6.Information on servicing
6-1 Checks to the area
Prior to beginning work on systems containing
flammable refrigerants, safety checks are
necessary to ensure that the risk of ignition is
minimised. For repair to the refrigerating
system, the following precautions shall be
complied with prior to conducting work on the
system.
6-2 Work procedure
Work shall be undertaken under a controlled
procedure so as to minimise the risk of
flammable gas or vapour being present while
the work is being performed.
Precautions for using R32 refrigerant
The basic installation work procedures are the
same as the conventional refrigerant(R22 or
R410A). However, pay attention to the following
points:

6-3 General work area
All maintenance staff and others working in the
local area shall be instructed
on the nature of work being carried out. Work
in confined spaces shall be avoided.
The area around the workspace shall be
sectioned off. Ensure that the conditions
within the area have been made safe by
control of flammable material.
6-4 Checking for presence of refrigerant
The area shall be checked with an appropriate
refrigerant detector prior to and during work,
to ensure the technician is aware of
potentially flammable atmospheres.
Ensure that the leak detection equipment
being used is suitable for use with flammable
refrigerants, i.e. non-sparking, adequately
sealed or intrinsically safe.
6-5 Presence of fire extinguisher
If any hot work is to be conducted on the
refrigeration equipment or any associated
parts, appropriate fire extinguishing equipment
shall be available to hand.
Have a dry powder or CO2 fire extinguisher
adjacent to the charging area.
6-6 No ignition sources
No person carrying out work in relation to a
refrigeration system which
involves exposing any pipe work that contains
or has contained flammable refrigerant shall
use any sources of ignition in such a manner
that it may lead to the risk of fire or explosion
All possible ignition sources, including
cigarette smoking, should be kept sufficiently
far away from the site of installation, repairing,
removing and disposal, during which
flammable refrigerant can possibly be released
to the surrounding space.
Prior to work taking place, the area around the
equipment is to be surveyed to
make sure that there are no flammable hazards
or ignition risks. “No Smoking” signs shall be
displayed.
6-7 Ventilated area
Ensure that the area is in the open or that it is
adequately ventilated before breaking into the
system or conducting any hot work.
A degree of ventilation shall continue during
the period that the work is carried out.
The ventilation should safely disperse any
released refrigerant and preferably expel it
externally into the atmosphere
.
6-8 Checks to the refrigeration equipment
Where electrical components are being
changed, they shall be fit for the purpose and
to the correct specification.
At all times the manufacturer's maintenance
and service guidelines shall be followed. If in
doubt consult the manufacturer's technical
department for assistance
The following checks shall be applied to
installations using flammable refrigerants:
–The charge size is in accordance with the
room size within which the refrigerant
containing parts are installed;
–The ventilation machinery and outlets are
operating adequately and are not obstructed;
–If an indirect refrigerating circuit is being
used, the secondary circuit shall be checked
for the presence of refrigerant;
–Marking to the equipment continues to be
visible and legible. Markings and signs that
are illegible shall be corrected;
–Refrigeration pipe or components are
installed in a position where they are unlikely
to be exposed to any substance which may
corrode refrigerant containing components,
unless the components are constructed of
materials which are inherently resistant to
being corroded or are suitably protected
against being so corroded.
6-9 Checks to electrical devices
Repair and maintenance to electrical
components shall include initial safety checks
and component inspection procedures.
If a fault exists that could compromise safety,
then no electrical supply shall be connected to
the circuit until it is satisfactorily dealt with.
If the fault cannot be corrected immediately
but it is necessary to continue operation, an
adequate temporary solution shall be used.
This shall be reported to the owner of the
equipment so all parties are advised.
Initial safety checks shall include:
–That capacitors are discharged: this shall be
done in a safe manner to avoid possibility of
sparking;
–That there no live electrical components and
wiring are exposed while charging,
recovering or purging the system;
–That there is continuity of earth bonding
7. Repairs to sealed components
During repairs to sealed components, all
electrical supplies shall be disconnected from
the equipment being worked upon prior to any
removal of sealed covers, etc.
If it is absolutely necessary to have an
electrical supply to equipment during
servicing, then a permanently operating form
of leak detection shall be located at the most
critical point to warn of a potentially hazardous
situation.
Particular attention shall be paid to the
following to ensure that by working on
electrical components, the casing is not
altered in such a way that the level of
protection is affected.
3

This shall include damage to cables,
excessive number of connections, terminals
not made to original specification, damage to
seals, incorrect fitting of glands, etc.
Ensure that apparatus is mounted securely.
Ensure that seals or sealing materials have not
degraded such that they no longer serve the
purpose of preventing the ingress of flammable
atmospheres.
Replacement parts shall be in accordance with
the manufacturer's specifications.
NOTE:
The use of silicon sealant may inhibit the
effectiveness of some types of leak detection
equipment. Intrinsically safe components do
not have to be isolated prior to working on them.
8.Repair to intrinsically safe components
Do not apply any permanent inductive or
capacitance loads to the circuit without
ensuring that this will not exceed the
permissible voltage and current permitted for
the equipment in use.
Intrinsically safe components are the only
types that can be worked on while live in the
presence of a flammable atmosphere. The test
apparatus shall be at the correct rating.
Replace components only with parts specified
by the manufacturer. Other parts may result in
the ignition of refrigerant in the atmosphere
from a leak.
9.Cabling
Check that cabling will not be subject to wear,
corrosion, excessive pressure, vibration,
sharp edges or any other adverse
environmental effects.
The check shall also take into account the
effects of aging or continual vibration from
sources such as compressors or fans
10.Detection of flammable refrigerants
Under no circumstances shall potential
sources of ignition be used in the searching for
or detection of refrigerant leaks.
A halide torch (or any other detector using a
naked flame) shall not be used
11.Leak detection methods
The following leak detection methods are
deemed acceptable for systems containing
flammable refrigerants:
–Electronic leak detectors shall be used to
detect flammable refrigerants, but the
sensitivity may not be adequate, or may need
re-calibration. (Detection equipment shall be
calibrated in a refrigerant-free area.)
–Ensure that the detector is not a potential
source of ignition and is suitable for the
refrigerant used.
–Leak detection equipment shall be set at a
percentage of the LFL of the refrigerant and
shall be calibrated to the refrigerant employed
and the appropriate percentage of gas (25 %
maximum) is confirmed.
–Leak detection fluids are suitable for use with
most refrigerants but the use of detergents
containing chlorine shall be avoided as the
chlorine may react with the refrigerant and
corrode the copper pipe-work.
–If a leak is suspected, all naked flames shall
be removed/ extinguished.
–If a leakage of refrigerant is found which
requires brazing, all of the refrigerant shall be
recovered from the system, or isolated (by
means of shut off valves) in a part of the
system remote from the leak.
–Oxygen free nitrogen (OFN) shall then be
purged through the system both before and
during the brazing process.
12.Removal and evacuation
When breaking into the refrigerant circuit to
make repairs – or for any other purpose –
conventional procedures shall be used.
However, it is important that best practice is
followed since flammability is a consideration.
The following procedure shall be adhered to:
–Remove refrigerant;
–Purge the circuit with inert gas;
–Evacuate;
–Purge again with inert gas;
–Open the circuit by cutting or brazing.
The refrigerant charge shall be recovered into
the correct recovery cylinders.
The system shall be “flushed” with OFN to
render the unit safe.
This process may need to be repeated several
times.
Compressed air or oxygen shall not be used
for this task.
Flushing shall be achieved by breaking the
vacuum in the system with OFN and continuing
to fill until the working pressure is achieved,
then venting to atmosphere, and finally pulling
down to a vacuum.
This process shall be repeated until no
refrigerant is within the system. When the final
OFN charge is used, the system shall be
vented down to atmospheric pressure to
enable work to take place.
This operation is absolutely vital if brazing
operations on the pipe-work are to take place.
Ensure that the outlet for the vacuum pump is
not close to any ignition sources and there is
ventilation available.
13.Charging procedures
In addition to conventional charging
procedures, the following requirements shall
be followed:
–Ensure that contamination of different
refrigerants does not occur when using
charging equipment.
–Hoses or lines shall be as short as possible to
minimise the amount of refrigerant contained
in them.
4

–Cylinders shall be kept upright.
–Ensure that the refrigeration system is earthed
prior to charging the system with refrigerant.
–Label the system when charging is complete
(if not already).
–Extreme care shall be taken not to overfill the
refrigeration system.
Prior to recharging the system it shall be
pressure tested with OFN.
The system shall be leak tested on completion
of charging but prior to commissioning.
A follow up leak test shall be carried out prior
to leaving the site.
14.Decommissioning
Before carrying out this procedure, it is
essential that the technician is completely
familiar with the equipment and all its detail.
It is recommended good practice that all
refrigerants are recovered safely.
Prior to the task being carried out, an oil and
refrigerant sample shall be taken in case
analysis is required prior to re-use of
reclaimed refrigerant. It is essential that
electrical power is available before the task is
commenced.
a) Become familiar with the equipment and its
operation.
b) Isolate system electrically.
c) Before attempting the procedure ensure
that:
–Mechanical handling equipment is available,
if required, for handling refrigerant cylinders;
–All personal protective equipment is available
and being used correctly;
–The recovery process is supervised at all
times by a competent person;
–Recovery equipment and cylinders conform to
the appropriate standards.
d) Pump down refrigerant system, if possible.
e) If a vacuum is not possible, make a manifold
so that refrigerant can be
removed from various parts of the system.
f) Make sure that cylinder is situated on the
scales before recovery takes
place.
g) Start the recovery machine and operate in
accordance with manufacturer's instructions.
h) Do not overfill cylinders. (No more than
80 % volume liquid charge).
I ) Do not exceed the maximum working
pressure of the cylinder, even temporarily.
j ) When the cylinders have been filled
correctly and the process completed, make
sure that the cylinders and the equipment
are removed from site promptly and all
isolation valves on the equipment are
closed off.
k) Recovered refrigerant shall not be charged
into another refrigeration system unless it
has been cleaned and checked.
15.Labelling
Equipment shall be labelled stating that it has
been de-commissioned and emptied of
refrigerant.
The label shall be dated and signed.
Ensure that there are labels on the equipment
stating the equipment contain flammable
refrigerant.
16.Recovery
When removing refrigerant from a system,
either for servicing or decommissioning, it is
recommended good practice that all
refrigerants are removed safely.
When transferring refrigerant into cylinders,
ensure that only appropriate refrigerant
recovery cylinders are employed.
Ensure that the correct number of cylinders
for holding the total system charge is available
All cylinders to be used are designated for the
recovered refrigerant and labelled for that
refrigerant (i.e. special cylinders for the
recovery of refrigerant).
Cylinders shall be complete with pressure
relief valve and associated shut-off valves in
good working order.
Empty recovery cylinders are evacuated and,
if possible, cooled before recovery occurs.
The recovery equipment shall be in good
working order with a set of instructions
concerning the equipment that is at hand and
shall be suitable for the recovery of
flammable refrigerants.
In addition, a set of calibrated weighing scales
shall be available and in good working order.
Hoses shall be complete with leak-free
disconnect couplings and in good condition.
Before using the recovery machine, check
that it is in satisfactory working order, has
been properly maintained and that any
associated electrical components are sealed
to prevent ignition in the event of a refrigerant
release.
Consult manufacturer if in doubt.
The recovered refrigerant shall be returned to
the refrigerant supplier in the correct recovery
cylinder, and the relevant Waste Transfer
Note arranged.
Do not mix refrigerants in recovery units and
especially not in cylinders.
If compressors or compressor oils are to be
removed, ensure that they have been
evacuated to an acceptable level to make
certain that flammable refrigerant does not
remain within the lubricant.
The evacuation process shall be carried out
prior to returning the compressor to the
suppliers.

6-1 Vérifications de la zone
6-2 Procédure de travail
Les travaux doivent suivre la procédure règlementée
en vigueur, de façon à réduire les risques
d'évaporation des gaz/vapeurs inflammables présents
pendant les opérations.
Précautions liées à l'utilisation de liquide frigorigène R32
Les procédures de base d’installation sont les mêmes que
celles du réfrigérant conventionnel (R22 ou R410A).
Cependant, faites attention aux points suivants:
Conformité avec les Règlementations locales
Conformité avec les Règlementations nationales.
Avant de commencer à travailler sur un appareil
contenant un liquide frigorigène inflammable, quelques
contrôles de sécurité sont nécessaires, afin de s'assurer
que le risque d'inflammation est diminué. Pour toute
réparation du système frigorigène, les précautions
suivantes doivent être prises.

6-3 Zone de travail
L'ensemble des équipes de travail doit être informé du
type d'opérations menés à bien sur le site. Le travail dans
des zones confinées doit être évité.
Les opérations en cours autour de l'espace de travail
doivent être mises en pause. Vérifiez que l'ensemble des
conditions nécessaires à la sécurité du lieu de travail ont
été bien respectées.
6-4 Contrôle de la présence ou de l'absence de
liquide frigorigène
La zone de travail doit être équipée d'un détecteur de
fumées adapté avant le début des travaux, afin de
garantir la sécurisation de l'espace de travail.
Vérifiez que le système de détection utilisé est adapté
à une utilisation dans une atmosphère contenant des
substances inflammables (ex: système hermétique,
scellé ou intrinsèquement sûr).
6-5 Présence d'un extincteur
Dans le cas où des travaux impliquant des opérations
de chauffe seraient impliqués, la zone de travail doit être
munie d'un extincteur adapté
Un extincteur à poudre sèche ou CO2 doit être installé
dans la zone de travail.
6-6 Aucune source d'inflammation
Aucune personne chargée d'effectuer des travaux
sur un système de réfrigération impliquant un risque
d'explosion (ou contenant du liquide frigorigène) n'est
autorisée à utiliser des sources d'inflammation; car
cela pourrait entraîner un risque d'incendie ou
d'explosion.
Toute source d'inflammation possible, y compris les
allume-cigares, doit être tenue à l'écart du site
d'installation, de réparation, de retrait d'élimination,
dès qu'une fuite de liquide frigorigène est possible.
Avant de commencer les travaux, la zone de travail
doit être contrôlée, afin de s'assurer qu'aucune
source d'inflammation n'est présente. Des panneaux
« Interdiction de fumer » doivent être en place.
6-7 Zone ventilée
Vérifiez que la zone est correctement ventilée avant
de procéder à des opérations de chauffe.
Un niveau de ventilation suffisant doit être assuré
pendant les opérations.
La ventilation doit permettre la dissipation du liquide
de réfrigération et doit, de préférence, permettre son
évacuation vers l'extérieur.
Lorsque vous remplacez des composants électriques,
ces derniers doivent être installés conformément aux
caractéristiques indiquées.
Les consignes de maintenance et de réparation
doivent toujours être observées. Encas de doute,
contacter l'Assistance Technique du fabricant.
Les vérifications suivantes doivent être effectuées sur
les modèles contenant du liquide frigorigène:
6-8 Contrôle de l'équipement de réfrigération
–La taille de la charge est conforme à la taille de la
pièce dans laquelle les pièces contenant le
réfrigérant sont installées;
Les appareils de ventilation et les sorties
fonctionnent correctement et ne sont pas
obstrués;
Dans le cas où un circuit frigorigène indirect serait
utilisé, le circuit secondaire devra être vérifié afin
de s'assurer de la présence de liquide frigorigène;
Le marquage sur l'équipement reste visible et
lisible. Les marques et signes illisibles doivent
être corrigés;
Les conduites ou les tuyaux de réfrigération sont
installés de façon à n'être exposés à aucune
substance susceptible de corroder les
composants contenant le liquide frigorigène, sauf
dans le cas où ces composants seraient
constitués de matériaux protégés/résistants à de
telles substances.

6-9 Vérifications des appareils électriques
Les opérations de maintenance et de réparation
apportées aux composants électriques doivent
inclure des contrôles de sécurité de base ainsi que
des procédures d'inspection spécifiques aux
composants.
Si une erreur est constatée, susceptible de mettre en
danger l'utilisateur, alors le circuit ne doit pas être
alimenté en électricité jusqu'à résolution de la panne.
Dans le cas où le problème ne pourrait pas être résolu
dans l'immédiat, mais que l'appareil doivent continuer
de fonctionner, une solution temporaire devra être
mise en place.
Ce problème devra être signalé au propriétaire de
l'équipement, de façon à ce que les différentes parties
en soient informées.
Les contrôles de sécurité de base incluent les
vérifications suivantes:
–Que les condensateurs soient déchargés: Cette
opération doit avoir lieu de manière sécurisée, afin
d'éviter les risques d'étincelles;
–Existe-t-il des composants électriques et/ou des
câbles exposés pendant les opérations
d'approvisionnement en liquide, de réparation ou de
vidange;
–Qu'il y a continuité de la liaison à la terre.
7. Réparation des composants scellés
Pendant les opérations de réparation et avant le
retrait des caches des composants hermétiques,
l'ensemble des dispositifs électriques doit être
déconnecté de l'appareil en cours de réparation.
Il est absolument nécessaire de disposer d'une
alimentation électrique pendant les opérations de
dépannage, ainsi que d'un système de détection des
fuites, dès qu'un risque de situation dangereuse
existe.
Une attention particulière doit être accordée aux
éléments suivants pour garantir qu'en travaillant sur
les composants électriques, le boîtier ne soit pas
modifié de manière à affecter le niveau de protection.
3

Cela comprend la vérification des câbles, des
raccords, des bornes, embouts d'étanchéité, etc. Il
convient de vérifier qu'ils ne sont pas endommagés.
Vérifiez que l'appareil est assemblé de manière
sécurisée.
Vérifiez que les joints et autres composants
hermétiques n'ont pas été endommagés, de façon à
ce qu'ils soient toujours en mesure de protéger
l'appareil d'une éventuelle inflammation.
Les pièces de rechange doivent être utilisées selon
les exigences du fabricant.
REMARQUE:
L'utilisation de joint silicone peut annuler l'efficacité de
certains systèmes de détection des fuites.
Il n'est pas nécessaire d'isoler les composants de
sécurité avant d'intervenir dessus.
8. Réparation des composants intrinsèquement sûrs
N'appliquez pas trop de charge sur le circuit et
respectez toujours le degré de tension maximum
recommandé par le fabricant.
Les composants intrinsèquement sûrs sont les seuls
capables de fonctionner dans une atmosphère
inflammable. L'appareil de test doit être contrôlé,
ainsi que ses paramètres électriques.
Ne remplacez les composants qu'au moyen de
pièces détachées recommandées par le fabricant.
Les autres éléments pourraient prendre feu dans
une atmosphère similaire.
9. Câblage
Vérifiez que les câbles ne sont pas: endommagés,
corrodés / ne sont pas soumis à des vibrations,
pressions excessives / ne sont pas exposés à des
objets pointus ouautres dangers.
Ces vérifications doivent également prendre en
considération les effets de l'usure naturelle sur
certains éléments tels que les compresseurs ou les
ventilateurs.
10. Détection de réfrigérants inflammables
En aucun cas une source d'inflammation ne devra
être utilisée pour détecter les fuites de liquide
frigorigène.
Vous ne devez en aucun cas utiliser de flambeau
(ou autre détecteur muni d'une flamme nue).
11. Méthodes à suivre pour détecter les fuites
Les méthodes suivantes de détection des fuites
sont considérées comme acceptables pour les
systèmes contenant des liquides frigorigènes
inflammables:
–Les détecteurs de fuite électroniques doivent être
utilisés pour détecter es liquides frigorigènes
inflammables, mais la sensibilité peut ne peut
être adaptée, ou peut avoir besoin d'être calibrée
de nouveau. (L'équipement de détection doit être
calibré dans une zone ne contenant pas de
liquide frigorigène).
–Vérifiez que le détecteur n'est pas une source
potentielle d'inflammation et convient au liquide
frigorigène utilisé.
–L'équipement de détection des fuites doit être réglé
sur un pourcentage de la LFL du réfrigérant et doit
être étalonné sur le réfrigérant utilisé et le
pourcentage approprié de gaz (25% maximum) est
confirmé.
–Les liquides de détection de fuites sont adaptés à la
plupart des types de liquides frigorigènes mais
l'utilisation de détergents contenant du chlore doit être
évitée dans la mesure où le chlore peut réagir avec le
liquide frigorigène et corroder les conduites en cuivre.
–Si vous suspectez une fuite, toutes les flammes nues
doivent être éliminées.
–Si une fuite de liquide frigorigène nécessitait une
opération de brasure, l'ensemble du liquide devra être
isolé (au moyen de vannes d'extinction).
–L'oxygène sans nitrogène (OFN) doit être évacué du
système avant et pendant le processus de brasure.
12. Retrait et évacuation
Lorsque vous intervenez sur le circuit frigorigène afin
de le réparer- ou pour toute autre raison suivez les
procédures traditionnelles recommandées.
Toutefois, il est important que les Bonnes Pratiques
soient respectées, dans la mesure où le risque
d'inflammation doit être prise en considération.
La procédure suivante doit être observée:
–Retirez le liquide frigorigène;
–Vidangez le circuit au moyen de gaz inerte;
–Évacuez le système;
–Vidangez de nouveau au moyen de gaz inerte;
–Ouvrez le circuit en le découpant ou par brasure.
Le liquide frigorigène déversé dans le circuit doit
pouvoir rejoindre les cylindres.
Pendant le « rinçage » du système, ce dernier doit
être hors tension (OFF) afin de sécuriser les
opérations.
Ils e peut que ce processus doive être répété à
plusieurs reprises.
Cette opération ne peut pas se faire au moyen d'air
comprimé ni d'oxygène.
Le rinçage doit être réalisé en brisant le vide dans le
système avec OFN et en continuant à remplir jusqu'à
ce que la pression de travail soit atteinte, puis en
évacuant vers l'atmosphère et en tirant finalement
vers le vide.
Ce processus doit être répété jusqu'à ce qu'il n'y ait
plus de réfrigérant dans le système. Lorsque la
charge OFN finale est utilisée, le système doit être
purgé jusqu'à la pression atmosphérique pour
permettre le travail.
Ce processus est absolument déterminant si des
opérations de brasure doivent avoir lieu.
Assurez-vous que la sortie de la pompe à vide n'est
proche d'aucune source d'inflammation et qu'une
ventilation est disponible.
13. Procédures d'approvisionnement
En plus des procédures d'approvisionnement
traditionnelles, les exigences suivantes doivent être
respectées:
–Assurez-vous que les différents liquides
frigorigènes ne sont pas contaminés pendant
l'opération.
–Les embouts et conduites doivent être aussi
courts que possibles afin de réduire le volume de
liquide contenu à l'intérieur.
