6.1 Description
The device can refrigerate goods to +8 °C to 0 °C and keep them cool. Products can
be frozen to –10 °C to –20 °C in the freezer compartment. You can use the control
display to set the desired temperature.
The refrigerator is suitable for use with 12 V or 24 V DC voltage and can therefore be
used e.g. for mobile homes, caravans or on boats. It can also be connected to a
100 – 240 V mains supply.
The refrigerator can withstand a short term inclination of 30°, for example on boats.
All materials used in the refrigerator are compatible for use with foodstuffs. The
refrigerant circuit is hermetically sealed and CFC-free.

7 Installing the refrigerator
7.1 Preparing the installation
When installing the refrigerator, note the following:
•Ensure that the floor is solid and level.
•Ensure that the refrigerator is level.
•The refrigerator must be installed so that it is easily accessible for service work,
easy to de-install and install and can be easily removed from the vehicle.
•The refrigerator must be installed in a recess so that it stands secure when the
vehicle is in motion. Note the following dimensions (fig. 3):

Installation with two rear vents
•The air inlet and outlet vents must not be covered by vehicle parts (such as an
open door or by installing accessories such as bicycle racks) while operating.
•Install the refrigerator so that it is protected from excessive heat, as this leads to
poor performance and increases the power consumption of the refrigerator.
•The electrical installation must comply with national and local regulations.

•The outer wall must be fitted with one air inlet ventilation grille (fig. 42a,
page 12) and one outlet ventilation grille (fig. 42b, page 12) so that the heat
generated can be easily released to the outside:
–LowerairinletventLS300canbeinstalled from flush to the vehicle floor up to
a maximum height (top of vent) of 300 mm below the compressor shelf.
– Upper air outlet vent LS300 must be installed with the bottom of the vent no
lower than the compressor shelf. Higher than the compressor shelf is
allowed, but for optimum service access as close as possible to the compres-
sor shelf height is recommended.

•Fit an air deflection plate (fig. 44, page 12) above the compressor so that the
heat does not accumulate in the vehicle.
Installation with one lower rear vent and one roof vent
INOTE
This installation method is satisfactory for refrigerator performance, but
not the preferred method due to lack of service access to the compres-
sor shelf area.

•A roof vent may be installed instead of the air outlet vent.
–Theroofventshouldbeinstalleddirectly above the back of the refrigerator as
far as this is possible. Use an air duct if you need to install the roof vent
(fig. 53) offset, otherwise heat will accumulate there.
7.2 Installing the refrigerator in a sealed location
separate to the living space
It is recommended to install the refrigerator in a sealed location in order to prevent
dust and heat from entering the living space of the caravan or motorhome.
A suitable seal must be provided and fitted to the bottom surface of the refrigerator.
The purpose is to provide a seal between the interior of the vehicle and the cooling
unit and ventilation area behind the refrigerator.
!
The manufacturer has applied a sealing strip to the rear surface of the front frame.
➤Apply a sealing strip to all four sides of the bottom surface of the refrigerator (1.
in fig. 6).
➤Push the refrigerator into position (2. in fig. 6). This then seals the space behind
the refrigerator to the interior of the vehicle.
WARNING! Fire hazard!
Do not use flammable materials such as silicone sealants, foam or similar
for the draught-proof installation.
