1. Transport of equipment containing combustible refrigerants (Appendix CC.1)

Observe the transport instructions.

2. Marking equipment with signs (Appendix CC.2)

Observe local regulations.

3. Disposal of equipment containing combustible refrigerants (Appendix CC.3)

Observe national regulations.

4. Storage of equipment/appliances (Appendix CC.4)

Store equipment in accordance with instructions from the manufacturer.

5. Storage of packaged (unsold) equipment (Appendix CC.5)

The storage packaging must have such a sturdy design that no refrigerant can start to leak when the equipment is mechanically damaged in the packaging. Local regulations determine the maximum number of appliances that can be stored in one room.

6. Information about maintenance (Appendix DD.3)

1) Check the surrounding area

Prior to working at systems containing combustible refrigerants, safety checks are required to make sure that the risk of ignition islimited to a minimum. When repairing cooling systems, take the following precautions before performing work at the system.24 • English

2) Working procedure

Perform work in accordance with a regulated procedure to minimize the risk of released combustible gases or vapours during the work.

3) General work area

Inform all maintenance personnel and others working in the vicinity of the nature of the work to be performed. Avoid working in enclosed spaces. Demarcate the area around the workplace. Make sure the work area is safe by checking for the presence of combustible material and ignition sources.

4) Check for the presence of refrigerant

Check the area prior and during the work with a suitable refrigerant detector, which will warn the technician for the presence of possibly combustible ambient air. Only use leak detection equipment that is suitable for use with combustible refrigerants, i.e. free from sparks, adequately guarded or intrinsically safe.

5) Keep a fire extinguisher within reach

If hot work must be performed at cooling equipment or related parts, suitable extinguishing agents should be present within reach. Immediately next tot he filling area, mount a powder extinguisher or CO2 extinguisher.

6) Keep ignition sources at a distance

Anyone performing work at a cooling system whereby pipes (once) containing combustible refrigerant are laid bare, may notuse ignition sources that could cause a fire or an explosion. Keep all possible ignition sources, including lighted cigarettes, sufficiently far removed from the place of installation, repair or disposal, where combustible refrigerant could be released inthe environment. Check prior to performance of the work that there are no combustible materials or ignition sources inthe area around the equipment. Hang warning signs with the text “Smoking prohibited”.

7) Provide ventilation

Work in the open air or ensure that the work area is sufficiently ventilated before you open the system or perform hot work. Continuously ensure sufficient ventilation during the performance of the work. The ventilation should blow away any released refrigerant to a safe place and preferable discharge it to the outdoor air.

8) Check the cooling equipment

Replace electric components only by equivalent parts that meet the correct specifications. Always observe the manufacturer’s guidelines for maintenance and repair. In case of doubt, contact the technical support service of the manufacturer for support. Check installations using combustible refrigerants regarding the following: - The filling volume should correspond with the dimensions of the room in which the refrigerant containing components are installed; - The ventilation equipment and exhausts should work properly and may not be blocked. - If an indirect cooling circuit is being used, the secondary circuit must be checked for the presence of refrigerant; - All markings on the equipment must be visible and legible. Repair in advance all markings and signs that have become illegible; - Cooling pipes and components containing refrigerant must be installed in such a way that they are unlikely exposed to substances that may affect them, provided the components are not made of materials that are inherently resistant to corrosion or are adequately protected against corrosion.

9) Check electrical appliances

In the event of repair and maintenance of electrical components, always first check them for safety and observe the inspection procedures for the components. If there is a failure that could jeopardise safety, no electrical power supply may be connected tothe circuit before this failure has been resolved. If the failure cannot immediately be resolved, but the appliance must remain operational, a suitable temporary solution must be achieved. Always report this to the owner of the equipment, sothatall involved parties are informed. Safety checks in advance include:

• Discharging condensers: this should be done in a safe way to prevent the creation of sparks;

• Check that there are no live electrical components and wires lying bare when filling, draining or flushing the system;

• Check that the continuity of the earthed connections is guaranteed.

7. Repairs to guarded components (Appendix DD.4)

1) When performing repairs to guarded components, disconnect all electrical power supplies from the equipment being

work on, before removing the cover plates, etc.. If it is absolutely necessary to keep the power supply switched on during maintenance to the equipment, a permanently active leak detector should be installed at the most critical point to warn for the occurrence of possibly hazardous situations. 2) Pay extra attention to the following, to make sure that the housing is not changed in such a way during work at electrical components that the protection level is affected. You could think of damaged cables, making too many attachments per connection, clamps that do not meet the original specifications, damaged seals, incorrect assembly of gaskets, etc. Make sure the equipment is firmly attached. Check that seals and sealing materials are still sufficiently able to prevent penetration of combustible ambient air. Onlyuse replacement parts that meet the manufacturer’s specifications. CAUTION: The use of silicone containing sealing agents could disrupt the operation of some types of leak detection equipment. Intrinsically safe components do not have to be disconnected before working at them.English • 25

8. Repairs to intrinsically safe components (Appendix DD.5)

Do not connect permanently inductive or capacitive loads to the circuit without checking if the allowed voltages and currents for the equipment used are exceeded as a result. Intrinsically safe components are the only types of component at which you are allowed to work while they are live in the presence of flammable ambient air. Only use test equipment with the correct certifications. Only replace components by parts that correspond with the manufacturer’s specifications. The use of deviating parts could cause fire when refrigerant escapes to the ambient air as a result of a leak.

9. Cables (Appendix DD.6)

Check that the cables are not exposed to wear, corrosion, excessive pressure, vibrations, sharp edges or other negative ambient influences. When checking, also consider the consequences of ageing and constant vibration of compressors or fans.

10. Detection of combustible refrigerants (Appendix DD.7)

Never use potential ignition sources when looking for or tracing refrigerant leaks. Do not use a halogen lam (or any other detector with an open flame).

11. Leak detection methods (Appendix DD.8)

The following leak detection methods may be used for systems containing combustible refrigerants. Preferably use electronic leak detectors to detect combustible refrigerants. Sometimes the sensitivity of such equipment isnot sufficient, or they must be recalibrated. (Always calibrate detection equipment in a room that is free from refrigerant.) Check that the detector is not a potential ignition source and that it is suitable for the refrigerant used. Adjust the leak detection equipment at a percentage of the refrigerant’s LFL (lower flammable limit) and calibrate the equipment to the refrigerant used and the correct gas percentage (maximum 25%). Leak detection liquids are also suitable for use with most refrigerants, but avoid the use of chlorinated substances, as the chlorine could also react with the refrigerant and affect the copper piping. If a leak is suspected, all open flames must be extinguished or removed. If a refrigerant leak is found that requires soldering, all refrigerant should first be drained from the system, or the refrigerant should be isolated (by means of valves) in a section of the system away from the leak. Then flush the system with oxygen free nitrogen (OFN), both prior to and during the soldering process.

12. Draining and emptying (Appendix DD.9)

When opening a cooling circuit in order to perform repairs - as well as for all other purposes - the correct regulations and procedures should be observed at all times. In addition, always try to work as safely as possible, due to the flammability ofthe refrigerants. For that reason, always use the following procedure:

• Remove the refrigerant;

• Flush the circuit with inert gas;

• Flush once more with inert gas;

• Open the circuit by sawing or soldering. Collect the refrigerant in a suitable storage container. Flush the system with OFN (oxygen free nitrogen) to make the system safe. It is possible that you must repeat this process a few times. Never use compressed air or oxygen to flush a system. Flush the vacuum system by allowing OFN to flow into it and then fill the system with OFN until the operating pressure is achieved. Then allow this to escape to the atmosphere and make the system vacuum again. Repeat this process until there is no more refrigerant in the system. After the last OFN flush, the system must be de-aerated to atmospheric pressure to make the work possible. This is an absolute condition when soldering work has to take place at the piping. Ensure that the exhaust of the vacuum pump is not in the vicinity of ignition sources and that the surrounding area is sufficiently ventilated.

13. Filling procedures (Appendix DD.10)

In addition to the standard procedures when filling, also observe the following requirements. - When using the filling equipment, prevent different refrigerants from getting mixed. Hoses and pipes must be as short aspossible to minimise the amount of refrigerant that they contain. - Always place cylinders upright. - Earth the cooling system before filling the system with refrigerant. - Mark the system when it is filled (if this has not yet been done). - Ensure the cooling system is not excessively filled. Perform a pressure test with OFN (oxygen free nitrogen) before filling the system. Check the system for leaks after filling, butbefore commissioning. Always perform a final leak test before leaving the location.

14. Decommissioning (Appendix DD.11)

In order to perform this procedure, it is essential that the technician has fully familiarised himself with the equipment and allits parts. It is always recommended to drain and dispose the refrigerants used safely. Prior to the work, always take an oil and refrigerant sample when reuse of the drained refrigerant requires prior analysis. It is essential to check whether there isa power supply present, before starting the work. a) Familiarize yourself with the equipment and its operation. b) Disconnect the electrical connection between the system nd the power supply. c) Prior to starting the work, check that the following items have been met:

• All required mechanical provisions are present, e.g. to handle the refrigerant cylinders;

• All personal protective equipment is present and is used correctly;

• There is always a competent person present who supervises the draining process;26 • English

• All draining equipment and storage cylinders comply with the applicable standards. d) Preferably pump empty the cooling system, if this is possible. e) If pumping empty is not possible, use a suitable distributor to remove as much refrigerant as possible from the different sections of the system. f) Place the cylinder on the weighing scale before draining starts. g) Start the draining system and work in accordance with the manufacturer’s instructions. h) Never fill cylinders by more than is permitted. (Maximum 80% liquid volume).

i) Never exceed the maximum operating pressure of the cylinder, not even briefly.

j) When the cylinders are filled correctly and the process has been completed, immediately remove all cylinders and equipment from the location and close all valves of the equipment. k) Never fill drained refrigerant in another cooling system, before cleaning and checking it.

15. Marks (Appendix DD.12)

Apply markings on the equipment stating that it has been decommissioned and that the refrigerant has been removed. Write the date on the marking, as well as your name. Apply markings on the equipment indicating that the equipment contains combustible refrigerant.

16. Draining (Appendix DD.13)

When removing refrigerant from a system, for maintenance or decommissioning, it is recommended to remove all refrigerants to a safe location. When draining refrigerant, only use cylinders that are suitable for storing refrigerant. Ensure there are sufficient cylinders available to store the entire volume of the cooling system. Only use cylinders that are suitable for storing the refrigerant to be drained and apply markings indicating which refrigerant they contain (i.e. use special storage cylinders). The cylinders must be complete, including properly functioning overpressure valves and valves. Pump empty storage cylinders empty and cool them, if possible, before gas is stored in them. The draining system must be in a good condition and have a manual describing the equipment used, and must be suitable forcollecting combustible refrigerants. In addition, a calibrated weighing scale should be available that is working correctly. All hoses should be provided with coupling that work correctly and are free from leaks. Prior to using the draining system, check that it is in a good conditions, well maintained and that all accompanying electrical components are sufficiently guarded to prevent ignition in the event of a refrigerant leak. In case of doubt, consult the manufacturer. Hand in the collected refrigerant in the correct storage cylinder at the refrigerant supplier and ask for a receipt for the submitted waste materials. Do not mix refrigerants in the draining system and certainly not in the cylinders. If compressors or compressor oils must be removed, first empty the appliance to a level at which no combustible refrigerant remains in the lubricant. Emptying should take place before the compressor is sent back to the supplier. The compressor body may only be heated electrically in order to accelerate the process (not with an open flame). When oil must be removed from a system, do this in a safe way. This product is labelled with this crossed out wheel bin symbol in accordance with European Directive 2012/19/EC to indicate that it must not be disposed of with your other household waste. Due to the presence of hazardous substances, mixtures or components, electrical and electronic devices that are not subject to selective sorting are potentially dangerous to the environment and human health.
