  • Page 48: Maintenance

    10 MAINTENANCE SAFETY WARNINGS FOR OPERATIONS ON UNITS CONTAINING R32 Area checks Before working on systems containing flammable refrigerants, perform safety checks to reduce the risk of combustion to the minimum. Before performing any reparation operations on the cooling system, comply with the following warnings.
  • Page 49 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 50 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. If a leak is suspected, all open flames must be removed or switched off. If a leak is identified that requires brazing, all the refrigerant must be recovered from the system or isolated (using interception valves) in a section of the system far away from the leak.
  • Page 51 The recovery equipment and tanks comply with suitable standards.  If possible, pump the cooling system.  If it is not possible to obtain a vacuum, make sure that a collector removes the refrigerant from various  parts of the system. Before proceeding with the recovery, check that the tank is located on the scales.

Periodically check the difference between the temperature of the supply water and the condensation temperature: if the difference is greater than 8°C–10°C it is advisable to clean the exchanger.

  • Page 60: Residual Risks

    12 RESIDUAL RISKS General In this section the most common situations are indicated,as these cannot be controlled by the manufacturer and could be a source of risk situations for people or things. Danger zone This is an area in which only an authorised operator may work. The danger zone is the area inside the unit which is accessible only with the deliberate removal of protections or parts thereof.
  • Page 61 If there is a fire the temperature of the refrigerant could reach values that in-crease the pressure to beyond the safety valve with the consequent possible projection of the refrigerant itself or explosion of the circuit parts that remain isolated by the closure of the tap. Do not remain in the vicinity of the safety valve and never leave the refriger-ating system taps closed.
