3.0 INSTALLATION
This section describes installation of the following equipment:
Section 1.10 Detector (except SM425P-015)
Section 1.11 Detector (SM425P-015)
Section 1.12 Converter
Section 1.13 ZA8F Flow Setting Unit
Section 1.14 SM425CAL Automatic Calibration Unit
Section 1.15 Calibration Gas Unit Case (E7044KF)
3.1 Installation of the Detector
3.1.1 Location
Use the following precautions when installing the detector:
1. Allow easy and safe access to the detector for testing and maintenance work.
2. Ambient temperature must never exceed 150°C. The terminal box should not be installed close to
radiant heat.
3. A clean environment with no exposure to corrosive gases.
A natural convection type detector (SM425P----C), which uses ambient air as reference gas, requires the
ambient oxygen concentration be constant.
4. No vibration.
5. The measurement gas satisfies the specifications described in
Section 0.
6. No measured gas-pressure fluctuations.
3.1.2 Probe Insertion Port
Includes those analyzers equipped with a probe supporter and probe protector.
When preparing the probe insertion port, the following should be taken into consideration:
