6.11 NORMAL START-UP
The start-up procedure is indicated below. The flow diagram shows the
variables based on the characteristics of the machine and the water
circuit.
During start-up, it’s essential that the plant water temperature
stabilizes to the set point value before activating CCUs.
1. Check that CCUs are OFF (fans OFF)

circuit’s
pump
4.
Wait until the
secondary
circuit reaches the set
point temperature
5. Wait until the
secondary
circuit reaches the set
point temperature
Turn on CCUs (fans turning on)
WARNING - CAUTION
Do not change the plant loads suddenly.
If there are several distinct areas, spread the CCU activation,
so that the machine can adjust to the increase in load step-by-step.
