GAS and AC operation

LP gas operation

Before starting the refrigerator, check that all the manual gas valves are in the ON position. Do not forget the manual shutoff valve on the rear of the refrigerator.

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

2.Turn the thermostat knob B to position 4.

3.Press and hold button C and press 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”.

Note! After changing an LP tank, or after a long shut off pe- riod, 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

Whilst mobile:

-Do not operate the refrigerator on LP gas.

-Turn off the gas bottle.

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.

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.

REGULATING THE TEMPERATURE

The refrigerator is equipped with a thermostat that can be adjusted by turning the knob B to different setting to maintain the desired cabinet temperature.

Gas operation

•At “OFF, the thermostat closes its main valve and the burner runs continuously at the bypass rate, just enough to keep the burner lit.

•At “MAX”, the thermostat allows the burner to remain on high flame continuously.

AC operation (230-240 V AC)

•At “OFF, the contacts in the thermostat are open and the heating elements are off.

•At “MAX”, the heating element is “ON” continuously.

Lowest cabinet and freezer temperatures are obtained at this setting.

The thermostat can be adjusted between “MAX” and “OFF” to obtain the desired cabinet temperature. The closer the knob is to “MAX” - the colder the cabinet temperature. The closer the knob is to “OFF” - the warmer the cabinet temperature.

When the thermostat reaches the set temperature, it will cut the burner back to bypass or, in electric operation (230-

240 V AC), shut off the heating element. The setting of the thermostat is not critical, but we recommend it be adjusted to maintain a dry frost on the cooling fins. Adjust the ther- mostat knob closer to “MAX” when the outside temperature becomes warm.

Turning off the refrigerator

To shut off the refrigerator turn the knob A to “OFF”.

If the refrigerator will not be in operation for a period of weeks, it should be emptied, defrosted, cleaned and the door left ajar. The ice tray should also be dried and kept outside the cabinet.
