Air conditioning systems with refrigeranR1234yf - General information - Edition 07.2017
Risk of freezing injury from refrigeran
When working on the air conditioning system, there is a risk of
highly pressurised refrigeranescaping from the system. There is
a risk of injury to the skin and parts of the body due to freezing.
– Wear protective gloves.
– Wear protective goggles.
– Extract refrigeranand open the refrigerancircuiimmediately
afterwards.
– If more than 10 minutes have passed since the refrigeranwas
extracted, repeathe extraction process before opening the
refrigerancircuit. Pressure could build up in the refrigeran
circuifrom continued evaporation.

Safety measures when working on vehicles with a start/stop system
Risk of injury due to unexpected motor star
lk
If the vehicle’s start/stop system is activated, the engine can star
unexpectedly. A message in the dash panel inserindicates
whether the start/stop system is activated.
– Deactivate start/stop system by switching off the ignition.

Safety measures when using air condi‐
tioner service stations
•
•
Before connecting the charging system to the air conditioner,
make sure thaall existing shut-off valves are closed.
Before the air conditioner service station is decoupled from the
air conditioning system, ensure thathe process is complete.
This will prevenany more refrigeranthan necessary and
technically unavoidable from entering the atmosphere.
•
Once the purified refrigeranfrom the air conditioner service
station /extraction system has been filled into an external com‐
pressed-gas cylinder, close the hand shut-off valves athe
cylinder and charging system.
•
•
•
Do noexpose the air conditioner service station , extracting
and charging system to moisture and do nouse in a damp
environment.
Before performing any maintenance work on the air condition‐
er service station , disconnecthe extracting and charging
system from the power supply.
To reduce the risk of fire, avoid using an extension cable. If
the use an extension cable is unavoidable, use an extension
2
cable with a cross-section of aleas2.5 mm .
•
•
In case of fire, remove external cylinder.
If oil is drawn ouof the air conditioning system by the suction
accumulator of the air conditioner service station and emptied
into the supplied measuring beaker, ensure thaiis poured
into a sealable container afterwards as the oil could contain a
small amounof refrigerant. Refrigeranmusnobe released
into the environment.
