Safety
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.
2.4 Operational measures when using the unit
The operator must provide operating instructions according to TRG 402
for each filling system (AirConServiceCenter). These operating instruc-
tions must be used to train personnel in handling the unit.
The operator must ensure that personnel are instructed in the following
points at least once a year:
 Special dangers when dealing with compressed gases
 Safety guidelines when dealing with compressed gases
 Health precautions when dealing with compressed gases
 Operating the unit and performing service work on the unit
The operator must ensure that personnel appointed to perform service
and repair work as well as leak inspections are certified to deal with refrig-
erant and filling systems.
