Technical data

If leaks not to be localized are already identified during evacuation, the A/C system must nevertheless be filled.

Refer to 64 50 009 DRAWING OFF, EVACUATING AND FILLING A/C SYSTEM (R 134A). Then test

for leaks with leak tester device.

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. Refer to 64 50 009 DRAWING OFF,

EVACUATING AND FILLING A/C SYSTEM (R 134A).

Then refill A/C system and test for leaks. Refer to 64 50 009 DRAWING OFF, EVACUATING AND

FILLING A/C SYSTEM (R 134A).

64 50 ... SAFETY 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 (>/= 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.

NOTE: Refrigerant is heavier than air.

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.
