System Requirements
API 4000 Site Planning Guide
10
Operating Environment
The site environment should be kept clean and generally dust-free. High standards of
cleanliness are expected. The instrument should be located in an area that is:
•
Free of smoke and corrosive fumes
•
Not prone to excessive vibration
•
Out of direct sunlight
•
Away from radiators
Mass Spectrometer
This instrument complies with Pollution Degree 2; Installation Category 2, Electrical
Insulation requirements. To ensure the proper operating conditions for the instrument, the
environmental conditions must be maintained within ±2 °C in the range of 15 °C and
30 °C (59 °F to 86 °F) with a relative humidity between 20 and 80% noncondensing.
An air conditioning unit with a capacity of 2550W (8700 Btu/h) is required for this API
system including the mass spectrometer, roughing pump(s), and the heat load from the
TurboIonSpray or Nebulizer heater.
Operation of the instrument above 2000 m (6500 ft) above sea level is not recommended.
Roughing Pump(s)
To ensure proper operation of the roughing pump(s), the ambient temperature must be
maintained between 15 °C and 30 °C (59 °F to 86 °F), with a relative humidity of 20 to
80% noncondensing.
NOTE:
It is important that the roughing pump(s) not be put in an enclosed area. Without
proper ventilation, it will fail prematurely or shut down from overheating, and cause
severe damage to the instrument.
