Before performing any reparation operations on the cooling system, comply with the following warnings.
  • Page 118 11 MAINTENANCE containing refrigerant, unless they are manufactured with material intrinsically resistant to corrosion or suitably protected against corrosion. Electrical device checks The reparation and maintenance of electric components must include initial safety checks and component inspection procedures. In case of a fault that compromises safety, do not perform any electrical connection to the circuit until said fault is suitably resolved.
  • Page 119 11 MAINTENANCE Check that the detector is not a possible source of ignition and that it is suitable for the refrigerant. Leak detection equipment must always be set to an LFL percentage and calibrated depending on the refrigerant used, so the correct gas percentage (25% max) must be verified. Leak detection fluids are suitable for most refrigerants, although using detergents containing chlorine should be avoided as this substance may react with the refrigerant and corrode copper pipes.
