be stored in the frozen food storage compartment. They can then be stored about three times as long as in the fresh food storage compartment. To prevent drying out, keep food in covered dishes, in plastic bags or wrapped in aluminum foil.

CAUTION

Do not store explosive substances in the re- frigerator, such as cigarette lighter gas, petrol, ether or the like.

Ice Making

Ice cubes can be made in the ice trays which should be filled with water to within l/4" (5 nun) from the top. To release the ice cubes seize the tray with both hands and twist the tray. Cubes not required should preferably be replaced in the tray. Refill the tray with water and replace the tray on the freezer shelf.

Ice making is accelerated if the thermostat knob is turned to setting "MAX". It is a good idea to do this a few hours before an anti- cipated need for ice but be sure to turn the knob back to normal setting when the ice is formed or the foodstuffs in the cabinet may become frozen hard.

Defrosting

Some refrigerator models are equipped with an automatic defrosting device incorporated with the cooling unit. This device 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. 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 re- filled 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 de- frosting device should be defrosted regularly' by turning off the refrigerator. Empty the re- frigerator 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.

To Shut Down the Refrigerator

To shut down the refrigerator temporarily set the thermostat to off and turn off the gas tap. If the cabinet is not in operation over a period

of weeks, it should be emptied and cleaned and the door left ajar. The ice trays should also be dried and kept outside the cabinet.

Cleaning

To clean the interior lining of the refrigerator use lukewarm weak soda solution. The evaporator, ice trays and shelves must, however, be cleaned with warm water only. Never use strong chemicals or abrasives to clean these parts or the pro- tective surface will be spoiled. It is important always to keep the refrigerator clean.

Periodic maintenance

NOTE: Before working on the refrigerator, make sure that 110 V A. C. and optional 12 VD.C. leads are disconnected.

Once or twice a year depending on use, it is necessary to clean and adjust the burner assembly. Proceed as follows:

2.Disconnect lighter cable from the electrode.

3.Loosen burner fixing screw and withdraw burner.

4.Clean burner tube with a brush. Blow with compressed air.

5.Screw off jet and clean with alcohol. Blow with compressed air. Never use a needle or similar.

6.Clean flue baffle and flue.

7.Clean the cooling unit and the floor under the refrigerator.

8.Reassemble.

9.The entire gas installation should be checked for leaks. Test all pipe connections with soapy water, not with an open flame.
