Section 2.0
Cooling Requirement
Use Table 5-1 to assist in cooling requirements planning. Over half the cooling used by your
scanner is required for gantry operation. Locate a wall air-conditioning vent at floor level beside and
behind gantry to meet both gantry cooling needs and provide patient comfort. Do not locate any
cooling vents directly above the gantry. Air returns above the gantry are recommended.
Please refer to Figure 4-7, and Figure 4-12 in Chapter 4, Section 6.0, for component air flow
requirements.
