Draw Off A/C system if this temperature is not reached. Measure amount of refrigerant drawn off.
If drawn-off quantity does not correspond to specified fill quantity: replenish refrigerant. See HEATING AND AIR CONDITIONING - TECHNICAL DATA .
If refrigerant quantity is correct fill A/C system.
Note. A/C systems with uncontrolled compressors only: If necessary, then continue troubleshooting by pressure measurement.
64 50... Leak-testing with leak tester device
| WARNING | Avoid contact with refrigerant. Follow Safety Precautions When Handling Refrigerant . |
Carry out leak-testing with a leak tester device from the workshop equipment catalog following the device manufacturer's operating instructions.
If leaks not to be localized are already identified during evacuation, the A/C system must nevertheless be filled. Then test for leaks with leak tester device.
Note. Refrigerant is heavier than air. Therefore always conduct the leak test below the lines and components to be tested. Shield lines and components against strong blasts of air (wind, drawing off).
Tighten down loose lines, mark leaks.
Then draw off draw off A/C system and seal off or repair leakage points.
Then refill A/C system and test for leaks.
64 50... Safety instructions for handling refrigerant R 134a
| WARNING | Although R 134a at normal temperature is non-toxic, non-flammable and not explosive in air in any mixture ratio, it is still essential to follow various safety precautions. |
The filled refrigerant circuit of the A/C system is subject to gauge pressure. When carrying out repairs on the A/C system, it is absolutely essential to draw off the refrigerant.
Do not weld or solder on filled A/C systems or in rooms into which R 134a may have leaked. Exposure to flames or high temperatures (50°C) may give rise to toxic decomposition products (fluorine gas). For this reason, do not smoke either.
R 134a must be drawn off, cleaned and returned to the A/C system with a service station following the relevant operating instructions.
Avoid all contact with liquid or gaseous R 134a. Wear protective goggles and gloves when working on the refrigerant circuit. R 134a acting on the skin can cause frostbite. Wash off thoroughly with cold water. If R 134a gets into your eyes, likewise rinse with plenty of water and, if necessary, remove contact lenses if worn. Then seek immediate medical attention. Likewise seek immediate medical attention if you experience problems after inhaling R 134a fumes.
As a gas, R 134a is colorless, odorless and heavier than air. If it gets into the atmosphere, this may result especially in workshop pits in an imperceptible danger of asphyxiation or in cardiac palpitations. Ventilate rooms adequately; if necessary, turn on installed extractor systems.
For a properly functioning A/C system, it is essential to have the greatest possible levels of cleanliness when working on the A/C system and the best possible evacuation (at least 30 minutes dehumidification from refrigerant circuit) before each filling of the A/C system.
R 134a absorbs moisture very easily. Therefore seal off opened pipes, condenser, evaporator, compressor and drier bottle immediately with plugs.
With replacement parts, the plugs may only be removed immediately before the lines are connected.
In the event of warranty claims, the old parts must be provided with plugs to be able to determine the cause of the damage.
If an A/C system has been completely drained by leakage, accident or repair, the drier element must be replace as excessive moisture may have entered the system.
Store filled pressurized refrigerant bottles in such a way that they are not exposed to direct sunlight or other heat sources (max. 45°C). Also avoid exposing them to mechanical stress (e.g. by dropping).
In the event of fire, carbon dioxide, extinguisher powder and a sprayed water jet are deemed to be suitable extinguishants. Cool reservoirs at risk with a sprayed water jet (risk of bursting!).
| CAUTION | After each refill of an A/C system, check that protective caps of filling valves are hand-tight. They serve as additional seals. |
64 50... Safety precautions when handling refrigerant oil (for refrigerant R 134a)
| WARNING | Observe the following points when handling refrigerant oil: Wear protective goggles. Wear gloves made from impermeable plastic. Do not swallow. Do not inhale. Action to be taken after contact with refrigerant oil: After contact with eyes, rinse thoroughly with plenty of water and take out contact lenses (if worn). Then seek immediate medical attention. After contact with the skin, wash body parts affected with plenty of soap and water. Do not induce vomiting if oil is swallowed, seek immediate medical attention. If inhaled, introduce the person affected to fresh air. Seek medical attention if problems persist. |
| WARNING | Refrigerant oil is non-combustible and non-explosive at normal temperatures. In spite of this, the following precautions must be observed: Do not store in the vicinity of flames, heat sources or strongly oxidizing materials. Suitable extinguishants: carbon dioxide, dry extinguishant, foam. |
Recycling
Dispose of drawn-off refrigerant oil as hazardous waste.
Observe country-specific waste-disposal regulations.
Absorb escaping refrigerant oil with fluid-binding material.
Notify the relevant authorities if larger amounts of refrigerant oil are discharged into above-ground water supplies, drainage systems or subsoil.
64 50 009 Drawing off, evacuating and filling A/C system (R 134a)
| WARNING | Avoid contact with refrigerant and refrigerant oil. Follow safety instructions for handling refrigerant R 134a. Follow Safety Instructions For Handling Refrigerant Oil . |
| IMPORTANT | Risk of damage! |
Restart engine only when A/C system has been correctly filled.
Note. Draw off, evacuate and fill the A/C system in accordance with the operating instructions of the relevant service station.
E60 only
If necessary, to connect service station, use manufacturer's adapter for high-pressure connection (red).
Instructions for drawing off A/C system
To help separation of refrigerant and refrigerant oil, run engine at low speed (800 of 1200 RPM) and with A/C system turned on for a few minutes.
This limits the entrapment of refrigerant oil while it is drawn off.
Drawn-off refrigerant oil must be changed and reintroduced via the service station.
If at the end of the drawing-off procedure the service station moisture indicator shows that the drawn-off refrigerant is excessively moist, clean the refrigerant in accordance with the service station operating instructions.
Recycling
Dispose of drawn-off refrigerant oil as hazardous waste.
Observe country-specific waste-disposal regulations.
Instructions for evacuating off A/C system
The evacuation procedure removes all traces of ambient air, water vapor and any other gases present from the A/C system.
This enables subsequent system filling with refrigerant.
A decrease in the vacuum level indicates a leak in the refrigerant circuit.
Instructions for filling A/C system
Before filling with refrigerant, top up the refrigerant oil entrained during drawing off.
Depending on the type of component replaced on the A/C system, it may be necessary to top up the refrigerant oil, even if no measurable losses have occurred during drawing off. Read and comply with the A/C system manufacturer's notes in this regard and the operating instructions of the relevant service station.
Information on the required refrigerant fill quantity for the entire A/C system is contained on the rating plate (1) in the engine compartment.
If necessary, refer to HEATING AND AIR CONDITIONING - TECHNICAL DATA for fill quantities.
