Chapter 2 - Site preparations 2 - 3
2-2-1-3 Cooling
The cooling requirement for the VIVID E9 / VIVID E7 scanner with monitor and on board peripherals, is
up to 3800 BTU/h. This figure does not include cooling needed for lights, people, or other equipment in
the room. Each person in the room places an additional 300 BTU/h demand on the cooling system.
2-2-1-4 Lighting
Bright light is needed for system installation, updates and repairs. However, operator and patient
comfort may be optimized if the room light is subdued and indirect. Therefore a combination lighting
system (dim/bright) is recommended. Keep in mind that lighting controls and dimmers can be a source
of EMI which could degrade image quality. These controls should be selected to minimize possible
interference.
