Huawei NetCol5000-A050 - Optional) Leakage Test with Water for the Water Cooling Module

NO TICE
The outlet pressure of the reducing valve should be within 3.0 MPa; otherwise,
components may be damaged.
Step 3 If the pressure decreases, nd out and repair the leakage point by using soap
water or a halogen leak detector. If the pressure is preserved properly, exhaust
nitrogen from the three positions shown in Figure 4-61.
NO TE
For scenarios where a container is transported without refrigerant, keep 0.2 to 0.6 MPa of
nitrogen in the pipeline.

4.8.10 (Optional) Leakage Test with Water for the Water
Cooling Module
Prerequisites
If a water cooling module is installed, you need to do leakage test with water.
NO TICE
Ensure that the indoor temperature is always above 0°C during the leakage test
with water; otherwise, the pipes may experience frost cracks. If the indoor
temperature is below 0°C, take anti-freezing measures for the pipes.
Procedure
Step 1 Manually open the chilled water valve (100%).
Figure 4-79 Opening the chilled water valve
Step 2 Open the main water inlet valve for the water cooling module.
Step 3 Gradually open the cooling water side needle valve. Air and chilled water ow out
of the needle valve together.
