4-5 Installing the Detector
NOTE
To use the pyrolyzer unit (PLU-70), also refer to the individual operating manual.
<Detector Dimensions and Maintenance Space>
CAUTION
• Before installing the detector, remove the protective rubber caps from the GAS IN and GAS OUT
fittings. If the detector is turned on while the rubber caps are still in place, the pump and sensor may
be damaged. Do not forget to remove the caps.
Leave space for the crosshatched area when installing the detector.
The crosshatched space represents necessary maintenance space.
CAUTION
• Multiple detectors installed in the same location must be installed at least 5 mm apart. It is
recommended that they be 10mm apart.
• When you install more than one detector in the same location, install them in a rack or on a wall that
is not affected by vibrations.
When the detectors are installed side-by-side, if the rack or wall in which the detectors are installed
does not have enough strength, vibrations from the pumps inside the detectors can cause
resonance between them. In this case, take preventive actions like reinforcing the rack or wall.
