Site Preparation
Air Conditioning and Environmental Requirements
Air conditioning considerations include temperature, humidity, airborne dust, and exhaust venting. Each of these is considered in more detail in the following material.
Temperature, humidity, and altitude
The 5975 Series MSD is specified for operation under the following conditions:
•Operation requires constant temperature (variations <2 °C/h)
•Operation and storage require a noncondensing, noncorrosive atmosphere
•The temperature and humidity limits in Table 5
•Maximum altitude for operation: 2300 m (7500 ft)
Table 5 | Temperature and humidity limits |

| Temperature | Humidity (relative) |

Operation | 15 °C to 35 °C (59 °F to 95 °F) | 40% to 80% |
|
|
|
Storage | 0% to 95% | |
|
|

Environmental control systems must maintain these temperature and humidity ranges.
The MSD is rated for 1200 Watts (4000 BTU/h). The GC and the data system also contribute significantly to the cooling load although the exact amounts depend on their configurations. Additional allowances should be made for other heat sources such as heat from other equipment, heat from adjacent rooms, and heat from laboratory personnel.
