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)

To start the refrigerator turn the knob (A) to posi-

tion “GAS”.

Turn the thermostat knob (B)

quarter of a turn

from position “OFF”.

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).

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

To start the refrigerator turn the knob (A) to posi-

tion “GAS”. Lamp (E) comes on.

Turn the gas thermostat knob (B) a quarter of a

turn from position “OFF”.

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)

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.

Turn the knob (A) to desired position for electric

operation.

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.
