1. Remove the top hole cover.
2. Knock off the knock-out holes for the chilled water
inlet and outlet pipes.
3. To avoid deforming the pipe, use a 70# open-end
wrench to fix the pipe nut, use a 36# open-end
wrench to fix the plug, and then remove the plug.
4. Apply thread sealant evenly on the joints of external
screw threads, and install the pipes from inside out.
5. Use a 70# open-end wrench and an 18# pipe wrench
to fix the pipes.
(1) G 2 inch port with
inner threads (reserved
device port)
(2) Seamless steel pipe
with a G 2 inch external
threaded connector
(Optional) Leakage Test with Nitrogen

•
If the pressure decreases, apply soapy water on the pipes, especially pipe joints to check for
any leakage.
•
If the pressure is stable, wrap all pipes and connectors with thermal insulation foam.
•
Install a reducing valve at the outlet of the nitrogen cylinder. The outlet pressure of the reducing
valve must be not more than 0.8 MPa.
1. Rotate the chilled water valve to the maximum openness (100%).
2. Check that the needle valves and exhaust valves on the pipeline are closed.
3. Connect the reducing valve and nitrogen cylinder to the
following needle valve, inject 0.8 MPa (when the pressure is
stable) nitrogen, and leave them for 24 hours.
4. Then, check that the pressure reading on the pressure gauge
remains unchanged.
