Refrigerant R410A

2.1

Do not use unqualified refrigerant. Huawei will not be liable for any equipment damage caused by

unqualified refrigerant.

You can verify the refrigerant authenticity in the following ways:

1. Dial the refrigerant manufacturer's hotline to confirm the refrigerant manufacturer authenticity.

2. Place the refrigerant tank indoors for 24 hours. Use a point thermometer to measure the outer

surface temperature of the refrigerant tank (figure 1) , and connect a pressure gauge to the

tank to measure the internal pressure (figure 2). Find the saturation pressure corresponding to

the measured outer surface temperature from the table on the next page. If the deviation

between the saturation pressure and the measured internal pressure is greater than 0.2 MPa,

the refrigerant does not meet the requirements, and needs to be replaced.

1. Read the related user manual or instructions before installing the NetCol8000-A.

2. The unit in this document is a fully configured NetCol8000-A. 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 product. Otherwise, personal injuries and

device damage may be caused, which is beyond the smart cooling product warranty range.

1.Remove the six screws and then the beam. 2.Rotate the fan upward by 30 degrees, and pull

the rotating shaft of the fan to the outermost side.

4.After the fan rotates to the position shown in the

figure, push the fan back to the horizontal position.

5.Use a torque wrench to secure the two beams,

and interconnect the fan cables using the

interconnection terminal reserved in the cabinet.

3.Slowly rotate the fan by 90 degrees and ensure that

the rotating shaft of the fan is on the outermost side.

Exercise caution when handling the fan to avoid body

injury.

4Installing the Outdoor Unit

•Protective cardboard for fins must be removed after installation to protect people from injuries.

•The installation methods and distance requirements of installing NetCol500-A060, NetCol500-

A080 and NetCol500-A120 outdoor units are the same. This section describes how to install a

NetCol500-A060. The NetCol500-A110 outdoor unit does not support vertical installation.

•If the space does not meet the requirements of the recommended layout, you can use any of the

layouts (applicable only to NetCol500-A060) in user manual.

1. When outdoor unit is installed horizontally, the outdoor unit and the low-temperature component

must be at the same horizontal plane. When outdoor unit is installed vertically, the installing

horizontal plane of outdoor unit must not be lower than the installing horizontal plane of low-

temperature component, and the height difference cannot exceed 1.5 m.

2. When calculating the height difference, the compressor base is regarded as the baseline for the

indoor unit, and the condenser top is regarded as the baseline for the outdoor unit.

3. The inverted trap should be higher than the top copper pipe of the condenser.

4. When the indoor unit is higher than the outdoor unit, the maximum height difference is 8 m. When

the indoor unit is lower than the outdoor unit, the maximum height difference is 30 m.

5. When welding pipes, ensure that the pipes are dry. You are recommended to weld the pipes

between the indoor and outdoor units, then connect the two ends of the pipe to the indoor unit and

outdoor unit.

6. Use a rubber hose to connect the nitrogen cylinder which connecting the reducing valve and the

end of the copper pipe, then fill nitrogen at 0.03–0.05 MPa into the copper pipe to avoid internal

oxidation.

7. After the pipe in the middle is welded, charge nitrogen into the pipe from one pipe end to clear the

foreign matter inside.

8. Do not expose welding positions to the environment for a long time. Take sealing measures for

welding positions. If foreign matter exists at the welding position, rubber it out using non-water

alcohol or damp cloth before the welding.

9. Take protective measures, such as spreading a piece of wet cloth, around the welding position, to

avoid burning the bottom panel, top panel, side panel, internal components, needle valves, other

pipes, thermal insulation foam, power cables, labels, and tags.
