1.2 REGULATORY STANDARD
Wall-i CO2 devices are CE-marked and comply with European regulations:
European Low Voltage Directive (LVD) 2014/35/EU
European Electromagnetic Compatibility Directive (EMC) 2014/30/EU
1.3 NORMATIVE STANDARDS
•NF EN 61010-1 (2011). Safety requirements for electrical equipment for measurement, control
and laboratory use. Part 1: General requirements.
•EN 61326-1 (2013). Electrical equipment for measurement, control and laboratory use - EMC
requirements - Part 1: General requirements
•NF S 90351 (2013). Healthcare establishments - Clean rooms and associated controlled
environments. Requirements relating to the control of airborne contamination.
1.4 CLASSIFICATION
Type of protection against electric shocks
Class III
The unit operates on SELV (5Vcc).
Level of protection of applied parts against
electric shocks
No applied parts
Degree of protection against water and solids
IP 20
Operating mode
Continuous service
Operation under normal conditions of an unlimited duration without
exceeding operating temperature limits.
Level of safety when used in the presence of
flammable anaesthetics mixed with air,
oxygen or nitrous oxide
Device not suitable for use with flammable anaesthetics mixed with air,
oxygen or nitrous oxide.
Wall-i CO2is not an AP or APG category medical device. It must always be
kept more than 25 cm from the point where there is a mixture of flammable
anaesthetic with air, oxygen or nitrous oxide. The user is therefore
responsible for positioning Wall-i CO2accordingly in the room to be treated.
Electromagnetic interference
EN 61326-1 class B standard for conducted and radiated
disturbances.
Wall-i CO2is suitable for operation in an environment consisting of devices
which meet equivalent criteria.

1.6 FUNCTIONAL DESCRIPTION OF THE DEVICE
1.6.1 INTENDED USE
The Wall-i CO2 is a sensor that measures CO2concentration. It is used in buildings where air quality
needs to be controlled, such as schools, offices, meeting rooms and, as a result, gives an indication as
to the level of CO2 in the room where it is installed. It constitutes a health measure that supplements
protective measures.
1.6.2 OPERATING PRINCIPLES
The Wall-i CO2 is mounted to the wall or placed on a flat surface. CO2 molecules are collected and
counted, and the screen displays an indicative value in ppm (parts per million). The colour of the screen
(green, yellow, red) tells the user whether the CO2 concentration complies with “recommended”
thresholds.

SECTION 2 - INSTALLATION/USE
2.1 INSTALLATION
The Wall-i CO2is initially designed to be mounted to a wall. It can however be placed on a support
(shelf, cabinet, desk, etc.)
Wall bracket installation procedure: Screw fastening
The unit comes with a fixing kit including 2 nylon plugs for concrete, plaster or plasterboard walls and 2
screws.
▪Using a drill and a 5mm diameter concrete drill bit, drill two holes in the desired location, 50
millimetres apart. Or use the bracket as a template
▪Install the plugs using a hammer
▪Loosen the safety screw of the box supplied to secure the bracket to the wall.
▪Position the box bracket opposite the drilling holes and tighten the screws until they are flush
with the box.

.
Wall bracket installation procedure: Double-sided fastening.
▪Apply double-sided tape to the back of the bracket in order to fix it to the wall in the desired
location.
Once the wall bracket has been fastened,
▪Run the cable through the cut-out, and pull it out towards the inside of the bracket.
▪Connect the USB cable to the box and place the Wall-i CO2 on the cut-out of the bracket
provided for this purpose.
