7 3.1.2 Precautions For Operators Safety GENERAL PRECAUTIONS All the operators shall not be under the effect of tranquillizers, drugs or alcohol when performing their job Before starting their job, operators shall be perfectly aware of the position and operation of all the controls indicated on the use manual. Always pay attention to any danger sign affixed on the installation and within the company of the user. The employer is responsible for the spreading of this document to the whole personnel that is going to work on the equipment. Besides the obligation to strictly comply with the instructions contained in this manual, the operators shall inform their heads on any deficiency or potentially dangerous situation that might occur. In case of machine malfunctioning, check the procedures outlined in the various chapters. Always refer to the safety standards adopted by the company employing the equipment with a view to avoiding useless risks. ENGLISH 7 / 75 CAP. 3 - SAFETY CONDITIONS

8 RISK OF ASPHYXIA GASOLINE ENGINES Exhaust gases of gasoline vehicles contain carbon monoxide, a colourless and odourless gas which, if inhaled, can cause serious physical problems. Special attention is always required when working within pits, as exhaust gases components are heavier than air and consequently deposit on the bottom of the pit. Attention shall be paid to natural gas vehicles as well. DIESEL ENGINES Diesel engine exhaust gas composition is not always the same. It can change according to: type of engine, intake, conditions of use and fuel composition. Diesel exhaust is made up of gases (CO, CO 2, NO X and HC) and particulate (soot, sulphates, etc.); the small particles of carbon making up soot remain suspended in the air and can thus be breathed. Toxic components, albeit in small quantities, are present as well. SAFETY MEASURES: - Always ensure good ventilation and air aspiration (especially in the pits). - In closed premises, always start the exhaust gas aspiration system. RISK OF SMASHING If the vehicles are not correctly secured by means of mechanic devices, the operator might get smashed against a working bench or against a wall. Even the equipment placed on unstable supports might fall and squash the operator s limbs. SAFETY MEASURES: - Make sure the vehicle has been secured by pulling the hand brake and locking the wheels. - Make sure the equipment has been positioned on a stable support and, in case of trolley, that its wheels have been locked before use. CAP. 3 - INDEX 8 / 75 ENGLISH

9 RISK OF INJURY Engines, both working and in standstill, include moving parts (belts or other parts) which might injure hands and arms. In the vehicles, the cooling fan starts automatically by means of a temperature sensor even when the engine is off; always pay attention when operating close to it and disconnect it if needed. SAFETY MEASURES: - When the engine is turned on, do not put hands into the moving parts area. - When operating close to electrically started fans, let the engine cool down beforehand and then remove the fan plug from the engine. - Keep the testing tools connection cables far from the engine moving parts. RISK OF BURN When intervening on the engine, protect face, hands and feet with suitable protective devices, avoid contact with hot surfaces, such as sparking plugs, radiators, pipings of the cooling system and electromechanic sensors. Catalytic mufflers reach extremely high temperatures and can cause burns or fires. Attentions shall thus be paid to avoid touching these objects without suitable precautions. SAFETY MEASURES: - Wear protective gloves. - Let cool down the engine and other independent accessories, if any. - Do not install testing tools connection cables over or close to hot parts - Do not keep the engine turned on once checks have been completed. ENGLISH 9 / 75 CAP. 3 - SAFETY CONDITIONS

10 RISK OF FIRE OR EXPLOSION When carrying out operations on the fuel system (injectors, fuel and gasoline pump, etc.) there is risk of fire or explosion due to the fuels employed and/or vapours formed by them. SAFETY MEASURES: - Disable start. - Let the engine cool down. - Do not use free flames or sparks sources. - Do not smoke. - Collect the outflowing fuel. - Start the aspiration units in closed premises. RISK RELATING TO NOISE LEVEL During measurements on the vehicle, noise levels can exceed 90dB. Such noise levels can be reached with ultrasonic cleaning or with the vehicle s engine high rpm. If a person is exposed to such noise sources for a long period of time, this can cause irreversible hearing damage. SAFETY MEASURES: - The operator shall adopt personal protective equipment (safety ear muffs). - The operator shall also protect from noise the working stations close to the areas where test on the vehicle. CAP. 3 - INDEX 10 / 75 ENGLISH

11 RISK RELATING TO DANGEROUS VOLTAGE Civil or industrial electric power distributions, as well as vehicles electric systems, do imply dangerous voltages. When an operator is in contact with testing tools or live parts of the engine, risk of electrocution exists. For instance, this might be caused by cables with damaged insulation (ex. Bites of animals on power cords). This is especially true of the vehicle starting system and testing tools connections. SAFETY MEASURES: - Connect the testing tools to an electric socket safety relay and correctly grounded. - For the testing tool connection, use exclusively the cables provided with the tool itself, making sure insulation is not damaged. - Make sure the testing tool is grounded before turning it on. - When carrying out interventions on the electrical system of a vehicle (connection of testing tool, replacement of starting system parts), supply voltage shall be unplugged (ex. battery). - During checks and setting operations with the engine turned on, attention shall be paid to avoid touching those vehicle live components (for instance the starting system) without the suitable precautions (for instance insulating gloves). RISK OF INTOXICATION The pipes that are used for exhaust gases sampling if subject to high temperatures (exceeding 250 C or due to fires) release a highly toxic gas which, in case of inhalation, can be harmful for health. SAFETY MEASURES: - In case of inhalation, immediately contact a doctor. - To remove combustion residues wear neoprene or PVC gloves. - Fire residues can be neutralized with a calcium hydroxide solution. This leads to the formation of calcium fluoride that can be removed with water. ENGLISH 11 / 75 CAP. 3 - SAFETY CONDITIONS

12 3.2 IMPORTANT INFORMATION ON TOOL SAFETY When using the tool, the following operations are not allowed as they might cause, under certain circumstances, danger for persons and cause permanent damage to the tool itself. - Do not remove or make unreadable labels, signs and/or dangers signs placed on the tool and in the area nearby. - Do not disable the machine safety devices - Use exclusively original fuses with the required ampere capacity! In case of electric supply anomalies, the machine shall be powered off immediately. Defective fuses shall not be repaired or excluded but replaced with fuses of the same type. - The machine electrical connections shall be inspected at regular intervals. Defects, such as slackened connections or burnt cables or cables with damaged insulation, shall be immediately removed and replaced. - Non authorized personnel must not open the equipment. Within the tool there are parts that, if touched, can cause electrocution: power off before opening the tool to carry out repair operations. CAP. 3 - INDEX 12 / 75 ENGLISH

13 3.3 GENERAL INSTRUCTIONS Pressure equipment undergoes checks before commissioning and periodical checks during operation in compliance with rules and law provisions in force in the country where the tool is used. The operator shall be responsible for the UNIT use in compliance with rules in force in their country. The UNIT is a tool designed for recovery and recycling of R134a refrigerant of A/C systems of cars. This unit is to be used exclusively by duly trained operators having a good knowledge on cooling, cooling systems, refrigerants and possible damages caused by pressure equipment. The careful reading of this manual by the user is necessary for the correct and safe use of the unit. The user shall not be entitled to open the Unit since maintenance operations are reserved to the authorised service center. PERSONAL SAFETY: Use coolant R134a only. The mixture with other types of coolant causes sever damage to the A/C and cooling systems and to the service equipment. It is advisable to wear suitable protections such as goggles and gloves; the contact with the coolant may cause blindness and other body injuries to the operator. Avoid the contact with skin; the low boiling temperature (about 30 C) may cause burns. Avoid inhaling of the coolant fumes. Do not expose it to the direct sunbeams and rain. Use the station in ventilated rooms. Do not smoke near the station and during the operations. Use the station clear of heat sources, open flames and/or sparks. Further medical and safety information may be obtained from the lubricants and coolants producers. CLIMA-8500 EVO SAFETY: Before carrying out connections between the unit and a A/C system or external tank, be sure that all the valves are closed. Before disconnecting the unit, be sure that the phase is completed and all the valves are closed so that the coolant is not dispersed in the atmosphere. Do not change the calibration of the safety valves and control systems. Do not use external tanks or other storage containers that are not homologated or without safety valves. Do not leave the unit live unless it is used in the near future; cut off the power supply before a long period of inactivity of the unit. The unit shall have to be always attended. The unit shall have not to be used in an explosion-risk environment. ENGLISH 13 / 75 CAP. 3 - SAFETY CONDITIONS

14 HOSES: Hoses may contain coolant under pressure. Always connect the CLIMA-8500 EVO hoses with quick coupler of RED color on the HP side (high pressure) of the A/C system. Always connect the CLIMA-8500 EVO hoses of BLUE color on the LP side (low pressure) of the A/C system. Disconnect the hoses with extreme caution. COOLANT: The car service equipment and A/C systems containing R134a should not be tested using compressed air. Some mixtures of air and HCF 134a showed to be inflammable at high pressures. These mixtures are potentially hazardous and show fire and explosion risks that may cause both personal and material damage. Check the type of coolant used by the A/C system on the vehicle use book. WORKING ENVIRONMENT: The unit must operate in open places or rooms with a good ventilation (at least 4 changes of air per hour). Work away from open flames and hot surfaces; the coolant breaks down at high temperatures releasing toxic and aggressive substances which are harmful to both the operator and the environment. Avoid inhaling the system coolants and oils. The exposure may irritate both the eyes and the respiratory tract. OPERATING CONDITIONS: do not expose to and do not use the unit in case of rain or other adverse weather conditions. STOP FOR LONG PERIOD: The unit shall be stored in a safe place, disconnected from the electric network, sheltered from excessive temperatures, humidity and risk of collision with objects that may damage it. Be sure that the valves on the internal tank are closed. For making the unit operate again follow the activation process only after opening the internal tank valves again.

19 4.4 GUIDELINES FOR THE HANDLING OF REFRIGERANT Precautions for refrigerant storage The Refrigerant to be removed from a system has to be carefully handled so as to prevent or minimize mixing of several refrigerants. The unit is specially reserved to the use of refrigerant R134a. Vessels used for storage of refrigerants shall be dedicated to each specific refrigerant to prevent mixing of several refrigerants. Vessels shall be free from oil or other contaminants and clearly marked so as to identify the refrigerant contained. WARNING: For handling, use and storage of Refrigerant R134a, ask the refrigerant supplier for the technical and safety data sheets and comply with their requirements Conditions of refrigerant and system Life and age of the system can be of relevance to decide whether to recycle the refrigerant from a system. Installation procedures and maintenance interventions carried out during the system life have a remarkable effect on the refrigerant quality. Systems which have not been duly cleaned or drained might have high levels of contamination in the refrigerant and oil. If the life of the system is not known, the recovered refrigerant has to be at least recycled before being recharged into the system. In case the operators are not sure on the refrigerant contamination level, preliminary checks can be carried out by means of a special kit for acidity and humidity measurement. ENGLISH USE 19 / 75 CAP. 4 - MANUAL STRUCTURE AND

20 4.4.3 Recycling capacity Filtering systems of the recycling unit have to be replaced regularly to preserve the recycling equipment performance. However, even if all elements indicate there is no need to recycle the refrigerant, recycling has to be carried out in any case. Before recharging refrigerant gas into the system the latter has to be cleaned and drained. Procedures indicated in this manual have to be complied with to ensure the system is free from contamination before charging the refrigerant into the system. Units have to be cleaned and serviced on a regular basis, notably in case they have been used with highly contaminated refrigerant: it is very important to prevent contamination from the previous operation from affecting next operations.

45 CAP A/C SYSTEM RECHARGE 11.1 Preliminary operations The recovery and recharge operations have be carried out after the car /AC system has run for some time; however, an excessively hot A/C system has to be avoided since the next recharge phase could be adversely affected by high pressures. The recharge station has to be ON. No special pre-arrangement is required: connecting hoses have to be attached by identifying their position. Then connect HP and LP quick couplers (or the single coupler, depending on the type of system). After quick couplers connection the knob has to be screwed. Details necessary for the performance of the charge/recovery/vacuum cycle are the amount of refrigerant and of oil. These data are often found on the engine compartment plate or on the technical manuals of the garage. As to oil quantity technical manuals of cars, systems as well as available details in general indicate the total quantity of oil in the system. Indeed the amount of oil to be recharged is that extracted during the refrigerant recovery phase which is very small Non condensable Gases Discharge The non condensable gases discharge solenoid valve shall have to be enabled if air is present into the vessel and can be activated from the keypad in the maintenance menu. The air presence into the vessel can be detected only after the machine has been at rest for a certain period (as for instance during the morning). Read the pressure measurement shown on the vessel gauge to check the air presence and check if the vessel pressure value on the LP gauge ( C) scale corresponds to the temperature marked on the scale: if it proves to be significantly higher than ambient temperature, then some air is likely to be inside the vessel. ENGLISH 45 / 75 CAP A/C SYSTEM RECHARGE

46 11.3 Zero Tolerance Mode CLIMA-8500 EVO can apply two different refrigerant recharge modes; the first one is called Quick mode and features the opening of the recharge valve by injecting gas through the HP port. By the Quick Mode part of the refrigerant remains into the hoses and is compensated by software calculation. Whenever the recharge is not completed the UNIT shifts automatically to the Zero Tolerance mode. The Zero Tolerance function is the second recharge procedure, an alternative to the Quick Mode. It features a more accurate recharge and guarantees a successful recharge (it however requires a longer time and the operator s intervention). If the car A/C system is equipped with both couplers or with LP coupler only, there are two slightly different working modes; in any case if only the HP coupler is available the Zero Tolerance mode is not applicable. With both HP and LP couplers available the Zero Tolerance features the injection of the selected refrigerant amount into the system through the HP hose; then refrigerant remained into the HP hose is sucked by the car system engine and compressor running through LP (after disconnecting and closing the HP coupler). In case the LP coupler only is available the station charges the system with 50% of the selected amount with car compressor off and waits for 10 minutes before recalling the operator. This wait time quite rare since most of cars are equipped with HP coupler too allows the refrigerant injected near the compressor that is LP side to evaporate to prevent any damage to the compressor during the admission of liquid phase refrigerant. Then, after car and A/C system switch ON recharge continues through timed injection of refrigerant through hose LP, such injections start exclusively if the LP pressure is lower than 3 bar.

56 13.7 Flushing Phase It is advisable to perform the system washing phase (Flushing) after a certain number of recharging cycles or after replacing any components or parts of the A/C system of a vehicle. The system washing (Flushing) consists in purifying the vehicle cooling system through several R134a gas flushes, by recovering it each time, so that the impurities can be filtered little by little through the additional dryer filter. Thanks to its specific design, CLIMA-8500 EVO can automatically manage the flushing process so that the process becomes fully automatic. In order to carry out the washing, the operator has to separately buy a specific kit; this kit is a necessary tool because in every A/C system there are parts that shall not have to undergo the washing, such as the flow-restriction valve and the internal compressor, that could otherwise be damaged by it. Once that you have installed the flushing kit, in the MANUAL CYCLES menu position on FLUSHING through the keys then push to start the phase. You can set the flushing time by pushing.
