6.Information on servicing
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.
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.
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.
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.
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)No ignition sources
No person carrying out work in relation to a refrigeration system which involves exposing any

7
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.
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.
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.
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 isabsolutely
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)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.
7.Repairs to sealed components
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.

8
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.Ahalide 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 LFLof 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.
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.

9
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
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.
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.
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.

10
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 contains 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. 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.
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.
