R410A Refrigerant
2.1
Do not use unqualified refrigerant. Huawei will not be liable for any equipment damage caused
by unqualified refrigerant.
Refrigerant from name brands such as DuPont, Daikin, and Honeywell are recommended. 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 MPa = 10 bar
1 MPa ≈ 145 psi
1 MPa ≈ 10.2 kgf/cm2

Pipe Support
2.3
1. Height of the U-shaped clamp H = Pipe diameter (with thermal insulation foam) –5 mm.
2. The material for pipe supports and clamps should meet outdoor application requirements.
3. When the pipe is straight, add a support every 1500 mm. When the direction of the pipe is
changed, add a support at the position that is 500 mm away from the changing point.

Hoisting the Outdoor Unit
4.1
•Select a hoisting mode based on site requirements. Hoist the packed outdoor unit using two
ropes that are at least 8 meters and raise it gently while keeping its balance. If the outdoor
unit has no package or the package is damaged, protect the outdoor unit using pads or
packing materials during the hoisting.
•When an outdoor unit is to be installed on an external wall, route the ropes through the
inner side of the two bottom feet. When an outdoor unit is to be installed on a rooftop, route
the rope through the inner side of the two wooden supports. This measure avoids the rope
from slipping during hoisting.
•When an outdoor unit is to be installed on a rooftop, you do not have to remove the
package during the hoisting. Otherwise, the outdoor unit appearance may be slashed.
•Keep the outdoor unit vertical and exercise caution when transporting and hoisting it.
•Do not hold the fan guard on the shell. Otherwise, it will be deformed.
•Do not touch the fan blades using hand or any other object.
•Secure the outdoor unit to prevent it from falling down in an earthquake or a strong wind.

Space Requirements for Installing and Maintaining the Outdoor Unit
4.2
•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 clean areas that are 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 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) or 0°C(NetCol500-
A020), 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.
•If the site installation environment is complicated and the preceding conditions are not met,
contact Huawei technical support.
•indicates the wind direction.

A single outdoor is recommended to be installed against a wall.
Space Requirements for Single Outdoor Unit
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 maintaining the single wall-mounted outdoor unit
•The bearing capacity of the support platform is more than 230 kg.
•Reserve no less than 300 mm from the left or right side of the outdoor unit for
maintenance personnel to walk.
•Grid 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.
