between them should be less than or equal to 20 m. Install an oil trap every 6 m to 7.5 m
along the gas pipe in the vertical direction to ensure system reliability.
•If the indoor unit is placed higher than the outdoor unit, the maximum height deviation

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.

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.

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.
