Preparing the installation

When installing the refrigerator, note the following:
To enable the refrigerant to circulate properly, the refrigerator may not
exceed an angle of 3° from level.
To achieve this, park the vehicle on a level firm surface. Ensure 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 recess dimensions are
(H x W x D in mm):
– Recess without flange: 1249 x 527 x 572 (fig. 1 A, page 2)
– Recess with flange: 1252 x 530 x 572 (fig. 1 B, page 2)
The outer wall must be fitted with an air inlet vent (fig. 2 1, page 2) and
an outlet vent (fig. 2 2, page 2) with ventilation grilles so that the heat
generated can be easily released to the outside:
– Lower air inlet vent LS300 must be installed as flush as possible to the
vehicle floor. Air inlet vent must have a minimum of 400 cm
area.
– Upper air outlet vent LS300 must be installed with the bottom of the
vent no lower than equal to the top of the refrigerator cabinet, the bot-
tom of the top vent can be higher than the cabinet.
Fit a heat conduction plate (fig. 2 3, page 2) above the refrigerator so
that the heat does not accumulate in the vehicle.
If the lower ventilation grille of the air inlet vent cannot be installed flush
to the floor, an additional inlet vent (fig. 2 4, page 2) must be provided in
the floor for releasing any possible gas leakage.
The distance between the refrigerator and the rear wall must be at least
10 mm.
A distance of more than 40 mm between the refrigerator and rear wall
leads to poor performance and increases the power consumption of the
refrigerator. Reduce the space behind the refrigerator to create adequate
air inlet and outlet ventilation corridor (fig. 4, page 3). Use a ventilation
plate, for example, to do this.
