information concerning environmental protection
TheFreezer / Refrigerator you have purchased is designed for operation from electrical mains, from a vehicle
battery or from bottled (LP) gas.
It can be used to transport frozen food or ice creme or as a normal refrigerator, depending on the settings (see
the relevant capitels).
Your portable Freezer/Refrigerator - in gas operation - must only be used in a wellventilated place, where it is protected from rain or water splashes. In electrical
operation, the appliance can be used in an enclosed area. However the appliance
must still be protected from moisture.
In this appliance the storage of any toxic or explosive substance is forbidden!
It is important in the interests of efficiency, to give the back of the unit as much
ventilation as possible to allow the heat to escape. The hottest spot is in the vicinity of
the burner, and particularly when operating on gas, it is essential that this place be
kept clear of any obstruction or flammable materials (e.g. grass or plastic ground sheets
that can burn).
In electrical operation, the appliance can be used in an enclosed area. However the
appliance must still be protected from moisture.

non-abrasive detergent. Ensure water does not
enter the rear cover grille or the control elements.
Afterwards, wipe the appliance with a clean towel
and cleanwater, and then wipe it dry.
To avoid damage, do not use soap, soda or
abrasive cleaners.
4. Positioning the appliance
During the refrigeration process, the appliance
gives off heat from the condenser (under the
upper part of the rear cover) into the surrounding air.
The more ventilated the condenser is, the more
effective the refrigeration will be.
The other condition for satisfactory operation is that
the appliance stands on a flat surface. This is best
seen by placing a glass of water on top of the
It is important that the appliance is not directly
exposed to radiated heat (sunlight, radiator, near an
oven, etc.).
In gas operation following clearances should be
kept from the walls or other materials: from the
back side of the appliance minimum 10cms, from
both sidewalls 4cms each, from the top of the
appliance minimum 30 cms, from the bottom
minimum 5cms.
In the immediate vicinity of the appliance within the
specified distances no inflammable matters (paper,
wood, grass, textile etc.) should be met with.
5. Using the appliance
The cable for mains connection, the 12V connecting
cable and the connector for the gas hook-up are
located on the rear cover of the Freezer / Refrigerator
(Figure 2).
5.1. Operating from electrical mains
Make sure the voltage shown on the data plate of the
appliance matches that of the mains voltage to which
you wish to connect the appliance. Pull out the mains
connecting cable and connect it to a receptacle
earthed socket for connection.
When connecting the appliance for the first time, set
the thermostat to maximum; then, after about five
hours, set it back towards minimum according to your
need of cooling. If you want to use the box as a freezer
(-12°C) then leave the thermostat setting on the
maximum, during the whole operation.
NB: Plug is provided according to specific
regulations in each country and may be different to
that shown.

vehicle battery
Make sure the voltage shown on the data plate of the
appliance matches the voltage of the vehicle battery
In 12V operation, the appliance runs continuously
without temperature control.
The appliance is supplied with a matching pair of
12 Volt MALE + FEMALE plugs (see 9,2
connection to vehicle power source).
For 12V operation, make sure, if the engine is not
running, that the plug must be disconnected (see
fig. 7). Otherwise, the appliance will discharge the
vehicle battery when in operation.

Operating from bottled gas
Connection to the gas cylinder is described in
sections 9.3. and 9.4.
After opening the valve of the gas cylinder and
checking for gas leaks turn thermostat to maximum
position (Figure 4), press down the gas safety valve
hold it down for about 10 seconds and then, press the
piezo-ignition button (marked with a star) several times
in quick succession. If the flame does not ignite, repeat
the process. (Air in the appliance gas line prior to
connection to the gas cylinder must be purged. Only
then can the gas be lit.)
Ignition of the flame can be verified through the flameview opening (Figure 5). After you have the flame
alight keep the safety gas valve pressed down for a
further 10 seconds.
The thermostat should be set to maximum to get the
freezer function (-12°C). To use the cooling function
the thermostat should be set towards minimum,
depending on the ambient temperature, to avoid
freezing of the goods.

6. Useful suggestions
When setting out on a trip, run the appliance on
230 V (in thermostat setting between “min” and
“max” for cooling and "max" for freezing) for 24
hours prior to departure. Place food in a precooled condition into the appliance.
Frost forms on the evaporator panel when in
operation. When opening the lid or putting in
food, some of this frost melts and collects in the
form of water on the bottom of the appliance.
Wipe the water off occasionally using a sponge.
Avoid putting foods with fragile packaging (such
as glass) into the refrigeration unit. Movements
and shaking of the unit may cause these items to
Once the Freezer/Refrigerator is in its
permanent position, make sure foods do not
come into contact with the evaporator panel, as
this can cause freezer-burn to the foods.
7. Defrosting, cleaning and
For defrosting, always unplug the appliance from an
electrical power source to avoid the risk of shock.
Make sure no other power source is connected (gas
or 12V). Remove food from the refrigeration unit and
leave the lid open. Depending on the temperature,
frost melts in a short time from the evaporator panel,
with water collecting at the bottom of the appliance.
Wipe it off using a towel. Afterwards, clean the
appliance by following the instructions in section 3.
Leave the lid ajar to prevent any odours from forming.

9.3 Connecting to gas cylinder
Make sure no other energy source is connected
(230V, 12V).
The unit must not be connected to town or natural gas
pipelines. It is only suitable for use with
propane/butane gas (e.g. Calor Gas, Camping Gaz,
Caravangas, etc.).
The freezer / refrigerator is equipped for a specific
gas-pressure, corresponding to the standard pressure
of the country in which it is sold. The rating-plate
states the pressure that is correct. It is important that
a non-adjustable pressure-regulator is used to reduce
the pressure in the gas cylinder to the operating
pressure specified on the rating-plate. No other
pressure may be used.
Needle valve-operated gas control taps are NOT
suitable for use with this appliance and must not be
used as a substitute for a pressure regulator.
Connection of gas supply
(The following instructions refer in the main to coolers
manufactured in the United Kingdom. For other
countries please refer to your supplier.)
Always connect in the following sequence:
To connect the appliance to the pressure-regulator an
APPROVED GAS TUBING should be used. This should
be minimum in length - have an inside dimension of
8mm and be marked BS3212/2/8.
The pressure-regulator must be compatible for Butane
11 in (28 mbar) or for Propane (37 mbar).
To connect the pressure-regulator to the gas bottle, the
valve of the gas bottle must be closed. After connecting
the pressure regulator to the bottle by screwing,
connect the two ends of the tubing to the nipples and
secure them with the two hose clipse. (Figure 9).
The gas bottle (Butane, blue bottle) may only be
used in an upright position and particular care must
be taken every time the appliance is connected to
the gas bottle to ensure that there are no leaks, that
the tubing (rubber hose) is not under tension or
kinked, and that it is not in contact with hot
The tubing and the gas bottle should always be
located in positions where they will not be tripped
over or otherwise inadvertently disturbed.
Before attempting to light the burner, every time
after connection, turn on the gas at the bottle and
check the gas connections for leaks by applying a
soap and water solution over them and watching for
bubbles, which would indicate a leak.
After testing dry off traces of detergent.
When fitting the connection to the gas inlet of the
appliance (Figure 8), hold the counterpart to avoid
straining and possibly damaging.
Figure 8.
For your safety:
Do not check for leaks with a naked flame!
