  • How do I check for leaks in the Huawei NetCol5000-A after installation?

    Before performing a leak check on the Huawei NetCol5000-A, ensure the following prerequisites are met:

    • Pipes from the indoor and outdoor units have been properly soldered.
    • The pressure gauge's measuring range is ≥ 4.0 MPa, and the leather hose's tolerance range is ≥ 4.5 MPa.
    • Do not remove the pressure gauge and leather hose when charging nitrogen to retain pressure.
    • Needle valve plugs are tightened.
    • Only nitrogen is allowed for leak checking.

    Procedure:

    1. Connect the pressure gauge, hose, reducing valve, and nitrogen to the device. Ensure the pressure gauge valves and reducing valve are closed.
    2. If a low-temperature component is not configured, charge nitrogen from the liquid pipe needle valve and low-pressure needle valve.
    3. Open the pressure gauge valve. Initially, loud noises of airflow will be generated, which should gradually disappear.
    4. After the air is exhausted, remove the pressure gauge and install the valve bonnet.
    5. Exhaust nitrogen from the liquid pipe low-pressure needle valve by repeating steps 1 to 3.

  • How do I vacuumize the Huawei NetCol5000-A cooling system?

    Before vacuumizing the Huawei NetCol5000-A cooling system, ensure that the refrigerant pipes have passed the air tightness test without leaks, and all connectors are secured.

    1. Check if the low-temperature component is connected.
    2. In the beginning, the vacuum pump will make loud noise and exhaust white smoke. If white smoke persists after 10 minutes, observe for another 10 minutes, as the cooling system might not be properly sealed or contain too much refrigerant/water.
    3. After 20 minutes, the pressure gauge pointer should be in the negative area, and the vacuum pump should make little noise. Close and open the pressure gauge several times; the pointer position and sound should not change significantly, otherwise, the cooling system may not be sealed.
    4. Vacuumize the cooling system for at least 80 minutes after confirming no leaks. The pressure displayed on the vacuum pump should be ≤ 60 Pa.
    5. Close all pressure gauge valves and the vacuum pump. Preserve the pressure for 10 minutes; it should be ≤ 90 Pa.

  • How do I charge refrigerant into the Huawei NetCol5000-A?

    Before charging refrigerant into the Huawei NetCol5000-A, ensure the cooling system does not leak and the vacuum level meets requirements. Calculate the required refrigerant amount using Table 5-1 or Table 5-2, and ensure air is exhausted from the hose connected to the refrigerant steel vessel.

    1. Remove the vacuum pump from the vacuumizing equipment and replace it with a refrigerant steel vessel.
    2. Partially open the refrigerant steel vessel valve and rubber tube nut. Tighten the nut when cold air comes out.
    3. Place the refrigerant steel vessel upside down on an electronic balance and clear the reading.
    4. Open pressure gauge valves and the refrigerant steel vessel valve to charge refrigerant.
    5. Charge at least another 10 kg refrigerant (15 kg for a low-temperature unit). The amount injected must not exceed the total injection amount. The remaining refrigerant will be charged during power-on and commissioning.
    6. After charging, close pressure gauge valves and the refrigerant steel vessel valve.

  • How do I connect the refrigerant pipes for the Huawei NetCol5000-A?

    When connecting the refrigerant pipes for the Huawei NetCol5000-A, follow these guidelines:

    • Weld Pipes for Outdoor Unit First: When connecting the indoor unit to the outdoor unit, it is advised to weld pipes for the outdoor unit first. If pipes are exposed for over 15 minutes, seal them to prevent dust and water.
    • Prevent Burning: During welding, avoid burning the bottom panel, top panel, side panels, other pipes, thermal insulation foam, cables, and labels. Use preventive measures like laying wet cloth around the welding position.
    • Avoid Contamination: After welding, avoid exposing refrigerant pipes for over 15 minutes to maintain system reliability. Seal holes after routing pipes and terminals to prevent foreign matter.
    • Clean Excessively Long Pipes: If welded copper pipes are excessively long or have bends, clean foreign matter inside the pipes with nitrogen.
    • Thermal Insulation: Wrap refrigerant pipes with thermal insulation foam.
    • Vibration Noise Reduction: To minimize noise due to vibration:
      • If the refrigerant pipe direction changes, add a support 500 mm away from the changing point.
      • If the refrigerant pipe is straight, add a support every 1500 mm.

    For more information, see page 58 of the manual.
