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).

UNIT VENTILATION

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.
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.

DISPOSAL OF COMBUSTION FUMES

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.

USE

Switching On

!
In order to operate, the refrigerator must
be connected to the 12 V DC current
directly from a battery (service).
The power source is selected by pressing button (3). Selection
occurs in the following sequence:
mains power (4), battery power (5), gas power (6).
(Fig.3)

Mains Power

Press button (3) until the indicator light (4) switches on. To
operate the refrigerator, it is necessary to provide a mains voltage
source. The electronic thermostat is enabled and can be set.
WARNING: Make sure that the gas safety device (9) is in
the OFF position.
These

Battery Power

Press button (3) until the indicator light (5) switches on. To
operate the refrigerator, it is necessary to make sure that a battery
is connected to the line input terminals operated by the key. The
electronic thermostat is automatically set to the maximum
temperature and CANNOT be adjusted.
WARNING: Make sure that the gas safety device (9) is in
the OFF position.
(Fig.3)

Gas power

Make sure that :
2
R
the safety valve on the gas cylinder has been opened and
that the cylinder contains gas;
R
the central valve on the vehicle (if fitted), is open.
In this position, the electronic card will only supply power to the
spark device that ignites the pilot flame. It is necessary to provide
a source of gas. When the gas operation mode has been
selected, if the indicator light (10) is off, this means that the burner
is operating normally; if the indicator light (10) flashes, this means
that the burner is at the ignition stage.
1 Press button (3) until the indicator light (6) switches on. The
indicator light (10) will start to flash.
2 Press the safety device (9) and turn it to the position marked
by the large flame.
3 Hold down the safety device knob (9).
4 When the indicator light (10) ceases to flash, wait 3-4
seconds and then release the safety device knob (9).
5 If the indicator light (10) continues to flash after 30-40
seconds, release the safety device knob (9) for a few
seconds and then repeat steps 3 and 4.
Gas operation is not possible if there is no direct battery
power supply (service).
