One of the advantages of the 7, 10, 12, and 15KW automatic Home Generator Systems is that they are designed to run once a week for twenty minutes. All you have to do is program it when you want this task to be performed and it will start up automatically. During this time it will not only lubricate the engine, but it will also run a diagnostics check. If there are any problems with this process, an LED display located inside the front access panel will alert you.
