21、and, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. NOTE 1: This European Standard had also been proposed for inclusion in the mandate under the EU Directive 89/392/EEC (Machinery Directive). As the mand
22、ate has been given after the standard had been accepted by the Technical Committee for submission to formal vote and in order not to further delay its publication, it will be reviewed within the context of the latest version of the Machinery Directive directly after the publication. This EN 378-4 is
23、 part of a standard consisting of a series of the following parts: Part 1 Basic requirements, definitions, classification and selection criteria. Part 2 Design, construction, testing, marking and documentation. Part 3 Installation site and personal protection. Part 4 Operation, maintenance, repair a
24、nd recovery. For the 6-month enquiry, the draft standard was issued in 13 parts. After the discussion of the comments received during the enquiry it was decided to rearrange the content of 12 parts and to publish the final standard in the above 4 parts. The remaining Part 13 will be published as a s
25、eparate standard. Annex A of this European Standard is normative, the annexes B, C, D and ZA are informative.

Page 4 EN 378-4:2000 Introduction The introduction of EN 378-1 is applicable. Gases containing ch
30、lorine are damaging the ozone layer. These and other gases which are used as refrigerant also contribute to the global warming (greenhouse) effect. Other refrigerants such as ammonia, although not contributing to environmental damage, should be treated with caution due to their toxic or flammable na
31、ture. NOTE: Also see UNEP (United Nations Environment Program) Montreal Protocol on substances that deplete the ozone layer (latest revision) All parties concerned (e.g. designers, manufacturers, erectors, instructors, owners, users) should take advantage of any opportunity for reducing or eliminati
32、ng emissions of environmentally damaging refrigerants. The elimination of emissions should be one of the principal objectives during recovery, reuse and disposal of refrigerants. 1 Scope 1.1 The scope of EN 378-1 is applicable. 1.2 This Part 4 of the European Standard specifies requirements for safe
33、ty and environmental aspects in relation to operation, maintenance, repair of refrigerating systems and the recovery, reuse and disposal of all types of refrigerant. 1.3 These requirements are intended to minimize risks of injury to persons and damage to property and the environment resulting from i
34、mproper handling of the refrigerants or from contaminants leading to system breakdown and resultant emission of the refrigerant. 1.4 Certain clauses and sub-clauses of this Part 4 are not applicable to unit systems, self contained systems and systems built on site which operate with charges of refri
35、gerant up to: 2,5 kg of group L1 refrigerant; 1,5 kg of group L2 refrigerant; and 1,0 kg of group L3 refrigerant. This clause is: clause 5. 2 Normative references This European Standard incorporates, by dated or undated reference, provisions from other publications. These normative references are ci
36、ted at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references, the latest edit
37、ion of the publication referred to applies.

40、onal instructions 4.1 General 4.1.1 Care shall be taken to ensure that the personnel charged with the operation, supervision and maintenance of the refrigerating system are adequately instructed and are competent with respect to their tasks. The installer of the refrigerating system shall draw atten
41、tion to the necessity of adequate instruction of operating and supervision personnel. 4.1.2 Personnel in charge of the refrigerating system shall have knowledge and experience of the mode of functioning, operation and day-by-day monitoring of this system. 4.2 Instruction of operating personnel Befor
42、e a new refrigerating system is put into service, the person concerned shall ensure that the operating personnel are instructed on the basis of the instruction manual about the construction, supervision, operation and maintenance of the refrigerating system as well as the safety measures to be obser
43、ved and the properties and handling of the refrigerant used. NOTE: It is advisable that the operating personnel be present during evacuation, charging with refrigerant and adjustment of the refrigerating system as well as, if possible, during assembly on site. 5 Maintenance and repair 5.1 General 5.
44、1.1 Each refrigerating system shall be subjected to preventive maintenance in accordance with the instruction manual, see EN 378-2. NOTE 1: However, the frequency of such maintenance depends on the type, size, quality, age, use, etc. of the system. In many cases more than one maintenance service is
45、required in the course of one year in accordance with legal requirements. NOTE 2: For personal protective equipment against refrigerants see EN 378-3. 5.1.2 The parties concerned for the refrigerating system shall ensure that the system is inspected, regularly supervised and maintained in a satisfac
46、tory manner. 5.1.3 The parties concerned for the refrigerating system shall also be responsible when the refrigerating system is used by another person, unless another division of responsibility has been agreed upon. 5.1.4 Regular maintenance which does not include interference with, nor adjustment
47、of, the refrigerating system and which requires no specialized knowledge of refrigeration engineering can be carried out by a person of appropriate competence employed by the person responsible.
