There is no relation between the indication of suitability
and the pressure-temperature diagram, but together
they form the application profile.
Suitability
Pressure-temperature diagram
The pressure-temperature diagram is based on clean
water. At temperatures below freezing point, the dia-
gram is based on a mixture of water and glycol.
The figures in the following table refer to the pressure-
temperature diagram.
Note: Noise occurs especially at low speeds.
