10. Instructions for service technicians
Information addressed to specialists. They serve only as guidance for qualified personnel.
Any person involved in opening or draining the system should have a current and valid certificate confirming their competence to safely handle
flammable refrigerants.
1. Preparation for safe work
Before starting work on systems containing flammable refrigerants, a safety check should be carried out to minimize the risk of ignition. When repairing the
refrigeration system, the following precautions must be followed before working on the system.
2. Work procedure
The work should be carried out in accordance with a controlled procedure, which will minimize the risks associated with the presence of flammable gas or vapor
during the activity.
3. General work area
Service personnel and others working in the vicinity should be briefed on the type of service work to be performed. Avoid working in confined spaces. The area
around the workplace should be separated. Make sure the area is safe, i.e. no flammable materials are present.
4. Check for the presence of refrigerant
The area should be checked with a suitable refrigerant leak detector before and during the work so that the service technician is aware of working in a potentially
hazardous atmosphere. Make sure that the leak detector used for leak detection is suitable for all refrigerants used, i.e. non-sparking, properly sealed or inherently
safe.
5. Fire extinguisher availability
If work, involving the use of a torch, is to be performed on refrigeration equipment or related components, appropriate fire extinguishing equipment (i.e. CO2 powder
or carbon dioxide extinguisher) should be on hand.
6. No sources of ignition
No person carrying out work on the refrigeration system, that involves exposing the piping, should use any source of ignition in a way that could lead to fire or
explosion. Any potential sources of ignition should be kept away from any installation, repair, disassembly or disposal where there is a risk of release to the
environment. Before starting work, assess the area around the unit for potential hazards from flammable materials or sources of ignition. "No Smoking" signs must be
posted.
7. Area ventilation
Ensure that the area is open and sufficiently ventilated before starting any work involving the opening of the system or work involving the use of a torch. Adequate
ventilation must be ensured during the work. Ventilation should safely and effectively disperse the refrigerant and optimally discharge it to the outside to the
atmosphere.
8. Control of refrigeration equipment
When replacing electrical parts, use components that are suitable for the application and comply with the specifications. The manufacturer's maintenance and service
instructions must be followed at all times.
If in doubt, consult the manufacturer's technical department.
For systems using flammable refrigerants, check:
• whether the amount of refrigerant corresponds to the area of the room where the refrigerant-containing components are installed;
• that the ventilation devices are working properly and their air outlets are not blocked;
• whether the secondary circuit contains refrigerant when using an indirect refrigeration system;
• whether the markings on the devices remain visible and legible. Illegible markings and symbols should be corrected;
• that pipes or components containing refrigerant are installed in a position that prevents them from being exposed to corrosive substances, unless the components
are made of corrosion-resistant materials or are suitably protected against corrosion.
9. Control of electrical devices
Repair and maintenance of electrical components should include initial safety checks and component inspection procedures. If there is a fault that could compromise
safety, do not connect the power supply until the problem is solved. If the fault cannot be rectified immediately and operation must be resumed, an appropriate
temporary solution must be applied. The owner of the device should be informed about the situation so that people around are aware of it.
The initial security check requires checking:
• whether the capacitors have been discharged; the operation must be carried out in such a way as to avoid sparking;
• that no electrical components or wiring are exposed during refrigerant charging and recovery or purging the system;
• that grounding is provided.
10. Repairs to sealed components
When repairing sealed components, disconnect all electrical connections to the unit before removing the sealing covers, etc. If electrical power to the unit is required
during maintenance, then a continuously operating leak detection form should be placed at the most critical point to warn of a potentially hazardous situation.
When working with electrical components, care must be taken to ensure that the enclosure is not altered in a way that may affect its safety level. This includes
damage to electrical wires, excessive number of connections, connections not made in accordance with the technical specification, damage to seals, incorrect
adjustment of glands, etc.
• Make sure that the device is properly mounted.
• Make sure that gaskets or sealing materials are not worn to the extent that they cannot perform their function. Spare parts should comply with the manufacturer's
technical data.
Attention!
The use of a silicone sealant may reduce the effectiveness of some leak detection equipment. Elements that are safe in themselves do not need to be
insulated before starting work.
11. Repair of safe components
Do not apply any permanent inductive or capacitive loads without making sure that they do not exceed the permissible voltage and current values. Safe components
are the only types of components that can be worked on under voltage in a flammable atmosphere. Testing equipment should be properly rated. Components should
only be replaced with parts specified by the manufacturer. The use of other parts may cause the refrigerant to ignite due to leakage.
12. Wiring
Make sure that the wiring will not be exposed to wear, corrosion, excessive pressure, vibration, sharp edges or other undesirable factors. Inspection should also
consider the effects of time or constant vibration from sources such as compressors or fans.
13. Detecting the presence of flammable refrigerants
Under no circumstances should potential sources of ignition be used to detect or search for refrigerant leaks. Do not use a halogen torch (or other open flame
detectors).
14. Leak detection methods
The following leak detection methods are considered acceptable for refrigeration systems containing flammable refrigerants. Electronic detectors can be used to
detect refrigerant leaks. However, their sensitivity may be insufficient or they may need to be recalibrated. (Calibrate leak detection equipment in a refrigerant-free
area.) Make sure that the detector is not a potential source of ignition and is suitable for the refrigerant used. Leak detection equipment should be set to the lower LFL
percentage of the refrigerant and calibrated for the refrigerant used. The appropriate gas percentage (25% maximum) must also be confirmed.

10. Instructions for service technicians cont.
Leak detection fluids are suitable for use with most refrigerants, but avoid using detergents that contain chlorine, which can react with the refrigerant to corrode
copper pipes.
If a leak is suspected, remove/extinguish all naked flames. If brazing is required when a leak is detected, completely recover the refrigerant from the system or isolate
(using shut-off valves) the part of the system away from the leak. For units containing flammable refrigerants, purge the system with oxygen-free nitrogen (OFN)
before and during the brazing process.
15. Removing and emptying
Standard procedures should be followed when opening the refrigerant circuit for repair or any other purpose. In the case of flammable refrigerants, it is important to
take special care due to the risk of ignition. Follow the procedure below:
• remove the refrigerant;
• purge the system with inert gas;
• empty;
• purge with inert gas again;
• open the system by cutting or brazing.
The refrigerant must be recovered in suitable cylinders. To ensure equipment safety, flush the system with OFN (Oxygen Free Nitrogen). The procedure needs to be
repeated several times. Do not use compressed air or oxygen for this purpose.
Purge should be carried out by breaking the vacuum in the system with OFN (oxygen-free nitrogen) and continue filling until working pressure is reached, venting to
atmosphere and finally lowering to vacuum. The process must be repeated until the system is completely empty of refrigerant.
After the last dose of OFN (oxygen-free nitrogen) has been applied, the system must be purged to atmospheric pressure to allow work to be done. This step is
essential if you will be brazing the tubing.
Make sure that the outlet of the vacuum pump is away from sources of ignition and that the environment is adequately ventilated.
16. Refrigerant charge procedures
In addition to standard filling procedures, the following requirements must be followed.
• Ensure that there is no contamination with various refrigerants when using the filling equipment. Keep hoses and lines as short as possible to minimize the amount
of refrigerant they contain.
• Keep the cylinder in an upright position.
• Before charging the system with refrigerant, make sure that the refrigeration system is grounded.
• Label the installation after filling (if not already done).
• Be careful not to overcharge the system with refrigerant.
• Pressure test with oxygen-free nitrogen before refilling the system. The system should be checked for leaks after filling is complete but before commissioning.
Perform the sealing procedure again before leaving the installation site.
17. Decommissioning
Before performing this procedure, make sure that the technician is thoroughly familiar with the device and all its details. Safe recovery of the refrigerant is
recommended. An oil and refrigerant sample should be taken prior to the task in case analysis is required before reusing the reclaimed refrigerant. Make sure that
electrical power is available before carrying out the task.
a. Familiarize yourself with the device and how to use it.
b. Electrically isolate the system.
c. Before performing the procedure, ensure that:
- Mechanical refrigerant cylinder handling equipment is available;
- Personal protective equipment is available and properly used;
- The recovery process is constantly supervised by a competent person;
- The equipment and the recovery cylinder comply with the relevant standards.
d. Drain the refrigeration system if possible.
e. If a vacuum cannot be achieved, a manifold must be made to allow the refrigerant to be drained from various parts of the system.
f. Make sure the cylinder is on the scale before starting recovery.
g. Operate and operate the recovery equipment in accordance with the manufacturer's instructions.
h. Do not overfill the cylinder. (Do not fill over 80% of the fill volume).
i. Do not exceed the cylinder's maximum working pressure, even temporarily.
j. After the cylinders are properly filled and the procedure is complete, ensure that the cylinders and equipment are immediately removed from the work area and all
shut-off valves on the equipment are closed.
k. Reclaimed refrigerant may only be charged to another system after it has been cleaned and inspected.
18. Labeling
Equipment must be labeled that it has been decommissioned and emptied of refrigerant. The label must be dated and signed. Make sure there is a label on the unit
that there is flammable refrigerant inside.
19. Recovery
• When removing refrigerant from the system for service or decommissioning, good practice is recommended to ensure that all refrigerant is safely recovered.
• When transferring refrigerant to cylinders, ensure that only appropriate cylinders are used. Make sure there are enough of them available to recover refrigerant from
the entire system. All cylinders used should be dedicated to reclaimed refrigerant and properly marked (special refrigerant recovery cylinders). Cylinders should be
complete with safety valve and shut-off valves in good technical condition.
• Empty recovery cylinders are vented and, if possible, cooled before recovery begins.
• Recovery equipment should be in good working order, complete with instructions and designed to recover all relevant refrigerants, including flammable refrigerants
where applicable. In addition, an available set of operational, properly calibrated scales is required.
• Hoses should be in good technical condition and equipped with tight joints. Before using recovery equipment, ensure that it is in good working order and has been
well maintained and that all associated components are insulated to prevent ignition in the event of a refrigerant leak. If in doubt, consult the manufacturer.
• The recovered refrigerant must be returned to the supplier in the appropriate cylinder with the appropriate waste transfer document. Do not mix different refrigerants
in recovery equipment, especially in cylinders.
• If it is necessary to remove the compressor or its oil, ensure that they have been drained to an acceptable level to ensure that refrigerant residues are not in the
lubricant.
The draining procedure must be performed before the compressor is delivered to the supplier. The process can be accelerated by heating the compressor body.
Remove the oil from the system safely.
