1Installing the Cabinet

1. Determine the cabinet position based

on the engineering layout diagram.

2. Place the cabinet at the correct

installation position.

3. Level the cabinet using a wrench.

•Use a measuring tape to check

that the vertical distance between

the top of the 2000 mm high

cabinet and the floor is 2000 mm

(+3 mm). Then use a level to

check that the cabinet is level.

•Do not remove the anchor bolts.

Otherwise, rework is required if

the cabinet height does not meet

requirements.

2Installing an Indoor Unit

1. Remove filler panels.

2. Push the indoor unit into the bottom of the cabinet along the guide rails.

Hardware Installation

3Exhausting Nitrogen from an Indoor Unit

1. Open the stop valve for the gas pipe

of the indoor unit.

2. Loosen the needle valve nut, connect a rubber hose

and a pressure gauge, and slowly exhaust nitrogen.

3. After the airflow sound disappears, reinstall the

needle valve nut.

4Installing an Outdoor Unit

•To avoid a fire disaster, install an outdoor unit in a dry and well-ventilated place without

flammable gas leakage.

•Select a place away from direct sunlight and radiation from other heat sources. If the

sunlight 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.

•At a high place with strong winds, install the outdoor unit against a wall to ensure the

normal operating of fans. Install a baffle plate when necessary to prevent the outdoor unit

from toppling in strong winds.

•Install an outdoor unit against a wall if possible. If the site conditions cannot meet the

requirements and the local outdoor temperature may be below –10°C, install a baffle plate

by referring to the space requirements. The baffle plate height and width should be greater

than or equal to the outdoor unit height and width, respectively.

•If the site installation environment is complicated and the preceding conditions are not met,

contact Huawei technical support.

(3) Liquid pipe needle valve

Space Requirements

1. Determine the four mounting holes of the outdoor unit and drill holes in the

concrete base. Then, secure the outdoor unit to the concrete base using expansion

bolts.

5Connecting Pipes

Lay out pipes based on site requirements and the following principles:

•The length of a pipe should be as short as possible. The recommended length is within 10 m.

Avoid unnecessary turnings, lifting, and falling.

•Minimize the height difference between the indoor and outdoor units.

•Minimize the number of bends for pipes.

•Release nitrogen from the indoor unit before connecting it.

•Prepare copper pipes for connecting indoor and outdoor units. Ensure that the copper pipes

are clean, free from impurities and moisture.

•If a copper pipe needs to be routed through the wall, seal both ends of the copper pipe

before routing it through the wall.

•After a pipe is connected, charge dry nitrogen, test leakage, and vacuumize the pipe.

1. Obtain tools.

2. Drill holes in the wall.

3. Install the refrigerant pipe and

check whether the pipe thread

is sealed for protection.

4. Connect the threaded connector.

5. If a low-temperature component is configured, connect the pipe to the

low-temperature component.

6Connecting a Water Pipe

Top Piping Bottom Piping

1. Connect the drainpipe. 1. Connect the drainpipe connector to the other end of

the drainpipe.

2. Remove the baffle plate from the water pipe hole at

the bottom of the cabinet, and install the drainpipe.

•After connecting the drainpipe, power on

the smart cooling product, add water to the

water pan until the low float switch is

raised, and check whether drainage is

normal.

•Ensure that the condensate pipe is not bent

during installation and connection.

7Installing Cables

•To ensure personal safety, ensure that the metal shell of the smart cooling product is

properly connected to the ground electrode after installing the product. Ground the smart

cooling product properly during installation.

•The power input of all indoor units is single-phase, three-wire (L+N+PE).

•The cables for connecting the indoor and outdoor units need to be provided by the customer.

•The supply voltage must be within the normal range (187 V to 253 V).

•The original cables in the unit cannot be changed under any circumstances.

•Do not reversely connect the L and N cables.

•Ensure that all wiring terminals are securely installed.

•All safety protection devices in the unit are set before delivery. Do not adjust them by

yourself.

•Cables must be routed through protective tubes for protection.

8Nitrogen Injection, Pressure Preservation, and

Vacuumization

1. Open the stop valve for the gas pipe of the indoor unit.

2. Connect the pressure gauge, rubber hose, and nitrogen cylinder. Ensure that the outlet

pressure of the reducing valve is less than or equal to 3.5 MPa.

3. Inject 3.5 MPa nitrogen and preserve the pressure for 24 hours. The system pressure should

stay constant under unchanging ambient temperature conditions. If there is a considerable

temperature change and the pressure changes, perform the test again.

4. If welding defects exist, locate and repair the leak point. If the pressure does not change,

exhaust the nitrogen through the injection needle valve.

•The measuring range of the

pressure gauge must be greater

than or equal to 4.0 MPa, and the

rubber hose must withstand a

pressure of at least 4.5 MPa.

•During pressure preservation, do not

remove the rubber hose and

pressure gauge; otherwise, nitrogen

may leak.

•Do not use compressed air because

water and impurities in the air

affect the system operation.

•Do not use oxygen or acetylene for

a leakage test.

5. Connect a pressure gauge to the gas pipe needle

valve and liquid pipe needle valve of the indoor

unit, and connect a vacuum pump.

6. Check that all pressure gauge valves are open.

7. Check that the time for vacuumization is 80

minutes or longer after ensuring that the cooling

system does not leak, and that the pressure

displayed on the vacuum pump is less than or

equal to 60 Pa (absolute pressure). When the

pressure stops dropping, pump for another 10

minutes.

8. After vacuumization, close all valves of the

pressure gauge and the vacuum pump without

disconnecting the pump. Preserve the pressure

for 10 minutes, and verify that the absolute

pressure of the cooling system is not greater

than 90 Pa (absolute pressure).

9. After ensuring that the pressure gauge has no

obvious increase, open the stop valves for the

gas pipe and liquid pipe of the outdoor unit.

10.Add refrigerant oil.
