• Thank you for selecting this Gewiss product.
Gewiss products have been designed with attention to detail and built using only the
very best materials. Gewiss products will guarantee excellent and lasting performance.
• The installer is kindly requested to fill out this leaflet and then hand it to the end user,
asking that he/she carefully read it.
• Carefully read the instructions below as they provide important information on how the
gas detector works, how it should be fitted and serviced (routine and extraordinary
maintenance) and what to do with it once it reaches the end of its expected life.
• The manufacturer may not be held liable for injury to persons or pets or damage caused
by the use of the gas detector in situations and conditions other than those indicated in
the instructions below.
• The manufacturer may not be held liable in the case that the detector is sold in non-
original packaging. Immediately after removing the product from its packaging, make
sure that it is not damaged.
• Make sure that the main power supply has been switched off before attempting to fit
the device or touch the wiring.
• The gas detector will only work when plugged in to the mains. A device has a one minute
delay after a blackout or during installation, during which time its electronic components
are reset (see how it works - page 26).
• The sensor reaches full efficiency after 10 days from plugging in.
• Check that the detector is suitable for the type of gas it is expected to detect.
• Before connecting the detector, make sure that the data on its ratings plate match the
mains supply.
• Connect the detector as indicated in the drawings on page 23.
• Chorus products can be installed in environments which are dust-free and where no
special protection against the penetration of water is required.
They shall be installed in compliance with the requirements for household devices set
out by the national standards and rules applicable to low-voltage electrical installations
which are in force in the country where the products are installed, or, when there are
none, following the international standard for low-voltage electrical installations IEC
60364, or the European harmonization document HD 60364.
• Always contact an authorised technician or Gewiss's own customer service ("SAT" - see
page 82) if the detector is faulty and/or malfunctions and in the case of extraordinary
maintenance and scrapping.
