SERVICING INSTRUCTIONS 1.1 Area check Before starting work on a system containing flammable refrigerants, safety checks are necessary to ensure that the risk of ignition is minimized. When repairing a cooling system, the following measures must be adhered to prior to performing any work. 1.2. Work procedure Work must be performed following a  controlled procedure so that the risk of flammable gases or fumes being present during this time is minimised. 1.3 General work area The whole maintenance crew and other personnel at the site must be informed about the nature of the works being performed. Work in tight areas must be prevented. The area around the work site must be divided into sections. It must be ensured that the conditions inside the area are safe by means of inspections of flammable materials. 1.4 Check for presence of a refrigerant The area must be checked using an appropriate detector for the presence of refrigerant before and during work to ensure that technicians are aware of a potentially flammable atmosphere. It must be ensured that the device used for the detection of leaks is suitable for use on flammable refrigerants, i.e. non-sparking, appropriately sealed or intrinsically safe. 1.5 Presence of a fire extinguisher In the event that any work is performed on the cooling device or associated parts under heat, then a suitable fire extinguisher must be on hand. In the vicinity of the filling area, there must be a powder or CO2 fire extinguisher. 1.6 No ignition sources No person performing work related to the cooling system that encompasses the uncovering of any pipes that contain or have contained flammable gasses may use any ignition sources in a  manner that could lead to a  fire or explosion hazard. All possible ignition sources, including the smoking of cigarettes should be kept at a sufficient distance from the installation, repair, removal or disposal location, during which flammable refrigerant could potentially be released into the surrounding environment. Prior to starting work, the area around the appliance must be checked to ensure that there are no fire hazards or ignition risks present. A "smoking forbidden" sign must be installed. 1.7 Ventilated area It must be ensured that the area is ventilated or appropriately ventilated prior to penetrating the system or performing any work under heat. The intensity of ventilation must continue for the time that works are performed. Ventilation should safely dissipate any released refrigerant and draw it out into the atmosphere as a priority. 1.8 Cooling system checks In places where electrical components are replaced, these components must be suitable for this purpose and conform to correct specifications. The manufacturer's instructions for maintenance and service must always be followed. If any doubts arise, it is necessary to request help from the manufacturer's technical department. On installations containing flammable refrigerants, it is necessary to perform the following checks: the amount of refrigerant corresponds to the size of the room in which components

containing refrigerant are installed; ventilation systems and outlets are in full working order and are not clogged; if any indirect cooling circuit is used, the second circuit must be checked for the

presence of refrigerant; the markings on the appliance must remain constantly visible and legible, and

marking and signs that are illegible must be repaired; The cooling pipes and components are installed in locations where it is not probable

that they will be exposed to any substances that could corrode the parts containing refrigerant, unless these components are built using materials that are inherently resistant to corrosion or are appropriately protected against corrosion.

1.9 Electrical device check The repair and maintenance of electrical components must include safety checks and inspections of components. In the event of a  malfunction that could affect safety, no electrical power may be connected to the circuit until the malfunction is satisfactorily resolved. In the event that the malfunction cannot be immediately repaired but it is necessary to continue running the appliance, an appropriate temporary solution must be used. The owner of the appliance must be informed in such a way that all parties know about it. The initial safety check must ensure: that capacitors are discharged: this must be performed in a safe way to prevent the

possibility of sparking; that no electrical components or wiring is uncovered during the process of filling,

draining or cleaning the system; that the grounding is not interrupted.

2. Repair of sealed components When repairing sealed components, all the electrical power supply must be disconnected from the appliance on which work is being performed before sealed lids, etc. are removed. When it is absolutely necessary to have live power supply going into the appliance while servicing the appliance, it is necessary to install a permanent device in the most critical point to detect leakage so that a  dangerous situation is averted. Special attention must be paid to ensuring that as a result of the work performed on electrical components the cover is not changed to the extent of affecting the level of protection. This must also include damage to cables, excessive number of connections and terminals not performed according to original specifications, damaged gaskets, incorrect configuration of plugs, etc. It is necessary to ensure that the appliance is mounted safely. It is necessary to ensure that gaskets or sealing materials are not damaged in such a way that they no longer serve to prevent the entry of a flammable atmosphere. Spare parts must conform to the manufacturer's specifications.

NOTE: The use of silicone gaskets and seals may suppress the efficiency of certain type of leak detection devices. Intrinsically safe components do not need to be disconnected prior to being worked on.

3. Repairs of intrinsically safe components No permanently inductive or capacitative load may be placed on the circuit without it being ensured that thereby the permitted voltage and current for the used appliance is not exceeded. Intrinsically safe components are the only type on which it is possible to work in a flammable environment even while under live current. Testing equipment must have correct specifications. Parts are replaced using only parts specified by the manufacturer. Different parts could result in ignition of refrigerant upon leakage into the environment. 4. Cabling Check that cabling is not exposed to wear and tear, corrosion, excessive pressure, vibrations, sharp edges or any other negative environmental effects. This check must also take into consideration the effects of ageing and permanent vibrations from sources such as compressors or fans. 5. Detection of flammable refrigerants Under no circumstances may potential sources of ignition be used for locating or detecting refrigerant leaks. A halogen burner (or any other type of detector utilising an open flame) must not be used. 6. Leak detection methods The following leak detection methods are considered acceptable for systems containing flammable refrigerants. For the detection of flammable refrigerants, electronic leak detectors must be used, however their sensitivity may not be appropriate or they may require recalibration. (Detection equipment must be calibrated in an area without any refrigerant present). It is important to ensure that the detector is not a potential ignition source and that it is suitable for the used refrigerant. The leak detector must be set to a percentage of LFL refrigerant and must be calibrated for the used refrigerant and the respective gas percentage is confirmed (maximum 25 %). Leak detection liquids are suitable for use on most refrigerants, however, detergents containing chlorine must be excluded since chlorine may react with the refrigerant and corrode copper pipes. In the event of a suspected leak, all open flames must be removed/extinguished. In the event that the refrigerant leak is found and requires hard soldering, then all the refrigerant must be drained from the system or separated (by closing a valve) in a part of the system distant from the leak. The system must then be cleaned out using oxygen-free nitrogen (OFN) both before as well as after the hard soldering process. 7. Collection and pump discharge In the event that the cooling circuit is breached due to repairs or for any other reason conventional procedures must be followed. It is, however, important to adhere to the best method due to flammability. It is necessary to adhere to the following procedure: collect the refrigerant; clean out the circuit using inert gas; pump out; again clean out using inert gas; open the circuit by cutting or hard soldering.

The contents of the circuit must be collected into correct collection cylinders. The system must be "flooded" with OFN (oxygen-free nitrogen) for the unit to remain safe. It may be necessary to repeat the procedure several times. For this task, neither compressed air nor oxygen may be used. Flooding may be achieved by disrupting the vacuum in the system with the use of OFN, and by continued filling until the operating pressure is achieved, then venting into the atmosphere and finally lowering to a vacuum. This process must be repeated if refrigerant still remains in the system. When the last OFN cartridge is used, the system must be ventilated to atmospheric pressure to enable work to be performed. This activity is absolutely necessary if hard soldering is to be performed on the pipes. It is necessary to ensure that the vacuum pump outlets are not nearby to any ignition source, and ventilation must be provided. 8. Filling procedure Apart from conventional filling procedures, also the following requirements must be adhered to. It is necessary to ensure that no contamination by various refrigerants occurs when

the filling device is used. Hoses or pipes must be as short as possible to minimise the amount of refrigerant contained inside of them.

Cylinders must be held vertically. It is important to ensure that the cooling system is grounded prior to being filled

with refrigerant. When filling is complete, the system must be marked with a label (if it does not have

one already). It is necessary to pay extreme care to ensure that the cooling system is not overfilled. A pressure test using OFN must be performed before refilling the system. In the case of a  leak, the system must be tested after being refilled but also before being put into operation. A verification test must be performed before leaving the installation location. 9. Taking out of operation Prior to performing this procedure it is essential that the technician fully acquaints him/herself with the device and all its particulars. Correct practice of safely collecting all refrigerant is recommended. Prior to performing this activity, oil and refrigerant samples must be taken if an analysis is required prior to using the using the regenerated refrigerant for the first time. It is essential that prior to starting this activity that electricity is available.

a) Acquainting one's self with the device and its activity. b) Electrical disconnection of the system. c) Prior to starting the procedure, ensure that: if required, mechanical device for handling the cylinder with refrigerant is available; all personal protective devices are available and used correctly; the collection process is constantly under the supervision of a competent person; the collection device and cylinders comply with respective norms.

d) Pump out the cooling system if possible. e) If achieving vacuum is not possible, collection pipes are created to enable the

collection of refrigerant from various parts of the system. f ) Ensure that the cylinder is placed on the scale before the collection of refrigerant is

started. g) The collection device is turned on and runs according to the manufacturer's

instructions. h) Cylinders are not overfilled. (No more than 80% of liquid content capacity). i) The maximum operating pressure of the cylinder is not exceeded, even temporarily. j) When the cylinders are properly filled up and the procedure is complete, ensure that

the cylinders and devices are immediately removed from the installation location and that all the separation valves on the device are closed.

k) The collected refrigerant must not be filled into a different cooling system until it is cleaned and checked.

10. Marking with a label The appliance must be marked with a  label indicating that it has been put out of operation and is without refrigerant. The label must be dated and signed. It is ensured that there are labels on the appliance indicating that it contains flammable refrigerant. 11. Collection When the refrigerant is collected from the system, either due to servicing or when it is put out of operation, it is recommended to adhere to proper practice and safely collect all the refrigerant. When the refrigerant is transferred into the cylinders, it is necessary to ensure that appropriate cylinders for collecting refrigerant are used. It is necessary to ensure that there is a  sufficient number of cylinders available to contain the complete contents of the system. All the cylinders that are to be used must be intended for collecting refrigerant and be marked with a label for this refrigerant (i.e. special cylinders for collecting refrigerant). The cylinders must be complete with a  safety valve and associated closing valves in good working condition. The empty collection cylinders are pumped empty and if possible cooled prior to collecting refrigerant. The collection device must be in good operating condition with a  set of manuals relating to the device, which are on hand and it must be suitable for collecting flammable refrigerants. Apart from this, a set of calibrated scales in good operating condition must also be available. Hoses must be complete with couplers without seepage and in good condition. Prior to using the collection device, check that it is in satisfactory operating condition, has been properly maintained and all the associated electrical components are sealed to prevent ignition in the event of refrigerant being released. If in any doubt, consult the manufacturer. The collected refrigerant must be returned to the refrigerant supplier in the correct collection cylinder and with a respectively arranged waste transport letter. Refrigerants are not mixed in the collection units and especially not in the cylinders. In the event that compressors or compressor oils are to be collected, ensure that they are pumped out to an acceptable level in order to ensure that flammable refrigerant does not remain in the lubricant. The pump discharge process must be performed before the compressor is returned to the supplier. To speed up this process, only electrically heated compressor elements may be used. When the oil is drained from the system, it must be disposed of safely.
