2.7 Shipping pods
When fitted with its internal lithium batteries AQMesh pods are considered class
9 dangerous goods. It is therefore not possible to ship AQMesh pods via a normal
courier service, or travel with them on any commercial flight, unless you remove
the lithium battery pack first.
Note: The transportation of dangerous goods is controlled and governed
by a variety of different regulatory regimes, operating at both the
national and international levels. Collectively, these regulatory regimes
mandate the means by which dangerous goods are to be handled,
packaged, labelled and transported.
If you are sending pods fitted with lithium batteries to a new location they must
be packaged accordingly for class 9 dangerous goods and sent via a dangerous
goods carrier with all relevant paperwork and notifications.
You are able to ship AQMesh pods which are not fitted with lithium batteries via
any normal courier service.
2.8 Moving pods
When you have relocated your pods locally you must ensure they go through
rebasing in their new environment. This has to be manually selected via the
AQMesh server.
The risk of sensor failure is worst when pods are moved around / shipped. Please
ensure that RH / temp is changed gradually and the pods are handled gently,
particularly when they have been recently exposed to high RH%. For example,
when we bring pods indoors we leave them to sit in cool, dry conditions for 24
hours before taking them fully indoors.
2.9 Memory
Data is automatically transferred to the AQMesh server for secure storage and
processing. Data is only stored locally when it cannot be transmitted to the
server. The internal memory should not be used as a permanent storage
13
AQMesh Operating Manual
Important notices to all customers
OMAQM3.8
medium and any important data should be transferred to AQMesh.net as soon
as possible. The monitor should not be stored for prolonged periods with
valuable data in its memory. The pod memory should be cleared after any power
cycle to avoid potential corruption of its memory leading to loss of data.
2.10 Calibration
The gas sensors fitted into the AQMesh pods are fully calibrated during the
manufacturing process and they do not exhibit drift normally associated with
other types of gas sensor. However, to confirm accuracy prior to deployment
pods can be co-located with industry standard reference equipment and scaled
accordingly (please see user advice documents on AQMesh.com/support).
2.11 Cross-gas effects and data processing
The electrochemical sensors fitted into the AQMesh pod suffer cross-gas effects.
Measured gases (i.e. NO, NO2, O3) are compensated automatically during postprocessing on the AQMesh server. Any unmeasured gases could be the cause of
erroneous gas measurements.
Note: For further information please contact support@aqmesh.com or
contact your distributor.
2.12 Service
If handled and operated correctly your AQMesh pods will last for many years
but should go through regular maintenance to ensure correct operation and
accurate readings. The manufacturer recommends replacement of all sensors
and (if fitted) the internal lithium battery every 2 years. The optional particle
counter should be routinely serviced annually (more frequent service may be
required depending on local conditions).

Changing a sensor
Warning
Always ensure that you refer and comply with the relevant
National Working at Heights regulations prior to any
installation work.
You will be notified by email if any of the sensors in your AQMesh pod have
failed. Changing a sensor involves two steps. In addition to replacing the sensor
in the pod itself, the web-server needs updating to associate the relevant
calibration data (stored on the server) with the new sensor. Please follow the
steps below:-
Note: Important - DO NOT INSERT OR REMOVE THE GAS SENSORS WHILE
THE POWER IS ON AS IT CAN DAMAGE THE SENSORS.
On the AQMesh server:
Note: The server update must be done at the time the sensor is physically
changed in the pod or after, as changing the sensor serial number triggers
automatic re-basing.
1. Login to the AQMesh web application using you user ID and password
2. Select the correct AQMesh pod.
3. Please confirm the sensor has been changed using the link in your
notification email. Alternatively, enter the new sensor’s barcode in to the
field for the appropriate sensor type and confirm the update.

On the AQMesh pod:
4. Remove the six screws holding the sensor plate in position and remove
the plate.
5. Slide the power ON/OFF switch into the OFF position.
6. Locate and carefully remove the required sensor from its socket. It pulls
straight out but may require some gentle force.
7. Should any residue remain on the PCB, this should be cleaned.
8. Carefully insert the new sensor in position taking care not to damage the
sensitive gas interface membrane on its surface
9. Slide the ON/OFF switch into the ON position.

10.Ensure the status LED located behind the window in the AQMesh label
lights
11.Observe the LED sequence to determine the server connection is achieved
12. Replace the sensor plate and secure in position with its six screws
13.Check the web server is receiving data from the AQMesh pod (see
separate instructions)
14.The sensors in your AQMesh pod may take 2 days to stabilise within its
environment, followed by 2 to 4 days for base line adjustment
15.Failed sensors should be returned to your distributor or the manufacturer
as soon as possible.
Please note…Sensor failures are almost certainly caused by high ambient
RH% / low temperature and the sensors are most vulnerable during periods
of sustained high humidity. It is important that the pod is opened quickly as
the failed sensor can leak electrolyte and damage the PCB. We suggest you
use gloves to handle failed sensors as the electrolyte is a weak acid (only
equivalent to lemon juice).
The risk of failure is worst when pods are moved around / shipped. Please
ensure that RH / temp is changed gradually and the pods are handled gently,
particularly when they may have been exposed to high RH%. For example,
when we bring pods indoors we leave them to sit in cool, dry conditions for
24 hours before taking them fully indoors.
Please be aware that it is important that the sensor serial number is changed
on the server soon after the sensor is replaced so that the correct correction
figures are used by the algorithm and stabilisation / baselining is triggered
correctly.
All failed sensors are replaced under warranty in the first year.

3.12 Getting online
Each AQMesh pod is automatically registered on the AQMesh server when it is
manufactured. The pods are then assigned to a distributor who will in turn assign
them to the user and open an AQMesh online account for the user.
You should have received your username and password from your local
distributor with this shipment. If you have not received login details please
contact your local distributor.
Once your pod is activated log in to the AQMesh server.
Each pod can be selected and the setup and details can be viewed or changed
dependent on your access privileges. Data can also be viewed in tabular or
graphical formats.
You may amend your account details and change your password at any time.
You may also access additional technical assistance, download AQMesh
resources or renew or upgrade your account at any time at via the link on

3.17 Battery disposal considerations
Lithium-thionyl chloride batteries do not contain hazardous materials according
to EC directives 91/157/EEC, 93/86/EEC, and 2011/65/EU (RoHS directive). The
reaction products are inorganic and do not represent environmental hazards,
once the decomposition or neutralization process has terminated. The batteries
are free of mercury, lead, manganese, and cadmium.
NiMH batteries
EC battery directive 2006/66/EC has been implemented by most EC member
states.
According to the EU Battery Directive, batteries are marked with the symbol of
the crossed out wheeled bin (see figure above). The symbol reminds the end
user that batteries are not permitted to be disposed of with household waste,
but must be collected separately in accordance with applicable local regulations.
Do NOT incinerate.
Waste batteries must be effectively protected against short circuit during
storage and transportation.
