SPECIAL HINTS
Note. Do not install the appliance directly on carpeting.
Carpeting must be protected by a metal or wood panel
beneath the appliance which extends at least full width and
depth of the appliance.
The refrigerator must be installed in a substantial
enclosure and must be level. A spirit level is supplied
with each refrigerator and by placing it in the freezer compartment one can level the refrigerator both ways front to
back and side to side. When installing the refrigerator in
the enclosure care should be taken to ensure a complete
sealing between the front frame of the refrigerator and
the top, sides and bottom of the enclosure. For this
purpose a length of sealing strip is applied to rear surfaces of the front frame. A sealing strip should also be
applied to the foremost floor of the enclosure as shown
in fig 8. The sealing strip should provide a complete isolation of the appliance combustion system from the vehicle
interior.
Be careful not to damage the sealing strip applied to the floor of
the enclosure when the refrigerator is put in
In the front frame and in the base at the rear of the refrigerator
there are holes for screws for fixing the refrigerator in the enclosure. See fig. 9.

INSTRUCTIONS FOR USE
HOW TO START THE REFRIGERATOR
Leveling
In the boiler, ammonia vapor is distilled from an
ammonia-water mixture and carried to the finned condenser, where it liquifies. The liquid flows to the
evaporator, where it creates cold by evaporating into a
circulating flow of hydrogen gas. If the evaporator coil is
not level the liquid readily accumulates, forming pockets
which can impair the gas
which case, of course, the cooling will stop.
When the recreational vehicle is stationary it must be
leveled to be comfortable to live in. If the refrigerator is
properly installed, the freezer shelf parallel to the floor,
the refrigerator will then also perform properly. A bubble
level should be placed on the freezer shelf. When the
vehicle is in tow, the continuous rolling and pitching
movement will not affect the refrigerator as long as the
movement passes either side of level, but when the trailer
is temporarily parked this sensitivity of the refrigerator
should be remembered. So
the refrigerator make sure the recreational vehicle is
leveled to be comfortable to live in.

HOW TO USE THE REFRIGERATOR
Food Storage Compartment
The food storage compartment is completely closed and
unventilated, which is necessary to maintain the required
low temperature for food storage. Consequently foods
having a strong odor or those liable to absorb odors
should be covered. Vegetables, salads, etc. should be
covered to retain their crispness. The coldest positions in
the refrigerator are underneath the cooling evaporator
and at the bottom of the refrigerator, and the least cold
positions are on the upper door shelves. This should be
considered when different types of food are placed in the
refrigerator.
Defrosting
Shut off the refrigerator.
Empty the refrigerator, leaving the drip tray under the fin-
ned evaporator and the cabinet and freezer doors open. If
desired, defrosting may be speeded up by filling the ice
tray with hot water and placing it in the freezer.
When the frost on the finned evaporator section has
melted water will be collected in the drip tray. The drip
tray should be emptied at regular intervals.
When all frost is melted, empty the drip tray and dry the
interior of the refrigerator with a clean cloth.
Replace the drip tray and ice tray, replace all food stuffs
and set the thermostat knob to its normal position.
NOTE: After a replacement of the LP Gas bot-
tles or a Ion period with refrigerator
off, the gas

procedure has to be repeated until the
air is pushed out of the line and the
gas has reached the burner.
Pme is likely to be filled
Frozen Food Storage Compartment
The ice trays should be placed in direct contact with the freezer
shelf for fastest ice making. Quick frozen soft fruits and ice cream
should be placed in the coldest part of the compartment which is
at the bottom of the aluminium liner or, in models with a shelf, on
this or just below it. Frozen vegetables, on the other hand, may
be stored in any part of the compartment.
The compartment is not designed for the deep or quick
freezing of foodstuffs. Meat or fish foods, whether raw or
prepared, and provided they are pre-cooled in the
refrigerator, can however, also be stored in the frozen
food storage compartment. They can then be stored
about three times as long as in the fresh food storage
compartment. To prevent drying out, keep food in covered
dishes, in plastic bags or wrapped in aluminum foil.
Ice Making
Ice cubes can be made in the ice trays which should be
filled with water to within
ice cubes seize the tray with both hands and twist the
tray. Cubes not required should be replaced in the tray.
Refill the tray with water and replace the tray on the
freezer shelf.
Ice making is accelerated if the thermostat knob is turned to
setting “MAX”. It is a good idea to do this a few hours before an
anticipated need for ice but be sure to turn the knob back to
normal setting when the ice is formed or the foodstuffs in the
cabinet may become frozen hard.

At OFF
The Flame Failure Safety Device
The tip of the thermo-couple must reach in over two
slots of the burner. To replace the thermocouple proceed as follows:
1.
Remove the cover
Unscrew plug and pull thermocouple straight out.
2.
Remove spring.
3.
4.
Pull out thermocouple sideways from burner housing.
5.
Bend the new thermocouple to the same shape as
the old one.
6.
Reassemble in reverse order. Check that the tip has
been correctly refitted in relation to burner.
7.
Mount plug, taking care not to damage the threaded
hole in the aluminum cap of the housing. The plug
must be properly tightened to the valve housing to
ensure good contact between the thermocouple and
the magnetic coil within the housing.
The Thermostat
The refrigerator is equipped with a thermostat which is regulated
by turning the knob to different settings in order to obtain the
Under normal operating conditions the thermostat
valve remains closed and the burner is running continuously at the by-pass rate, just enough to keep the
burner lit.
To Shut Off the Refrigerator
To shut off the refrigerator turn the knob (A) to off position. If the cabinet is not in operation over a period of
weeks, it should be emptied and cleaned and the door left
ajar. Some models are provided with interior light, which
comes on when the door is opened. To avoid discharging
the battery, the light should be shut off. Use tape to close
the switch or remove the lamp. The ice trays should also
be dried and kept outside the cabinet.
Cleaning
To clean the interior lining of the refrigerator use lukewarm weak
soda solution. The evaporator, ice trays and shelves must,
however, be cleaned with warm water only. Never use strong
chemicals or abrasives to clean these parts or the protective
surface will be spoiled. It is important always to keep the
refrigerator clean.
Do not store explosive substances in the refrigerator
such as cigarette lighter fluid, gasoline, ether or the

At MAX
The thermostat valve remains open and the burner is
running continuously at full gas rate. Lowest cabinet
and freezer temperatures are obtained at this setting.
Between these two extremes of the dial various controlled temperatures can be obtained, by turning the
thermostat knob to a suitable position. The closer to
MAX the lower the temperature. As soon as the required cold temperature inside the cabinet is reached,
the thermostat cuts the burner main flame leaving the
by-pass flame to keep the safety valve open.
The Igniter
The refrigerator is fitted either with a piezo igniter (see fig. 1) or an
automatic reigniter (fig. 2 and 3) which does not normally need
any maintenance. If the igniter does not work properly contact an
authorized service center.
ELECTRIC EQUIPMENT
Cartridge heater
The refrigerator is equipped also for electric operation. Many
models are equipped for both 120 Volts A C and 12 Volts D C
operation.
The heat necessary for the operation of an absorption
type cooling unit is supplied by an electric heater
mounted in a pocket of the boiler system.

To replace the heater, first of course check that the wall
plug is disconnected. If the refrigerator is equipped for 12
Volts D.C. operation, make sure that the 12 V leads are
disconnected. Then proceed as follows:
