Genuine Toshiba owner's manual. Couldn't really ask for more. And written in understandable English in contrast to a few recent experiences I have had with manuals for other equipment other than Toshiba but made in China and written in "Chinglish"!
I purchased a vintage Sony mixer off eBay and within the hour was able to locate and purchase the manual for it.I mean really,where else can you find a manual for a product made in 1983!? It was easy to find and purchase/download the manual I needed.I will use this site again for other equipment I have! Great site!
It`s full copy of a service manual from url http://www.philips.owner-manuals.com/PM3216-service-manual-PHILIPS.html

Defrosting
Defrosting the freezer compartment
During use and when the freezer compartment door is opened, moisture is deposited in the freezer compartment as frost. Remove this frost from time to time with the soft plastic scraper. Under no circumstances use hard or pointed objects to remove frost. The freezer compartment should always be defrosted when the layer of frost has reached a thickness of approx. 4 millimetres; however at least once a year. A good time for defrosting is when the appliance is empty or contains only a small amount of food. Warning! � Do not use electrical heating appliances or any other mechanical or artificial devices to speed up the defrosting process, with the exception of those recommended in these operating instructions. � Do not use defrosting sprays, they can be hazardous to your health and/or contain substances that damage plastics. Caution! Do not touch frozen food with wet hands. Your hands could stick to the food causing skin abrasions. 1. Remove frozen food, wrap it in several layers of newspaper and store it, covered, in a cool place. 2. Switch off the appliance and unplug it, or disconnect from the electricity supply. 3. Remove the stopper from the meltwater outlet and place a bowl underneath it to catch the meltwater. Tip: You can speed up the defrosting process by placing a pan with warm water in the freezer compartment and closing the doors. Remove pieces of ice that have fallen before they completely defrost. 4. After defrosting, thoroughly clean the freezer compartment ( see "Cleaning and Care" section).
