applicable national regulations and standardsin force withregard
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 otherend of the flexible pipeto the
gas cylinder using a pressure reducing valve. The openings
through which the pipe passes must be fitted with abrasion
safeguards and all connectionsmustbe made using pipeclamps.
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 highup 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 thevehicle must be parked withthe 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. Werecommendfitting these covers “C”when the vehicle
is left idleduringthe winter period.

By insulating the rear part of the refrigerator from the living area,
sealing thestrips “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 T­extension “E” and relevant accessories (as shownin Fig. 4-D) and
it is possible to use the same grid for both the top and bottom
ventilation openingswithout 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 withdraft tube housing forthetop 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 warmertemperature, 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).

During journeys, when the vehicle is moving, GAS
power supply to the refrigerator is prohibited since
there is a riskthatthe flame may beextinguished.

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 tomake ice or to store frozen foods, according to the times
and methodsindicated onthe product. The compartment is not
suitable for freezing foods. By placing drinks in the low­temperature compartment, thefreezing processcould 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 shelfofthe freezer,this will create bettercontact with the
ice tray and thusspeedup 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 functioningof the refrigerator and toavoid 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 theice, as these could damage the appliance. When the
refrigerator has been defrosted,switchit 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 regularlythat the ventilation grids and the draft tube are not
blockedin any way.

When the vehicle isparkedandthe 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 placedinsidethe refrigerator.

Always use the stop to fix the door firmly into place
before moving the vehicle.

Prepare several containersof ice inadvanceand keep
in the freezer ratherthanmaking ice as required.
