1 GENERAL INSTRUCTIONS
1.1 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 con-ducting work on the system.
1.2 Work procedure
Work shall be undertaken under a controlled procedure so as to minimise the risk of a flammable gas
or vapour being present while the work is being performed.
1.3 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.
1.4 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 tection
equipment being used is suitable for use with flammable refrigerants, i.e. nonsparking, adequately
sealed or intrinsically safe.
1.5 Presence of fire extinguisher
If any hot work is to be conducted on the refrigeration equipment or any associated parts, propriate
fire extinguishing equipment shall be available to hand. Have a dry powder or CO 2 fire extinguisher
adjacent to the charging area.
1.6 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 igarette
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.
1.7 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.
1.8 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
INSTRUCTIONS FOR REPAIRING APPLIANCES CONTAINING R290

6
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.
1.9 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.
2 REPAIRS TO SEALED COMPONENTS
2.1 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.
2.2 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.
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.
3 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.
4 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.
5 DETECTION OF FLAMMABLE REFRIGERANTS
Under no circumstances shall potential sources of ignition be used in the searching for or

7
detection of refrigerant leaks. A halide torch (or any other detector using a naked flame)
shall not be used.
6 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 recalibration. (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.
7 REMOVAL AND EVACUATION
When breaking into the refrigerant circuit to make repairs – or for any other purpose – con-
ventional 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 pipework are to take place.
Ensure that the outlet for the vacuum pump is not close to any ignition sources and there is
ventilation available.
8 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.
- 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.
9 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

8
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.
10 LABELLING
Equipment shall be labelled stating that it has been de-commissioned and emptied of refri-
gerant.The label shall be dated and signed.
Ensure that there are labels on the equipment stating the equipment contains flammable
refrigerant.
11 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 are
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

9
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. Only electric heating to the compressor body shall be employed to accelerate this
process.When oil is drained from a system,it shall be carried out safely.
Competence of service personnel
General
Special training additional to usual refrigerating equipment repair procedures is required when
equipment with flammable refrigerants is affected.
In many countries, this training is carried out by national training organisations that are accredited to
teach the relevant national competency standards that may be set in legislation.
The achieved competence should be documented by a certificate.
Training
The training should include the substance of the following:
Information about the explosion potential of flammable refrigerants to show that flammables may be
dangerous when handled without care.
Information about potential ignition sources, especially those that are not obvious, such as lighters,
light switches, vacuum cleaners, electric heaters.
Information about the different safety concepts:
Unventilated – (see Clause GG.2) Safety of the appliance does not depend on ventilation of
the housing. Switching off the appliance or opening of the housing has no significant effect on
the safety. Nevertheless, it is possible that leaking refrigerant may accumulate inside the
enclosure and flammable atmosphere will be released when the enclosure is opened.
Ventilated enclosure – (see Clause GG.4) Safety of the appliance depends on ventilation of
the housing. Switching off the appliance or opening of the enclosure has a significant effect
on the safety. Care should be taken to ensure a sufficient ventilation before.
Ventilated room – (see Clause GG.5) Safety of the appliance depends on the ventilation of
the room. Switching off the appliance or opening of the housing has no significant effect on
the safety. The ventilation of the room shall not be switched off during repair procedures.
