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.
6)No ignition sources
No person carrying out work in relation to a refrigerating 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.
7)Ventila
ted 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 refrigerating equipment
Where electrical components are being changed, they shall be fit for the purpose and to the
correct specifications. 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 operat
ing 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; and refrigerating 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 is absolutely
7. Sealed electrical components shall be replaced.
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 minimized. For repair to the refrigerating system, the following
precaution
s 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 minimize the risk of a flammable gas
or vapor 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 refrigerating 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
adjacent to the charging area.

10. Detection of flammable refrigerants
9. Cabling
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. 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 be
followed, since flammability is a consideration. The following procedure shall be adhered to:
-Safely remove refrigerant following local and national regulations;
-Evacuate;
-Purge the circuit with inert gas (optional for A2L);
-Evacuate (optional for A2L);
The refrigerant charge shall be recovered into the correct recovery cylinders if venting is not allowed by
local and national codes. For appliances containing flammable refrigerants, the system shall be purged
with oxygen-free nitrogen to render the appliance safe for flammable refrigerants. This process might
need to be repeated several times. Compressed air or oxygen shall not be used for purging refrigerant
systems.
For appliances containing flammable refrigerants, refrigerants purging shall be
achieved by breaking
the vacuum in the system with oxygen-free nitrogen and continuing to fill until the working pressure is
achieved, then venting to atmosphere, and finally pulling down to a vacuum (optional for A2L). This
process shall be repeated until no refrigerant is within the system (optional for A2L). When the final
oxygen-free nitrogen charge is used. the system shall be vented down to atmospheric pressure to
enable work to take place. The outlet for the vacuum pump shall not be close to any potential ignition
sources, and ventilation shall be available.
-continuously flush or purge with inert gas when using flame to open circuit;
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-c
alibration. (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.
Removal of refrigerant shall be according to Removal and evacuation.
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.
8. Intrinsically safe components must be replaced.
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.
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. Check
for 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.
12. 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 minimize the amount of refrigerant contained in them. Cylinders
shall be kept in an appropriate position according to the instructions. 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.
13. 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.
14. 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.
15. 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 the flammable
refrigerant. If in doubt, the manufacturer
should be consulted. 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.
The recovered refrigerant shall be processed according to local legislation 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 compressor body shall not be heated by an open flame or other
ignition sources to accelerate this process. When oil is drained from a system, it shall be carried out
safely.
Your air conditioner should be operated in an environment where
it is protected from immediate exposure to moisture (e.g. excess
condensation, splashed water, etc). Do not place or store your air
conditioner where it can fall or be pulled into water or any other
exposed liquid. If your unit becomes exposed to moisture, unplug
it immediately.
Always power the unit via the switch on the control panel.
