Use a spirit level to check that the refrigerator is standing level in both directions. This is
important for satisfactory operation of the cooling unit
The absorption cooling unit is
cooled by convection and it is therefore vitally important that the
air circulates freely over the unit and that the air vent openings of the refrigerator are
always
kept open. The more ventilation you provide, the better the performance you can expect from
the refrigerator.
NOTFS;
KEEP APPLIANCE AREA CLEAR AND FREE FROM COMBUSTIBLE
MATERIALS, GASOLINE AND OTHER LIQ UIDS WITH FLAMMABLE VAPOURS.
DO NOT OBSTRUCT THE FLOW OF COMBUSTION AND VENTILATION AIR.
This refrige rator is designed for a self-contained fuel cylinder of not more than 75 cubic inches
(2 1/2 pounds nominal water capacity). The cylinder(s) must be made and marked in
accordance with the specifications for LP-gas cylinders of the US Department of Transportation
(DOT), DOT SPEC. 39 (49CFR 178.65). In Canada, with the Ministry of Transport and

Liquid Gas Operation:
The refrigerator may only be operated using a self-contained 14
or 16,4 oz propane HD 5 gas bottle, which is to be connected to
the refrigerator by means of-the supplied manual control valve
and the pressure regulator with hose.The gas burner is fitted
with a jet No. 21 which is suitable for use with Propane gas at
a supply pressure of 11 inches water gauge.
2.11
Connection of gas supply: (FIG.2 see page 9)
a: fix the cylinder holder (fig. 2.1);
assembly see FIG.4, page l0.
b:
fit the manual control valve (fig. 2.2) with pressure regulator (fig. 2.3) and hose to the self-
contained gas cylinder (fig. 24) finger tight.
c:
connect the gas hose to the inlet (fig. 2.5) at the back of the refrigerator.
d:
insert the gas bottle assembly into the gas cylinder holder (fig. 2.1).
Once connected all gas connections must be checked for leaks. This is done by placing a
soapy solution on all gas connections, turn on the gas cylinder manual valve and watch for
bubbles.
For the detection of leaks never use an open flame.
If the gas bottle is empty remove it from the bottle holder, unscrew the manual control
valve/pressure regulator-assembly from the bottle and fit a new one.

3. Electrical operation:
When running on electricity the cooling unit operates by means of two separate 75 W heating
elements, one for 120 V
a.c., the other for 12 V d.c..
a) 120 Volts a.c.:
Warning: Electrical earthing instructions:
This appliance is equipped with a three-pin (earthing) plug to protect you from shock
hazards and should be plugged directly into a properly earthed three-pin socket. Do not
cut or remove the earthing pin from this plug.
The lead is approximately 5 feet bng and an earthed three-pin socket should be installed
in an accessible position within reach of
the plug. Do not use any extension leads!
b), 12 Volts d.c.:
The current drawn is 7,O amps. If the box is run on the car battery it is recommended that
the refrigerator be operated only when the car engine is running. If the engine is stopped,
the car battery will lose power and become fiat.
The 12 V supply is protected by a fuse of maximum 10 amps.
The fuse-holder is fitted into the control panel. Check that a correct fuse
is installed.
4. Starting the refrigerator:
Do not operate the unit on two
or more power ‘sources (i.e. gas and 120 V or 12 V)
SIMULTANEOUSLY. The cooling unit will not operate properly in this case and damage may
be caused.

Propane gas operation-Lighting the burner:
open gas cylinder valve (fig. 2.2).
turn gas thermostat knob (fig. 2.6) in the clockwise direction to MAX setting
depress button (fig. 2.7) of flame failure safety device and keep it pressed down for about
20-30 seconds, the gas pipe to the burner is thus vented.
keep tie button (fig. 2.7) of safety device pressed down and ignite the burner by pressing
the piezogas lighter button (fig. 2.8) several times.
when the burner is lit, the red pointer of the flame in-
dicator is going from the white into the green field. When
the pointer is in the green field, keep knob (fig. 2.7)
pushed for another 20-30 seconds, then release it. Check
that the pointer remains in the green field. Check the
flame visually through the opening (fig. 2.9). If the flame
is not burning,repeat ignition procedure.
if, for any reason, the gas flame goes out, the flame safety device works automatically and
shuts off the gas supply. While the button (fig. 2.7) is depressed, this device is temporarily
inoperative.
when the refrigerator is no longer run on gas, turn off the gas supply at the gas cylinder.

4.2 Electric operation:
a:check the gas cylinder valve (fig. 22) is turned off.
b: connect to the electricity supply with the correct voltage;
for 120 V a.c. operation turn electric thermostat knob (fig. 2.10) in the clockwise direction
to pos. 7.
The 12 V circuit is not thermostatically regulated.
The knob (fig.
2.10) is useless for this energy source.
NOTE:
To stop the electrical 120 V a.c. operation, turn electric thermostat knob (fig. 210) in the
anticlockwise direction beyond the point where a slight resistance is felt, to 0 setting. For
safety reasons disconnect it as well. To stop the electrical V d.c. operation, disconnect
voltage supply.
5. Regulations of temperature:
After a sufficient period of maximum cooling set the appropriate thermostat knob to the middle
position. The cabinet will now automatically maintain a suitable temperature for ordinary food
storage. Usually, no further adjustment will be necessary, but in hot weather, or when more
cooling is required, the knob must be turned to a higher position. If less cooling
is required, the
knob should be turned to a lower position.
6. Storing food in the refrigerator:
To prevent food drying out and flavours being transferred from one food to another, foods
should always be stored in covered dishes, plastic bags or wrapped in foil or greaseproof
paper. NEVER PUT HOT FOOD INTO THE REFRIGERATORI Avoid using large dishes and
do not store food containers too closely together as this interferes with the circulation of cold
air within the cabinet.
7. Ice-making:
Fill the ice-tray with drinking water to within
1/5 of the top and cover with lid. Wipe off any
drops of water which may be on the tray and lid to prevent freezing together and place on the
shelf
directly beneath the refrigerating unit. Ice will be made more quickly when the thermostat
knob (6
or 10) is set to MAX (7) for a short time. When ice has formed, ensure that the knob is
returned to its normal setting.
TO remove the ice, allow the ice-tray to thaw slightly for a while or run it under tap water at
normal temperature before removing the lid from the tray. The ice cubes can now be removed
easily from the tray.
8. Defrosting:
Ice will form gradually on the cooling fins. It is a mistake to assume that an accumulation of ice
gives a colder cabinet For the most eff
icient and economical operation, the refrigerator should
be defrosted regularfy about every ten to fourteen days, depending on the particular
conditions of use. To defrost, turn off the gas cylinder valve or disconnect theelectricity supply
5

to the refrigerator, depending upon which energy source is used. Remove the ice-trays and
empty the refrigerator of food. Leave the cabinet lid open. The
ice will melt and drop into the
interior. When defrosting is completed, wipe the ice-tray support and the interior, dry carefully
with a clean doth.
NOTE:
Do not attempt to defrost more quickly by means of any form of heat, otherwise the plastic
surfaces may be damaged.
9. Cleaning:
Clean the refrigerator thoroughly, as necessary, partic ularly when it is not going to be used for
any length of fme.
First defrost the cabinet as described in the previous item, then dean the
cabinet interior and
lid with a clean cloth wrung out in warm water to which mild, unscented washing-up liquid has
been added. wipe over with a clean doth and dry thoroughly.
Do not place any plastic parts in water that is more than hand hot and do not expose them to
dry heat
The outside of the cabinet should be wiped with a dean, damp cloth and polished with a dean
soft duster.
NEVER USE STRONG CHEMICALS OR ABRASIVE CLEANING MATERIALS ON ANY
PART OF THE REFRIGERATOR.
10.What to do when the refrigerator is not
going to be used for a long time?
If you are not going to use your refrigerator for sometime, turn off the power supply (gas or
electric) and empty the box of its contents. Defrost refrigerator and carefully dean and dry
interior. To prevent any unwanted odour from forming in the interior, it is advisable to leave the
lid slightly open,
so that fresh air can circulate inside.
The ice-tray should be emptied, dried and replaced on the ice-tray support in the cabinet.
Points to remember!
l
lf the refrigerat or has teen out of use for a length of time, check connections for gas leaks
using soapy water
- see item 2. Liquid Gas Operation.
’
Never cover the air vents with cardboard or anything else.
l
Remember to level the refrigerator otherwise the cooling unit will not perform and could be
permanently damaged.
l
If possible pre-cool the refrigerator some hours before putting food in it.

Diinect all power supplies before servicing’.
LP. gas equipment:
The burner (fig. 3) is fitted with a jet No..21 which is suitable for use with Propane gas at a
supply pres sure of 11 inches, water gauge. The orifice in the jet is very small and must never
be cleaned by means of a pin or a
similar instrument, as this could damage the orifice. Should
the jet require deaning for some reason, it should be washed in alcohol and blown through
with air.
11.1 Cleaning gas burner and jet:
Once or twice a year, or depending on use, check whether the f&me is blue-coloured. For this
inspect the flame through burner flame opening (fig. 2.9) a yellow flame is sign of a bad
combustion. The procedure for cleaning the flue and the burner assembly, is as follows:
a:
b:
unscrew rear cover of refrigerator box.
disconnect and remove gas pipe from the burner. For this operation you need a 13/32" (10
mm) spanner for the union nut (fig. 3.1).

f:
g:
unscrew the coun ter nut (fig. 3.2) of the jet (fig. 3.3) with a 1/2" (12 mm) spanner and
remov e guard (fig. 3.4).
uns crew security-and guard plate (fig. 3.5,3.7) of the burner pipe (fig. 3.6) which are
fastened by a screw, push the burner pipe from the jet and remove the jet from the boring.
wash the jet with alcohol and blow through with air to check that the opening is quite
dean. Do not use a probe.
clean the burner pipe ensuring its combustion- and aeration openings are free from dust.
refit all parts, ensuring the burner is property retained. Gas connections should be tight,
but not overnight After replacing, check all gas joints for tightness as descrii in the next
item.
All instructions under item 11.1 must only be made by an expert, preferably by a
licenced gas fitter.
11.2 Checking for gas leaks:
Periodically, and after each service the entire gas installation should be checked for leaks. Test
all pipe connections with soapy water (not with a flame), watching for bubbles - see item 2
Liquid Gas Operation.
11.3 Heaters:
Heat is supplied to the boiler of the cooling unit by two separate 75 W heaters, one for 12 V
d.c. and one for 120 V a.c.. If a new heater has to be fitted, the procedure is as follows:
