Using the Cleveland 21CET8 SteamCraft Ultra 3-Pan Electric Countertop Steamer is a breeze. First, make sure the water reservoir is filled to the appropriate level. You can use the automatic water-level controls to maintain the right amount of water. Place your food in the removable stainless steel racks and then put them into the steamer. Set the 60-minute electro - mechanical timer according to your cooking needs, or use the manual operation switch if you prefer. Turn on the ON/OFF power switch, and if you've used the standby mode, the generator will already be at the right temperature, so you can start cooking right away. When using the steamer, be careful with the hot steam when opening the two - piece door. Also, since it comes bare wire and must be hardwired, make sure to have a professional handle the wiring. For maintenance, regularly clean the cooking chamber, especially after heavy use. The coved corners make it easy to wipe clean. Use the deliming port to remove any limescale buildup from time to time. This will help keep the steamer running efficiently and extend its lifespan.
