4 INSTALLATION

4.1 LOCATION AND MOUNTING

Mount the AMC-2751 sensor/transmitter on a solid, non-vibrating surface or structure in an area
where the ambient concentration of gas is not directly affected by the presence of clean air
supply, ventilation systems, blockage by surrounding articles and
gases. Reading will be affected by presence of hydrogen gas, ethanol and nitrogen dioxide (500
ppm of hydrogen will cause 200 ppm CO reading, 2000 ppm of ethanol will cause less than 30
ppm CO reading, 30 ppm of nitrogen dioxide will cause less than 10 ppm CO reading). Please,
refer to local codes for further sensor/transmitter installation information.
The installer is required to provide any mounting hardware that may be required.
The AMC-2751 sensor/transmitter circuit board with sensor is removable from the enclosure for
ease of installation.
Important Notes:
Mount enclosure with the sensor located as per figure 2. This will ensure correct
orientation. Where possible it is recommended to turn off supply power before
removing or replacing the transmitter or sensor.
