Refrigerant R410A2.1
Do not use inferior refrigerant. Otherwise, Huawei has no responsibility for the damage caused by
the inferior refrigerant.
Refrigerant Authenticity Verification Method:
1. Dial the hotline of the refrigerant producer to confirm its reliability.
2. Put the refrigerant indoor for 24 hours. Then use a thermometer to measure the external
surface temperature of the refrigerant cylinder (figure 1) , and connect a pressure gauge to the
cylinder to measure its internal pressure (figure 2) . Look up the following table for the
saturation pressure that corresponds to the external surface temperature, and calculate the
deviation from the internal pressure. If the deviation is more than 0.2 MPa, the refrigerant is
not in good condition. Replace it.

1. Read the related user manual or instructions before installing the NetCol5000-A.
2. The unit in this document is a fully configured NetCol5000-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.

•Protective cardboard for fins must be removed after installation to protect people from injuries.
•The installation methods of installing NetCol500-A060 and NetCol500-A080 outdoor units are
the same. This section describes how to install a NetCol500-A060.
•If the space does not meet the requirements of the recommended layout, you can use any of
the following layouts (applicable only to NetCol500-A060).
Make sure that no shelter is above the outdoor unit.

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. Whencalculatingthe height difference, the compressor base is regarded as the baseline for the indoor
unit, and the condenser top is regardedas the baseline for the outdoor unit.
3. The inverted trap should be higherthan the top copper pipe of the condenser.
Scenario2: Horizontal concrete base installation
Scenario 3: Stack scenario
A maximum of four layers of water-cooling modules can be stacked. If four layers of water cooling
modules are stacked, the minimum floor height is 3 m.
Secure the water-cooling module using bolts in the fitting bag on four mounting holes.
Scenario 1: Horizontal
installation top view
Installation environment: enclosed indoor environment in which the temperature and humidity can be
controlled within the ranges of 4℃to 45℃and 5% RH to 90% RH respectively. If the indoor
installation position is ventilated, it should be more than 5 km away from the sea or pollution sources
(such as salt lakes, chemical plants, mineral plants, thermal power plants, and coal mines).

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 differenceis 30 m.
5. Whenwelding pipes, ensure that the pipes are dry. You are recommendedto 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, chargenitrogen into the pipe from one pipe end to clear the
foreign matter inside.
8. Do not expose welding positionsto the environment for a long time. Take sealing measuresfor welding
positions. If foreign matter exists at the welding position, rubber it out using non-water alcohol or damp
cloth before the welding.
Discharging Nitrogen
7.2
Separately exhaust nitrogen from the three needle valves. Separately exhaust nitrogen from the
two needle valves for the water cooling module. When exhausting nitrogen, do not remove the
valve plug in case of losing or damaging it.

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.

1. Clean the water inlet engineering pipes to avoid impurities
entering into the humidifier.
2. When routing pipes from the top, do not route the pipes
over servers or other devices to protect them from being
affected by pipe leaks.
3. Wrap each part of the pipes with thermal insulation foam.
4. Use supports to secure pipes.
