I purchased the unit from a private party and the original owners manual was not available. Having the ability to download it was extremely helpful and clarified operating the equipment immensely. This is a complicated unit and without the manual I would not have been able to maximize it's potential. Thank you.
Text excerpt from page 8 (click to view)
While in operation the -star compartment becomes progressively covered with frost. This frost, which acts as an insulator and thus prevents the cold from reaching the food should be removed whenever the thickness of the frost exceeds 1/4". To carry out complete defrosting proceed as follows: 1. Push the conveyor completely in. 2. Place a tray on the upper shelf of the refrigerator under the drain hole of the conveyor. 3. Remove any food from inside the -star compartment, wrap it in several sheets of newspaper and store in a cool dry place. 4. Push the button at the centre of the thermostat knob. To accelerate defrosting, place a bowl of hot water inside the compartment (with a piece of cardboard underneath the bowl as protection). 5. When defrosting is completed, dry thoroughly and remove the water collected in the tray. The refrigerator starts operating automatically following defrosting. After letting the appliance run for at least half an hour, replace the previously removed food into the -star compartment. When defrosting it is not necessary to remove the foods from the inner door and the refrigerator compartment. Important A temperature rise of the frozen food packs during defrosting may shorten their storage life. Never use sharp metal tools to scrape off frost from the evaporator as you could dam age it beyond repair.
