BOM Variation

The BOM (bill of material) marking at the end of the compressor designation indicates the different
compressor layouts and details. YF*K1E compressor models are available in the f ollowing BOM
versions:
Suction and discharge

Application range

2.4.1 Qualified refrigerants and oils

IMPORTANT
Some ref rigerant blends have a significant temperature glide. It is essential
that the glide of the refrigerant blends be carefully considered when adjusting
pressure and superheat controls.
IMPORTANT
Ref rigerant blends with low GWP containing HFO's have a low chemical
stability in presence of air or humidity. The same levels of cleanliness, dryness
and evacuation of the ref rigerant circuit are required as in HFC & POE
applications, including the use of filter dryers.

Oil recharge values can be taken from the compressor nameplate or from Copeland Select software,
which can be downloaded from www.climate.emerson.com/en-gb/tools-resources.
NOTE: For systems using A1 refrigerants (R404A, R407A, R407F, R448A or R449A) the
flammable refrigerant sticker is not of application and can be removed from the compressor.

2.4.2 Application limits

CAUTION
Inadequate lubrication! Compressor breakdown! The superheat at the
compressor suction inlet must always be sufficient to ensure that no refrigerant
droplets enter the compressor. For a typical evaporator-expansion valve
conf iguration a minimum stable superheat of at least 5 K is required.
For application envelopes and technical data, please refer to Copeland Select software available at
www.climate.emerson.com/en-gb/tools-resources.
