System Power

The GPX4000LZ is turned on using the rocker switch on the left side of the unit. This switch powers up the
electronics enclosure, two exhaust fans, and the vacuum pump. Power is delivered to other system components
as well, but they will not turn on until other switches on the control panel are moved to the "ON" position.
