Pressures on A-side are maintained at approximately 2 bar (29 psi)
by "regulating" A/C compressor also at various engine speeds. However,
this applies only within the performance range of the A/C compressor; if
the performance limits of the A/C compressor are exceeded. Refer to
→ Chapter "Pressures, Checking". |

Note
In vehicles with A/C Compressor Regulator Valve -N280-, the pressure
is modified on the low pressure side by the valve. |
