Outdoor Unit Installation Dimensions
5.1
Space Requirements for Installing and Maintaining the Outdoor Unit
5.2
•To avoid fire disaster, install an outdoor unit in a dry and well-ventilated place without
flammable gas leakage.
•Select a place away from direct sunshine and radiation from other heat sources. If the
sunshine or heat radiation cannot be avoided, cover the outdoor unit.
•Do not install an outdoor unit in a place with much salt or corrosive gas.
•When installing the outdoor unit, ensure that the air intake vent and air exhaust vent of the
condenser are not dirty or blocked. Install an outdoor unit in a clean area that is away from
residential areas.

8
•At a high place with strong winds, install the outdoor unit against a wall to ensure the
normal operating of fans. Install baffle plates when necessary. Take this measure to prevent
wind from blowing down the outdoor unit.
•Try to install an outdoor unit against a wall. If the site conditions cannot meet the
requirements and the local outdoor temperature may be below –10°C (NetCol500-A018),
0°C (NetCol500-A020) or –10°C (NetCol500-A021), prepare and install an air baffle by
referring to the figures on the following slide. The air baffle height and width should be
greater than or equal to the outdoor unit height and width, respectively.
•indicates the wind direction.
•If the site installation environment is complicated and the preceding conditions are not met,
contact Huawei technical support.
Space requirements for a single outdoor unit
It is recommended that a
single outdoor be installed
against a wall.
If the air baffle is needed, place an air baffle at the air intake side of the outdoor unit based on
the following figure.
Space requirements for a single wall-mounted outdoor unit
•The bearing capacity of the support platform is more than 320 kg.
•Reserve no less than 300 mm from the left or right side of the outdoor unit for maintenance
personnel to walk.
•A mesh structure is recommended to avoid the air exhaust and intake of the smart cooling
product being affected by the guardrail structure.
•The picture is only for reference. Adjust based on the on-site situation if necessary.

1. The height deviation refers to the distance from the stop valves of the indoor unit to the stop
valves of the outdoor unit.
2. is a sign of a tilt, and it indicates that the scale of the pipe tilt is at least 1:200. The pipe
tilt direction should be consistent with the hypotenuse of the right triangle.
3. The refrigerant pipe should be wrapped with thermal insulation foam.
4. Keep the pipe dry during welding.
5. After the pipe between the indoor and outdoor units are welded, blow nitrogen from one end
into the pipe to clear foreign matter.
6. The welded joints cannot be exposed for a long period of time and must be sealed. If there is
foreign matter at the welding joints, clean the joints using anhydrous alcohol or a wet cloth,
and wait for the joints to dry up before welding.
7. Face-down bonding is forbidden.

1. Keep at least 25 mm between pipes.
2. When connecting the indoor and outdoor units, you are advised to connect pipes to the
outdoor unit first. Seal the pipe if the welding break will exceed 15 minutes to prevent dust
and water from entering the pipe.
3. Take appropriate sealing and protection measures when routing welded pipes through holes
to prevent air channel leaks and copper pipe damage. Otherwise, other components may be
damaged by foreign matter.
4. Avoid elbows and ensure that the connection between the indoor and outdoor units is the
shortest.

Upward pipe routing
1. When routing pipes upward inside an IT cabinet with the third or fourth indoor unit, remove
the cable ring from the pipe side in the rear of the cabinet.

12
2. Route pipes inside the cabinet.
Downward pipe routing

1. Connect the liquid pipe stop valve first, and then the gas pipe stop valve.
2. Tighten the liquid pipe stop valve using a 27# torque wrench to a torque of 35–37 N·m.
Tighten the gas pipe stop valve using a 36# torque wrench to a torque of 50–52 N·m
3. When tightening a stop valve using a torque wrench, secure the hex nut of the active
connector at the welded copper pipe to prevent the copper pipe from turning and further
deforming as the stop valve is being tightened.
4. Ensure that you tighten the valve to the specified torque. The failure torque for the nut of the
liquid pipe stop valve is 70 N·m and that for the nut of the gas pipe stop valve is 100 N·m.
The torque greater than the failure torque will damage the screw thread.

stop valves with thermal insulation foam
(the thickness is 5 mm).

•In upward pipe routing, install the check valve, engineering hose, and drainpipe connector by
performing steps 2–4. In downward pipe routing, install the drainpipe connector by
performing step 4.
•The drainpipe inside the indoor unit should be wrapped with the thermal insulation pipe in
accessories.
•The drainpipes must have gradients (> 1:50), and stagnant water is not allowed.

1. The stop valves for the gas pipe and liquid pipe on the indoor unit side are open, and those
on the outdoor unit side are closed.
2. (Leakage test with nitrogen) Inject nitrogen until the pressure reaches 3.0 MPa. Verify that
the pressure does not decrease after 24 hours at a stable ambient temperature. If any leak is
found after pressure preservation, check the pipe for leaks, especially the welding points and
stop valves.
3. (Vacuumizing) Replace the reducing valve and nitrogen cylinder with a vacuum pump.
Perform vacuumizing for at least 80 minutes and ensure that the final absolute pressure is
not greater than 60 Pa. When the final pressure does not decrease any more, continue to
vacuumize for 10 minutes. After vacuumizing is complete, close the vacuum pump and all
valves, and preserve the pressure for 10 minutes. Ensure that the absolute pressure does not
exceed 90 Pa. If the minimum reading of the pressure gauge is greater than 60 Pa, ensure
that the pointer stays at the smallest scale of the pressure gauge and preserve the pressure
for 1 hour. Then check that the pressure does not rise.
4. Open the stop valves for the gas pipe and liquid pipe of the outdoor unit.
•After the outdoor unit stop valve is opened, the refrigerant in the outdoor unit flows to the
engineering pipe and indoor unit pipe. When performing other operations, be careful to
prevent refrigerant from spraying out.
•After the vacuumization and before removing the rubber hose, ensure that there is positive
pressure inside the refrigerant pipe of the indoor unit. For detailed operations, see steps 1–4
in section "Commissioning Procedure".
9Leakage Test with Nitrogen and Vacuumizing

19
5. Remove the hose, pressure gauge, and vacuum pump.
6. Install the needle valve nut and rear cover nut of the indoor unit and outdoor unit.
7. Wrap the gas pipe stop valve, liquid pipe stop valve and the pipes connected to the stop valve
with thermal insulation foam.
1. Convert the length of components that cause partial resistance loss such as elbows into the
length equivalent to that of straight pipes, and add the equivalent length to the length of the
straight pipe between the indoor and outdoor units to obtain the total one-way pipe length
(L). L should be less than or equal to 80 meters. If L exceeds 80 meters, contact Huawei
technical support.
2. Charge extra refrigerant before power-on commissioning.
