4.0 Refrigerator operation

The refrigerator is equipped to operate on
three power modes:
n
Mains voltage (230V AC)
n
Direct-current voltage (12V DC)
n
Gas (liquid gas propane/butane)
Select the desired power mode by the energy
selector switch (battery igniter type models)
or the energy selector button (MES, AES).
Appliances with automatic energy selection
(AES) are additionally provided with "automa-
tic mode" function. Then the AES system
automatically selects the best energy source
for each particular situation.
n
When the appliance is first put into operati-
on, there may be a mild odour which will
disappear after a few hours.
n
Park the vehicle level, particularly when
starting up the refrigerator and filling with
food before starting a journey.
n
The cooling unit is silent in operation.
n
The refrigerator will take several hours to
reach its operating temperature in the coo-
ling compartment. The freezer compart-
ment should be cold about one hour after
switching on the refrigerator.
4.1

Cleaning

Before starting up the refrigerator, it is recom-
mended that you clean it inside and repeat this
at regular intervals.
Use a soft cloth and lukewarm water with a
mild detergent. Then wipe out the appliance
with clean water and dry thoroughly.
Keep the condensation water drain channel
free of deposits.
To avoid material alterations, do not use soap
or hard, abrasive or soda-based cleaning
agents. Do not allow the door seal to come
into contact with oil or grease.
4.2

Maintenance

n
In compliance with the applicable regulati-
ons, please note that the gas unit and the
connected ventilation ducts must be chec-
ked by authorised technical personnel after
first use and after every other year for com-
pliance with the European Standard EN
1949. A test certificate has to be issued. It
is the user's responsibility to arrange
this test.
n
The gas burner must be inspected and
cleaned as necessary at least once a
year. When using liquefied petroleum
gas (tank or refill cylinders) the mainten-
ance interval is reduced to half-yearly or
quarterly.
Keep the evidence of maintenance work
carried out on your refrigerator.
n
Work on gas and electrical equipment
shall be carried out by qualified person-
nel only.
It is recommended that this is carried out
by an authorised customer services depart-
ment.
We recommend maintenance following an
extended shutdown of the vehicle. Please
contact our customer services.
