrigerator when the outdoor temperature is below 8°C, install the
Thetford winter cover (see illustration 6) on the ventilation grills. The cover protects
your refrigerator from excessively cold air. The winter cover is a refrigerator
accessory obtainable from your caravan dealer.
Tip! It is advisable to use the winter cover if you are not going to use the vehicle for
a long period of time.
6.5 Maintenance of gas equipment
A qualified service engineer must maintain and inspect gas and electrical
equipment. It is advisable to have this maintenance work performed by a customer
service centre. Contact the Customer Service department of Thetford for a list of
qualified parties.
Important! European laws covering gas appliances and extractors prescribe
observance of the following rules (which are the user's responsibility):
- appliances that run on liquid gas must be inspected before being used for the
first time and every year thereafter.
- the gas burner must be cleaned at least once a year or more frequently if necessary.
- If a gas hose is used, it must be checked annually. This hose has a limited life
and, thus, must be regularly replaced. Check the hose regularly for cracks, splits
and ageing. If in doubt, replace the hose. Pay attention to the maximum life of
the hose and replace it in time, as advised by the manufacturer or in
