*AKO guarantees alarm activation from a cooling gas concentration of 7000 PPM. The alarm may
activate at lower concentrations depending on the type of gas used.
NOTE: If the pre-alarm function is activated, it will activate on detecting approximately half of the
concentration necessary for activating the alarm.

WARNINGS

-Sensors supervise a point and not an area. If the gas leak does not reach the sensor, or
the level of concentration in that point does not reach the foreseen values according to
the type of gas (see table) no alarm will be activated.
-The alarm and detectors should be installed in a place protected from vibrations, water and corrosive
gases, where the ambient temperature does not exceed the value indicated in the technical data. The
station should be installed in a place where the regular presence of people who can alert to the
presence of alarms is guaranteed.
-Neither the alarm or gas detector are suitable for areas classified as potentially explosive.
Work conditions:
-Keep the detector work environment free of chemical agents (solvent, paints, alcohol, cleaning
products, silicone and derivatives, ethylene, etc.).
-Avoid handling refrigerant gases near the detector.
-Do not paint the detector or place it near solvents or paints.
-The detector should be installed away from:
Areas where fermentation and ripening processes of products (bread, pizza, fruit, etc.) may occur.
Ÿ
Smoke outlets located in confined spaces or from engines, generators or motorised machinery (fork-
Ÿ
lift trucks, etc.).
Particularly damp areas or with strong ventilation.
