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 t for the purpose and
to the correct specication. 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 ammable 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 should be corrected.
• Refrigeration pipe or components are installed in a position where they are unlikely

10. 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 a ected.
This shall include damage to cables, excessive number of connections, terminals not made
to original speci cation, damage to seals, incorrect  tting of glands, etc.
• Ensure that seals or sealing materials have not degraded such that they no longer serve
the purpose of preventing the ingress of  ammable atmospheres. Replacement parts should
be in accordance with the manufacturer’s speci cations.
11. 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  ammable atmosphere. The test apparatus shall be at the correct rating.
• Replace components only with parts speci ed by the manufacturer. Other parts may result
in the ignition of refrigerant in the atmosphere from a leak.
12. Cabling
• Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp
edges or any other adverse environmental e ects. The check shall also take into account the
e ects of aging or continual vibration from sources such as compressors or fans.
13. Detection of  ammable refrigerants
• Under no circumstances, should 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  ame)
should not be used.
Note
The use of silicon sealant may inhibit the e ectiveness of some types of leak detection equipment. Intrinsically
safe components do not have to be isolated prior to working on them.
WARNING
(For using R290/R32 refrigerant only)

IMPORTANT SAFETY INSTRUCTIONS CONTINUED
11
14. Leak detection methods
• The following leak detection methods are deemed acceptable for systems containing ammable
refrigerants. Electronic leak detectors shall be used to detect ammable refrigerants, but the
sensitivity may not be adequate, or may need re-calibration. (Detection equipment should
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 should 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 conrmed.
• Leak detection uids 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 pipework.
• If a leak is suspected, all naked ames should be removed/ extinguished. If a leakage
of refrigerant is found which requires brazing, all of the refrigerant should be recovered from the
system, or isolated (by means of shut o valves) in a part of the system remote from the leak.
Oxygen free nitrogen (OFN) should then be purged through the system both before and during
the brazing process.
15. 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
ammability is a consideration. Opening of the refrigeration systems should not be done
by brazing.
• 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 should be recovered into the correct recovery cylinders. The system
should be ushed 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 should be achieved by breaking the vacuum in the system with OFN and continuing
to ll until the working pressure is achieved, then venting to atmosphere, and nally pulling down
to a vacuum. This process shall be repeated until no refrigerant is within the system.
• When the nal 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.
WARNING
(For using R290/R32 refrigerant only)

16. Charging procedures
• In addition to conventional charging procedures, the following requirements should be followed.
Ensure that contamination of dierent refrigerants does not occur when using charging
equipment. Hoses or lines should be as short as possible to minimize the amount of refrigerant
contained in them.
• Cylinders should 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 should be taken not to overll the refrigeration system.
• Prior to recharging the system, it should be pressure tested with OFN. The system should
be leak tested on completion of charging but prior to commissioning. A follow up leak test
should be carried out prior to leaving the site.
17. 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 should 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.
• Become familiar with the equipment and its operation.
• Isolate the system electrically.
• Before attempting the procedure ensure that:
• When breaking into the refrigerant circuit to make repairs or for any other purpose,
conventional procedures should be used.
• Mechanical handling equipment is available, if required, for handling refrigerant cylinders.
• 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.
• Pump down refrigerant system, if possible.
• If a vacuum is not possible, make a manifold so that refrigerant can be removed from
various parts of the system.
• Make sure that cylinder is situated on the scales before recovery takes place.
• Start the recovery machine and operate in accordance with manufacturer’s instructions.
Do not overll cylinders. (No more than 80 % volume liquid charge).
• Do not exceed the maximum working pressure of the cylinder, even temporarily.
• When the cylinders have been lled correctly and the process is completed, make sure that
the cylinders and the equipment are removed from the site promptly and all isolation valves
on the equipment are closed o.
• Recovered refrigerant should not be charged into another refrigeration system unless
it has been cleaned and checked.
WARNING
(For using R290/R32 refrigerant only)

IMPORTANT SAFETY INSTRUCTIONS CONTINUED
13
18. Labelling
• Equipment should be labelled stating that it has been de-commissioned and emptied of
refrigerant. The label should be dated and signed. Ensure that there are labels on the equipment
stating the equipment contains ammable refrigerant.
19. 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-o 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 ammable 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 ammable 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 should be employed
to accelerate this process. When oil is drained from a system, it should be carried out safely.
