Refrigerating systems and heat pumps - Safety and environmental requirements - Part 4: Operation, maintenance, repair and recovery
The scope of EN 378-1:2007 is applicable.
This European Standard specifies requirements for safety and environmental aspects in relation to operation, maintenance, and repair of refrigerating systems and the recovery, reuse and disposal of all types of refrigerant, refrigerant oil, heat transfer medium, refrigerating system and part thereof.
These requirements are intended to minimise risks of injury to persons and damage to property and the environment resulting from improper handling of the refrigerants or from contaminants leading to system breakdown and resultant emission of the refrigerant.
Certain clauses and subclauses of this European Standard are not applicable to unit systems self contained systems and systems built on site which operate with charges of refrigerant up to 3 kg of refrigerant.
These subclauses are 4.1.1, 4.1.2, 4.2, 4.3, 5.1.1 to 5.1.4, 5.2, 5.3.1, 5.3.3 and 6.6.
For these systems, the necessary maintenance has to be described in the instruction manual and should
repairs be necessary, contact the nearest authorised repair service centre.
Kälteanlagen und Wärmepumpen - Sicherheitstechnische und umweltrelevante Anforderungen - Teil 4: Betrieb, Instandhaltung, Instandsetzung und Rückgewinnung
Es gilt der Anwendungsbereich von EN 378-1:2008.
Dieser Teil 4 der Europäischen Norm legt Anforderungen fest zu den sicherheitstechnischen und umwelt-relevanten Aspekten bei Betrieb, Instandhaltung und Instandsetzung von Kälteanlagen und bei der Rückgewinnung, Wiederverwendung und Entsorgung aller Arten von Kältemitteln, Kältemittelöl, Wärmeträgern, der Kälteanlage sowie Teilen der Kälteanlage.
Diese Anforderungen haben den Zweck, Verletzungsgefahren für Personen sowie Schäden an Sachen und der Umwelt zu minimieren, die sich aus unsachgemäßem Umgang mit Kältemitteln ergeben oder durch Verunreinigungen, die zu einem Ausfall der Anlage und nachfolgender Kältemittelemission führen.
Bestimmte Abschnitte und Unterabschnitte in diesem Teil 4 gelten nicht für betriebsfertige Kältesätze, Kältesätze und vor Ort errichtete Anlagen, die mit Kältemittel-Füllmengen bis zu 3 kg betrieben werden.
Dies sind die Unterabschnitte 4.1.1, 4.1.2, 4.3, 5.1.1 bis 5.1.4, 5.2, 5.3.1, 5.3.3 und 6.6.
Für diese Anlagen müssen die erforderlichen Instandhaltungsmaßnahmen im Bedienungs-Handbuch beschrieben werden und bei anfallenden Instandsetzungsarbeiten ist der nächstliegende zugelassene Wartungsdienst zu kontaktieren.
Systèmes de réfrigération et pompes à chaleur - Exigences de sécurité et d'environnement - Partie 4: Fonctionnement, maintenance, réparation et récupération
Le domaine d’application de l’EN 378-1:2008 est applicable.
La présente Norme européenne spécifie les exigences en matière de sécurité et d'environnement relatives au
fonctionnement, à la maintenance, à la réparation des systèmes de réfrigération et à la récupération,
réutilisation et mise au rebut de tous les types de fluides frigorigènes, d’huiles de systèmes de réfrigération,
de fluides caloporteurs, de systèmes de réfrigération et de parties de ceux-ci.
Ces exigences sont destinées à minimiser les risques de blessures aux personnes et de dommages aux
biens et à l'environnement résultant d'une mauvaise manutention des fluides frigorigènes ou de polluants
entraînant une panne du système et l'émission consécutive de fluide frigorigène.
Certains articles et paragraphes de la présente Norme européenne ne sont pas applicables aux systèmes
monoblocs et systèmes fabriqués sur le site qui fonctionnent avec une charge de fluide frigorigène inférieure
à 3 kg.
Ces paragraphes sont 4.1.1, 4.1.2, 4.2, 4.3, 5.1.1 à 5.1.4, 5.2, 5.3.1, 5.3.3 et 6.6.
Pour ces systèmes, les opérations de maintenance nécessaires doivent être décrites dans un manuel
d'instructions et, lorsque des réparations sont nécessaires, il convient de contacter le centre de réparation
habilité le plus proche.

instructed on the basis of the instruction manual about the construction, supervision, operation and mainte-nance of the refrigerating system, as well as the safety measures to be observed, if necessary the required personal protection equipment (see EN 378-3:2008, Annex A) and the properties and handling of the refriger-ant used. NOTE It is advisable that the operating personnel are present during evacuation, charging with refrigerant and
adjustment of the refrigerating system as well as, if possible, during assembly on site. 4.3 Documentation 4.3.1 The owner / operator shall keep an updated logbook of the refrigerating system if the refrigerant charge exceeds 3 kg. 4.3.2 In the logbook the following information shall be recorded: a) details of all maintenance and repair work; b) quantities and kind of (new, reused or recycled) refrigerant which have been charged on each occasion, and the quantities of refrigerant which have been transferred from the system on each occasion, see also 6.6; c) analysis of a reused refrigerant, if available, the results of which shall also be kept in the log-book; d) source of the reused refrigerant; e) changes and replacements of components of the system; f) results of all periodic routine tests; g) record of significant periods of non-use. 4.3.3 The log-book shall either be kept by the owner / operator and in the machinery room, or the data shall be stored in a computer with a printout in the machinery room, in which case the information shall be accessi-ble to the competent person when servicing or testing.
instruction manual, see EN 378-2. NOTE 1 The frequency of such maintenance depends on the type, size, age, use etc. of the system. In many cases more than one maintenance service is 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 user / owner concerned for the refrigerating system shall ensure that the system is inspected, regularly supervised and maintained in a satisfactory manner. 5.1.3 Systems with a charge larger than 3 kg should be subject to tightness inspection at least on an annual basis. If, during the inspection the suspicion of a leak exists, e.g. through refrigerant temperature checks or capacity reduction, then leak has to be located with suitable detection equipment and should be repaired and checked again after the repair in accordance with national regulations. The results of the inspection and measures taken afterwards should be included in the logbook. Refer to Annex D for detailed specification regarding in service inspection. 5.1.4 The parties concerned for the refrigerating system shall also be responsible when another person uses the refrigerating system, unless another division of responsibility has been agreed upon. 5.1.5 Regular maintenance which does not include interference with, nor adjustment of, the refrigerating system and which requires no specialised knowledge of refrigeration can be carried out by a person of appro-priate competence employed by the person responsible. Examples of such non-specialist maintenance include air-side cleaning of heat exchangers, cleaning of
condensate systems. 5.1.6 It is not permitted to charge a refrigerating system with a refrigerant type that does not comply with the machine card nor with the specifications of the manufacturer. In the case of appliances, the refrigerant type has to conform to the rating label data. In the case of retrofitting of an installation, see 5.4. 5.1.7 In the case of refrigerating systems located within an enclosure and considered as indirect systems under EN 378-1, no unauthorised persons shall remain in the occupancy during maintenance and
repair operations since the separation between refrigerant containing parts and occupants of the room is no more effective and leaks of refrigerant into the occupancy become possible. 5.1.8 Ensure that any marking to the compressor or equipment is replaced if any of the existing text has become un
