O. The installer must ensure that the total pressure losses of the most unfavourable
hydraulic network, including the chiller, make it possible to obtain the desired operating point (see the
chiller characteristic curve: Consult the following paragraph about the characteristic curve of the chiller.
Characteristic curve concentration Mono Propylene Glycol 35%:
Note: To balance the network with various components, adjusters must be installed to adjust the load
losses to operate the pump in its curve and get the selected point. It is recommended to place a water
regulator on the water return to regulate the total HMT of the pump.
