1. Features
New design
Flexible installation
Multi-refrigerant outlet pipe method: left\right\rear, more flexible for installation.
Flexsible piping connection
Refrigerant piping and condensate piping on the same side
High efficiency DC fan motor
The power consumption of DC driven VRF indoor units can be reduced up to 30% in comparison to
corresponding AC type.
Quiet operation
Adoption of the 2000 stages element positioning mechanical expansion valve, ensures precise flow control, as
well as lower modulation noise when EXV operating.
More smooth airflow with less turbulence. Owing to the multiple-blade fan and the air guide design, the airflow
is getting smoother and more comfortable.

8. Sound Levels
Test condition
Note:
1. Sound values are measured in a semi-anechoic room, at a position 1m below the air outlet both horizontally and vertically.
2. During actual operation, these values are normally somewhat higher as a result of ambient conditions.
