SPECIAL HINTS
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.
Any space between counter or storage area and the top of the
refrigerator greater than 1

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 circulation or even block it,
in 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, i e
the freezer shelf parallel to the floor, the refrigerator will then also
perform well.
A bubble level should be placed on the freezer shelf. When the
vehicle is moving, the continuous rolling and pitching movement
will not affect the refrigerator as long as the movement passes
either side of level, but when the RV is temporarily parked this
sensitivity of the refrigerator should be remembered.
So, once
more, before you start the refrigerator make sure It Is level.
Operation
Before starting the refrigerator check the gas valves in the piping.
Do not forget the valve on the back of the refrigerator.
1.
To start the refrigerator turn knob A to position On. Lamp E

2. Turn the thenostat B to a suitable setting, try 4.
3. The fridge is shut off by turning knob A to position Off.
Information on the operation of

There is no by-pass flame on these
refrigerators
The control system shuts off the gas when the refrigerator has
correct temperatures. The gas flame will be lit by the control
system when the temperature increases above the preset one.
Delay
for gas start up
In order to avoid a gas-flame at gasoline stations the refrigerator
30
is programmed to delay gas start up for about
operation. Please observe that this delay occurs even after only
1 minute of 12 V operation from your engine in order to cover
events when you have to wait in line for a gasoline pump. If you
want a quick gas start up after 12 V operation you can switch off
the refrigerator for a few seconds and then switch back to on.
Note: This operation is only avaible when the refrigerator is
connected for three-way use, see p. 4 12 V operation.

Note. The first start is always a problem. To empty the gas pipe
from the gas vessel up to the refrigerator may take several
minutes - i e 3-4 operations as to point 1.
Electric operation and selection of electric operation is not
blocked during red flashing light. Gas operation can only start
after ON - OFF - ON OPERATION
The red flashing light indicates faulty operation. If you will operate
the refrigerator on any electrical source connect and supply the
avaible voltage and make an ON-OFF-ON operation. Please
remain in the OFF position as long as the red light flashes.
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
or 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
Empty the refrigerator leaving the drip tray under the finned
evaporator and the cabinet and freezer
defrosting may be speeded up by filling the ice tray with hot water
and placing it in the freezer.
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 to MAX for a few hours. Then reset the thermostat
knob to its normal position.
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 aluminum 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
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
dishes, in plastic, bags or wrapped in aluminum foil.

water to within
seize the tray with both hands and twist the tray. Cubes not
required should preferably 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.

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. 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
