AGL_Stream_ST_A2L_A1_4M_6M_EN_Rev00
The Stream compressors have been modified internally to support operation with A2L refrigerants.
The modified models are identified by the generation or index number "2" in the nomenclature. Only
compressors marked with index number "2" are approved for operation with A2L refrigerants. The
compressor models with index number "1" are not suitable and not approved for operation with A2L
refrigerants and can only be operated with A1 refrigerants. The compressors with index number "2"
are qualified for both refrigerant groups and can be used alternatively with A2L and A1 refrigerants.
The qualification and suitability for A2L operation and the changeover to index number "2" in
the compressor nomenclature are of application from serial number 21J7611M
(October 1
st
, 2021) onwards.
2.3 Nameplate information
All important information for identification of the compressor is printed on the nameplate located
below the compressor oil pump. The type of refrigerant used should be stamped on the nameplate
by the installer.

The year and month of production are shown as part of the serial number (Jan
= A, Feb = B, … Dec
= L). Example: the serial number
21H
18110 M indicates a compressor manufactured in August
2021.
2.4 Application range
2.4.1 Qualified refrigerants and oils
IMPORTANT
Some refrigerant blends have a significant temperature glide. It is essential
that this glide be carefully considered when adjusting pressure and superheat
controls.
NOTE: R454C, R455A and R454A are classified as A2L (mildly flammable) refrigerants.
NOTE: For systems using A1 refrigerants (R448A, R449A, R407A, R407F, R404A, R407C, R513A,
R450A, R134a or R22
) the flammable refrigerant sticker is not of application and can be
removed from the compressor.
