Unit Ventilation; Disposal Of Combustion Fumes; Use; Switching On - Vitrifrigo Trivalente Series User, Maintenance And Installation Manual

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. 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.

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.

5.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).
Mains Power (Fig.3)
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.

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.
Gas power (Fig.3)
Make sure that :
the safety valve on the gas cylinder has been opened and that the
cylinder contains gas;
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).
