3.3 Use of flammable refrigerants of the A2L
safety group
Information
The information in this chapter about the use of
refrigerants of the A2L safety group refer to
European regulations and directives. In regions
outside the EU, observe the local regulations.
This chapter describes the additional residual risks
posed by the condensing compressor when using A2L
safety class refrigerants and provides explanations.
This information helps the system manufacturer carry
out the required risk assessment. The information

Risk of air penetration during operation in the
vacuum range
NOTICE
!
!
Potential chemical reactions as well as in-
creased condensing pressure and rise in dis-
charge gas temperature.
Avoid air penetration!
WARNING
A critical shift of the refrigerant ignition limit is
possible.
Avoid air penetration!

3.1 Name plate

The name plate is attached to each compressor hous-
ing and contains relevant information like serial num-
ber, LRA and max. operating amperage, oil type and
charge, etc. Additionally, it contains the relevant ap-
proval marks, and BITZER QR code that may be used
to ensure that the compressor is an authentic BITZER
compressor.

alone can in no way replace the risk assessment for the
system.
Design, maintenance and operation of refrigeration sys-
tems using flammable refrigerants of the A2L safety
class are subject to particular safety regulations.
When installed in accordance with these operating in-
structions and under normal operating conditions
without malfunction, the compressors are free from ig-
nition sources that could ignite the flammable refriger-
ants of the A2L safety class. They are considered tech-
nically tight. The compressors are not designed for op-
eration in an Ex zone. The compressors have not been
tested for use with flammable refrigerants in applica-
