4.5 (Optional) Leakage Test with Nitrogen
· If the pressure has fallen, apply soapy water on the pipes, especially pipe joints, to check for leakages. Rectify the leakages if any.
· If the pressure is stable, wrap all pipes and connectors with thermal insulation foam. · Install a reducing valve on the outlet of the nitrogen cylinder. Its outlet pressure must not
exceed 0.8 MPa. · In addition to the leakage test with nitrogen, there is the leakage test with water. You can
choose one test based on site requirements.
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.

4.6 (Optional) Leakage Test with Water

If the leakage test has been done with nitrogen, skip the test with water.

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.

4.7 Injecting Water to Expel Nitrogen

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.
1. Open the general water supply valve. 2. Press the button on the side of the actuator and
manually rotate the valve handle to the maximum in the specified direction. Check that the chilled water valve is in the open state (100%). 3. Slowly open the exhaust valve to let out gas. 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.

5 Installing Cables
5.1 Connecting the Equipotential Ground Cable and Power Cable

1. When routing the cables, wrap the section of all signal cables inside the smart cooling product with the corrugated pipes and route them out of the corresponding cable holes so that the strong- and weak-current cables are separated.
2. Route the power cable along the rear door post, and use cable ties to secure the cable to the post every 150­200 mm.

1. Connect the equipotential cable.

2. Connect the power cable.

5.2

(Optional) Connecting the Water Sensor

5.3

Installing T/H Sensors Outside Cabinets
