4. Initial Startup
4.3 Coolant Line Purge
You must carry out the following air purge procedures to purge the air in the pipe:
1
Open the shutoff valve and the bypass valve.
2
Rotate the outlet water pipe's manual exhaust valve counterclockwise.
(Figure 4-3: Open the outlet water pipe's manual exhaust valve—illustration shown with top cover removed)
3
Open the water inlet's user-supplied valve to let the water slowly flow into the pipe. After the water flows into the pipe, the air will be
squeezed out.
4
After 6~7 seconds, when the air is exhausted and the water begins to discharge from the pipe, close the valve in the reverse
method in which it was opened.
Note: Do not perform the air exhaust procedures after making any changes in the pipeline structure. It is recommended to install an automatic
exhaust valve for external piping. Refer to 3.7 External Piping.
