2.6 Appliances with electronics
(MES/AES)
Car manufacturers often use a so-called bat-
tery management system, which provides the
caravan with constant voltage in trailer mode.
If the car and trailer remain parked for more
than 30 minutes with the engine switched off,
the battery management system automatically
switches off the permanent positive supply to
the caravan (to prevent the battery from disch-
arging). Fridges with control electronics
(MES/AES) are then inoperative.
Check whether your drawing vehicle is equip-
ped with a battery management system.
A permanent 12V power supply must be
guaranteed for operation of the MES/AES
fridges.
It is imperative that the operating pressure of
the pressure reducer on the gas system corre-
sponds to the data specified on the rating
plate of the refrigerator. Compare the opera-
ting pressure of the rating plate with the data
specified on the pressure reducing valve of the
liquid gas cylinder.
2.7 Operating the refrigerator
with gas
WARNING!
Operating the appliance with gas is
not permitted
n at petrol stations
n on ferry boats and on board motor rail
trains
n while transporting the caravan/motor-
home by a transporter or breakdown
vehicle.
There is the danger of fire!
Switch off the appliance.
If you smell gas:
n Open all windows and leave the room.
n Do not operate any electrical equipment
and prevent the use of naked flames.
n Do not operate any electrical equipment
and prevent the use of naked flames.
n Contact authorised specialist personnel*
for advice.
* authorised specialist personnel
Authorised specialist personnel are accredited
experts who are able, by virtue of their training and
knowledge, to vouch that the inspection and repair
work has been carried out properly.
Dometic refrigerators are equipped for a con-
nection pressure of 30 mbar. For connection
to a 50 mbar gas system, use Truma VDR
50/30 medium pressure controller.

Ammonia is used as a coolant.
This is a natural compound also used in hou-
sehold cleaning agents (1 litre of Salmiak
cleaner contains up to 200g of ammonia -
about twice as much as is used in the refrige-
rator). Sodium chromate is used for corrosion
protection (1.8% by weight of the solvent).
WARNING!
n Switch off the appliance.
n Open all windows and doors to ensure
ventilation.
n Leave the living area.
n Inform the authorised Dometic custo-
mer service.
