SERVICING INSTRUCTIONS
• The service manual is intended only for qualified personnel with
authorisation for handling flammable refrigerants.
1.1 Area check
Before starting work on asystem containing flammable refrigerants,
safety checks are necessary to ensure that the risk of ignition is
minimised. When repairing acooling system, the following measures
must be adhered to prior to performing any work.
1.2 Work procedure
Work must be performed following acontrolled procedure so that the risk
of flammable gases or fumes being present during this time is minimised.
1.3 General work area
The whole maintenance crew and other personnel at the site must be
informed about the nature of the works being performed. Work in tight
areas must be prevented. The area around the work site must be divided
into sections. It must be ensured that the conditions inside the area are
safe by means of inspections of flammable materials.
1.4 Check for presence of arefrigerant
The area must be checked using an appropriate detector for the presence
of refrigerant before and during work to ensure that technicians are aware
of apotentially flammable atmosphere. It must be ensured that the
device used for the detection of leaks is suitable for use on flammable
refrigerants, i.e. non-sparking, appropriately sealed or intrinsically safe.
1.5 Presence of afire extinguisher
In the event that any work is performed on the cooling device or
associated parts under heat, then asuitable fire extinguisher must be on
hand. In the vicinity of the filling area, there must be apowder or CO2fire
extinguisher.
1.6 No ignition sources
No person performing work related to the cooling system that
encompasses the uncovering of any pipes that contain or have contained
flammable gasses may use any ignition sources in amanner that could
lead to afire or explosion hazard. All possible ignition sources, including
the smoking of cigarettes should be kept at asufficient distance from the
installation, repair, removal or disposal location, during which flammable
refrigerant could potentially be released into the surrounding environment.
Prior to starting work, the area around the appliance must be checked to
ensure that there are no fire hazards or ignition risks present. A"smoking
forbidden" sign must be installed.
1.7 Ventilated area
It must be ensured that the area is ventilated or appropriately ventilated
prior to penetrating the system or performing any work under heat.
The intensity of ventilation must continue for the time that works are
performed. Ventilation should safely dissipate any released refrigerant
and draw it out into the atmosphere as apriority.
1.8 Cooling system checks
In places where electrical components are replaced, these components
must be suitable for this purpose and conform to correct specifications.
The manufacturer'sinstructions for maintenance and service must always
be followed. If any doubts arise, it is necessary to request help from the
manufacturer'stechnical department.
• On installations containing flammable refrigerants, it is necessary to
perform the following checks:
– the amount of refrigerant corresponds to the size of the room in which
components containing refrigerant are installed;
– ventilation systems and outlets are in full working order and are not
clogged;
– if any indirect cooling circuit is used, the second circuit must be
checked for the presence of refrigerant;
– the markings on the appliance must remain constantly visible and
legible, and marking and signs that are illegible must be repaired;
– The cooling pipes and components are installed in locations where it
is not probable that they will be exposed to any substances that could
corrode the parts containing refrigerant, unless these components are
built using materials that are inherently resistant to corrosion or are
appropriately protected against corrosion.
1.9 Electrical device check
The repair and maintenance of electrical components must include safety
checks and inspections of components.
In the event of amalfunction that could affect safety, no electrical power
may be connected to the circuit until the malfunction is satisfactorily
resolved. In the event that the malfunction cannot be immediately
repaired but it is necessary to continue running the appliance, an
appropriate temporary solution must be used. The owner of the appliance
must be informed in such away that all parties know about it.
The initial safety check must ensure:
• that capacitors are discharged: this must be performed in asafe way
to prevent the possibility of sparking;
• that no electrical components or wiring is uncovered during the
process of filling, draining or cleaning the system;
• that the grounding is not interrupted.
2. Repair of sealed components
When repairing sealed components, all the electrical power supply must
be disconnected from the appliance on which work is being performed
before sealed lids, etc. are removed. When it is absolutely necessary
to have live power supply going into the appliance while servicing the
appliance, it is necessary to install apermanent device in the most critical
point to detect leakage so that adangerous situation is averted.
Special attention must be paid to ensuring that as aresult of the work
performed on electrical components the cover is not changed to
the extent of affecting the level of protection. This must also include
damage to cables, excessive number of connections and terminals not
performed according to original specifications, damaged gaskets, incorrect
configuration of plugs, etc.
It is necessary to ensure that the appliance is mounted safely.
It is necessary to ensure that gaskets or sealing materials are not
damaged in such away that they no longer serve to prevent the
entry of aflammable atmosphere. Spare parts must conform to the
manufacturer'sspecifications.
Note:
The use of silicone gaskets and seals may suppress
the efficiency of certain type of leak detection devices.
Intrinsically safe components do not need to be
disconnected prior to being worked on.
3. Repairs of intrinsically safe components
No permanently inductive or capacitative load may be placed on the
circuit without it being ensured that thereby the permitted voltage and
current for the used appliance is not exceeded.
Intrinsically safe components are the only type on which it is possible to
work in aflammable environment even while under live current. Testing
equipment must have correct specifications.
Parts are replaced using only parts specified by the manufacturer.
Different parts could result in ignition of refrigerant upon leakage into the
environment.
4. Cabling
Check that cabling is not exposed to wear and tear, corrosion, excessive
pressure, vibrations, sharp edges or any other negative environmental
effects. This check must also take into consideration the effects of ageing
and permanent vibrations from sources such as compressors or fans.
5. Detection of flammable refrigerants
Under no circumstances may potential sources of ignition be used for
locating or detecting refrigerant leaks.
Ahalogen burner (or any other type of detector utilising an open flame)
must not be used.
6.Leak detection methods
The following leak detection methods are considered acceptable for
systems containing flammable refrigerants.
For the detection of flammable refrigerants, electronic leak detectors
must be used, however their sensitivity may not be appropriate or they
may require recalibration. (Detection equipment must be calibrated in
an area without any refrigerant present). It is important to ensure that
the detector is not apotential ignition source and that it is suitable for
the used refrigerant. The leak detector must be set to apercentage of
LFL refrigerant and must be calibrated for the used refrigerant and the
respective gas percentage is confirmed (maximum 25 %).

- 13 - 12/2022
2022, .
Leak detection liquids are suitable for use on most refrigerants, however,
detergents containing chlorine must be excluded since chlorine may react
with the refrigerant and corrode copper pipes.
In the event of asuspected leak, all open flames must be removed/
extinguished.
In the event that the refrigerant leak is found and requires hard soldering,
then all the refrigerant must be drained from the system or separated (by
closing avalve) in apart of the system distant from the leak. The system
must then be cleaned out using oxygen-free nitrogen (OFN) both before
as well as after the hard soldering process.
7. Collection and pump discharge
In the event that the cooling circuit is breached due to repairs – or for
any other reason – conventional procedures must be followed. It is,
however, important to adhere to the best method due to flammability. It is
necessary to adhere to the following procedure:
• collect the refrigerant;
• clean out the circuit using inert gas;
• pump out;
• again clean out using inert gas;
• open the circuit by cutting or hard soldering.
The contents of the circuit must be collected into correct collection
cylinders. The system must be "flooded" with OFN (oxygen-free nitrogen)
for the unit to remain safe. It may be necessary to repeat the procedure
several times. For this task, neither compressed air nor oxygen may be
used.
Flooding may be achieved by disrupting the vacuum in the system with
the use of OFN, and by continued filling until the operating pressure
is achieved, then venting into the atmosphere and finally lowering to
avacuum. This process must be repeated if refrigerant still remains in
the system. When the last OFN cartridge is used, the system must be
ventilated to atmospheric pressure to enable work to be performed. This
activity is absolutely necessary if hard soldering is to be performed on
the pipes.
It is necessary to ensure that the vacuum pump outlets are not nearby to
any ignition source, and ventilation must be provided.
8.Filling procedure
Apart from conventional filling procedures, also the following
requirements must be adhered to.
– It is necessary to ensure that no contamination by various refrigerants
occurs when the filling device is used. Hoses or pipes must be as short
as possible to minimise the amount of refrigerant contained inside of
them.
– Cylinders must be held vertically.
– It is important to ensure that the cooling system is grounded prior to
being filled with refrigerant.
– When filling is complete, the system must be marked with alabel (if it
does not have one already).
– It is necessary to pay extreme care to ensure that the cooling system
is not overfilled.
Apressure test using OFN must be performed before refilling the system.
In the case of aleak, the system must be tested after being refilled but
also before being put into operation. Averification test must be performed
before leaving the installation location.
9.Taking out of operation
Prior to performing this procedure it is essential that the technician fully
acquaints him/herself with the device and all its particulars. Correct
practice of safely collecting all refrigerant is recommended. Prior to
performing this activity, oil and refrigerant samples must be taken if an
analysis is required prior to using the using the regenerated refrigerant for
the first time. It is essential that prior to starting this activity that electricity
is available.
a) Acquainting one'sself with the device and its activity.
b) Electrical disconnection of the system.
c) Prior to starting the procedure, ensure that:
• if required, mechanical device for handling the cylinder with refrigerant
is available;
• all personal protective devices are available and used correctly;
• the collection process is constantly under the supervision of
acompetent person;
• the collection device and cylinders comply with respective norms.
d) Pump out the cooling system if possible.
e) If achieving vacuum is not possible, collection pipes are created to
enable the collection of refrigerant from various parts of the system.
f) Ensure that the cylinder is placed on the scale before the collection
of refrigerant is started.
g) The collection device is turned on and runs according to the
manufacturer'sinstructions.
h) Cylinders are not overfilled. (No more than 80 % of liquid content
capacity).
i) The maximum operating pressure of the cylinder is not exceeded,
even temporarily.
j) When the cylinders are properly filled up and the procedure is
complete, ensure that the cylinders and devices are immediately
removed from the installation location and that all the separation
valves on the device are closed.
k) The collected refrigerant must not be filled into adifferent cooling
system until it is cleaned and checked.
10. Marking with alabel
• The appliance must be marked with alabel indicating that it has been
put out of operation and is without refrigerant. The label must be
dated and signed. It is ensured that there are labels on the appliance
indicating that it contains flammable refrigerant.
11. Collection
When the refrigerant is collected from the system, either due to servicing
or when it is put out of operation, it is recommended to adhere to proper
practice and safely collect all the refrigerant.
When the refrigerant is transferred into the cylinders, it is necessary to
ensure that appropriate cylinders for collecting refrigerant are used.
It is necessary to ensure that there is asufficient number of cylinders
available to contain the complete contents of the system. All the cylinders
that are to be used must be intended for collecting refrigerant and be
marked with alabel for this refrigerant (i.e. special cylinders for collecting
refrigerant). The cylinders must be complete with asafety valve and
associated closing valves in good working condition. The empty collection
cylinders are pumped empty and if possible cooled prior to collecting
refrigerant.
The collection device must be in good operating condition with aset of
manuals relating to the device, which are on hand and it must be suitable
for collecting flammable refrigerants. Apart from this, aset of calibrated
scales in good operating condition must also be available. Hoses must
be complete with couplers without seepage and in good condition. Prior
to using the collection device, check that it is in satisfactory operating
condition, has been properly maintained and all the associated electrical
components are sealed to prevent ignition in the event of refrigerant being
released. If in any doubt, consult the manufacturer.
The collected refrigerant must be returned to the refrigerant supplier in
the correct collection cylinder and with arespectively arranged waste
transport letter. Refrigerants are not to be mixed in the collection units and
especially not in the cylinders.
In the event that compressors or compressor oils are to be collected,
ensure that they are pumped out to an acceptable level in order to
ensure that flammable refrigerant does not remain in the lubricant. The
pump discharge process must be performed before the compressor is
returned to the supplier. To speed up this process, only electrically heated
compressor elements may be used. When the oil is drained from the
system, it must be disposed of safely.
