Using this Chef trim ring and socket is easy. First, make sure your stove is turned off and cooled down. Then, carefully remove the old trim ring and socket from the small hotplate. Place the new Chef 145mm trim ring and socket in position. It should fit nicely with its 162mm outer diameter and 140mm inner diameter. When it comes to maintenance, regularly clean the trim ring and socket with a soft, damp cloth to keep it looking good and functioning well. Avoid using harsh chemicals as they might damage the parts. If you notice any signs of wear or damage, it's a good idea to replace the parts to ensure your stove works safely and efficiently.
