PREVENTIVE MAINTENANCE - TO BE PERFORMED BY TRAINED SERVICE PROVIDERS ONLY - 1 of 7
WARNING! TURN OFF CASE BEFORE PERFORMING PREVENTIVE MAINTENANCE!
Maintenance and Service Notes
· All maintenance staff and others working in the local area shall be instructed on the nature of work being carried out. Work in confined spaces shall be avoided.
· The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician is aware of potentially toxic or flammable atmospheres. Ensure that the leak detection equipment being used is suitable for use with all applicable refrigerants, i.e., nonsparking, adequately sealed, or intrinsically safe.
· If any hot work is to be conducted on the refrigerating equipment or any associated parts, appropriate fire extinguishing equipment shall be available on hand. A dry chemical or CO2 fire extinguisher should be adjacent to the charging area.
· No person carrying out work in relation to a refrigerating system which involves exposing any pipe work shall use any sources of ignition in such a manner that it may lead to the risk of fire or explosion. All possible ignition sources, including cigarette smoking should be keep sufficiently far away from the site of installation, repairing, removing and disposal, during which refrigerant can possible be released to the surround space. Prior to work taking place, the area around the equipment shall be surveyed to make sure that there are no flammable hazards or ignition risks. "No Smoking" signs shall be displayed.
· Ensure that the area is in the open or that it is adequately ventilated before breaking into the system or conducting any hot work. A degree of ventilation shall continue during the period that the work is carried out. The ventilation should safely disperse any released refrigerant and preferably expel it externally into the atmosphere.
Checks to the refrigerating equipment · Where electrical components are being changed, they shall be fit for the purpose and to the correct
specification. At all times, the manufacturer's maintenance and service guidelines shall be followed. If in doubt, consult the manufacturer's technical department for assistance. · The following check shall be applied to installation using FLAMMABLE REFRIGERANTS:
a) the actual REFRIGERANT CHARGE is in accordance with the room size within which the refrigerant containing parts are installed;
b) the ventilation machinery and outlets are operating adequately and are not obstructed; c) if an indirect refrigeration circuit is being used, the secondary circuit shall be checked for the
presence of refrigerant; d) marking to the equipment continues to be visible and legible. Markings and signs that are illegi-
ble shall be corrected; e) refrigerating pipe or components are installed in a position where they are unlikely to be ex-
posed 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. Checks to electrical devices · Repair and maintenance to electrical components shall include initial safety checks and component inspection procedures. If a fault exists that could compromise safety, then no electrical supply shall be connected to the circuit until it is satisfactorily dealt with. If the fault cannot be corrected immediately but it is necessary to continue operation, an adequate temporary solution shall be used. This shall be reported to the owner of the equipment, so all parties are advised. · Initial safety checks shall include: a) that capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking; b) that no live electrical components and wiring are exposed while charging, recovering or purging the system; c) that there is continuity of earth bonding.
16
PREVENTIVE MAINTENANCE - TO BE PERFORMED BY TRAINED SERVICE PROVIDERS ONLY - 2 of 7
WARNING! TURN OFF CASE BEFORE PERFORMING PREVENTIVE MAINTENANCE!
Maintenance and Service Notes
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 covers, etc. If it is absolutely necessary to have an electrical supply to equipment during servicing, then a permanent opening form of leak detection shall be located at the most critical point to warn of a potentially hazardous situation. · Particular attention shall be paid to the following to ensure that by 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 cables, excessive number and connections, terminals not made to original specification, damage to seals, incorrect fitting of glands, etc. · Ensure that the apparatus is mounted securely. · Ensure that seals or sealing materials have not degraded to the point that they no longer serve the purpose of preventing the ingress of flammable atmospheres. Replacement parts shall be in accordance with the manufacturer's specifications. Repair to intrinsically safe components · Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will not exceed the permissible voltage and current permitted for the equipment in use. · Intrinsically safe components are the only types that can be worked on while live in the presence of a flammable atmosphere. The test apparatus shall be at the correct rating. · Replace components only with parts specified by the manufacturer. Other parts can result in the ignition of refrigerant in the atmosphere from a leak. · NOTE The use of silicon sealant can inhibit the effectiveness of some types of leak detection equipment. Intrinsically safe components do not have to be isolated prior to working on them. Cabling · Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges, or any other adverse environmental effects. The check shall also take into account the effects of aging or continual vibration from sources such as compressors or fans. Detection of flammable refrigerants · Under no circumstances shall potential sources of ignition be used in the searching for or detection of refrigerant leaks. A halide torch (or any other detector using a naked flame) shall not be used. · The following lead detection methods are deemed acceptable for all refrigerant systems. · Electronic leak detectors may be used to detect refrigerant leaks but, in the case of FLAMMABLE REFRIGERANTS the sensitivity might not be adequate, or might need recalibration. (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 confirmed. · Leak detection fluids are also suitable for use with most refrigerants but the use of detergents containing chlorine shall be avoided as the chlorine can react with the refrigerant and corrode the copper pipe -work. · NOTE examples of leak detection fluids are
-bubble method. -fluorescent method agents. · If a leak is suspected, all naked flames shall be removed/extinguished. · 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 off valves) in a part of the system remote from the leak. Removal of refrigerant shall be according to the removal and evacuation procedures below.
17
PREVENTIVE MAINTENANCE - TO BE PERFORMED BY TRAINED SERVICE PROVIDERS ONLY - 3 of 7
WARNING! TURN OFF CASE BEFORE PERFORMING PREVENTIVE MAINTENANCE!
Maintenance and Service Notes Removal and evacuation · When breaking into the refrigerant circuit to make repairs-or for any other purpose-conventional proce-
dures shall be used. However, for flammable refrigerants it is important that the best practice be followed, since flammability is a consideration. The following procedure shall be adhered to:
a) safely remove refrigerant following local and national regulations; b) purge the circuit with inert gas; c) evacuate (optional for A2L); d) purge with inert gas (optional for A2L); e) open the circuit by cutting or brazing. · The refrigerant change shall be recovered into the correct recovery cylinders if venting is not allowed by local and national codes. For appliances containing flammable refrigerants, the system shall be purged with oxygen-free nitrogen to render the appliance safe for flammable refrigerants. This process might need to be repeated several times. Compressed air or oxygen shall not be used for purging refrigerant systems. · For appliances containing flammable refrigerants, refrigerant purging shall be achieved by breaking the vacuum in the system with oxygen-free nitrogen and continuing to fill until the working pressure is achieved, then venting to atmosphere, and finally pulling down to a vacuum (optional for A2L). This process shall be repeated until no refrigerant is within the system (optional for A2L). When the final oxygen-free nitrogen change is used, the system shall be vented down to atmospheric pressure to enable work to take place. · Ensure that the outlet for the vacuum pump is not close to any potential ignition sources and that ventilation is available. Charging procedures · In addition to conventional charging procedures, the following requirements shall be followed. a) Ensure that contamination of different refrigerants does not occur when using charging equip-
ment. Hoses or lines shall be as short as possible to minimize the amount of refrigerant contained in them. b) Cylinders shall be kept in an appropriate position according to the instructions. c) Ensure that the REFRIGERATING SYSTEM is earthed prior to charging the system with refrigerant. d) Label the system when charging is complete (if not already). e) Extreme care shall be taken not to overfill the REFRIGERATING SYSTEM. · Prior to recharging the system.

WARNING! TURN OFF CASE BEFORE PERFORMING PREVENTIVE MAINTENANCE! Maintenance and Service Notes
Recovery · When removing refrigerant from a system, either for servicing or decommissioning, it is recommended
good practice 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 labeled for that refrigerant (i.e., special cylinders for the recovery of refrigerant). Cylinders shall be complete with pressurerelief valve and associated shut-off valve 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 instructions concerning the equipment that is at hand and shall be suitable for the recovery of all appropriate refrigerants including, when applicable, FLAMMABLE 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 coupling and 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 in the event of 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 FLAMMABLE 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 a system, it shall be carried out safely.
