Carefully read the instructions and electronic connection diagrams in this document and follow them to the
letter. Keep this document in a safe place for future consultation.
The device must be installed by qualified technicians.
Installation guidelines
The detector
must
be installed (See also fig. 1, step 1):
Since Carbon Dioxide is heavier than air, it will be concentrated close to the floor. This device has a display
screen, so if it is positioned too low it would not be easy to use; we suggest installing it about 1.2-1.3m from
the floor.
The detector
must not
be installed (See also fig. 1, step 2):
•
exposed to direct sunlight or outdoors
•
near stoves and cooking appliances
•
near sinks and taps
•
near exhaust hoods, windows, fans etc.
•
in areas where dirt and/or dust can clog the bottom and side grille of the detector
•
where the temperature or humidity exceeds the detector's operating limits
•
in closed spaces (behind curtains, inside cupboards etc.).
Installation
Install the detector as follows (See also fig. 1, steps 3-6):
Use the tip of a screwdriver to lightly push down the side tabs of the detector until the wall mounting plate is
separated from the detector body
Fix the mounting plate to the wall with the screws supplied or a suitable wall bracket, or to the recessed
mounting cabinet used.
Connect the wiring on the wall mounting plate as shown in the connection diagram (Fig.2) in
Electrical
Installation
Remount the detector body onto the wall-mounting plate; make sure the tabs click into place.
