Draw off A/C system if this temperature is not reached. Measure amount of refrigerant drawn off. See 64 50 009 DRAWING OFF, EVACUATING AND FILLING A/C SYSTEM (R 134A) .

If drawn-off quantity does not correspond to specified fill quantity : supplement refrigerant and repeat test. See HEATING AND AIR CONDITIONING - TECHNICAL DATA .

If fill quantity is correct, continue troubleshooting by pressure measurement.

64 50 ... INSTRUCTIONS FOR HANDLING REFRIGERANT R 134A

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 (< or = 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. Rinse affected body parts 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 replaced as excessive moisture may have entered the system. See .

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 (CO2), extinguishant powder and a sprayed water jet are deemed to be suitable extinguishants. Cool reservoirs at risk with a sprayed water jet (risk of bursting!).

64 50 ... INSTRUCTIONS FOR HANDLING REFRIGERANT OIL (FOR REFRIGERANT R 134A)

Action to be taken after contact with refrigerant oil

1. After contact with eyes, rinse thoroughly with plenty of water and take out contact lenses (if worn). Then seek immediate medical attention.
2. After contact with the skin, wash body parts affected with plenty of soap and water.
3. Do not induce vomiting if oil is swallowed, seek immediate medical attention.
4. If inhaled, introduce the person affected to fresh air. Seek medical attention if problems persist.

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 ... LEAK TESTING WITH ULTRAVIOLET ADDITIVES (UV ADDITIVES) (BMW LEAK-TESTING CASE)

Note. Fill the hose system of the hand pump completely with UV additive PRIOR to use Use the UV additive exclusively for BMW-approved refrigerant oils Do not operate the A/C system while the hand pump is connected or in use The A/C system must always be filled with an adequate amount of refrigerant to enable the leak-detecting agent to be properly distributed

Necessary preliminary tasks

Before actually testing for leaks, check the entire refrigerant circuit using the UV leak-detecting lamp to ensure that no AV additive is already in the area of the refrigerant circuit.

If already illuminated areas are found, carefully clean the area in question with the cleaning agent contained in the case.

On initial use

Connect hand pump (1) to additive cartridge (2) and hose piece (3).

Scheme 105

On initial use

2. Skin contact: In the event of contact with skin, remove affected clothing immediately and rinse with plenty of water.
3. After inhalation: If refrigerant vapors are inhaled in greater concentrations, remove the person affected to an area of fresh air and keep them under supervision. Consult a doctor. If breathing problems are experienced, breathe additional oxygen. If the person affected is breathing with difficulty or has stopped breathing, incline the person's head at the neck and administer the kiss of life.

64 50 009 DRAWING OFF, EVACUATING AND FILLING A/C SYSTEM (R 134A)

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 (800-1200 RPM) and with A/C system turned on for a few minutes.

The limits the entertainment 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.

Follow instructions for opening and replacing parts in refrigerant circuit!

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.

64 52 ... INSTRUCTIONS FOR COMPRESSOR REPLACEMENT

When evacuating the air-conditioning system, refrigerant oil is also extracted and collected in the oil separator of the service station.

After evacuation, the refrigerant must be filtered in the service station as the oil separator could still contain a liquid refrigerant/oil mixture. The filtering process gasifies the refrigerant completely and only the previously bound refrigerant oil remains in the oil separator. Measure and note down this quantity of refrigerant oil, refer to EVACUATING A/C SYSTEM .

Scheme 125

Transfer the refrigerant oil remaining in the previous compressor via the filler plug completely into a measuring container.

Scheme 126

Measure the amount of refrigerant oil collected from the previous compressor.

Scheme 127

The new compressor is filled at the factory with refrigerant oil.

Open filler plug and pour entire contents of compressor into a clean container.

Installation

Replace sealing ring and moisten with refrigerant oil.

Tightening torque. See HEATING AND AIR CONDITIONING - TIGHTENING TORQUES .

Scheme 128

From the new compressor, pour the same amount of refrigerant oil (as drained from the previous compressor) + 10 g extra into a clean measuring container and pour again into the new compressor.

Remaining refrigerant oil can be poured into service station tank, refer to EVACUATING A/C SYSTEM .

Otherwise the excess refrigerant oil must be disposed of correctly.

On account of its hygroscopic properties, refrigerant oil must not be stored in open containers.

Scheme 129

The refrigerant oil drawn off from the oil separator of the service station and from the previous compressor must not be reused and must be correctly disposed of.

Scheme 130

After installing the new compressor, it is essential before filling the A/C system to pour the same amount of the previously drawn off refrigerant oil into the system again, refer to EVACUATING A/C SYSTEM .
