Hyperchiller 450-760
pump data plate values: Pmin 1 bar/ Pmax 3 bar
adjust the valve outlet to give a pressure of 3 bar < P1< 5 bar
- Example n°2.
Conditions:
open circuit, pressure P0 = 0 bar
pump data plate values: Pmin 1 bar/ Pmax 3 bar
adjust the valve outlet to give a pressure of 1 bar < P1 < 3 bar
c) Verify correct operation of the pump similarly under normal run-
ning conditions.
Check also that the amperage of the pump is within the limits indi-
cated on the data plate.
d) Switch off the chiller and proceed to top up the hydraulic circuit at
the “SET” temperature.
e) Check that the temperature of the “treated” water does not fall
below 5 °C and that the ambient temperature in which the hydraulic
circuit operates does not fall below 5 °C. If the temperature is too
low, add the appropriate quantity of glycol, as explained under head-
ing 3.4.2
