OPERATING INSTRUCTIONS

LP GAS OPERATION

Before starting the refrigerator, open the shutoff valve of

the gas bottle (check that there is enough gas).

Open any on-board shutoff valve.

1. To start the refrigerator, turn knob A to position

(GAS).

2. Turn the thermostat knob B to position 4.

3. Push the button C in until it reaches the bottom -

and hold, push the button D for the piezo igniter

several times to light the burner. This can be

observed on the flame indicator E. When the flame

is on, the red indicator is in the green field. (ON).

4. After the gas is lit keep the button C pressed for 10

seconds. Release the button and check that the

RED indicator is in the GREEN field, (ON).

5. To shut off the refrigerator turn the knob A to OFF

position.

NOTE: After changing an LP tank, or after a long shut

off period, the gas line is likely to be filled with air. You

may have to repeat the lighting procedure several times

to purge the air out of the gas lines.

! WARNING

DO NOT OPERATE THE REFRIGERATOR ON LP

GAS WHILST TRAVELLING.

230-240 V AC OPERATION

Before operating the refrigerator , check that the voltage

stated on the data plate is the same as the main voltage

in use.

1. Check to be sure that the power cord is properly

connected to the power supply. (See FIG. 8).

2. Turn the knob A to the position marked AC for

230-240 volt AC operation.

3. Turn the thermostat knob B to position 4.

4. To shut off the refrigerator turn the knob A to OFF

position.

IMPORTANCE OF LEVELLING A

REFRIGERATOR

In an absorption refrigerator system, ammonia is lique-

fied in the finned condenser coil at the top rear of the

refrigerator. The liquid ammonia then flows into the

evaporator (inside the freezer section) and is exposed

to a circulating flow of hydrogen gas, which causes the

ammonia to evaporate, creating a cold condition in the

freezer.

The tubing in the evaporator section is specifically sloped

to provide a continuous movement of liquid ammonia,

flowing downward by gravity through this section. If the

refrigerator is operated when it is not level and the vehi-

cle is not moving, liquid ammonia will accumulate in

sections of the evaporator tubing. This will slow the cir-

culation of hydrogen and ammonia gas, or in severe

cases, completely block it, resulting in a loss of cooling.

Any time the vehicle is parked for several hours with the

refrigerator operating, the vehicle should be levelled to

prevent this loss of cooling.

The vehicle needs to be levelled only so it is comfort-

able to live in (no noticeable sloping of floor or walls).

When the vehicle is moving, the levelling is not critical,

as the rolling and pitching movement of the vehicle will

pass to either side of level, keeping the liquid ammonia

from accumulating in the evaporator tubing.
