    8 MAINTENANCE SAFETY WARNINGS FOR OPERATIONS ON UNITS CONTAINING R1234ze 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 41 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 42 8 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.
  • Page 43 MAINTENANCE Before attempting the procedure, check that: The mechanical manipulation equipment is available, if necessary, to handle refrigerant tanks; All the personal protection equipment is available and employed correctly; The recovery procedure is monitored at all times by skilled personnel; The recovery equipment and tanks comply with suitable standards.
  • Page 44 MAINTENANCE 4 Storage of equipment/devices The equipment must be stored in compliance with the instructions provided by the manufacturer. 5 Storing packed (unsold) equipment Packing must be performed in such a way that mechanical damage to the equipment inside it does not cause refrigerant leaks.
  • Page 45 MAINTENANCE General Maintenance must be performed by authorized centres or by qualified personnel The maintenance allows to: maintaining the unit efficient reduce the deterioration speed all the equipment is subject to over time collect information and data to understand the efficiency state of the unit and prevent possible faults WARNING Before checking, please verify the following:...

  • Page 47 MAINTENANCE Unit booklet Foresee a unit schedule to keep trace of the interventions made on the unit. In this way, it will be easier to adequately schedule the various interventions and facilitate any troubleshooting. On the schedule note: date intervention description carried out measures etc.
  • Page 48 MAINTENANCE Compressor casing heater Check: closure Operation water side heat exchanger The exchanger must to be able to provide the maximum thermal exchange, therefore it is essential for the inner surfaces to be clean of dirt and build-up. 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 49 MAINTENANCE Air coil Accidental contact with the exchanger fins can cause cuts: wear protective gloves. The coil must allow maximum thermal exchange, therefore, the surface must be clear from dirt and scaling. It is recommended a quarterly cleaning of the coils, as the minimum.
  • Page 50 MAINTENANCE Electric fans Check: the fans and the relative protection gridsare well fixed the fan bearings (evident by noise and anomalous vibrations) the terminal protection covers are closed and the cable holders are properly positioned. Screw compressors - Periodical checks Compressor supply line shut-off valve Do not remove the seal Remove only if authorized by the manufacturer.

  • Page 57 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 situa- tions 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 58 RESIDUAL RISKS Do not remain in the vicinity of the safety valve and never leave the refri- ger-ating system taps closed. Electric parts An incomplete attachment line to the electric network or with incorrectly sized cables and/or unsuitable protective devices can cause electric shocks, intoxication, damage to the unit or fires.
