    Generator standby 10K

    I did not recieve a Generac brand generator what I recieved was a Centurian brand generator and after found out that what was shipped is the Lowes brand of Generator made by generac but for sales at Lowes. I haven't installed it yet. Awaiting permits from the Town. Also when I opened the Box once it was recieved there was no user/owners manual. I was able to get a copy from Factory Pure. As for shipping the freight company scheduled 3 times to deliver the generator because it hadn't been recieved at their dock prior to them making contact with me for delivery. Also they could only give me a window of 4-6 hours for delivery. As a Salesman this was a problem being off the road for that length of time 3 days only to find out that the generator was not even at the dock of the transport company. Ultimately on the third day I was able to schedule a late delivery after having to speak directly to a supervisor. We will see how it works once it is installed
