Ensure compliance with standards in force for electrical wiring. The devices must be connected to the mains
and remain permanently powered. Omnipolar disconnection must be included in the mains.
The installation of a detector must not be a substitute for the correct installation, use and maintenance of
combustible gas appliances and equipment and for ventilation and exhaust systems for fumes.
Carefully read the instructions and electrical wiring 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
Since carbon monoxide weighs the same as air, it will be concentrated near the same height as the appliance
that manifests combustion defects or that is located in premises with insufficient ventilation.
Install about 2 metres (minimum 1 metre, maximum 3 metres) from the gas-operated appliance and at
standard face height of the occupants in those premises; example: 130…...170cm in a kitchen, 50...…100cm
in a bedroom.
The detector must not be installed:
•
outdoors
•
too close to stoves, cooking appliances and, more in general, to gas appliances
•
near sinks and taps
•
near exhaust hoods, windows, fans etc.
•
in areas where dirt and/or dust can clog the front grille of the detector
•
where the temperature or humidity exceeds the detector's operating limits
•
in closed spaces (behind curtains, inside cupboards etc.).
depending on the model purchased, the detector can be mounted:
1. directly in type 503 recessed mounting box
2. screwed onto the wall with adapter ESN.KW
3. placing the device on a side table / shelf in the table-top version, using adapter ESN.KT/KC.
Before fixing the detector to box 503 or to adapter ESN.KW or ESN.KT/KC, the bracket needs to be adjusted to
the backing plate selected from major manufacturers of recessing equipment (see Table 2) and, if necessary,
two side adapters need to be inserted to cover the side gap created when using some plates.
After mounting is completed, fix the detector to box box 503 or to adapter ESN.KW or ESN.KT/KC and press
firmly on the front plate.
Make sure you fill in the detector replacement date on the self-adhesive label provided and stick it in a visible
position on the detector after installation.
