Maintenance
Clean the surface of the alarm using a soft cloth, soap and water. Do not use abrasive detergents, petrol, alcohol or
solvents.
2.5.- Precautions
Using the equipment without following the manufacturer's instructions may affect the device's safety requirements.
To ensure that the device operates correctly, only probes supplied by AKO should be used.
The unit must be installed in a location protected from vibrations, water and corrosive gases, where the ambient
temperature does not exceed that shown in the technical data.
To get a correct reading, the probe must be situated in a location without any external heat influences except for
the temperature which is being measured or controlled.
The probe and its cable should NEVER be installed in the same conduit as power, control or supply cables.
The power supply circuit must be provided with a main switch rated at least 2 A, 230 V, located close to the equipment.
The cables will enter through the back and should be type H05VV-F or H05V-K. The gauge will depend on local regula-
tions, but should in no case be less than 1 mm².
The relay contact connecting cables should be 1 to 2.5 mm² and the common cable should always be 2.5 mm².
Halogen-free cables are recommended.
Between -40 ºC and +20 ºC, if the NTC probe is extended up to 1,000 m with minimum 0.5 mm² wire, the maximum
deviation will be 0.25 ºC (Wire for probe extension ref. AKO-15586).
