a) Replenish the system and water tank C21 with the Water filling pump P11.
b) Find an external water source (with a certain pressure), and connect the hose to Water
filling/drain port V104 on the container. Fill the connecting pipeline with Water for the first
Water filling (until water flows out). Find the Water filling port outside the container and plug
in the hose (at the side door of the container). Then, connect the external water tank to the
Water filling pump P11.
c) Open the exhaust valve of the Water filling pump (Allen wrench), switch to manual mode on
the touch screen, and open the solenoid valve V202. After water is discharged, close the
manual exhaust valve of the Water filling pump.
d) Close solenoid valve V202, switch to manual mode on the touch screen, and open the "Manual
Water Replenishment" mode "External → System" of the Water filling system, which means
adding Water to the system. Open "External → C21", which means adding Water to the water
tank C21 externally, as shown in Figure 7-14 Distribution of solenoid valves in the Water
filling system
e) .
f) When adding Water to the system, pay attention to whether there is water flowing out of the
exhaust valve of the cooling tower and the manual exhaust valve of the system. When there is
water flowing out, it indicates that the system has been fully filled. Then, close the manual
exhaust valve of the cooling tower, open the automatic exhaust valve, and close the manual
exhaust valve 701 of the system.
g) When the static pressure reaches 0.7 bar (refer to Figure 7-16, touch screen reading) or above,
the circulation pump can be started for 10 seconds (without stopping the Water filling pump),
and then the circulation pump can be stopped.
h) Continue to add Water and repeat for twice to ensure that 1.3-1.5 tons of coolant are added.
i) When the static pressure reaches 1.0-1.5 bar, stop adding Water (observe the reading of the
main interface pressure sensor PT02, as shown in Figure 7-16).
j) Turn on the circulation pump P01 again to circulate the coolant in the system, ensuring that all
automatic exhaust valves are in open state.
k) Due to the first Water filling and the presence of gas in the system, the discharge of gas during
the water pump circulation will cause a decrease in pressure in the system. At this time, the
Water filling function is turned on, and the water tank replenishes the system to ensure that the
return pressure is between 1.0 and 1.5 bar.
