E2638-CO2

Rev 10.05.2021

Operating conditions

The device should be used both in a non-hazardous area and in a basic electromagnetic
environment, where the latter is defined in EN 61326-1. Avoid strong mechanical shock and
vibrations. Avoid corrosive atmosphere and areas highly contaminated with dust, oil mist,
etc. Keep the instrument away from direct sunlight. A sudden temperature or humidity
change might affect the sensitivity of the sensor.

Installation guidelines

Before proceeding with the installation it is mandatory to read the Safety requirements
section and make sure to comply with all listed instructions. Installation standards EN
60079-29-2 and EN 45544-4 are also recommended for further instructions and related
information about the installation. During the installation of the detector-transmitter the
following points must be considered:

Application (air quality control or leakage detection)

Properties of the space under investigation (room geometry, direction, and
velocity of airflows, etc.),

Since CO

2

is heavier than air, it is recommended to locate the sensor not higher

than the potential leakage. For air quality control place the sensor in the breathing
zone.

The device should be accessible for maintenance and repair.

The aforementioned conditions above will affect the coverage area of the device. however,
the coverage area for a transmitter is usually between 2.5 to 5 meters radius.

For early leakage detection install the sensor as close as possible to the potential leakage
sources (flanges, valves, pressure reducers, pumps, etc.), taking into consideration other
points listed above.

For general area monitoring without definite leakage sources, the detectors should be
distributed evenly in the room.

For personal safety control, the detectors are installed in the breathing zone (at the height
of the head of people or animals). The recommended sensor position is vertical, pointing
downwards.

For installing the device, attach the device to the wall using provided screws through the
side mounting holes or key slots (see mountains dimensions).
