The only other thing I would mention, is to be sure to have a large diameter input hose feeding the unit from the spigot. And one that's as short as possible. This will assure your pump is being fed a high enough volume of water.
Stay away from these small I.D. "Bionic Steel" hoses you see in infomercials on TV. Some of them only have a 3/16" to 1/4" I.D. They're great for watering the Marigolds, but they can easily starve a high capacity pressure pump of water. And there is no faster way to screw up a good pressure washer.
