INSTRUCTIONS FOR USE
HOW TO START THE REFRIGERATOR
Leveling
In the boiler ammonia vapor is distilled from an ammonia-wa-
ter 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. e e the freezer shelf parallel to the floor, the refrige-
rator will then also perform well.
A bubble level should be placed on the freezer shelf. When
the vehicle is on tow, the continuous rolling and pitching
movement will not affect the refrigerator as long as the move-
ment passes either side of level, but when the trailer is tempo-
rarily parked this sensitivity of the refrigerator should be re-
membered. So, once more, before you start the refrigera-
tor make sure it is level.
Gas Operation (Fig. 4a) with piezo igniter
To start the refrigerator turn the knob A to position "GAS"
Turn the thenostat knob B to setting 4
Push the button C to stop and push the button D of the
piezo igniter. The pushing has to be repeated until the gas
is lit at the burner. This can be observed through the
reflector E
After the gas is lit keep the button C pushed for 10 se-
conds. Release the button and check through the reflector
that the burner flame stays burning. If not repeat the ligh-
ting procedure.
To shut off the refrigerator turn the knob A to off position.
NOTE: As soon as the necessary cold temperature in insi-
de the cabinet has been reached, adjust the ther-
mostat knob to required setting.
Gas operation (Fig. 4b)
with automatic reigniter
1.
To start the refrigerator turn the knob A to position gas
Lamp E comes on.
2.
Turn the gas thermostat knob B to setting 4.
3.
Press the button C to stop and keep it depressed. When
lamp E goes out wait 15 sec. and release button C. If the
lamp comes on again, repeat the procedure.
If flame blow out reignition will take place automatically.
To shut off the refrigerator turn the knob A to off position.
NOTE: After a replacement of the gas container or a long
shut off period the gas line is likely to be filled with
air. In such a case the lighting procedure has to be
repeated until the air is pushed out of the line and
the gas has reached the burner.
Flame Blow Out
If trouble is encountered with the flame blowing out under
specially windy conditions, try to avoid the wind blowing aga-
inst the wall where vent outlets are located. If the trouble
persists, set the thermostat to MAX. This later measure can off
course only be temporary such as when the vehicle is on tow,
for after a day or so at this setting the foodstuffs in the cabinet
will freeze.
Electric Operation (Fig. 4)
1. Check that the attachment plug is correctly connected to
the mains supply. When the refrigerator is equipped also
for 12 Volts D C operation the low voltage connection is
made at the marked terminals at the rear of the refrigerator
2. Turn the knob A to desired position for electric operation
3. Turn the thermostat knob B to setting 4
To shut off the refrigerator turn the knob A to off position.
HOW TO USE THE REFRIGERATOR
Food Storage Compartment
The food storage compartment is completely closed and un-
ventilated, which is necessary to maintain the required low
temperature for food storage. Consequently foods having a
strong odor or liable to absorb odors should be covered.
Vegetables, salads etc should be covered to retain their crisp-
ness. 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
Some refrigerator models are equipped with an automatic
defrosting device incorporated with the cooling unit. This devi-
ce makes a quick defrost of the finned evaporator section
about once a day without affecting the frozen food storage
compartment or the frozen foods contained in it. When the
frozen food storage compartment is covered with frost the
refrigerator must be shut down temporarily till the frost is
melted. Before the refrigerator is restarted the compartment
should be dried, the ice trays washed and refilled with fresh
water.
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.
Some refrigerators without the automatic defrosting device
should be defrosted regularly by turning off the refrigerator.
Empty the refrigerator leaving the drip tray under the finned
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 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.
