6-1 Checks to the area Prior to beginning work on system containing ammable refrigerants, safety checks are necessary to ensure that the risk of ignion is minimized. For repair to the refrigerang system the following precauons shall be complied with41 prior to conducng work on the system. 6-2 Work procedure Work shall be undertaken under a controlled procedure so as to minimize the risk of ammable gas or vapour being present while the work is being performed. 6-3 General work area All maintenance sta and others working in the local area shall be instructed on the nature of work being carried out. Work in coned spaces shall be avoided. The area around the workspace shall be seconed o. Ensure that the condionswithin the area have been made safe by control of ammable material. 6-4 Checking for presence of refrigerant The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician is aware of prtenally ammable atmospheres. Ensure that hte leak detecon equipment being used is suitable for use with ammable refrigerants, i.e. non- sparking adequately sealed or intrinsically safe. 6-5 Presence of re exnguisher If any hot work is to be conducted on the refrigeraon equipment or any associated partsappropriate re exnguishing equipment shall be avalaible to hand. Have a dry powder or CO

re exnguisher adjacent to the charging area. 6-6 No ignion sources No person carrying out work in relaon to a refrigeraon system which involves exposing any pipe work that contains or has contained ammable refrigerant shall use any sources of ignion in such a manner that it may lead to the risk of re or explosion. All possible ignion sources, including cigaree smoking, should be kept suciently far away from the site of installaon, repairing, removing and disposal, during which ammable refrigerant can possibly be released to the surrounding space. Prior to work taking place, the area around the equipment is to be surveyed to make sure that there are no ammable hazards or ignion risks. “No Smoking” signs shall be displayed. 6-7 Venlated area Ensure that the area is in the open or that it is adequately venlated before breaking into the system or conducng any hot work. A degree of venlaon shall connue during the period that the work is carried out. The venlaon should safely disperse any released refrigerant and preferably expel it externally into the atmosphere. 6-8 Checks to the refrigeraon equipment Where electrical components are being changed, they shall be t for the purpose and to the correct specicaon. At all mes 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 installaons using ammable refrigerants: - The charge size is in accordance with the room size within which the refrigerant containing parts are installed; - The venlaon machinery and outlets are operang adequately and are not obstructed; - If an indirect refrigerang circuit is being used, the secondary circuit shall be checked for the presence of refrigerant;42 - Marking to the equipment connues to be visible and legible. Markings and signs that are illegible shall be corrected; - Refrigeraon pipe or components are installed in a posion where they are unlikely to be exposed to any substance which may corrode refrigerant containing components, unless the components are constructed of materials which are inherently resistant to being corroded or are suitably protected against being so corroded. 6-9 Checks to electrical devices Repair and maintenance to electrical components shall include inial safety checks and component inspecon procedures. If a fault exists that could compromise safety, then no electrical supply shall be connected to the circuit unl it is sasfactory dealt with. if the fault cannot be corrected immediately but it is necessary to connue operaon, an adequate temporary soluon shall be used. This shall be reported to the owner of the equipment so all parts are advised. Inial safety checks shall include: - That capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking; - That there no live electrical components and wiring are exposed while charging, recovering or purging the system; - That there is connuity of earth bonding.

7. 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 electrical supply to equipment during servicing, then a permanently operang form of leak detecon shall be located at the most crical point to warn of a potenally hazardous situaon. Parcular aenon shall be paid to the following to ensure that by working on coelectrical components. The casing is not altered in such a way that the level of protecon is aected. This shall include damage to cables, excessive number of connecons, terminals not made to original specicaon, damage to seals, incorrect ng of glands, etc. Ensure that apparatus is mounted securely. Ensure that seals or sealing materials have not degraded such that they no longer serve the purpose of prevenng the ingress of ammable atmospheres. Replacement parts shall be in accordance with the manufacturer’s specicaons. NOTE: The use of silicon sealant may inhibit the eecveness of some types of leak detecon 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 inducve or capacitance loads to the circuit without ensuring that this will not exceed the permissible voltage and current permied for the equipment in use. Intrinsically safe components are the only types that can be worked on whilelive in the presence of a ammable atmosphere. The test apparatus shall be at the correct rang. Replace components onlywith parts specied by the manufacturer. Other parts may result in the ignion of refrigerant atmosphere from a leak.

Check that cabling will not be subject to wear, corrosion, excessive pressure, vibraon, sharp edges or any other43 adverse environmental eects.The check shall also take into account the eects of aging or connual vibraon from sources such as compressors or fans. 10.Detecon of ammable refrigerants Under no circumstances shall potenal sources of ignion be used in the searching for or detecon of refrigerant leaks. A halide torch (or any other detector using a naked ame) shall not be used. 11.Leak detecon methods The following leak detecon methods are deemed acceptable for systems containing ammable refrigerants: - Electronic leak detectors shall be used to detect ammable refrigerants, but the sensivity may not be adequate, or may need re-calibraon (Detecon equipment shall be calibrated in a refrigerant-free area.) - Ensure that the detector is not a potenal source of ignion and is suitable for the refrigerant used. - Leak detecon 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 detecon 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 pipe-work. - If a leak is suspected, all naked ames shall be removed/ exnguished. - If a leakage of refrigerant is found which requires brazing, all of the refrigerant shall 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) shall then be purged through the system both before and during the brazing process. 12.Removal and evacuaon - When breaking into the refrigerant circuit to make repairs - or for any other purpose convenonal procedures shall be used. However, it is important that best pracce is followed since ammability is a consideraon. 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 cung 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 mes. Compressed air or oxygen shall not be used for this task. Flushing shall be achieved by breaking to ll unl the working pressure is achieved, then venng to atmosphere, and nally pulling down to a vacuum. This process shall be repeated unl no refrigerant is within the system. When the nal charge is used, the system shall be vented down to atmospheric pressure to enable work. This operaon is absolutely vital if brazing operaons, on the pipe-work are to take place. Ensure that the outlet for the vacuum pump is not close to any ignion sources and there is the vacuum in the system with OFN and connuing venlaon available. 13.Charging procedures In addion to convenonal charging procedures, the following requirements shall be followed: - Ensure that contaminaon of dierent refrigerants does not occur when using charging equipment.44 - 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 refrigeraon system is earthed prior to charging the system with refrigerant. - Label the system when charging is complete (if not already). - Extreme care shall be taken not to overll the refrigeraon system. Prior to recharging the system it shall be pressure tested with OFN. The system shall be leak tested on compleon of charging but prior to commissioning. A follow up leak test shall be carried out prior to leaving the site. 14.Decommissioning Before carrying out this procedure, it is essenal that the technician is completely familiar with the equipment and all its detail. It is recommended good pracce that all refrigerants are recovered safely. Prior to the task being carried out, an oil and refrigerant sample shall be taken in case analysis is required prior to re-use of reclaimed refrigerant. It is essenal that electrical power is available before the task is commenced. a. Become familiar with the equipment and its operaon. b. Isolate system electrically. c. Before aempng the procedure ensure that: - Mechanical handling equipment is available, if required, for handling refrigerant cylinders; - All personal protecve equipment is available and being used correctly; - The recovery process is supervised at all mes by a competent person; - Recovery equipment and cylinders conform to the appropriate standards. d. Pump down refrigerant system, if possible. e. If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system. f. Make sure that cylinder is situated on the scales before recovery takes place. g. Start the recovery machine and operate in accordance with manufacturer’s instrucons. h. Do not overll 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 completed, make sure that the cylinders and the equipment are removed from site promptly and all isolaon valves on the equipment are closed o. k. Recovered refrigerant shall not be charged into another refrigeraon system unless it has been cleaned and checked. 15.Labelling Equipment shall be labelled stang that it has been de-commissioned and emped of refrigerant. The label shall be dated and signed. Ensure that there are labels on the equipment stang the equipment contains ammable refrigerant. 16.Recovery When removing refrigerant from a system, either for servicing or decommissioning, it is recommended good pracce 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 cylinders45 for the recovery of refrigerant). Cylinders shall be complete with pressure relief valve and associated shuto 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 instrucons concerning the equipment that is at hand and shall be suitable for the recovery of ammable refrigerants. In addion, 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 condion. Before using the recovery machine, check that it is in sasfactory working order, has been properly maintained and that any associated electrical components are sealed to prevent ignion 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 evacuaon process shall be carried out prior to returning the compressor to the suppliers. Only electric heang to the compressor body shall be employed to accelerate this process. When oil is drained from a system, it shall be carried out safely. When moving or relocang the air condioner, consult experienced service technicians for disconnecon and reinstallaon of the unit. Do not place any other electrical products or household belongings under indoor unit or outdoor unit. Condensaon dripping from the unit might get them wet, and may cause damage or malfuncon of your property. To keep venlaon openings clear of obstrucon. The appliance shall be stored in a well-venlated area where the room size corresponds to the room area as specied for operaon. The appliance shall be stored in a room without connuously operang open ames (for example an operang gas appliance) and ignion sources (for example an operang electric heater). Reusable mechanical connectors and ared joints are not allowed.S FE U R I GTHE E
