Application range
2.4.1 Qualified refrigerants and oils
IMPORTANT
It is essential that the glide of refrigerant blends (primarily R407A and R407F)
be carefully considered when adjusting pressure and superheat controls.

2.4.3 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
configuration a minimum stable superheat of at least 5K is required.
