BOXING IN
DOOR REVERSAL
The refrigerator must be inserted into a compartment of
adequate dimensions (see Table 3) – without forgetting that there
must be an all-round gap of no more than 3 mm between the
appliance and the compartment. Ensure that the compartment
is:
perfectly regular and with a flat bottom for problem-free
appliance slotting in or removal;
sufficiently sturdy to sustain the weight of the refrigerator
when full, taking into account the stresses caused by the
vehicle when it is in motion.
Before inserting the refrigerator into the compartment, fix strips to
the sides “A” (as in Fig.4) using an elastic bonding agent.
Insert the appliance into the compartment, ensuring that it is
perfectly aligned and that nothing protrudes. Also make sure that
there is a gap of 10-20 mm between the vehicle wall and the
refrigerator unit in order to permit the correct ventilation of this
latter (see Fig. 4).
Use screws to fix the refrigerator firmly to the sides of the
compartment “A” (as in Fig. 5). The screws should be suited to
withstand strain, not forgetting the stresses caused by the vehicle
in motion and should be inserted in the holes “B” made inside the
unit (as in Fig.5). Use the cap supplied to close the holes “C” (as in
Fig. 5).

applicable national regulations and standards in force with regard
to: “Standards for the safe use of combustible gas ”, “Standards
for combustion appliances and ventilation devices on road
vehicles”.
The gas connection to the refrigerator must be made using an
approved flexible pipe for LPG. This hose must be no more than
1.5 m in length and the connections must comply with those of
the destination country. To ensure that the pressure of gas
entering the refrigerator is equal to that shown on the rating label,
it is necessary to connect the other end of the flexible pipe to the
gas cylinder using a pressure reducing valve. The openings
through which the pipe passes must be fitted with abrasion
safeguards and all connections must be made using pipe clamps.
Furthermore, an approved shut-off valve must be fitted (in
accordance with the standards and regulations in force in the
different countries).
Optimum refrigerator operation is guaranteed by adequate
ventilation, which occurs through two openings “B” (Fig.4) to be
made on the upper and lower part of the vehicle. These
openings allow air flow re-circulation: air enters through the
bottom opening and warm air is discharged through the top
opening.
The top opening must be positioned above the condenser and
as high up as possible (as shown in Fig. 4). The bottom grid must
be flush with the base of the refrigerator (Fig. 4). In the event of
wind, the grid “I” must be covered with mosquito netting on the
inside, as well as with the winter shield (not supplied with the
refrigerator) “C”, or the vehicle must be parked with the openings
downwind.
The surfaces that allow air to enter must be at least 250cm and
equipped with the proper grids “I” with sufficient heat resistance
qualities.
During winter periods, it is advisable to fit the protective covers
“C” in order to prevent air that is too cold from entering into the
system. We recommend fitting these covers “C” when the vehicle
is left idle during the winter period.
By insulating the rear part of the refrigerator from the living area,
sealing the strips “A” properly (as shown in Fig. 4), and applying a
sheet of aluminium “D” (as shown in Fig. 4-C) exhaust fumes and
currents of cold air from the outside are prevented from entering
the vehicle and at the same time adequate heat insulation is
guaranteed. In this way it is no longer necessary to use the T-
extension “E” and relevant accessories (as shown in Fig. 4-D) and
it is possible to use the same grid for both the top and bottom
ventilation openings without the housing for the draft tube. If the
rear part of the refrigerator is not insulated or no aluminium sheet
“D” is applied as shown in Fig. 4-C, fit the T-extension “E”, the
extension “F”, cap “G” and cover “H” (as shown in Fig. 4-D) and
use the grid with draft tube housing for the top opening.

Refrigerator Operation
R
R
Adhere strictly to the indications given
here below.
For the best performance of the
refrigerator, ensure that it has been
properly levelled.
The refrigerator is equipped with an electric thermostat and
multiposition gas-operated valve for temperature adjustment.
GAS OPERATION
The temperature is set using the safety device (9). To obtain a
cooler temperature, the knob must be set to the large flame, while
for a warmer temperature, it must be set to the small flame.
MAINS POWER OPERATION
The temperature is set using the thermostat (8) in the right-hand
section of the control panel.
The thermostat can be set to any of 7 pre-set temperatures, which
are shown by 4 LEDs.
The first LED on the left represents the highest (warmest)
temperature.
The button (7) is used to vary temperature settings; each time that
it is pressed, the lit LEDs will change and the temperature inside
the refrigerator will change as a result.
Once the lowest (coolest) temperature has been reached (last
LED on the right switched on), when the button (7) is pressed
again, the thermostat will return to the highest (warm)
temperature (last LED on the right lit).
BATTERY OPERATION
When using the refrigerator with battery power, it is not possible
to set the temperature. In this case the thermostat is set to the
lowest (coolest) temperature.
SWITCHING ON THE FAN
The fan is switched on by pressing button (1). When the fan is
working, the indicator light (2) is switched on.
The fan can be operated using any power source, although
operation is only possible if there is a direct power supply from
the service battery (V DC).
(Fig.3)
FOOD CONSERVATION
Most foods carry storage instructions. Always respect these
indications. It is good practice to store foods in closed
containers. Do not place warm food inside the refrigerator; wait
until it has cooled. The low-temperature compartment can be

During journeys, when the vehicle is moving, GAS
power supply to the refrigerator is prohibited since
there is a risk that the flame may be extinguished.
During storms or in the presence of strong winds, it is
better not to use the GAS power supply to the
refrigerator, since there is a risk that the flame may be
extinguished.

used to make ice or to store frozen foods, according to the times
and methods indicated on the product. The compartment is not
suitable for freezing foods. By placing drinks in the low-
temperature compartment, the freezing process could cause the
containers to break.
Ice should be made at night when the refrigerating unit is
subjected to a lower workload. Fill the container “A” (Fig. 6) to the
brim with water (if the ice is for human consumption, ONLY use
drinking water) and place in the freezer. If a little water is poured
onto the shelf of the freezer, this will create better contact with the
ice tray and thus speed up ice production.
The refrigerator should be defrosted each time that there is more
than 3 mm of ice. This operation is necessary to guarantee the
correct functioning of the refrigerator and to avoid higher levels of
energy consumption. For full defrosting, press the power
switch(Fig.3), switch off the refrigerator and shut off the gas cock
(Fig.3). Keep the refrigerator door open to speed up the
defrosting time. Do not use sharp, pointed tools or knives to
remove the ice, as these could damage the appliance. When the
refrigerator has been defrosted, switch it on again.
During winter it is advisable to apply protective panels to the
ventilation grids in order to limit the flow of cold air to the
refrigerator. It is possible to order a special protective panel for
the winter for ventilation grids supplied by Vitrifrigo. When the
outside temperature drops to below 0°C, winter protective
panels should be used. When the vehicle is out of use for any
period of time, it is advisable to fit protective panels to the
ventilation grids.
Check regularly that the ventilation grids and the draft tube are not
blocked in any way.
When the vehicle is parked and the engine is switched
off, switch off the battery power supply to the
refrigerator since the charge will finish in a very short
period.
To improve the performance of the refrigerator,
defrost it on a regular basis and never obstruct the
ventilation openings.
All strong-smelling products should be firmly closed
before they are placed inside the refrigerator.
Always use the stop to fix the door firmly into place
before moving the vehicle.
Prepare several containers of ice in advance and keep
in the freezer rather than making ice as required.
