SERVICE 10.01.2003 / Page 2 MAX 18/AW Whirlpool Europe Doc. No: 4812 714 14499 8538 018 99261 Customer Service Introduction safety INTRODUCTION Before leaving the factory each oven is carefully checked. It must, however, be installed and used correctly. Despite all the steps taken to make the oven safe, the safety is dependent on the correct installation and the fact the user understands how to use and maintain the oven. The information in this section should be used as a reminder that the oven is safe and that anyone who uses it must first read the instructions for use in order to be able to use the oven correctly and obtain best results. SAFETY To avoid injury to yourself and damage to the appliance always work to the following rules when servicing an oven. Always disconnect the plug from the mains before starting work. If there is no plug switch off the electric supply at the control box. When you have finished servicing an oven before you reconnect it to the mains, make sure that: - all the internal connections are correct - the wires are insulated and not touching the door or the cabinet or anything sharp - all the earth connections are electrically and mechanically sound - do not modify or anyway interfere with the safety devices built-in to the oven - make sure that each replacement part you use conforms to the manufacturer´s specifications Do not start a repair if you have any doubt as to your ability to complete it. CAUTION - MICROWAVE RADIATION PERSONNEL SHOULD NOT BE EXPOSED TO THE MICROWAVE ENERGY WHICH MAY RADIATE FROM THE MAGNETRON, WAVEGUIDE OR ANTENNA IF THEY ARE IMPROPERLY USED OR CONNECTED. ALL INPUT AND OUTPUT MICROWAVE CONNECTIONS, WAVEGUIDES, FLANGES AND GASKETS MUST BE SECURE. NEVER OPERATE THE DEVICE WITHOUT A MICROWAVE ENERGY ABSORBING LOAD ATTACHED. NEVER LOOK INTO AN OPEN WAVEGUIDE OR ANTENNA WHILE THE DEVICE IS ENERGIZED. NEVER OPERATE AN OVEN WITH CABINET OFF WITHOUT MEASURING THE MICROWAVE LEAKAGE AROUND MAGNETRON AND VISIBLE MICROWAVE CONNECTIONS (WELDING JOINTS). Do not operate the oven if the following conditions exist: - the door does not close firmly against the door support because of the door being warped or the hinges damaged. - The door trims or seals are damaged. - If there is any visible damage to the oven. - if the door does not close properly. Avoid operating the oven if known components in the interlock system, oven door or microwave generating assembly are known defective. They must be replaced. WARNING - HIGH VOLTAGE IT IS POSSIBLE TO COME IN CONTACT WITH LETHAL HIGH VOLTAGE WHEN WORKING WITH HV TRANSFORMER, HV CAPACITOR AND MAGNETRON. THEREFORE NEVER TRY TO MEASURE THE HIGH VOLTAGE. ALWAYS TAKE UTMOST CARE WHEN PERFORMING ELECTRIC MEASUREMENTS INSIDE THE OVEN. Downloaded from www.Manualslib.com manuals search engine
