3.1 Use of flammable refrigerants of the A2L safety
group (e.g. R1234yf)
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.
Information
For refrigerants of the A3 safety group, e.g.
R290 propane or R1270 propylene, specific
compressor designs can be delivered upon re-
quest. In this case, also observe the additional
Operating Instructions.
This chapter describes and gives explanations to the
additional residual risks originating from the com-
pressor when using refrigerants of the A2L safety
group. This information helps the manufacturer of the
system to make the risk assessment for the system.
This information may in no way replace the risk assess-
ment for the system.
Design, maintenance and operation of refrigeration sys-
tems using refrigerants of the A2L safety group are
subject to particular safety regulations.
When installed according to these Operating Instruc-
tions and in normal operation conditions without mal-
functions, the compressors are free from ignition
sources that could ignite the flammable refrigerants
R1234yf and R1234ze(E). They are considered as
technically tight. No ignition source assessment is
available for other refrigerants of the A2L safety group.
