Huawei FusionDC1000A - Fan

NO TE
Outdoor unit installation environments are classied as follows based on the harshness:
● Class A (controlled environment): indoor environments where the ambient temperature
and humidity are controlled, including rooms where people live.
● Class B (uncontrollable environment): indoor environments where the ambient
temperature and humidity are not controlled or general outdoor environments with
simple shielding measures where the humidity reaches 100% occasionally.
● Class C (harsh environment): marine environments within 3.7 km away from the coast
or outdoor land environments with simple shielding measures within 1.2 km away from
a pollution source.
● Class D (marine environment): environments within 500 m away from the coast.
The NetCol500-A040MS1E0 outdoor unit must not be used in class D
environments.
Features
● The outdoor unit is equipped with a
high-eciency variable-frequency drive
axial fan to implement large air ow, low noise, and high eciency.
● The outdoor unit provides good waterproof performance and meets the IPX5
requirements.
● The outdoor unit adopts the variable-frequency drive. The speed adjustment
of the outdoor fan ranges from 10% to 100%. The minimum operating
frequency of the fan is less than or equal to 5 Hz. The outdoor unit is running
more steadily at low loads.
● Using the galvanized sheet and surface phosphatization + powder coating
techniques, the outdoor unit adapts to harsh environments with its sound
rigidity and anticorrosion performance.
● Pressure preservation is performed on the condenser before delivery, and the
pipe ports are properly sealed to prevent foreign matter from entry.
