7. Repairs to Sealed Components
1) During repairs to sealed components, all electrical supplies shall be disconnected from the unit
being worked on prior to the removal of sealed covers and other parts (if any). If it is necessary
to have an electrical supply connected to the unit 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 when 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 the cables, an excessive number of connections, terminals not made to
the original specication, damage to seals, incorrect tting of glands, etc.
Ensure that the unit is mounted securely.
Ensure that the seals or sealing materials have not been degraded to a point that they no longer
serve the purpose of preventing the ingress of ammable atmospheres. Replacement parts shall
be in accordance with the manufacturer's specications.
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.
8. Repair to Intrinsically Safe Components
Do not apply any permanent inductive or capacitive loads to the circuit without ensuring that this will
not exceed the permissible voltage and current for the unit in use. Intrinsically safe components are
the only types that can be worked on while live and in the presence of a ammable atmosphere. The
test apparatus shall be at the correct rating. Replace the components only with parts specied by the
manufacturer. Other parts may result in the ignition of refrigerant in the atmosphere from a leak.
9. Cabling
Check that the cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp
edges, or any other adverse environmental effects. The check shall also consider 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 searching for or detecting
refrigerant leaks. A halide torch (or any other detector using a naked ame) shall not be used.
11. 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 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
conrmed.
• 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 shall be removed/ extinguished. If a refrigerant leak is
found (which requires brazing), all refrigerants shall be recovered from the system, or isolated (by
means of shut off valves) in a part of the system that is situated remotely from the leak. Oxygen
free nitrogen (OFN) shall then be purged from 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. Considering ammability, follow best practices. Opening of the refrigeration
systems shall not be done by brazing. Adherence to the following procedures is a must:
a) Removing the refrigerant;
b) Purging the circuit with inert gas;
c) Evacuation;
d) Purging again with inert gas;
e) Opening the circuit by cutting or brazing;
The refrigerant charge shall be recovered into the correct recovery cylinders. The system shall 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 shall be achieved by breaking the vacuum in the system with OFN and continuing to ll
until the working pressure is achieved, then venting to the atmosphere, and nally pulling down to a
vacuum. This process shall be repeated until no refrigerant is inside 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 near any ignition sources and that ventilation is
available.
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 the charging
equipment. Hoses or lines shall be as short as possible to minimize the amount of refrigerant
contained in them.
• Cylinders shall be kept upright.
• Ensure that the refrigeration system is earthed before charging the system with the refrigerant.
Label the system when the charging is complete (in case it has not been labeled yet).
• Extreme care shall be taken to avoid overlling the refrigeration system.
• Prior to recharging the system, the pressure test with OFN must rst be conducted. The
system leak test shall be performed upon completion of charging, but should be done prior to
commissioning. Afollow up leak test shall be carried out before leaving the site.
14. Decommissioning
Before carrying out this procedure, it is essential that the technician is completely familiar with the
equipment and all necessary details. It is good practice that all refrigerants be recovered safely. Prior
to carrying out this task, an oil and refrigerant sample shall be taken in case analysis is required before
reusing the reclaimed refrigerant. It is essential that electrical power is available before this task
commences.
a) Become familiar with the equipment and its operation.
b) Isolate the system electrically.
c) Before attempting the procedure, ensure that:
Mechanical handling equipment is available, if required, for handling refrigerant cylinders;
Allpersonal protective equipment is available and being used correctly;
The recovery process is always supervised by a competent person and recovery equipment and
cylinders conform to the required standards.
d) Pump down the refrigerant system, if possible.
e) If a vacuum is not possible, make a manifold so that refrigerants can be removed from various
parts of the system.
f) Make sure that the cylinder is situated on the scales before recovery takes place.
g) Start the recovery machine and operate in accordance with the manufacturer's instructions.
h) Do not overll the 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 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 off.
Important Safety Instructions Important Safety Instructions

k) Recovered refrigerant shall not be charged into another refrigeration system unless it has been
cleaned and checked.
15. Labeling
The unit shall be labeled stating that it has been decommissioned and emptied of the refrigerant.
The label shall be dated and signed. Ensure that there are labels on the unit stating that it contains
ammable refrigerants.
16. Recovery
When removing the refrigerant from a system, either for servicing or decommissioning, it is
recommended that all refrigerants be removed safely.
When transferring the refrigerant into the cylinders, ensure that only appropriate refrigerant recovery
cylinders are used. 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 labeled for that
refrigerant (i.e., special cylinders refrigerant recovery). Cylinders shall have pressure relief valves and
associated shut-off valves in good working order. Empty recovery cylinders should be evacuated and, if
possible, cooled before the 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 be 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 if a refrigerant is released. Consult
Customer Service when 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 the compressors or the compressor oils are to be removed, ensure that they have
been evacuated to an acceptable level so that the 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 shall be employed to accelerate this process.
When oil is drained from the system, it shall be done in a safe manner.
