PRECHECK PRIOR TO SERVICE
[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, [General work area] to [Ventilated area] shall be completed prior to
conducting work on the system.
[Work procedure]
Work shall be undertaken under a controlled procedure so as to minimize the risk of a flammable gas or vapour being present
while the work is being performed.
[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.
[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 toxic or flammable atmospheres. Ensure that the leak detection equipment being used is suitable for use with all
applicable refrigerants, i.e. non-sparking, adequately sealed or intrinsically safe.
[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 CO 2 fire extinguisher adjacent to the charging area.
[No ignition sources]
No person carrying out work in relation to a refrigeration system which involves exposing any pipe work 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 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.

[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 actual refrigerant charge 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.
• When mechanical connectors are reused indoors, sealing parts shall be renewed. When flared joints are reused indoors,
the flare part shall be re-fabricated.
[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 no live electrical components and wiring are exposed while charging, recovering or purging the system;
• That there is continuity of earth bonding.
[Handling]
• The appliance should only be transported by two or more people holding the appliance securely.
• At delivery, the unit must be checked for damage. Any damage must be reported immediately to the carrier’s claims agent.
• The tubing shall be protected to the extent that it will not be handled or used for carrying during moving of the product.
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. 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 the apparatus is mounted securely.
- Ensure that seals or sealing materials have not degraded to the point 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 can inhibit the effectiveness of some types of leak detection equipment.
Intrinsically safe components do not have to be isolated prior to working on them.
REPAIRS 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.
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.

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.
LEAK DETECTION METHODS
The following leak detection methods are deemed acceptable for all refrigerant systems.
Electronic leak detectors may be used to detect refrigerant leaks but, in the case of flammable refrigerants, 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. For appliances containing flammable refrigerants,
oxygen free nitrogen (OFN) shall then be purged through the system both before and during the brazing process.
REMOVAL AND EVACUATION
When breaking into the refrigerant circuit to make repairs – or for any other purpose – conventional procedures shall be used.
However, for flammable refrigerants 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.
When breaking into the refrigerant circuit to make repairs – or for any other purpose – conventional procedures shall be used.
However, for flammable refrigerants it is important that best practice is followed since flammability is a consideration. The following
procedure shall be adhered to:
For appliances containing flammable refrigerants, 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 that ventilation is available.
CHARGING PROCEDURE
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 the appropriate purging gas. 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.

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. The treatment of the refrigerant, oil and other parts must comply with the applicable
legislation.
a) Become familiar with the equipment and its operation.
b) Isolate appliance 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 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.
LABELLING
Equipment shall be labelled stating that it has been de-commissioned and emptied of refrigerant. The label shall be dated and signed.
For appliances containing flammable refrigerants, ensure that there are labels on the equipment stating the equipment contains
flammable refrigerant.
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 all appropriate refrigerants including, when applicable, 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. 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.
