Normal Start-Up - RC GROUP TRIPACK Series Installation, Use And Maintenance Manual

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.
NO
Is the water circuit
divided into primary
NO
and secondary
circuit?
2.
Start the circuit's
pump
3.
Wait for at least 1 min
and start the
machine.
4.
Wait until the circuit
reaches the set point
temperature
If there are several distinct areas, spread the CCU activation,
so that the machine can adjust to the increase in load step-by-step.
