Quick Guide

Preparing an Indoor Unit Base
2.1
1. Shock absorption bars (EPDM rubber, 5 mm
thick) need to be installed between the
ground and the base.
2. The base should be at least 250 mm in height.
3. You are advised to use angle steel, square
steel or channel steel. Width of 50 mm and
thickness of 3 mm to 5 mm is recommended.
4. When the width of angle steel is more than 50
mm, it is interfering with the cable routing
holes. Cut out the part on the angle steel to
avoid interfering. If the width is less than or
equal to 50 mm, skip this step.
NOTE
3Installing the Equipment
1. Read the related user manual or instructions before installing the NetCol5000-C.
2. The unit in this document is a fully configured NetCol5000-C. If some components are not
configured, skip the corresponding steps.
3. You are recommended to use tools that are fully insulated when installing devices.
4. Only engineers from the manufacturer or engineers certified by the agent are allowed to install,
commission, and maintain smart cooling products. Otherwise, personal injuries and device
damage may be caused, which is beyond the smart cooling product warranty range.

1. The equipment has been injected with
0.3–0.5 MPa of nitrogen before delivery.
If no nitrogen is discharged, contact
Huawei technical support.
2. You can open or close the exhaust valve
using a flat-head screwdriver.

4Installing Pipes
1. A 1:100 tilt should be reserved for the main drainpipe.
2. Keep a clearance of at least 25 mm between pipes. Secure the pipes to supports every a
certain distance.
3. Clean the water inlet engineering pipes to avoid impurities entering into the humidifier.
4. A reducing valve must be installed if the inlet water pressure exceeds 0.7 MPa.
5. Pipes should be wrapped with thermal insulation foam along the route.

recommended torque is 5 N·m.
2. When metal materials are used, the recommended torque is 10

(Optional) Leakage Test with Nitrogen
4.5
•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.

Injecting Water to Expel Nitrogen
4.6
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.
(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.
If the leakage test has been done with nitrogen, skip the test with water.

5Installing Cables
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 150–200 mm.
