Preparing the Installation
Install the gas analyzer as close as possible to the sampling location.
Locate the gas preparation and calibration assemblies as close as possible to the
gas analyzer.
Provide for adequate natural air circulation around the gas analyzer. Avoid heat
buildup.
When installing several system housings in a 19-inch rack, maintain a minimum
spacing of 1 rack unit between housings.
The entire surface of the system housing is used to dissipate heat.
Protect the gas analyzer from:
• Cold
• Direct sunlight and heat
• Large temperature variations
• Strong air currents
• Accumulations of dust and dust infiltration
• Corrosive atmospheres
• Vibration (see "Vibrations", page 1-2)
