Warnings

-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. 
-Detectors are not suitable for areas classified as potentially explosive.

-Detectors 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 no alarm will be activated. If perimeter supervision is required, several sensors should be installed around that area.

Working conditions:

-Avoid handling refrigerant gases near the sensor. If this is unavoidable, use Set Hold or Maintenance mode. 
-Keep the detector work environment free of chemical agents (solvents, acetone vapours, paints, alcohol, cleaning products, silicone and derivatives, ethylene, etc.). 
-Avoid installing the detector near products or devices that might give off CO

. (

 only)

-Human breathing near the detector may increase the level of CO

. and generate false alarms. (

-Do not paint the detector or place it near solvents or paints. (

-The sensor should be installed away from: 

-Areas where fermentation and ripening processes of products (bread, pizza, fruit, etc.) may occur. (

 only)

 

-Smoke outlets located in confined spaces or from engines, generators or motorised machinery (fork-lift trucks, etc.).

 

-Particularly damp areas or with strong ventilation.

-The detector should usually be installed in an area where gas may concentrate, near to places where gas leaks could start.
-The detector’s location will depend on the refrigerant and will be in areas where gas leaks could concentrate. Taking into account individuals’ safety and their use of space, the lowest position of this space will 
be considered for refrigerants heavier than air (HCFC, HFC and CO

2

) and the highest possible position will be considered for refrigerants lighter than air (NH

3

).

Wiring

Always disconnect the power supply to do the wiring.
The wiring between the detector/transmitter and the station should 

NEVER

 be installed in a conduit together with power, control or supply cables. 

Cables for wiring the relay contact should have an adequate section depending on the unit to be connected.
Certain international standards maintain that the power supply of the alarm should originate from a different circuit to that used by the refrigeration and ventilation system. 

Please ensure that you 

comply with current local regulations.
