4. Adjust the gas releasing speed until no gas flows
out of the valve. Then close the exhaust valve.
5. Manually close the chilled water valve.
1. Rotate the chilled water valve to the
maximum (100%).
2. Check that the needle and exhaust valves
on the pipeline are closed.
3. Connect a reducing valve and a nitrogen
cylinder at the needle valve position shown
in the figure, charge 0.8 MPa of nitrogen
(when the pressure is stable), and leave
them for 24 hours.
4. Check for pressure change after 24 hours.
(Optional) Leakage Test with Water
4.7
Manually open the chilled water valve. Inject water to 0.8 MPa, and preserve the pressure for 24
hours. Then connect a pressure gauge to a needle valve on the pipeline to measure the pressure. If
the reading remains unchanged, the pipe is not leaking. You can perform the following operations.
Clean the main pipe beforehand to avoid
blockage of the heat exchanger due to foreign
construction matter. Close the isolation valve on
the water inlet and outlet pipes before the
cleaning.
