If not please go to trouble shooting page 5. 8. Operating the freezer The empty freezer should be switched on for at least 5-6 hours prior to loading of the freezer. The freezer should not be loaded above the inside walls which is also the load line limit. Please note: After the lid has been opened, there will be a vacuum created inside the freezer due to the low temperatures. Wait a few minutes before trying to re-open the lid otherwise the handle could be damaged. 9. Defrosting 6. Electrical supply The electrical supply should always be in accordance with the rating plate on the back of the freezer. The supply must always be in accordance with the law and regulations regarding electrical safety. If any doubts, contact your supplier. In order for the freezer to work to its maximum efficiency the cabinet should be defrosted when a approx. 2mm thick ice layer has formed inside the cabinet. The ice layer is easily removed with a plastic or wooden scraper. Never use a sharp metal object which might will cause damage to the inner liner. The defrosting frequency is determined mainly by two factors the usage pattern (number of lid openings) and the relative humidity. Excess water can be drained out by using the drain water outlet on the front of the freezer. Fig. 1 7. Starting Up In case the compressor does not start when the freezer has been plugged in, the electrical supply may not be in order.
