HOW TO START THE REFRIGERATOR
Leveling
In the boiler, ammonia vapor is distilled from an
ammonia-water mixture and carried to the finned con-
denser, 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 curculation 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, 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
once more, before you start
the refrigerator make sure the recreational vehicle is
leveled to be comfortable to live in.
Gas Operation with piezo igniter (Fig. 1)
1. To start the refrigerator turn the knob (A) to posi-
tion “GAS”.
2. Turn the thermostat knob (B) a quarter of a turn
from position “OFF”.
3. 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 observ-
ed through the reflector(E).
4. After the gas is lit keep the button (C) pushed for
10 seconds. Release the button and check through
the reflector that the burner flame stays burning. If
not, repeat the lighting procedure. To shut off the
refrigerator turn the knob (A) to off position.
Gas Operation
with automatic reigniter (Fig. 2 & 3)
1.
To start the refrigerator turn the knob (A) to posi-
tion “GAS”. Lamp (E) comes on.
2. Turn the gas thermostat knob (B) a quarter of a
turn from position “OFF”.
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 blows out, reignition will take
place automatically. To shut off the refrigerator
turn the knob (A) to off position.
Electric Operation (Fig. 1,2,3)
1. Check that the 120 Volt plug is correctly connected
to the main supply. When the refrigerator is equip-
ped for 12 Volt D.C. operation the low voltage con-
nection is made at the terminals marked at the rear
of the refrigerator.
2. Turn the knob (A) to desired position for electric
operation.
3. Turn the thermostat knob (B) a quarter of a turn
from position “OFF”.
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
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
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.
