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.),
●
Ammonia is lighter than air, so the sensor should be placed higher than the
potential leakage or formation source.
●
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 detector-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 detector-transmitters
should be distributed evenly in the room.
For personal safety control, the detector-transmitters are installed in the breathing zone (at
the height of the head of people or animals). The recommended sensor position is vertical,
pointing downwards.
Wall mount version
Attach the mounting lugs to the back of the detector-transmitter using the provided
screws. Screw the device to the wall through the mounting lug holes (for dimensions see
the drawing in the next section).
Duct mount version
Cut a hole with a diameter of 36...45 mm in the air duct at the chosen mounting place.
Place the rubber flange aligning the holes in the flange and the air-duct and fix the flange
with four self-tapping screws. Pass the sensor probe through the flange and adjust it to the
appropriate depth. Unscrew four lid screws and detach the lid from the
detector-transmitter.
