Handling refrigerant safely

Maintenance must not be carried out on the vehicle air conditioner when
the engine is at operating temperature.
When performing maintenance on the vehicle air conditioner the surface
temperature of attachment parts or surrounding parts must be less than
405 °C.
Wear personal safety equipment (safety goggles and protective gloves)
and avoid coming into contact with the refrigerant. Contact with the refrig-
erant draws out body heat and the affected areas can freeze.
Make sure that refrigerant is not able to escape and leak into the environ-
ment during operation, when filling or draining refrigerant or during repair
and service work.
This adheres to environmental protection laws. It also avoids the difficulty
or impossibility of detecting leaks in the vehicle or in the unit due to the
presence of refrigerant in the vicinity of the unit.
Do not inhale refrigerant vapour. Although the vapour is non-toxic, it
displaces the oxygen you need to breathe.
Refrigerant must not be used in low-lying spaces such as assembly pits
or soakaways. Refrigerant is heavier than oxygen and therefore dis-
places the air you need to breathe. This can cause a lack of oxygen when
working in unventilated assembly pits.
Take suitable precautions to ensure that leaking refrigerant is not able to
get into the drainage system.
Special information on refrigerant R-1234yf and safety measures as well
as protecting personnel and objects, including fire protection can be
found in the safety sheets of the refrigerant manufacturer.
