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.
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
The detector must be installed:
Methane Gas: since this gas is lighter than air, it will be con-
centrated close to the ceiling. Install it about two metres from
the gas device and about 30 cm from the ceiling.
For LPG (liquid gas in cylinders): since this gas is heavier
than air, it will be concentrated close to the floor. Install it about
two metres from the gas device and about 30 cm from the floor.
The detector must not be installed:
•
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 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.
on a 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 1) and, if necessary,
two side adapters need to be inserted to cover the side gap created when using some plates.
